This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2. Building on FreeBSD is the same as building on Linux, but 'make' is replaced with 'gmake'.<br /> <br /> '''Tested GCC Versions'''<br /> * GCC12 Works<br /> * GCC14 Fails, run-time errors.<br /> * GCC15 Fails, compile-time errors.<br /> <br /> '''Debian 12 Dependencies'''<br /> <br /> <br /> apt install git build-essential m4 bison flex zlib1g-dev libncurses-dev imagemagick python-is-python3 gnat libssl-dev pkg-config curl<br /> <br /> <br /> '''FreeBSD 14.2 Dependencies'''<br /> <br /> &lt;nowiki&gt;<br /> ### This list may be incomplete<br /> pkg install git bash gmake gcc12 m4 bison ImageMagick7 python autoconf automake gettext-tools gnu-unifont<br /> &lt;/nowiki&gt;<br /> <br /> '''Configuring and Compiling'''<br /> <br /> &lt;nowiki&gt;<br /> ### Fetch coreboot-15h source<br /> # Tip: Add the '--depth=1' argument to save bandwidth.

2010&lt;ref&gt;https://www.techpowerup.com/119540/asus-releases-kgpe-d16-socket-g34-motherboard-for-12-core-amd-opteron-processors&lt;/ref&gt;, for use with [[Socket G34]] Opteron processors. Originally sold as a standalone board in a mostly-standard SSI EEB form factor, and intended for both desktop and rack-mounted uses, the KGPE-D16 is popular among enthusiasts as a relatively versatile and workstation-friendly G34 platform.<br /> <br /> Ports of [[coreboot]] and [[OpenBMC]] to the D16 were initially developed by [[Raptor Engineering]] between 2015 and 2017. Among major coreboot versions, it was first supported in coreboot 4.2 in October 2015, and last supported in coreboot 4.11 in November 2019. The port was never completed and was removed in coreboot 4.12 due to lack of maintenance. Between 2021 and 2022, after seeking funding for such an effort for several years, [[3mdeb]] developed an out-of-tree fork of coreboot 4.15 for the board under their Dasharo brand. The effort to complete and re-upstream the [[Raptor Engineering|Raptor]] port was unsuccessful and officially abandoned in August 2025&lt;ref&gt;https://github.com/Dasharo/dasharo-issues/issues/478&lt;/ref&gt;.<br /> <br /> An independent port of [[coreboot]] to the D16, using AMD's open source AGESA and CIMx codebases, was released in October 2025 by 15h.org. It is currently the most complete and only actively developed port of [[coreboot]] for the KGPE-D16.<br /> <br /> == Open Source Firmware ==<br /> Open source firmware for the KGPE-D16 is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization. The git repository for the firmware can be reviewed [https://git.15h.org/mrothfuss/coreboot-15h here].<br /> <br /> === coreboot-15h ===<br /> {{Excerpt|Coreboot-15h|[[ASUS KGPE-D16]]|hat=no|bold=1}}<br /> <br /> === Display Output ===<br /> [[File:KGPE-D16 VGA Jumper.png|frameless|400x400px]]<br /> <br /> The mainboard VGA_SW1 jumper determines whether the onboard VGA ([[ASPEED AST2050|AST2050]]) or a PCIe GPU will be used as the bootup display. Set VGA_SW1 to &quot;Enable&quot; to use the onboard VGA. Set VGA_SW1 to &quot;Disable&quot; to use a PCIe GPU. Once your OS has booted, drivers for any GPU of your choice can be used to setup a display. For blob-free opertions, it is recommended to use the onboard VGA in textmode for the bootup display but then switch to a FOSS driver (ie: amdgpu) for the user interface.<br /> <br /> ==== Onboard VGA Output ====<br /> The onboard VGA, [[ASPEED AST2050|AST2050]], can be setup with a closed-source VGABIOS (full VGA support) or with an open-source coreboot driver (textmode VGA support). A compatible display, generally an old VGA monitor, will be required to use the open-source driver. The closed-source VGABIOS is only included in coreboot-15h release ROMs with the &quot;VGA-OpROMs&quot; tag.<br /> <br /> ==== PCIe GPU Output ====<br /> To use a PCIe GPU as the bootup display, PCIe Option ROMs must be executed by SeaBIOS. This is enabled in 15h.org release ROMs with the &quot;VGA-OpROMs&quot; tag. The relevant coreboot-15h menuconfig option for SeaBIOS is &quot;Payload &gt; Execute PCIe Option ROMs&quot;. The &quot;VGA Only&quot; option is the recommended setting when using a PCIe GPU as the bootup display.<br /> <br /> === Fan Output ===<br /> [[File:KGPE-D16 Fan Jumper.png|frameless|400x400px]]<br /> <br /> The [[coreboot-15h]] release ROMs for KGPE-D16 are configured to adjust fan speeds based on temperatures measured at the CPUs and the Northbridge. The KGPE-D16 has two fan zones: one for CPU fans (CPUFAN_SEL1) and one for chassis fans (CHAFAN_SEL1). These can be assigned to either 4-pin (PWM regulated) or 3-pin (Voltage regulated) fan control outputs. The 4-pin (PWM regulation) mode offers better control over fan speeds and is the recommended setting for both fan zones. It is important to not use a 4-pin fan in a zone configured for 3-pin control; the fan will receive both voltage regulation and PWM regulation, causing irregular fan speeds. For quiet 3-pin chassis fans, it is recommended to leave the CHAFAN_SEL1 set to 4-pin (PWM regulation) mode. This will let the 3-pin chassis fans operate at 100% speed regardless of thermal readings.<br /> <br /> === Missing Features ===<br /> * SeaBIOS does not respond to keyboards behind a USB hub.<br /> * Hibernation and Suspend/Resume are unsupported.<br /> * Opteron 6100 series CPUs are unsupported.<br /> * ASUS MIO audio cards are untested.<br /> <br /> === Flashing ===<br /> To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required. The DIP-8 flash chip is located at the bottom right corner of the board (labeled BIOS in the motherboard diagram). A 3.3V CH341a programmer can be used to flash coreboot onto the KGPE-D16. When switching to coreboot-15h from the OEM BIOS or coreboot, clearing the CMOS is required.<br /> <br /> '''Clearing the CMOS'''<br /> # Turn off the computer, disconnect the power cord and any powered peripherals (Monitors, USB devices, etc)<br /> # Move the CLRTC1 jumper (located under PCIe Slot 2) to positions 2-3<br /> # Wait 20 seconds<br /> # Restore the CLRTC1 jumper to positions 1-2<br /> # Connect the power cord and turn on the computer<br /> <br /> == Deployed Systems ==<br /> * [[Qubesotron]]<br /> * [[EmCAST]]<br /> * [[Atlas]]<br /> * [[Orion]]<br /> * [[Unc]]<br /> * [[Ganoo]]<br /> * [[RAD01]]<br /> * [[RAD03]]<br /> <br /> Outside of the 15h.org community, it is known that, at least as of 2022, the [https://fsf.org Free Software Foundation] uses KGPE-D16s with 6200-series Opterons [https://www.fsf.org/blogs/sysadmin/closing-in-on-fully-free-bioses-with-the-fsf-tech-team for their servers].<br /> <br /> == Motherboard Diagrams ==<br /> [[File:KGPE-D16 Diagram.png|frameless|400x400px]]<br /> [[File:KGPE-D16 BlockDiagram.png|frameless|400x400px]]<br /> <br /> There is an undocumented 9-pin VGA header next to the rear-IO VGA port.

The differences between the four revisions have not been disclosed. The more recent boards (1.04 and 1.05) are generally in better condition and are recommended. Board revisions 1.03G, 1.04, and 1.05 are known to perform equally well when in similar condition. No community members have tested a 1.02G revision board. The KGPE-D16 can be found rebranded for distribution in China (KGPE-D16/CHN). The CHN variant can also run coreboot like the other KGPE-D16 variants, there are no known differences.<br /> <br /> == Board View ==<br /> Board views are available for the KGPE-D16.

Originally sold as a standalone board in a mostly-standard SSI EEB form factor, and intended for both desktop and rack-mounted uses, the KGPE-D16 is popular among enthusiasts as a relatively versatile and workstation-friendly G34 platform.<br /> <br /> Ports of [[coreboot]] and [[OpenBMC]] to the D16 were initially developed by [[Raptor Engineering]] between 2015 and 2017. Among major coreboot versions, it was first supported in coreboot 4.2 in October 2015, and last supported in coreboot 4.11 in November 2019. The port was never completed and was removed in coreboot 4.12 due to lack of maintenance. Between 2021 and 2022, after seeking funding for such an effort for several years, [[3mdeb]] developed an out-of-tree fork of coreboot 4.15 for the board under their Dasharo brand. The effort to complete and re-upstream the [[Raptor Engineering|Raptor]] port was unsuccessful and officially abandoned in August 2025&lt;ref&gt;https://github.com/Dasharo/dasharo-issues/issues/478&lt;/ref&gt;.<br /> <br /> An independent port of [[coreboot]] to the D16, using AMD's open source AGESA and CIMx codebases, was released in October 2025 by 15h.org. It is currently the most complete and only actively developed port of [[coreboot]] for the KGPE-D16.<br /> <br /> == Open Source Firmware ==<br /> Open source firmware for the KGPE-D16 is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization. The git repository for the firmware can be reviewed [https://git.15h.org/mrothfuss/coreboot-15h here].<br /> <br /> === coreboot-15h ===<br /> {{Excerpt|Coreboot-15h|[[ASUS KGPE-D16]]|hat=no|bold=1}}<br /> <br /> === Display Output ===<br /> [[File:KGPE-D16 VGA Jumper.png|frameless|400x400px]]<br /> <br /> The mainboard VGA_SW1 jumper determines whether the onboard VGA ([[ASPEED AST2050|AST2050]]) or a PCIe GPU will be used as the bootup display. Set VGA_SW1 to &quot;Enable&quot; to use the onboard VGA. Set VGA_SW1 to &quot;Disable&quot; to use a PCIe GPU. Once your OS has booted, drivers for any GPU of your choice can be used to setup a display. For blob-free opertions, it is recommended to use the onboard VGA in textmode for the bootup display but then switch to a FOSS driver (ie: amdgpu) for the user interface.<br /> <br /> ==== Onboard VGA Output ====<br /> The onboard VGA, [[ASPEED AST2050|AST2050]], can be setup with a closed-source VGABIOS (full VGA support) or with an open-source coreboot driver (textmode VGA support). A compatible display, generally an old VGA monitor, will be required to use the open-source driver. The closed-source VGABIOS is only included in coreboot-15h release ROMs with the &quot;VGA-OpROMs&quot; tag.<br /> <br /> ==== PCIe GPU Output ====<br /> To use a PCIe GPU as the bootup display, PCIe Option ROMs must be executed by SeaBIOS. This is enabled in 15h.org release ROMs with the &quot;VGA-OpROMs&quot; tag. The relevant coreboot-15h menuconfig option for SeaBIOS is &quot;Payload &gt; Execute PCIe Option ROMs&quot;. The &quot;VGA Only&quot; option is the recommended setting when using a PCIe GPU as the bootup display.<br /> <br /> === Fan Output ===<br /> [[File:KGPE-D16 Fan Jumper.png|frameless|400x400px]]<br /> <br /> The [[coreboot-15h]] release ROMs for KGPE-D16 are configured to adjust fan speeds based on temperatures measured at the CPUs and the Northbridge. The KGPE-D16 has two fan zones: one for CPU fans (CPUFAN_SEL1) and one for chassis fans (CHAFAN_SEL1). These can be assigned to either 4-pin (PWM regulated) or 3-pin (Voltage regulated) fan control outputs. The 4-pin (PWM regulation) mode offers better control over fan speeds and is the recommended setting for both fan zones. It is important to not use a 4-pin fan in a zone configured for 3-pin control; the fan will receive both voltage regulation and PWM regulation, causing irregular fan speeds. For quiet 3-pin chassis fans, it is recommended to leave the CHAFAN_SEL1 set to 4-pin (PWM regulation) mode. This will let the 3-pin chassis fans operate at 100% speed regardless of thermal readings.<br /> <br /> === Missing Features ===<br /> * SeaBIOS does not respond to keyboards behind a USB hub.<br /> * Hibernation and Suspend/Resume are unsupported.<br /> * Opteron 6100 series CPUs are unsupported.<br /> * ASUS MIO audio cards are untested.<br /> <br /> === Flashing ===<br /> To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required.

The file may need to be edited to accommodate the exact placement of your 40mm fan cable (the provided design has a cable hole at the bottom right position).<br /> <br /> [https://15h.org/images/8/8a/KGPE-D16_Chipsetfan_40mm.stl KGPE-D16_Chipsetfan_40mm.stl]<br /> <br /> [https://15h.org/images/9/98/KGPE-D16_Chipsetfan_40mm.blend KGPE-D16_Chipsetfan_40mm.blend]<br /> <br /> === Chipset Thermal Paste ===<br /> [[File:KGPE-D16_North_bridge_picture.png|frameless|300px]]<br /> <br /> Removing the NB/SB heatsinks to reapply the thermal paste can be daunting due to glue used for the NB heatsink, limited wiggle room, and marginal benefit.

When two of these fan mounts are attached to a Noctua NF-A8 fan, they will be spaced correctly to snap onto the KGPE-D16 RAM clips (white). These clips vary between boards.

This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

2026-04-26T19:23:15Z <p>Mrothfuss: /* Supermicro H8SGL */</p> <hr /> <div>{{lowercase title}}<br /> <br /> '''coreboot-15h''', also known as '''Mike's coreboot''', is a distribution of [[coreboot]] for various [[Family 15h]] motherboards, developed by [[User:Mrothfuss|mrothfuss]], using AMD's open-source fam15h AGESA and CIMX for initialization. This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

2026-04-26T19:22:13Z <p>Mrothfuss: /* Supermicro H8QG6 */</p> <hr /> <div>{{lowercase title}}<br /> <br /> '''coreboot-15h''', also known as '''Mike's coreboot''', is a distribution of [[coreboot]] for various [[Family 15h]] motherboards, developed by [[User:Mrothfuss|mrothfuss]], using AMD's open-source fam15h AGESA and CIMX for initialization. This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

various [[Family 15h]] motherboards, developed by [[User:Mrothfuss|mrothfuss]], using AMD's open-source fam15h AGESA and CIMX for initialization. This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

<p>Mrothfuss: /* ASUS KGPE-D16 */</p> <hr /> <div>{{lowercase title}}<br /> <br /> '''coreboot-15h''', also known as '''Mike's coreboot''', is a distribution of [[coreboot]] for various [[Family 15h]] motherboards, developed by [[User:Mrothfuss|mrothfuss]], using AMD's open-source fam15h AGESA and CIMX for initialization. This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

Originally sold as a standalone board in a mostly-standard SSI EEB form factor, and intended for both desktop and rack-mounted uses, the KGPE-D16 is popular among enthusiasts as a relatively versatile and workstation-friendly G34 platform.<br /> <br /> Ports of [[coreboot]] and [[OpenBMC]] to the D16 were initially developed by [[Raptor Engineering]] between 2015 and 2017. Among major coreboot versions, it was first supported in coreboot 4.2 in October 2015, and last supported in coreboot 4.11 in November 2019. The port was never completed and was removed in coreboot 4.12 due to lack of maintenance. Between 2021 and 2022, after seeking funding for such an effort for several years, [[3mdeb]] developed an out-of-tree fork of coreboot 4.15 for the board under their Dasharo brand. The effort to complete and re-upstream the [[Raptor Engineering|Raptor]] port was unsuccessful and officially abandoned in August 2025&lt;ref&gt;https://github.com/Dasharo/dasharo-issues/issues/478&lt;/ref&gt;.<br /> <br /> An independent port of [[coreboot]] to the D16, using AMD's open source AGESA and CIMx codebases, was released in October 2025 by 15h.org. It is currently the most complete and only actively developed port of [[coreboot]] for the KGPE-D16.<br /> <br /> == Open Source Firmware ==<br /> Open source firmware for the KGPE-D16 is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization. The git repository for the firmware can be reviewed [https://git.15h.org/mrothfuss/coreboot-15h here].<br /> <br /> === coreboot-15h ===<br /> {{Excerpt|Coreboot-15h|[[ASUS KGPE-D16]]|hat=no|bold=1}}<br /> <br /> === Display Output ===<br /> [[File:KGPE-D16 VGA Jumper.png|frameless|400x400px]]<br /> <br /> The mainboard VGA_SW1 jumper determines whether the onboard VGA ([[ASPEED AST2050|AST2050]]) or a PCIe GPU will be used as the bootup display. Set VGA_SW1 to &quot;Enable&quot; to use the onboard VGA. Set VGA_SW1 to &quot;Disable&quot; to use a PCIe GPU. Once your OS has booted, drivers for any GPU of your choice can be used to setup a display. For blob-free opertions, it is recommended to use the onboard VGA in textmode for the bootup display but then switch to a FOSS driver (ie: amdgpu) for the user interface.<br /> <br /> ==== Onboard VGA Output ====<br /> The onboard VGA, [[ASPEED AST2050|AST2050]], can be setup with a closed-source VGABIOS (full VGA support) or with an open-source coreboot driver (textmode VGA support). A compatible display, generally an old VGA monitor, will be required to use the open-source driver. The closed-source VGABIOS is only included in coreboot-15h release ROMs with the &quot;VGA-OpROMs&quot; tag.<br /> <br /> ==== PCIe GPU Output ====<br /> To use a PCIe GPU as the bootup display, PCIe Option ROMs must be executed by SeaBIOS. This is enabled in 15h.org release ROMs with the &quot;VGA-OpROMs&quot; tag. The relevant coreboot-15h menuconfig option for SeaBIOS is &quot;Payload &gt; Execute PCIe Option ROMs&quot;. The &quot;VGA Only&quot; option is the recommended setting when using a PCIe GPU as the bootup display.<br /> <br /> === Fan Output ===<br /> [[File:KGPE-D16 Fan Jumper.png|frameless|400x400px]]<br /> <br /> The [[coreboot-15h]] release ROMs for KGPE-D16 are configured to adjust fan speeds based on temperatures measured at the CPUs and the Northbridge. The KGPE-D16 has two fan zones: one for CPU fans (CPUFAN_SEL1) and one for chassis fans (CHAFAN_SEL1). These can be assigned to either 4-pin (PWM regulated) or 3-pin (Voltage regulated) fan control outputs. The 4-pin (PWM regulation) mode offers better control over fan speeds and is the recommended setting for both fan zones. It is important to not use a 4-pin fan in a zone configured for 3-pin control; the fan will receive both voltage regulation and PWM regulation, causing irregular fan speeds. For quiet 3-pin chassis fans, it is recommended to leave the CHAFAN_SEL1 set to 4-pin (PWM regulation) mode. This will let the 3-pin chassis fans operate at 100% speed regardless of thermal readings.<br /> <br /> === Missing Features ===<br /> * The two black SATA ports are inactive.<br /> * TPM support is in progress.<br /> * SeaBIOS does not respond to keyboards behind a USB hub.<br /> * S3 Suspend/Resume is unsupported.<br /> * Opteron 6100 series CPUs are unsupported.<br /> * ASUS MIO audio cards are untested.<br /> <br /> === Flashing ===<br /> To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required.

Originally sold as a standalone board in a mostly-standard SSI EEB form factor, and intended for both desktop and rack-mounted uses, the KGPE-D16 is popular among enthusiasts as a relatively versatile and workstation-friendly G34 platform.<br /> <br /> Ports of [[coreboot]] and [[OpenBMC]] to the D16 were initially developed by [[Raptor Engineering]] between 2015 and 2017. Among major coreboot versions, it was first supported in coreboot 4.2 in October 2015, and last supported in coreboot 4.11 in November 2019. The port was never completed and was removed in coreboot 4.12 due to lack of maintenance. Between 2021 and 2022, after seeking funding for such an effort for several years, [[3mdeb]] developed an out-of-tree fork of coreboot 4.15 for the board under their Dasharo brand. The effort to complete and re-upstream the [[Raptor Engineering|Raptor]] port was unsuccessful and officially abandoned in August 2025&lt;ref&gt;https://github.com/Dasharo/dasharo-issues/issues/478&lt;/ref&gt;.<br /> <br /> An independent port of [[coreboot]] to the D16, using AMD's open source AGESA and CIMx codebases, was released in October 2025 by 15h.org. It is currently the most complete and only actively developed port of [[coreboot]] for the KGPE-D16.<br /> <br /> == Open Source Firmware ==<br /> Open source firmware for the KGPE-D16 is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization. The git repository for the firmware can be reviewed [https://git.15h.org/mrothfuss/coreboot-15h here].<br /> <br /> === coreboot-15h ===<br /> {{Excerpt|Coreboot-15h|[[ASUS KGPE-D16]]|hat=no|bold=1}}<br /> <br /> === Display Output ===<br /> [[File:KGPE-D16 VGA Jumper.png|frameless|400x400px]]<br /> <br /> The mainboard VGA_SW1 jumper determines whether the onboard VGA ([[ASPEED AST2050|AST2050]]) or a PCIe GPU will be used as the bootup display. Set VGA_SW1 to &quot;Enable&quot; to use the onboard VGA. Set VGA_SW1 to &quot;Disable&quot; to use a PCIe GPU. Once your OS has booted, drivers for any GPU of your choice can be used to setup a display. For blob-free opertions, it is recommended to use the onboard VGA in textmode for the bootup display but then switch to a FOSS driver (ie: amdgpu) for the user interface.<br /> <br /> ==== Onboard VGA Output ====<br /> The onboard VGA, [[ASPEED AST2050|AST2050]], can be setup with a closed-source VGABIOS (full VGA support) or with an open-source coreboot driver (textmode VGA support). A compatible display, generally an old VGA monitor, will be required to use the open-source driver. The closed-source VGABIOS is only included in coreboot-15h release ROMs with the &quot;VGA-OpROMs&quot; tag.<br /> <br /> ==== PCIe GPU Output ====<br /> To use a PCIe GPU as the bootup display, PCIe Option ROMs must be executed by SeaBIOS. This is enabled in 15h.org release ROMs with the &quot;VGA-OpROMs&quot; tag. The relevant coreboot-15h menuconfig option for SeaBIOS is &quot;Payload &gt; Execute PCIe Option ROMs&quot;. The &quot;VGA Only&quot; option is the recommended setting when using a PCIe GPU as the bootup display.<br /> <br /> === Fan Output ===<br /> [[File:KGPE-D16 Fan Jumper.png|frameless|400x400px]]<br /> <br /> The [[coreboot-15h]] release ROMs for KGPE-D16 are configured to adjust fan speeds based on temperatures measured at the CPUs and the Northbridge. The KGPE-D16 has two fan zones: one for CPU fans (CPUFAN_SEL1) and one for chassis fans (CHAFAN_SEL1). These can be assigned to either 4-pin (PWM regulated) or 3-pin (Voltage regulated) fan control outputs. The 4-pin (PWM regulation) mode offers better control over fan speeds and is the recommended setting for both fan zones. It is important to not use a 4-pin fan in a zone configured for 3-pin control; the fan will receive both voltage regulation and PWM regulation, causing irregular fan speeds. For quiet 3-pin chassis fans, it is recommended to leave the CHAFAN_SEL1 set to 4-pin (PWM regulation) mode. This will let the 3-pin chassis fans operate at 100% speed regardless of thermal readings.<br /> <br /> === Missing Features ===<br /> * The two black SATA ports are inactive.<br /> * S3 Suspend/Resume is unsupported.<br /> * Opteron 6100 series CPUs are unsupported.<br /> * TPM support is untested.<br /> * ASUS MIO audio cards are untested.<br /> <br /> === Flashing ===<br /> To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required. The DIP-8 flash chip is located at the bottom right corner of the board (labeled BIOS in the motherboard diagram). A 3.3V CH341a programmer can be used to flash coreboot onto the KGPE-D16.

Originally sold as a standalone board in a mostly-standard SSI EEB form factor, and intended for both desktop and rack-mounted uses, the KGPE-D16 is popular among enthusiasts as a relatively versatile and workstation-friendly G34 platform.<br /> <br /> Ports of [[coreboot]] and [[OpenBMC]] to the D16 were initially developed by [[Raptor Engineering]] between 2015 and 2017. Among major coreboot versions, it was first supported in coreboot 4.2 in October 2015, and last supported in coreboot 4.11 in November 2019. The port was never completed and was removed in coreboot 4.12 due to lack of maintenance. Between 2021 and 2022, after seeking funding for such an effort for several years, [[3mdeb]] developed an out-of-tree fork of coreboot 4.15 for the board under their Dasharo brand. The effort to complete and re-upstream the [[Raptor Engineering|Raptor]] port was unsuccessful and officially abandoned in August 2025&lt;ref&gt;https://github.com/Dasharo/dasharo-issues/issues/478&lt;/ref&gt;.<br /> <br /> An independent port of [[coreboot]] to the D16, using AMD's open source AGESA and CIMx codebases, was released in October 2025 by 15h.org. It is currently the most complete and only actively developed port of [[coreboot]] for the KGPE-D16.<br /> <br /> == Open Source Firmware ==<br /> Open source firmware for the KGPE-D16 is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization.

Set VGA_SW1 to &quot;Enable&quot; to use the onboard VGA. Set VGA_SW1 to &quot;Disable&quot; to use a PCIe GPU.<br /> <br /> ==== Onboard VGA Output ====<br /> The onboard VGA, [[ASPEED AST2050|AST2050]], can be setup with a closed-source VGABIOS (full VGA support) or with an open-source coreboot driver (textmode VGA support). A compatible display, generally an old VGA monitor, will be required to use the open-source driver. The closed-source VGABIOS is only included in coreboot-15h release ROMs with the &quot;VGA-OpROMs&quot; tag.<br /> <br /> ==== PCIe GPU Output ====<br /> To use a PCIe GPU as the bootup display, PCIe Option ROMs must be executed by SeaBIOS. This is enabled in 15h.org release ROMs with the &quot;VGA-OpROMs&quot; tag. The relevant coreboot-15h menuconfig option for SeaBIOS is &quot;Payload &gt; Execute PCIe Option ROMs&quot;. The &quot;VGA Only&quot; option is the recommended setting when using a PCIe GPU as the bootup display.<br /> <br /> === Fan Output ===<br /> [[File:KGPE-D16 Fan Jumper.png|frameless|400x400px]]<br /> <br /> The [[coreboot-15h]] release ROMs for KGPE-D16 are configured to adjust fan speeds based on temperatures measured at the CPUs and the Northbridge. The KGPE-D16 has two fan zones: one for CPU fans (CPUFAN_SEL1) and one for chassis fans (CHAFAN_SEL1). These can be assigned to either 4-pin (PWM regulated) or 3-pin (Voltage regulated) fan control outputs. The 4-pin (PWM regulation) mode offers better control over fan speeds and is the recommended setting for both fan zones. It is important to not use a 4-pin fan in a zone configured for 3-pin control; the fan will receive both voltage regulation and PWM regulation, causing irregular fan speeds. For quiet 3-pin chassis fans, it is recommended to leave the CHAFAN_SEL1 set to 4-pin (PWM regulation) mode. This will let the 3-pin chassis fans operate at 100% speed regardless of thermal readings.<br /> <br /> === Missing Features ===<br /> * The two black SATA ports are inactive.<br /> * S3 Suspend/Resume is unsupported.<br /> * Opteron 6100 series CPUs are unsupported.<br /> * TPM support is untested.<br /> * ASUS MIO audio cards are untested.<br /> <br /> === Flashing ===<br /> To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required. The DIP-8 flash chip is located at the bottom right corner of the board (labeled BIOS in the motherboard diagram). A 3.3V CH341a programmer can be used to flash coreboot onto the KGPE-D16.

The differences between the four revisions have not been disclosed. The more recent boards (1.04 and 1.05) are generally in better condition and are recommended. Board revisions 1.03G, 1.04, and 1.05 are known to perform equally well when in similar condition. No community members have tested a 1.02G revision board. The KGPE-D16 can be found rebranded for distribution in China (KGPE-D16/CHN). The CHN variant can also run coreboot like the other KGPE-D16 variants, there are no known differences.<br /> <br /> == Board View ==<br /> Board views are available for the KGPE-D16.

This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.

This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2. Building on FreeBSD is the same as building on Linux, but 'make' is replaced with 'gmake'.<br /> <br /> '''Tested GCC Versions'''<br /> * GCC12 Works<br /> * GCC14 Fails, run-time errors.<br /> * GCC15 Fails, compile-time errors.<br /> <br /> '''Debian 12 Dependencies'''<br /> <br /> &lt;nowiki&gt;<br /> apt install git build-essential m4 bison flex zlib1g-dev libncurses-dev imagemagick python-is-python3 gnat libssl-dev pkg-config<br /> &lt;/nowiki&gt;<br /> <br /> '''FreeBSD 14.2 Dependencies'''<br /> <br /> &lt;nowiki&gt;<br /> ### This list may be incomplete<br /> pkg install git bash gmake gcc12 m4 bison ImageMagick7 python autoconf automake gettext-tools gnu-unifont<br /> &lt;/nowiki&gt;<br /> <br /> '''Configuring and Compiling'''<br /> <br /> &lt;nowiki&gt;<br /> ### Fetch coreboot-15h source<br /> # Tip: Add the '--depth=1' argument to save bandwidth.

This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.<br /> <br /> == History ==<br /> <br /> Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase&lt;ref&gt;https://github.com/mrothfuss/coreboot-D16 coreboot-D16&lt;/ref&gt; and development by [[Dasharo]] to migrate the platform to coreboot 4.15&lt;ref&gt;https://docs.dasharo.com/variants/asus_kgpe_d16/overview/&lt;/ref&gt;. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork&lt;ref&gt;https://github.com/Dasharo/coreboot/pull/116&lt;/ref&gt;. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.<br /> <br /> Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.<br /> <br /> In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.<br /> <br /> == Compiling coreboot from source ==<br /> Compilation has been tested on Debian 12 and FreeBSD 14.2.
