Coreboot-fam15

coreboot-fam15 is a distribution of coreboot for AMD Family 15h hardware, developed by mrothfuss. This version of coreboot utilizes AMD's open source AGESA firmware found in coreboot-4.0. This older version of coreboot can be built by Debian 6. Recent CPU microcode updates and support for the H8DGI motherboard have been added to the codebase (https://github.com/mrothfuss/coreboot-fam15). The AGESA codebase is robust, development primarily involves adding/improving board configurations.

Board Status

Supermicro/H8DGI

Pros

• Stable with as much as 512GB of RAM (atlas)
• Has debugging output on the RS232 port

Cons

• The IOMMU has not been activated
• Secondary northbridge has not been activated, this disables 3 out of the 6 PCIe slots.
• The only active x16 PCIe slot is very close to CPU1; large CPU coolers will obstruct this slot and limit GPU support.
• No fan control or hardware monitor
• No open source BMC (the stock BMC can be disabled by a motherboard jumper)
• Blob required for onboard VGA

Supermicro/H8SCM

Pros

• Stable with as much as 128GB of RAM
• Fan control and hardware monitor are active (limited testing suggests fans only accelerate)

Cons

• No debugging output on the RS232 port
• The IOMMU has not been activated
• No open source BMC (the stock BMC can be disabled by a motherboard jumper)
• Blob required for onboard VGA

Supermicro/H8QGI

Pros

• Has debugging output on the RS232 port
• Fan control and hardware monitor are active (limited testing suggests fans only accelerate)

Cons

• The IOMMU has not been activated
• No open source BMC (the stock BMC can be disabled by a motherboard jumper)
• Blob required for onboard VGA
• Minimally tested

ASUS/KGPE-D16 and ASUS/KCMA-D8

• Initial ports for these boards have been added (develop branch)
• The boards boot and have debugging output on the RS232 port
• The KGPE-D16 passes raminit and executes a coreboot payload
• No video output yet, it is unknown if these ports can actually boot an OS.
