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. Recent CPU microcode updates and support for the H8DGI motherboard have been added to the codebase (https://github.com/mrothfuss/coreboot-fam15).
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/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
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
ASUS/KGPE-D16 and ASUS/KCMA-D8
- Initial ports for these boards have been added (develop branch)
- The boards boot and have debuggin 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.
