The following patch is the cause of the dirty flag on status reports; no other changes are made to the source.  This patch specifically allows the test stand to recover from a bad build that transfers control from coreboot properly but subsequently fails to boot Linux, and will never be merged to master.
This board is automatically tested by Raptor Engineering's test stand.  For more details please visit [[AutoTest/RaptorEngineering]].

ASUS KFSN4-DRE PCB 1.04G at Raptor Engineering.

General Information

The KFSN4-DRE is a relatively modern AMD K8 / Family 10h motherboard. It is well supported and stable under Coreboot with Family 10h processors, with all CPUs, RAM, and peripherals functioning normally. K8 processors currently require specific RAM configurations to work correctly.

This board is automatically tested by Raptor Engineering's test stand. For more details please visit AutoTest/RaptorEngineering.

Installation Notes

  • coreboot can be flashed internally when migrating from the proprietary BIOS. Flashrom can safely reprogram the ROM under Linux.
  • When migrating from the proprietary BIOS, after flashing coreboot the CMOS memory should be cleared. Failing to clear the CMOS could result in odd hangs during the boot process.

Known Issues

It has recently come to my attention that booting from USB mass storage devices is not possible. Both SeaBIOS and GRUB fail to see any attached flash drives, even though the USB keyboard functions normally. Also, grub is unable to properly initialize the USB keyboard (very slow typing rate, several seconds per character), but SeaBIOS functions normally. Additional debugging is needed by an interested party to resolve these issues. Tpearson (talk)
