Board:asus/kfsn4-dre
The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
The KFSN4-DRE is a relatively modern AMD Family 10h motherboard. It is well supported and stable under Coreboot, with all CPUs, RAM, and peripherals functioning normally.
Raptor Engineering hosts an automated test system which checks this board for proper functionality every night. Successful test results are recorded to the board status repository, while failed tests are reported to the coreboot mailing list.
| CPU | 2x Opteron 2431 (Fam10h @ 2.4GHz / 6 cores ea.) |
| RAM | 6GB DDR2-667 on Node 0 channel 1 |
| OS | Debian Jessie 64-bit, kernel 3.16.0 |
| Add-on cards | None |
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.
