Coreboot Now Supports Another Dual-Socket AMD Motherboard

The latest motherboard being supported by Coreboot for replacing the board's proprietary BIOS is the ASUS KFSN4-DRE.

The ASUS KFSN4-DRE is a dual-socket AMD Opteron (1207F) motherboard powered by the NVIDIA nForce4 Professional 2200 chipset. This is far from being a new motherboard, but at least it's yet another one finally being freed thanks to Coreboot.

The Coreboot support with the KFSN4-DRE has been tested with Ubuntu 14.04 with all peripherals seeming to work in conjunction with AMD Opteron 8347 and also Opteron 8356 CPUs. AMD PowerNow functions are working correctly with Coreboot via ACPI too.

On the downside, suspend/resume functions at S1 but sometimes hangs on resume, Wake-On-LAN is flaky, and the XGI Volari graphics option ROM crashes with SeaBIOS but later recovers after Linux boots and initializes the XGI graphics.

Those that happen to have one of these ASUS server motherboards around can find out more details about this new port via this Git commit.
