Hi there,
In my bunch of motherboards, the only one supported by Coreboot is my old Asus M2N-E with Dual-Core AMD Opteron(tm) Processor 1216 HE and 4x 2Go Ram (2@667 and 2@800).
So I tried to run it with Coreboot an Seabios but nothing happened on screen and at the end of the boot log:
Waiting for 1 CPUS to stop
And a bit sooner in boot log
