Hello everyone,

I started to try and get linuxbios running on my Asus A8N-SLI board. I
got serial output working by using the sunw/ultra40 source and the
appropriate superio (IT8712F). So far so good :)

After getting the message "Unbuffered Dimms not supported on Opteron" I
simply disabled the check (src/northbridge/amd/k8/raminit.c,line 1198)
since my processor is an AMD64 X2 4400+.
Sidequestion: how could the "is_opteron()"-function in
src/northbridge/amd/k8/raminit.c,line 606 be improved so it would not
wrongly identify my kind of processor as an opteron?

Now there seems to be a problem with setting up the memory since
SOFT_RESET is being issued several times before the boot process stops
with "Jumping to LinuxBIOS.".
I would be gratefull if somebody could take a look at the attached debug
output and give me a hint on where to go from here.
