[coreboot] Qemu and SeaBios.

2009-11-17 Thread Knut Kujat 
Hi,
since I want to use SeaBios on my real MoBo I wanted to try it out first
using Qemu so I compiled coreboot v2 with the emulation MoBo and using
the latest seabios-0.4.2. Now the problem is that qemu is booting all
the time without getting seabios fully loaded:

-->> reboots

Now I'm concerned that this could be happening on the real board,too. I
already tried to compile seabios from the source same result.
I tried to use it with a linux.img to see if it boots but nothing! I'm
having the same problem with the "ready to use" coreboot v2 + SeaBios
from the coreboot wiki.

any suggestions? I have a coreboot + seabios compiled and ready to flash
it to the real board but I'm now scared like hell it just will boot and
boot.

thx,

Knut Kujat

Last time I checked, some versions of qemu don't allow the f segment (BIOS
area) to be written.  I use 0.9.1 (included with my Ubuntu distribution.)

I'm not sure that that's your problem, but it's a likely candidate.

Thanks,
Myles
