[coreboot] Problems with VIA EPIA-ME6000

[Klaus Stammermann]

Hi there

I have some trouble to use coreboot on my VIA EPIA-ME6000 so I hope someone 
could give me some hints. 

With epia-m and filo I can build a bios without vga. This runs till jumping to 
kernel. This breaks up with an error:
Loading kernel... ok
"Jumping to entry point...
0

coreboot-2.0.0.0-Fallback Mo 18. Feb 16:59:57 CET 2008 starting..."

I tried with a PCI-VGA-card, "option CONFIG_CONSOLE_VGA = 1" and "option 
CONFIG_PCI_ROM_RUN=1".  This breaks up with this error:

"INSTALL REAL-MODE IDT
DO THE VGA BIOS
found VGA: vid=102b, did=519
rom base, size: fffc0000
write_protect_vgabios
bus/devfn = 0xa0
Unexpected Exception: 13 @ 10:00013808 - Halting

edi: 0001a4b0 esi: 00024a70 ebp: 00023f54 esp: 00023f54"

And using VGA-support with onboard device I get this message:
"DO THE VGA BIOS
found VGA: vid=1106, did=3122
rom base, size: fffc0000
BAD SIGNATURE 0x7f 0x45

What do I have to do to boot with a VGA-card? Are there any options which have 
to be set?

Else, using onboard vga device I got the vga-bios by PERL-script 
(www.coreboot.org/VGA_support). Is it right this vga bios has to be insert in 
front of coreboot image? Should it be 64k big or just as big as it is in 
original? And on which adresses the parts of vga-bios, normal and fallback 
(with there payload) have to be set?

Does anyone use this board with coreboot too? Could some show a Config-file 
for this so I may see my mistakes?
