PCI settings on EPIA-ME6000

[Klaus Stammermann]

Hi there

I try to config coreboot to use it on VIA EPIA-ME6000 with onboard vga.
Therefore I changed Config.lb in src path.

Here output of lspci:

Please look at this config. Is it possible to use onboard vga with these
parameters?

Hi,

I managed to build coreboot with onboard vga for EPIA MII using epia-m
target code.
I'm still playing with one odd detail, but it works.

I'll post the config this afternoon.
