Quick question. Have you tested that you absolutely have to do this: Edit src/mainboard/rca/rm4100/Config.lb and comment out these lines so it looks like this:
# chip drivers/pci/onboard # Onboard VGA device pci 2.0 on end # VGA (Intel 82830 CGC) # register "rom_address" = "0xfff00000" # end
i.e. did you just try all the other mods without doing this? I realize 2.0 is on its way out in the next year, but having to modify this file says something is very, very wrong.
thanks
