I just checked out a fresh new version (2100) of LinuxBiosV2. Epia-M
builds (default-config) and boots with VGA.
The VGA Bios has to be extracted like Jun said:
# dd if=/dev/mem of=video.bios.bin.4 bs=1 count=65536
786432 is 0xc0000, and 790528 which Nich told is 0xc1000.
I haven't tried X yet.
Nice work and thank you all for your help.
