Dear GT,

thank you very much for your interest in LinuxBIOS.

Can you try to leave these disabled? To get VGA console on the VIA
EPIA-M they are not required. 

CONFIG_PCI_ROM_RUN enables use of the x86emu emulator to run the VGA
option rom inside an emulator. The emulator does not work well with the
VIA VGA option rom, so we are running the option rom in vm86 mode from

The vm86 code is in src/mainboard/via/epia-m/vgabios.c

I will send you a working image offline.

I can not reproduce this error yet. Let me know what you think about
above option.

> Thank for your kindness help.

You're welcome!
