Hmmm, however :D
Currently, I looked in several bios.rom images on the via website.
I recognized that the latest images from Epia-ML and Epia-M have the
same VGABIOS Name and Size. Somewhere I have read that the latest Epia-M
Bios makes trouble with LinuxBios, if you extract the VGABIOS from that
Also their was a link to an older Bios of the Epia-M (I think it is
epia-m, but I'm not sure). This bios file contains an different VGABIOS
(name and size) and now I will try this VGABIOS.
Good luck ;)
But one question, should I fill the video.image to 65536 with zero?
