VGA bios on epia-m

[ron minnich]

I'm trying to extract it. I'm wondering if anyone else has, and if so, 
where in the bios image it was? I can't see anything at an offset that 
makes lots of sense. Unless the bios copies the vga bios to ram at 0xc000, 
oh joy.

Well,
Here is the command I use.
dd if=/proc/kcore of=video.bios.bin bs=1 count=65536 skip=790528

yeah, that works on a booted system. I was looking for somethat that would 
work on a bios file, preferably on linux.

BTW Dmitry I have integrated all your changes (with some mods for things 
not done quite right) into V1 and will test tomorrow.

The EPIA-M is coming up however. Once again, once all this works, then is 
the time for the V2 port.

The last BIOS romimage format I understood compressed option roms
in a hacked up lharc format.

ah, ok, I've heard about this. OK, time to boot under normal bios and do 
it that way :-)
