Hi.
The VIA EPIA BIOS is an Award/Phoenix Award BIOS, so it contains lh5/lha compressed modules. With a hex editor and/or lha/lh5 unpacker you can extract the VGABIOS from the VIA EPIA BIOS file.
Using "CBROM"/"CBROM32"/"Award BIOS Editor"/..., you can see that the BIOS file contains following BIOS modules:
CBROM32 V1.45 [08/03/04 Release] (C)Phoenix Technologies 2001-2004

If you should use "CBROM", then just use following command to extract the VGA BIOS:
"CBROM i0100113.bin /VGA extract"
PS: ... the VIA EPIA has a nice BIOS logo. ;)

I've downloaded the 1.13 version of the Epia Via BIOS, which should solve my VGA issues. Thing is, I can't seem to find a valid VGA BIOS within this file -- Is there a magic trick to extracting this?
Bios file: http://www.via.com.tw/download/mainboards/1/0/i0100113.bin
Okay,
I tried awardeco, and it DOES NOT list the VGA ROM, but CBROM (under the "dosbox" emulator) worked well.
Only one thing -- the extracted VGA ROM is _exactly_ 64000 bytes (instead of 65536) -- do I need to pad it out (with zeros?) before concatenating it with LinuxBIOS to achieve the final burnable image?

Please keep track of your procedure, what tools worked and didn't work, where you got them from, etc so we can put it on the wiki.

Yes. dd can snap it to the right size for you. You could also tweak your ROM_SIZE to make it match.

I've done a LOT of things, but they mostly didn't work =)
When this is all over, I'll write up a set of instructions, and follow them from a clean install to see if I've got it all down.

I've got the VGA extracted -- I'll burn it tonight and see what happens.
Assumedly:
dd if=vga.bios.bin of=vga.bios.bin.padded bs=65536 count=1 conv=sync
