Humm OK, the main point in asking the question was
coming from the stand
point that it is easy to obtain a vga rom. Most standard bios images are
just a zip file. There are tools on the web that allow one to unzip a bios
rom file and grab the rom for the graphics controller. This was an idea that
it is trivial to grab bios image. you just run 'dd' under linuxbios while
booted from pcbios. In that way you don't have to wonder what they used to
pack/compress the bios image.
what is tricky is that the vga bios usually expect to run in 16 bit mode
and with some of pc bios routines available. There's Ollie's testvga,
there's ADLO which both attemp to solve this issue.
Both my board do not boot linux bios yet.
When I get one of these board booting linuxbios then I
will be willing
to try to get VGA bios running.
