Thanks for your information. We made a board with a new
processor(still implemented on FPGA). Assuming we can not run x86
BIOS code, we did not provide provision for video BIOS.
Does the x86 emulator is architecture dependent? If it is implemented
in C language, we do have a C compiler.
I am looking for VGA specifications, such that I can understand the
datasheet better.
The original VGA specification was published by IBM. My copy says:
68X2251
S68X-2251-0
This does NOT contain a BIOS listing. But, like all IBM documentation
it is complete although a bit terse.
There is also an EGA specification published by IBM. My copy does not
have an order number and I think it only came as a package of AT
documents. It DOES contain a BIOS listing.
I doubt that you can still purchase these, but an engineering library
should have them.
There is also VESA. The "Video BIOS Extensions" are a free download:

Or perhaps they can be of some further help.
