Hello,

Assuming that there is no PC-bios how can I set VGA to mode13h (with default palette) ?

Because that is what I am trying to do: write my own program to a rom chip, and use it instead of the pc-bios chip on an old 286 computer.

Although there will be no pc-bios, but will there still be a VGA-bios, if yes how can it be used? How does VGA bios even get mapped to system?

What is the easiest way (or ways) to initialize and set VGA card to mode13h (320x200 resolution at 256 colors) ?

Help of experienced hardware assembly coders needed.

Thanks much in advance.
