Hello,

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.

I have no experience with any of this, but I was thinking if I wanted to attempt something similar would probably take a look at some of the free open source BIOS replacements like: https://www.coreboot.org/

I’d look for the sections of code that initialize the video bios and copy the video rom to system ram.

Check out DOSBox Distro:

a lightweight Linux distro (tinycore) which boots off a usb flash drive and goes straight to DOSBox.

Make your dos retrogaming experience portable!
