Most of my best dos software requires vesa. Your link was extremely good.
I wish it was in a nice text book that I could sit down and read.
Not very much into windows stuff even if it is better.
I miss the vic 20 where I could poke into the video and make it
look like anything I wanted. Question could I deliver a vesa
command to the video card using the dos copy command.
Works for printers why not video. Never new the proper hex
commands so I never tried it. Might also work for cds.
Copy a simple hex file to a cd and make it play music.
Never know until you try. Might work or might not.
With the vesa commands I could change screen
resolution on my laptop and make it fill the screen.
Would have to also change the font size so I cold read it.


cheers
DS
