I have implemented the write teletype function. I currently have the
code implemented in the ROM BIOS (because I can't compile a seperate VGA
BIOS for some strange reason), I use the "other" VGA BIOS for every
function that I haven't implemented yet, so I can gradually implement
things without having to do everything at once (note that I'm currently
concentrating on textmodes only in order to see the boot process for
DOS,etc).
Does someone know what IO I have to send to the VGA controller in order
for it to do 80x25 textmode? (This is for the VGA set mode function in
order to set the 80x25 mode upon boot & for clearscreen usage).
