It's totally straightforward, if you have proper documentation. The
VGA BIOS, also, is just code in ROM that the CPU executes. It is
called from the system BIOS at an appropriate time. VGA is only made
complex by the fact that PC BIOS and software assume certain specific
capabilities of the graphics card.
Does the PC BIOS expect anything *besides* 80x25 text mode? What's the
minimal set of expectations the PC BIOS has of the graphics card?
Let me guess: it's not standard, right? ;) I'm thinking of PC BIOSes
that give a splash screen during POST, for instance.
What's a reasonable minimum, then?
