Why can't you just write a small batch program that

room on a 360K, then you can use a second floppy. We used to do this for
customers all the time, 15 years ago. Also included small start up menus,
etc.
Drivers = extension rom code? Interesting proposition. I'll wager it's not very
straitforward. Numerous graphics cards had drivers for say Autocad and whatnot. But
that's entirely different from the startup code needed to set up initial register
values and whatever on the cards chips.
It seems what you're saying is the pc will startup w/o video (usually returns an
error, but you can use a pc w/a terminal off the rs232 port, just don't ask me the
particulars). Then initialize the video card as dos is starting. Seems possible, would be
interesting to see someone do it.

I was told by David Both that he used the very first PC off the assembly
line to write the PC Documentation. When I asked what happened to PC #1
after he was done with it he said as far as he knew the same thing they did
to all their internal use machines at the time. Stripped it for parts for
warranty repairs.

So I guess I have to find an original IBM CGA
card then and all is well?

I believe your VGA problem has to do with the older IBM ROMs, I
believe you need the '82 BIOS to use a VGA card or any card with it's
own BIOS, and being as I have a 16-64 KB 5150 with the newer BIOS I
assume yours will work also, saying you have an EPROM programmer.
