The reasons I'd want to do this are very odd and don't actually have anything to do with using a PC as a PC, so bear with me. 😉
What I'm trying to do is this: For the Apple ][ line there is an emulator card with pretty much a full XT on board, and I'm wondering if I can use the CGA without using the XT, since apparently the CGA registers and the 8086 memory are addressable from the 6502 side.
So as to not require setting up the V30 environment, I wouldn't have BIOS available to me, and would have to set up the CGA entirely from the 6502, by accessing the CGA ports from the 6502 side.
