I don't think the CGA/MDA/VGA graphics memory areas should be executable, and I doubt execute access to these areas is required - is it?
0xA000:0000 might be a BIOS area, if it is, you don't have a VGA and the ROM will be exactly 64K. 0xB800 and 0xB000 SHOULD NOT be a ROM, nobody dared to use it (I don't remember exactly where ROMs are searched). -- Funny quotes: 34. If FedEx and UPS were to merge, would they call it Fed UP?
