That is a very neat project :-) It can also be expanded to something not just the VESA driver will use, but as a general interface whenever the BIOS services are to be needed. I can already think several uses for it (warmboot secondary cards, save/restore current video state, disable/enable the display, DDC/EDID, etc). I will be very interested if that project is revived. BTW: I want to initialize multiple VGA adapters during the early boot sequence. The machine will be in real mode, so there's no such thing as copy-on-write. I'm pretty sure it's not possible, but do you know of a way to disable the BIOS write protection of the C000:0000 segment?
