The problem isn't as simple as it seems, as I use EMM386 to provide UMB's, so the computer's in V86 mode (otoh, perhaps that's a good thing...). Anyway, what I would like to do is put the updated version of my video ROM (Cirrus Logic, if you must know) on top of its old location, which is shadowed by the BIOS and probably again by EMM386. Anyway, is there any way to mess with things so the code seems to be at C000:0000 (et al.) but the presumably changed interrupt vectors don't mess up non-V86 mode programs? I apologize if this message is too demanding, but I know very little about 386 protected mode--any help would be greatly appreciated. Thanks!
