I skipped the cursor position registers (CRTC registers 14 and 15). You skipped the cursor shape registers (CRTC registers 10 and 11) and the start address registers (CRTC registers 12 and 13). I agree that the cursor shape registers and the start address registers may be set differently from the video mode parameter table when the register values are read in scinit(). So, I don't object skipping them when comparing register values in order to make some VGA cards work. But, these registers ARE used to set up the card, aren't they?
