If you want to pick nits, I'd have to argue that Int 5h and Int 17h are in fact part of neither MS-DOS nor PC-DOS, but rather the PC's ROM BIOS. Unless, of course, you consider the omnipresent ROM BIOS to be part of the comparatively transient DOS. Consider this: if you load some software that takes over the system (e.g., Flight Simulator et al), MS-DOS and PC-DOS don't exist in the system, but Int 5h and Int 17h are still available. bill frolik hp-pcd!bill
