INT 10 - BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. Window Extension v1.1 - GET BLANKING ATTRIBUTE AH = 12h Return: BH = attribute to use on blanked lines when scrolling Program: BWE is a TSR(Terminate and Stay Resident) A program which remains in memory after terminating in order to provide services to other programs or the user.
