INT 15 U - AMIAmerican Megatrends, Inc.(American Megatrends, Inc.) A hardware, software and firmware company founded in 1985. 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. - Flash ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. - GET 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. REVISION AX = DB04h Return: CF clear if supported BL:BH:DL:DH = 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. revision string (e.g. 'AX1 ' for v1.00.05.AX1, 'AV0M' for v1.00.03.AV0M) CL = flag: DH valid? 00h ignore DH; ignore DL as well if 20h (space) 01h ignore DH if 20h (space) CH = BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.
