INT 2B - IBMInternational Busiuness MachinesInternational Busiuness Machines) A hardware, software and other service technology company founded in 1911. ROM-DOS v4.0 - ???
AH = function
00h ??? (modifies data in IBMBIO.COM)
01h internal operations
02h ???
AL = index (00h-0Ch)
Return: AX = ??? or (CMOS(Complementary Metal-Oxide-Semiconductor) A type of integrated circuit design known for its low power consumption. 2Dh and CMOS(Complementary Metal-Oxide-Semiconductor) A type of integrated circuit design known for its low power consumption. 2Eh)
03h get ??? data
Return: AX = (CMOS(Complementary Metal-Oxide-Semiconductor) A type of integrated circuit design known for its low power consumption. 2Dh and CMOS(Complementary Metal-Oxide-Semiconductor) A type of integrated circuit design known for its low power consumption. 2Eh)
BX = FFFFh
other does nothing
Note: function 03h is called by ROMSHELL.COM; if BX != 0, then the ES:DI from
INT 2F/AX=1982h points at valid data
