INT 10 - Cirrus Logic 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. - GET VIDEO MODE AVAILABILITY AH = 12h BL = A0h AL = video mode number (00h-7Fh) Return: AH bit 0: video mode supported BX = offset of 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. subroutine to fixup standard video parameters (call subroutine with DS:SI and ES:DI as returned by this call) DS:SI -> standard video parameters or FFFFh:FFFFh ES:DI -> supplemental video parameters or FFFFh:FFFFh SeeAlso: AH=00h,AH=12h/BL=9Ah,AH=12h/BL=A1h
