AH = function 00h install and initialize BIOS subsystem AL = ??? (00h,01h,03h) CX:BX = subsystem ID (see #03971) ESI = address from which to load, or 00000000h for default for subsystem EDI = physical address at which to install, or 0 for default
Note: If CX=0000h on entry, this call is applied to all subsystems whose ID has low word BX 01h get BIOS subsystem information CX:BX = subsystem ID (see #03971)
Return:
AL = ??? AH = ??? EDX = uncompressed size of subsystem in bytes SI = offset within subsystem of initialization routine, or FFFFh if none EDI = physical address of default location or 0 02h get matching subsystem identifier AL = index into subsystem list (return ALth occurrence matching BX) BX = low word of subsystem identifier (0001h,0002h,0004h,0005h,000Bh,FFFFh)Return:
CF clear if successful CX = high word of ALth matching subsystem CF set on error
Note: The system is halted if AL=00h on entry 03h set up "big real" mode (4G segment limits) 04h turn off "big real" mode (restore 64K segment limits) 05h remove BIOS subsystem CX:BX = subsystem ID to leave out
Note: The system is halted if an invalid (not installed) subsystem ID is specified 06h get installed subsystem info CX:BX = subsystem ID (see #03971)
Return:
CF clear EDX = length of ??? EDI = linear address of start of ???
Note:
The system is halted if an invalid (not installed)
subsystem ID is specified
Return:
CF clear if successful CF set on non-fatal error
Note: This interrupt vector is cleared to 0000h:0000h near the end of the BIOS startup sequence
