INT 10,1C - Save/Restore Video State (VGA only)

AH = 1C

% AL = 0 get save buffer size

CX = requested states

bit 0: video hardware state

bit 1: video BIOS data areas

bit 2: video DAC state

on return:

AL = 1C

BX = buffer size in 64 byte blocks

% AL = 1 save requested state

CX = requested states (see AL = 0)

ES:BX = pointer to buffer

returns nothing

% AL = 2 restore requested states

CX = requested states (see AL = 0)

ES:BX = pointer to buffer

returns nothing
