DOS/32 Advanced DOS Extender - Programmer's Reference 4.05 - VBE function 4F04h - Save/Restore SuperVGA State
In: | AX = 4F04h DL = subfunction: 00h - get state buffer size Returns: EBX = number of 64-byte blocks needed 01h - save video states 02h - restore video states ECX = states to save/restore: bit 0 - SVGA hardware state bit 1 - SVGA BIOS data state bit 2 - SVGA DAC state bit 3 - SVGA state ES:EBX = pointer to save/restore buffer
Out: | AL = 4Fh (if function supported by VESA BIOS) AH = 00h (if function was successful)
Notes: a) For subfunctions 01h and 02h, the DOS Extender will internally call subfunction 00h to extract the information about size of data that is to be copied. Copyright © Supernar Systems, Ltd. 1996-2002 All Rights Reserved.
