INT 10H 4f02H - Set SuperVGA Video Mode
Expects: AX 4f02H
BX VESA/SVGA Video Mode number (may also be std modes 00-13H)
(bit 15 set = don't clear video memory on mode set)
──────────────────────────────────────────────────────────────────
Returns: AX VESA status: AH=0 means successful (else failed)
AL=4fH means function supported
──────────────────────────────────────────────────────────────────
Info: Initializes the display adaptor for a specified video mode.
You can use this call to initialize for non-VESA mode numbers
(e.g., VGA modes 10H-13H) just by setting the mode number in BL
and clearing BH.
By default, this call clears all video memory to spaces or black
pixels. You can request to leave the video memory buffer as is
by setting bit 15 of BX.
Use INT 10H 4f00H to see what mode numbers are valid for BX.
