AH = 00
AL = 00 40x25 B/W text (CGA,EGA,MCGA,VGA)
= 01 40x25 16 color text (CGA,EGA,MCGA,VGA)
= 02 80x25 16 shades of gray text (CGA,EGA,MCGA,VGA)
= 03 80x25 16 color text (CGA,EGA,MCGA,VGA)
= 04 320x200 4 color graphics (CGA,EGA,MCGA,VGA)
= 05 320x200 4 color graphics (CGA,EGA,MCGA,VGA)
= 06 640x200 B/W graphics (CGA,EGA,MCGA,VGA)
= 07 80x25 Monochrome text (MDA,HERC,EGA,VGA)
= 08 160x200 16 color graphics (PCjr)
