Compatibility: VGA
Expects: AX    1104H
BL    font block to load (VGA: 0-7)
Returns: (none)
Info: Redefines the characters on VGA cards to use the standard 16-
scanline-high text-mode font.

This is the default font initialized by the BIOS on a mode reset
(such as DOS's Mode Co80 command).

This fn does not reprogram the CRTC or BIOS variables to make
allowances for changes in character height, etc.  Use
INT 10H 1114H to have the BIOS do that automatically.

BL specifies which of the (up to) eight tables in EGA/VGA character-
definition RAM should be affected.  See INT 10H 1103H (activate
font block).  Normally, you will use BL=0, since block 0 is
normally the active font block.
