Compatibility: 5.0+

Expects: AX    b000H

Returns: AL    status: 00H = GRAFTABL.COM is not installed

ffH = GRAFTABL.COM is installed

Info: Checks to see if the DOS 5.0+ GRAFTABL.COM program has been

executed and its graphics-character definitions have been made

resident.

GRAFTABL.COM installs data that defines how ASCII characters 80H-

ffH are displayed while in graphics mode (see Video Modes).  It

loads about 1K of data into memory and modifies the INT 1fH

vector to point to that data.

GRAFTABL.COM is used only by CGA owners, and even then, very

rarely.
