It is impossible to set a user's font table for text output in a graphics mode

[Igor]

Interruption of VGA BIOS for installation of a user's font table is not fulfilled. The standard system call is used:

Int 10H [EGA] [MCGA] [VGA] Function 11H (17) Subfunction 21H (33) Set Int 43H for user's font

Call with:

AH = 11H AL = 21H BL = character rows specifier

00H if user specified (see register DL) 01H = 14 (0EH) rows 02H = 25 (19H) rows 03H = 43 (2BH) rows

CX = points (bytes per character) DL = character rows per screen (if BL = 00H) ES:BP = segment:offset of user font table

Returns:

Nothing

Notes:

• This function provides font selection in graphics (all-points-addressable) display modes.
