[comp.os.msdos.programmer] Is a 43-line Mode Possible in PC-DOS 3.3?

gcoen@emx.utexas.edu (Gary A. Coen) (09/09/90)

Greetings to the net.

Question:  is there a way to create a 43 line screen using PC-DOS 3.3 on 
standard PS/2 hardware (viz., Model 80, 8514 monitor, standard VGA cir-
cuitry)?  If so, is it a risky business to get into (because of side 
effects, etc.)?

Thanks to all.

As far as I know, you could code page the mode into 80x43, but DOS 3.3 would
only recognize the first 25 lines.  I'm not even sure if DOS 3.3 officially
recognizes EGA/VGA (supports the graphic modes).  I'll look for a driver for
you.

I use a Paradise VGA card in 43 line and/or 132 col mode by calling
its extended modes. IBM VGA can set these modes too. 
--BUT-- 3.3 ANSI.SYS will restrict you to 25 lines.  You need
to either get a replacement ansi, remove it or goto dos 4.0.
