Is a 43-line mode possible using PC-DOS 3.3 on standard PS/2 hardware (i.e., 8514 monitor, standard VGA, Model 80-041, etc.)? If so, does anyone have a DEBUG script or some other means of accessing this mode? (I know DOS 4.x has this feature using the MODE command, but I'm reluc- tant to switch to a newer version for just this one additional feature). Many thanks to the combined wisdom of the net. --GAC

I dont think 43 line mode is possible but 50 line mode should be. (43 line mode works on EGAs, and 50 line mode works in VGAs) >If so, does anyone have a DEBUG script or some other means of accessing this >mode?

I used to have a short .com program to switch to these modes and back (real short as it just writers a value to a register.) I dont have it anymore, but there must be several programs around to do this, id guess that PCMAG has a utility somewhere......perhaps someone else has a piece of code they can post........

Yes, it is possible to put a VGA into 43-line mode. The gist of the problem is that you have to select the 8x14 character font. I have a program (in TurboC with inline assembler) that will allow you to set the VGA into a few of the rarely used configurations. Mail me if you want a copy. I'll post it if there's enough interest. The basic information was from an article by Mr. Whitney (sp?) in a recent issue of Programmer's Journal. Good luck, John Mitchell johnm@cory.Berkeley.EDU
