Does anyone know of a way of telling DOS (any version) that the screen has something other than 80 columns and 25 rows? I am trying to use the 132x43 and 80x43 modes on my VGA card, but DOS doesn't want to use the whole screen. Thanks!

I believe that you have to load a different ansi driver (assuming you have DOS's Ansi.Sys loaded). When I started using NNansi/VAnsi (came with the board)/FansiConsole the screen size problem went away. Carl Schelin tcs@mailer.jhuapl.edu

When I use different screen dimensions, Dos works fine with it. How are you changing the screen size? The referance which dos uses as the screen dimensions are the bytes in the BIOS area: 0040:004A is a word containing the screen width in columns. The word at 0040:008A contains the screen length -1 (thus 24 means 25 lines). Also, some earlier versions of dos may not use these. If so you're out of luck.

Instead it makes ASSUMPTIONS about your screen size. Some work only if you are in an 80 column mode, others just assume 80x24 period. A few peices of software (like Windows 3.0) do check, but only for IBM supported values (like if you're not in 80x25, and you are an EGA, you MUST be in 80x43.) What did I do to get around this problem the best I could? I use NNANSI as my ANSI driver. It correctly looks in the BIOS for the current screen size. It will even allow you to set certain sizes via ANSI screen codes. I also downloaded an EGA screen package from SIMTEL20 called ANSI-432.ARC. It contains a MORE.COM which also checks the BIOS for the number of lines on the screen. It is a replacement for the MORE.COM which comes with DOS. It should work with any 100% compatible BIOS. ================================================================= Kevin J.
