Lonnie,

	What's most likely happening is that the EGA is truly displaying
43 lines--but the software driving the screen (ANSI.SYS perhaps?) thinks there
are 25 lines.  I came across this problem when I was trying to get a 50-line
CGA display (yes, it is possible...) and discovered I had to mess with some
ROM-BIOS variables to make the BIOS routines aware of the 50-line screen.

	If you're really interested in using your EGA with 43 lines, check
out the public domain screen driver NANSI.SYS.  It claims to support
the 43-line mode (although I can't vouch for that, as I don't have an EGA).
There are other programs that do that same, such as Hersey Micro Consulting's
FANSI-CONSOLE (shareware, $75 for full registration).

	There may also be a way to tell the EGA BIOS to use 43 lines, but
I'm not aware of that.  Good luck!
