Does anyone
know if any of the more modern (ie: VGA) cards support
enhanced
132 column text modes?
I think this is a "maybe". At [
http://www.columbia.edu/~em36/wpdos/textmode.html ], there's a link to a
program that scans for a series of 132-column VESA text modes. It couldn't
find any on the laptop I tried it on (no surprise), but apparently there are
a number of NVIDIA cards that support these modes. I don't know what how
the layout compares to the character/attribute pairs for 80-column modes,
but here's the Pascal code they use to try entering the modes:

New subject: Need an H-37...
I'm in need of an H-37 soft-sectored floppy controller for an H-89.
I also have a need for four 720k 3.5" floppy drives that have drive select
jumpers on them. Would older Amiga drives work for this?

For my ATI cards mode 35 (23h) seems to work on most of them.
IIRC, there is also a byte in BIOS data segment 40h that identifies how
many characters per line, and another for number of lines.
MANY programs are so hard-wired to expect 80 x 25 at B000h or B800h, that
they border on unusable when you have any different configuration.

Depends on the software...
I started out with mono, never bothered doing much with CGA as the quality of
those monitors was just too poor to read much text on. With EGA and VGA I
always tried to put as much text on the screen as I could, which in practice
meant 43 or 50-line mode. [OT]Even now, when I boot my server, I kick it
into a 132x60 line mode.[/OT]
