Hello, I've just aquired an ATI VGA Wonder card for my AT clone. Does anyone know where I can find a BGI driver for Turbo C that will let me use the 800x600x256 colour mode? Or failing a ready-written driver a specification for the BGI so I can build one? Also, most of what I'm displaying is from a 24 bit RGB bitmap. Can anyone point me towards methods for choosing a pallette of 256 colours that will yeild decent results? Thanks, Paul Lalonde Paul A.

I would like to find out similar information. I have an Orchid Prodesigner Plus
board (640x480x256, 800x600x256, 1024x768x16), and I would like to write a BGI
for it. However, with the BGI tools from Borland, all they provide is a test
BGI file without any code in it - just a framework. Since this board is basically
an enhanced VGA, it would be nice if there was source code available to the
regular VGA BGI file, and I should just be able to add to it. If anyone has
such a thing, please let me know.
Also, most of what I'm displaying is from a 24 bit RGB bitmap. Can
anyone point me towards methods for choosing a pallette of 256 colours that
will yeild decent results?
I have found that the 'fbquant' program in the Fuzzy Bitmap (available by
anonymous FTP from nl.cs.cmu.edu (128.2.222.56) in directory /usr/mlm/ftp)
is the best program for converting 24-bit files down to 256. I use it all
the time to make 256-color GIF pictures from 24-bit ray-tracer output. The
author is Michael Mauldin (mlm@cs.cmu.edu)
Thanks,

If you're looking for a BGI Driver for your wonder card, on Compuserve and many bulletin boards, there is a really good driver system by... hmm, can't remember his name, but someone wrote a full driver system for utilizing the 256 color capability. I believe the author also has a ATI VGA Wonder. If you can't find it around, I may be able to uucode it and send it too you but look around for it first. Many large BBS systems have it and I know its in the Turbo C and Turbo Pascal borland forums on compuserve. Jeff Bakke NU113738@NDSUVM1.BITNET
