setbus : set AT bus data width for tseng based svga cards to
either 8 or 16 operation. Most useful for Windows developers using
two monitors for CodeView debugging. By default, if there is a monochrome
(or other second monitor on the AT bus, the svga card operates at only
8 bits doubling video time.

This program allows the user to tell the svga card to use 16-bit data paths
which doubles video perforamce. This improvement is nearly complete, as
verified by the PC Labs Windows Graphics benchmark test.

Some programs, such as pcANYWHERE IV and Microsoft's CV and CVW, will
only operate when the bus is in 8-bit mode.
Changing the mode within a DOS virtual session under Windows is not
sufficient to allow these programs to operate properly. SETBUS must
be executed before Windwos for these programs to function.

The source for this code was downloaded from the STB section of the
GRAHICSVENDOR forum on Compuserv. The original author is unknown.
This is offered as-is. No claims attached.
It has been tested with an Orchid Pro Designer II card, probably works with
STB's Tseng based cards, and may work with other Tseng cards.

Files in this .zip file:
setbus.c source code.
mkbus.bat creates setbus.com if you have the correct compiler
setbus.com executable downloaded from original STB file
setbus.exe executable created from MSC 6.0
readme.doc this file


The mkbus.bat file contains the commands needed to complie the program
with some (unknown to me) compiler. I simply used Microsoft C6.00a with the
command:
cl setbus

both the .com and .exe versions appear to work properly.
