VTEST.EXE, a diagnostic program

VTEST.EXE is a diagnostic program for your video display adapter system 
(graphics card and video BIOS). It uses the same methods to determine 
available Video modes as VR Composer does.  Use this small program 
to test how changes to your video system affect VR Composer (without 
having to run VRC.EXE).

Some early video BIOSes contain bugs. These bugs can crash VR Composer 
during startup.  If VR Composer does not run on your system, 
run VTEST to determine if the problem lies in your video BIOS.  If 
the video BIOS is at fault, contact your graphics card company. Usually 
they have an upgraded BIOS chip or a software BIOS which fixes the bugs. 
Often the software BIOS is also available on CompuServe, or other BBSes. 
If a fix is not available, a generic VESA software BIOS for the chipset 
on your graphics card may do the trick. They are also available from 
CompuServe and other BBSes


Using VTEST.EXE

VTEST.EXE can be run in either of two modes, normal or verbose.  When 
run in the normal mode, VTEST lists the available Video modes VR
Composer can use.

When VTEST.EXE is run in the verbose mode, it lists the steps and 
results for all the tests it makes on your video hardware.  The verbose 
mode can also report specific Video mode problems.

Usage:  To use VTEST.EXE in normal mode, just run it:

    vtest

To use VTEST.EXE in verbose mode, run it with the -v option:

    vtest -v
