800x600 VGA Mode with AT&T Simul-Task 386--HOW???

[joel m. cook]

I have an AT&T 6386-20 running SVR3.2.1 and Simul-Task 386 2.0
with an AT&T VGA600 graphics adapter.  I have a piece of software
(DesignCAD 3-D) that can use a Paradise VGA in its 800x600 mode
and does so if I run native MSDOS.  However, if I try to duplicate
that under Simul-Task, it doesn't do it.  It will run under the
640x480 mode, however.

So my question is why?  Is there anything that I can do to get
the same results under Simul-Task?  Something in the vpix.cnf
file or somewhere else?  Any help will be most appreciated!
Thanks in advance etc...
