This paragraph is a little confused.  Let me try to clear this up:
you CAN change video modes.  You simply cannot go into the *extended*
super-VGA modes.  That is, when you are running in a Windows DOS session,
your card acts like a normal IBM VGA.  The problem with locking up is
most likely because whoever wrote the drivers for those programs isn't
bothering to check whether the video card can do the extended modes or
not.

As I've said before, you can get around this by using the V7VGA utility
provided with the card.  Type "V7VGA pure:off" and you'll be able to use
all the extended modes.  However, this may open up a whole other can of
worms, especially if you start switching between DOS sessions or back to
windows.  Just remember, extended modes are not supported in Windows DOS
sessions, and you may run into to problems.
