[Qemu-devel] Visual Basic Application Not Working Under Qemu/Win98SE/Linux

I've got a Visual Basic Application that gives an error ("invalid
property value") running under Windows 98SE under qemu under Debian
GNU/Linux sid, but the same application works fine with bochs (I'd much
prefer to use qemu for performance).

Just to make sure it wasn't something wrong with my installation disk
image from bochs, I did a whole new Windows 98SE installation with qemu,
which went fine.  I then installed the VB program and got the same error.

Is there any way I could troubleshoot this?  How could it be that Win98SE
installs fine but then a particular (simple) application won't work,
while it does work under other VMs?  The application doesn't use any
special devices (e.g., serial port)--it's just a quiz program.  

Everything else appears to work normally in the qemu/Win98SE environment.

Are there any settings I could change to try to get this application to
work?  

Thanks for any suggestions.

Perhaps is VB interpreter using some x86 instruction that
is "faulty" under Qemu (when I say "faulty", I mean there
are some discrepancies between the various x86, cf. the
problems some dynamic translators had with P4 bit fields
instructions).

Do you use the CVS version? If not, try it. There was a bug which
prevented Java to run, which has been fixed in CVS. It could well be that
this affects Visual Basic, too.

Thanks for the suggestion.  I just rebuilt with CVS and the problem is
totally gone.  (please ignore my second message on this topic where I
thought it was related to font issue).

Unfortunately, under qemu CVS, Win98SE detected two new devices (APM and
PCI bus) and I allowed it to install them.  Now when it crashes on every
reboot just after the splash screen--the screen just goes totally black.

I can reboot in safe mode, so I did and removed the power management and
PCI bus, but it still boots into a black screen.  Looks like I might have
to reinstall from scratch unless someone has some idea how to get out of
this problem.

It turns out this black screen is actually caused by the SciTech Display
Doctor Drivers.  Are there known issues using the SciTech video driver
with qemu CVS?  That part was working fine in the last release.

Add -cirrusvga to your qemu parameters and remove the Scitech drivers, 
you don't need it anymore..

Thanks,
