Follow-up to the above...
I swapped monitors, and the same problem occured. I swapped the TNT
card and the Voodoo3 card between systems, and the Voodoo3 card worked
in the P5A-B system, but the TNT card would not work in the P3B-F
system. Same problem..would boot fine, then the video would crash when
going into graphics mode.
I tried a PCI video card (ATI rage IIc) and it worked fine in the
P3B-F.
I switched back and forth from jumper to jumper-less mode, and it
didn't make any difference.
So, unless someone has any suggestions, it looks to me like the AGP
video is hosed on the motherboard, and it will be going back...

Oh one more little nasty of the install program, it may attempt to
install msvcrt.dll which is OLDER than what you currently have.
Some people say 98 catches it and warns you, others say it simply
overwrites. So you may want to check that too...it wouldn't cause all
your problems but may render some visual basic modules inoperative in
some programs if it is replaced by an older version. Course, you had
to know what you had to begin with.

When installing a voodoo 2 or 3 card, you need to do some preparation.
First you must delete all registry entries to any prior video card or
any other 3d accelerator. For reasons I cannot guess at, the 3dfx
crowd says the driver gets confused if ANY other video driver is on
the system. Then after the registry is fixed, delete or rename any
other video drivers in your windows and system directories, and to
whatever extent there are any signs of some in your program files
directory. I suspect this is VERY important if you had prior 3DFX
products installed.
Second, after the installation it installs a vgardt.vxd, which may or
not be compatible with your existing one on your hard drive for your
motherboard. It is an intel build. You may have to experiment here.
Lastly, the card runs HOT. To rule out any heat issues after you're
sure the card's drivers are installed correctly, open your case blow
air into it using the old house fan and directed at the video card.
If the card still locks up, you can safely rule out heat issues in
normal 2d applications for now.
For testing purposes make certain you're video bios cachable and
shadow is disabled as well in your bios. For 2d applications, its
safe to disable the irq just to rule out conflicts, but don't do 3d
with the irq disabled in the AGP version.
From your description it sure sounds like "heat" to me rather than a
driver problem, but who understands all these interactions between
drivers, heat and lockups?
For what its worth, the voodoo 3 is a total surprise to me in 2d. Its
drivers are totally stable in 98 SE and work with anything I throw at
it, from video capture to browsers, to applications, to usb printers,
to scanners. I am shocked that a company so "gaming" oriented could
have produced such stable drivers in 98 SE. I am using it with a k6-3
however not the GENUINE INTEL.
Let me know what you did, and what each troubleshooting step did or
didn't do for you.
