Hi Robert,
A few more things I wanted to add.
I believe I updated the BIOS to the last version I was able to obtain from FIC.
FIC has now put their BIOS image behind a password protected FTP site so I no
longer have access to it.
I believe Version JE439 is the last version BIOS they released, and I got it
off their site a few years ago.
The BIOS itself is dated from Year 2000.
I also believe I have changed some of the BIOS settings related to AGP for this
mainboard, but it has made no difference in terms of freeze behavior.
Again, this is a strange problem considering that some NVIDIA RIVA TNT2 64
cards do work fine with the FIC VA-503+ mainboard, but the VisionTek one in
particular doesn't work well (Also, the Dell pulled one doesn't work well,
either.).
Actually, I should also add that I remember seeing an error message
that said something like this with the VisionTek RIVA TNT2 64 graphics card
right before a freeze,
"GPU crash: switching to ShadowFB instead"
What does this type of an error message mean?
I will try to obtain a kern.log file that confirms this error message.
Regards,
