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.
