I am running a Cyrix 166 with a Biostar 8500 TUC motherboard w 32megs. The installation of this video is causing a fatal error message and or hang ups when re-booting. I was able to set display to vga and get the card installed but when I reset color settings or re-boot, the system crashes. Is it possible that this a problem with the Intools 99 software or motherboard.
