Last time I checked Cyrix's web site, the fastest I saw was the 6x86 P150+. However, it does support the Pentium 133 & 166. You might want to flash the bios to the latest version. If that doesn't work you might want to drop the speed to P150+ and see if the problems go away. ---- || Shoppers Network BEST PRICES, FULLY x86 COMPATIBLE & FAST!!! || PO BOX 16627 Cyrix 686s now available! || San Francisco, CA 94116 Email - info@shoppersnet.com | ------------------------------> WWW - http://www2.shoppersnet.com -------------------------------> WWW - http://www.shoppersnet.com/shopping
