Under Power Management Setup, make sure that "PM Control By APM" is set to "Disabled" (if available). Under PNP/PCI Configuration, make sure that "PNP OS Installed is Set to "Yes".

Currently Intel has changed the configuration of their 1 gig heat sink and fan combination. This heat sink and fan combo currently will not fit correctly on any TYAN motherboard. If you have this problem we suggest you use a heat sink and fan combo from Alpha Nova Tech. The part number is PAL 6035. This combination has been tested and found to fit in all the current TYAN layout designs. Why can't I get my 1 GHz (or higher) Celeron to work with my P3 based motherboard? Starting in January of 2001 Intel added a 256k Cache Celeron to the market place. These celeron cpu's start at 1ghz and go up to 1.3 ghz. These cpu's can be identified as 1 A GHz/100 cpus or by the term FC-PGA2. These cpu's are not compatible for the P3 line of motherboards from TYAN. The serial numbers can be read directly on the cpu's themselves to determine if they are able to run on our P3 line of motherboards. The serial numbers included in this incompatible list are: SL5ZF,SL5VP,SL5XU,SL5XR,SL5VQ,SL5ZE,SL5XS,Sh5Y5,SL656,SL5VR,SL5ZJ
