John, thanks for the info... but... The P6 family processors introduced a thermal diode that acts as a catastrophic shutdown detector. &#133 This catastrophic shutdown detector is also implemented in the Pentium 4 processor, and it is always enabled to protect the processor. That certainly sounds like the P6 has active thermal protection (and not _just_ a thermistor). However, I'm still not quite convinced that this doesn't need BIOS involvement (in which case it isn't all that much better than a thermistor placed underneath the processor, which is available on some motherboards - and for all chips). The reason I'm not fully convinced is that I can find no mention of the active portion in the PIII datasheets. The thermistor is described, but there's no mention of any active shutdown features - only that you can use the readings for "thermal management purposes". The Pentium III processor for the PGA370 socket incorporates an on-die diode that may be used to monitor the die temperature (junction temperature). A thermal sensor located on the motherboard, or a stand-alone measurement kit, may monitor the die temperature of the processor for thermal management or instrumentation purposes. Tabl e 25 and Table 26 provide the diode parameter and interface specifications. -fyo
