John: I have placed P6 series processors (Celeron 366s oc'ed to 550) in motherboards without a fan and with the bios overheat protection disabled. They would run for about a minute and crash. After a 5 minute cool down, they would be fine. Same exact thing happens with AMD 486, K6 and K6-2 chips (I haven't tried any K5s), as well as my Athlon Classic. I believe that the catastrophic shutdown has been a feature of Intel processors ever since the Pentium MMX, although it has not been documented as such. Well, I'm not at all convinced, but anyway... it wasn't really needed before TBird and P4. There it is needed and only the P4 has it. Relying on software (bios) for catastrophic protection seems too risky. I agree completely. I'm not at all convinced that BIOS has time to kick in, if a system is booted without HS/F. -fyo
