Thermal Management
The processor used has a thermal monitor. The profile is preset and cannot be changed.
Delay Prior to Thermal
The following options are available: 4, 8, 16 or 32 minutes. This option is only applicable for systems with 0.13µ Intel Pentium 4 processors with 512 KB L2 cache. These processors come with a thermal monitor consisting of a thermal sensor and a thermal control circuit (TCC). Once the thermal sensor detects that the processor has reached its maximum safe operating temperature, the TCC is activated and clocking is reduced to 50-70%. This parameter should be set to 4 minutes, unless the PC needs longer for booting, in which case a suitable higher value should be used.
Execute Disable bit
This setting option is only available for certain processors with Execute Disable Bit (XD bit) function. If this option is set to [Enabled] (activated), the processor can classify areas in memory by where application code can execute and where it cannot, thereby protecting your memory.
