Delay Prior to Thermal
Some Intel processors have a function called Thermal Control Circuit (TCC) to
prevent overheating of the CPU. When TCC is activated, the CPU idles about 50-
70% of the time to cool down the processor. During bootup, the CPU will
typically heat up during heavy load, and it is not desired to trigger the TCC too
early because it will reduce performance. Settings are 4, 8, 16, and 32 minutes.
Limit CPUID MaxVal
Intel Penitum 4 with Hyper-Threading Technology processors report a higher
CPUID than “3”. Older operating systems are not able to recognize this, so this
setting should be enabled if using such OS.
Execute Disable Bit
When enabled, this feature protects areas of memory from malicious code.
