Execute Bit Support

Intel's Execute Disable Bit functionality can prevent certain classes of malicious

"buffer overflow" attacks when combined with a supporting operating system.

This functionality allows the processor to classify areas in memory by where

application code can execute and where it cannot. When a malicious worm

attempts to insert code in the buffer, the processor disables code execution,

preventing damage or worm propagation.

The item allows you to enable and disable the CPU ID maximum value.

CPU and NT4.0 operating system.
