4.1.2.1 CPU Configuration
The CPU Configuration setup screen varies depending on the installed processor.
4.1.2.1.1 Max CPUID Value Limit
The Intel® Processor Identification Utility requires the 'Max CPUID Value Limit' in the
system BIOS to be disabled for proper processor identification. Once processor
identification has taken place, the option can be re-enabled if desired.
4.1.2.1.2 Vanderpool Technology
Vanderpool Technology allows a platform to run multiple operating systems and
applications in independent partitions. With VT, one computer system can function as
multiple “virtual” systems.
Note: After any change to this option, system must be powered off to take effect.
4.1.2.1.3 Execute Disable Bit
A feature designed to stop buffer overflow attacks against the operating system. Buffer
overflow attacks are one of the most common tactics used to attack personal computers.
The processor prevents the execution of code in data-only memory pages while enabled
and will not restrict code execution in any memory area if disabled. This makes the
processor more vulnerable to buffer overflow attacks
