Limit CPUID Max imum
When the computer is booted up, the operating system executes the CPUID
instruction to identify the processor and its c apabilities. Before it can do so, it must
first query the processor to find out the highest input value CPUID recognizes. This
determines the kind of basic information CPUID can provide the operating system.
Options: Disabled (Default) / Enabled
Execute-Disable Bit
XD can prevent certain classes of malicious buffer overflow attacks when combined
with a supporting OS (Windows Server 2003 SP1, Windows XP SP2, SuSE Linux
9.2, RedHat Enterpris e 3 Update 3.).
Options: Enabled (Default) / Disabled
Hardware Prefetcher
The processor has a hardware prefetcher that auto matically analyzes its requirements
and prefetches data and ins tructio ns from the memory into the Level 2 c ache that are
likely to be required in the near future. This reduces the latency associated with
memory reads.
Options: Enabled (Default) / Disabled
