□
Execute Disable Bit
XD can prevent certain classes of malicious buffer overflow attacks when combined
with a supporting OS.
Choices: Enabled , Disabled.
□
Intel Virtualization Technology
Virtualization Technology can virtually separate system resource into several parts,
thus enhance the performance when running virtual machines or multi interface
systems.
Choices: Enabled , Disabled.
□
Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its
requirements and prefetches data and instructions from the memory into the Level 2
cache that are likely to be required in the near future. This reduces the latency
associated with memory reads.
Choices: Enabled , Disabled.
