DescriptionName
Classifies memory areas on the server to specify where
application code can execute. As a result of this classification,
the processor disables code execution if a malicious worm
attempts to insert code in the buffer. This setting helps to prevent
damage, worm propagation, and certain classes of malicious
buffer overflow attacks. This can be one of the following:
• Disabled—The processor does not classify memory areas.
• Enabled—The processor classifies memory areas.
We recommend that you contact your operating system vendor
to make sure the operating system supports this feature.
Execute Disable
Whether the processor uses Intel Virtualization Technology
(VT), which allows a platform to run multiple operating systems
and applications in independent partitions. This can be one of
the following:
• Disabled—The processor does not permit virtualization.
• Enabled—The processor allows multiple operating
systems in independent partitions.
If you change this option, you must power cycle the
server before the setting takes effect.
Note
Intel Virtualization Technology
Whether the processor uses Intel Virtualization Technology for
Directed I/O (VT-d). This can be one of the following:
• Disabled—The processor does not use virtualization
technology.
• Enabled—The processor uses virtualization technology.
Intel VT for Directed IO
Whether the processor supports Intel VT-d Interrupt Remapping.
This can be one of the following:
• Disabled—The processor does not support remapping.
• Enabled—The processor uses VT-d Interrupt Remapping
as required.
Intel VT-d Interrupt Remapping
Whether the processor supports Intel VT-d Coherency. This can
be one of the following:
• Disabled—The processor does not support coherency.
• Enabled—The processor uses VT-d Coherency as
required.
