DescriptionName
Sets the state of logical processor cores in a package. If you
disable this setting, Hyper Threading is also disabled. This can
be one of the following:
• all—Enables multi processing on all logical processor
cores.
• 1 through 10—Specifies the number of logical processor
cores that can run on the server. To disable multi
processing and have only one logical processor core
running on the server, select 1.
• Platform Default—The BIOS uses the value for this
attribute contained in the BIOS defaults for the server type
and vendor.
We recommend that you contact your operating system vendor
to make sure the operating system supports this feature.
Core Multi Processing
Classifies memory areas on the server to specify where 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.
• Platform Default—The BIOS uses the value for this
attribute contained in the BIOS defaults for the server type
and vendor.
We recommend that you contact your operating system vendor
to make sure the operating system supports this feature.

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 processorallows multiple operatingsystems
in independent partitions.
• Platform Default—The BIOS uses the value for this
attribute contained in the BIOS defaults for the server type
and vendor.
If you change this option, you must power cycle the
server before the setting takes effect.
