Description
When enabled, memory remapping relocates memory
space (3GB - 4 GB) to the space above 4 GB.
When disabled, the Intel processors supporting the
XD feature reports the support to the operating
system.
When enabled, the Intel processors supporting the
XD feature reports the support to the operating
system. If the operating system supports this extended
paging mechanism, it will provide some protection
against software viruses that exploit buffer overflows.
Allows you to disable the VT technology in applicable
processors. If disabled, the VT feature is unusable in
any OS.
Allows you to enable the VT technology in applicable
processors.
Allows you to electrically disable the external USB
connector 1.
Allow you to electrically enable the external USB
connector 1.
Some OS, which is (NT4), fails if the value returned
in EAX is >3 when CPUID instruction is executed
with EAX=0. This setting disables the 3 or less.
Some OS, which is (NT4), fails if the value returned
in EAX is >3 when CPUID instruction is executed
with EAX=0. This setting limits CPUID function
to 3.
Disables system optimization for sequential memory
access. The processor fetches the cache line that
contains the data it currently requires.
Enables system optimization for sequential memory
access. The processor fetches the adjacent cache line
in the other half of the sector.
