Virtualization Technology (VT-x)
This is used to support the visualization of platform hardware and several software
environments. Based on Virtual Machine Extensions (VMX) to support the use of several
software environments using virtual computers. Virtualization technology extends the
processor support for virtualization purposes with the 16 Bit and 32 Bit protected modes
and with the Intel® Extended Memory 64 Technology (EM64T) mode.
Disabled
A Virtual Machine Monitor (VMM) cannot use the additional hardware features.
Enabled
A VMM can use the additional hardware features.
Virtualization Technology (Intel VT-d)
VT-d is a hardware support for the common use of I/O devices by several virtual
machines. VMM systems (Virtual Machine Monitor) can use VT-d to manage several
virtual machines which access the same I/O devices.
Disabled VT-d is disabled and is not available for VMMs.
Enabled VT-d is available.
NX Memory Protection
De fi nes the protection for executable memory areas (anti-virus protection). The function
is only effective if it is also supported by the operating system.
Enabled
Enables the operating system to switch on the function "Execute Disable".
Disabled
Prevents the operating system from being able to switch on the function "Execute
Disable".
Adjacent Cache Line Prefetch
This is available if the processor offers a mechanism for loading an additional adjacent
64Byte "Cache Line" during every cache request of the processor.
Enabled
The processor loads the requested cache line and the adjacent cache line.
Disabled
The processor loads the requested cache line.
Hardware Prefetch
Enables a prefetch to the hardware.
With this option you can change the performance settings for non-standard
applications. Fujitsu Technology Solutions recommends that, for standard
applications, you should not deviate from the default settings.
Enabled
Activates the hardware prefetcher of the CPU.
Disabled
Deactivates the hardware prefetcher of the CPU.
