4-9

to be regulated via the CPU Internal Clock modulation when the CPU temperature

reaches the overheat threshold. The options are Disabled and Enabled.

Adjacent Cache Line Prefetch (Available when supported by the CPU.)

The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The

CPU fetches both cache lines for 128 bytes as comprised if set to Enabled. The

options are Disabled and Enabled.

Set Maximum Ext. CPUID=3

When set to Enabled, the Maximum Extended CPUID will be set to 3. The options

are Disabled and Enabled.

C1 Enhanced Mode (Available when supported by the CPU.)

Set to Enabled to enable the Enhanced Halt State to lower CPU voltage/frequen-

cy to prevent overheat. The options are Enabled and Disabled.

Note: Please refer to Intel’s web site for detailed information.

Intel <R> Virtualization Technology (Available when supported by the CPU.)

Select Enabled to use the feature of Virtualization Technology to allow one platform

to run multiple operating systems and applications in independent partitions, creating

multiple virtual systems in one computer. The options are Enabled and Disabled.

Note: If there is any change to this setting, you will need to power off and

restart the system for the change to take effect. Please refer to Intel’s web

site for detailed information.

No Execute Mode Memory Protection (Available when supported by the

CPU and the OS.)

Set to Enabled to enable Execute Disable Bit and allow the processor to classify

areas in memory where an application code can execute and where it cannot, and

thus preventing a worm or a virus from inserting and creating a ﬂ ood of codes to

overwhelm the processor or damage the system during an attack. The options are

Disabled and Enabled.

Note: For more information regarding the hardware/software support for

this function, please refer to Intel's and Microsoft's web sites.

Enhanced Intel Speed Step Support (Available when supported by the

CPU.)

Select Enabled to use the Enhanced Intel SpeedStep Technology and allows the

system to automatically adjust the processor voltage and core frequency in an effort

to reduce power consumption and heat dissipation. The options are Enabled (-C

States, GV1/GV3 are enabled), GV1/GV3 Only (C States: Disabled), C-States Only

(-G1/G3: Disabled), and Disabled (-C States, GV1/GV3 are disabled).
