Legacy USB Support
This setting allows you to enable support for the Legacy USB devices. The settings are Enabled
and Disabled.
Caution: Take caution when changing the Advanced settings. Incorrect values entered
may cause system malfunction. Also, a very high DRAM frequency or incorrect DRAM
timing may cause system instability. When this occurs, revert to the default setting.
Advanced Processor Options
Access the submenu to make changes to the following settings:
CPU Speed
The feature allows the BIOS to display the CPU Speed.
Hyper-threading (*Available when supported by the CPU.)
This setting allows you to Enable or Disable the function of hyper-threading. Enabling hyper-
threading results in increased CPU performance. (Applicable for XP systems.)
Single Logical Processor Mode (*Available when supported by the CPU.)
This feature allows the user to select the Processor Operation Mode. Set to Disabled to allow the
processor to operate in the "single core" mode. Set to Enabled to allow the processor to operate
in the "multi-core" (dual-core) mode.
Machine Checking
Set to Enabled to allow the operating system to debug a system crash after a reset. The options
are Disabled and Enabled.
L3 Cache (*Available when supported by the CPU.)
Set to Enabled to enable L3 cache in the CPU to enhance system performance. The options are
Disabled and Enabled.
Thermal Management 2 (*Available when supported by the CPU.)
If enabled, this feature allows you to select between Thermal Manager 1 and Thermal Manager 2.
Set to Disable to activate the function of TM1, allowing the CPU to regulate its power
consumption based upon the modulation of the CPU Internal clock when the CPU temperature
reaches a pre-defined overheat threshold. Set to Enable to activate the function of TM2, which
will allow the CPU to reduce its power consumption by lowering the CPU frequency and the CPU
voltage when the CPU temperature reaches a pre-defined overheat threshold.
Note: please refer
to Intel's web site for detailed information.
Adjacent Cache Line Prefetch
The CPU fetches the cache line for 64 bytes if Disabled. The CPU fetches both cache lines for
128 bytes as comprised if Enabled.
C1 Enhanced Mode (*Available when supported by the CPU.)
Set to Enabled to enable the Enhanced Halt State. The options are Enabled and Disabled.
Note:
please refer to Intel's web site for detailed information.
No Execute Mode Memory Protection
Enable this feature to enable the functionality of Execute Disable Bit and allow the processor to
classify areas in the memory where an application code can execute and where it cannot, and
thus preventing a worm or a virus from inserting and creating a flood of codes that will overwhelm
the processor or damage the system during an attack.
Note: this feature is available when your
OS and your CPU support the function of Execute Disable Bit.
The options are Disabled and
