Chapter 4: BIOS

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 Enabled. The options are Disabled and Enabled.

Hardware Prefetch (*Available when supported by the CPU.)

Set this option to Enabled to enable the hardware components that are used in conjunction with software programs to prefetch data in order to shorten execution cycles and maximize data processing effi ciency. The options are Disabled and Enabled.

Direct Cache Access (*Available when supported by the CPU.)

Set to Enable to route inbound network IO traffi c directly into processor caches to reduce memory latency and improve network performance. The options are Disabled and Enabled.

DCA Delay Clocks(*Available when supported by the CPU.)

This feature allows the user to set the clock delay setting from snoop to prefetch for Direct Cache Access. Select a setting from 8 (bus cycles) to 120 (bus cycles) (in 8-cycle increment). The default setting is 32 (bus cycles).

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

Select Enabled to use Intel's Virtualization Technology and allow one platform to run multiple operating systems and applications in independent partitions, creating multiple "virtual" systems in one physical 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.

Intel EIST Support (*Available when supported by the CPU.)

Select Enabled to use the Enhanced Intel SpeedStep Technology and allow the system to automatically adjust processor voltage and core frequency in an effort to reduce power consumption and heat dissipation. The options are Enabled and Disabled. Please refer to Intel’s web site for detailed information.
