store frequently accessed instructions and data. Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM. The choices are:

Enabled / Disabled

Hyper-Threading Technology

This option allows you to enable or disable Hyper-Threading Technology. Hyper-Threading Technology is a form of simul- taneous multi-threading technology (SMT) where multiple threads of software applications can be run simultaneously on one processor. This is achieved by duplicating the archi- tectural state on each processor, while sharing one set of pro- cessor execution resources. Hyper-Threading Technology also delivers faster response times for multi-tasking workload environments. By allowing the processor to use on-die resources that would otherwise have been idle, Hyper- Threading Technology provides a performance boost on multi-threading and multi-tasking operations. The choices are:

Enabled / Disabled

Note: Hyper-Threading Technology is applicable only for Intel processors. It does not apply to any other processor including AMD.

Quick Power On Self Test

This option allows the system to skip self tests (POST) for faster startup. The choices are:

Enabled / Disabled

Boot Sequence

This setting controls the order that the BIOS uses to look for a boot device from which to load the operating system during the boot process. The boot sequence options are shown below:
