BIOS SETUP

BIOS IntroductionThe Award BIOS (Basic Input/Output System) installed in yourcomputer system’s ROM supports Intel® Pentium® 4 processors. TheBIOS provides critical low-level support for a standard device such asdisk drives, serial ports and parallel ports. It also adds virus andpassword protection as well as special support for detailed fine-tuning ofthe chipset controlling the entire system.

BIOS SetupThe Award BIOS provides a Setup utility program for specifying thesystem configurations and settings. The BIOS ROM of the system storesthe Setup utility. When you turn on the computer, the Award BIOS isimmediately activated. Pressing the <Del> key immediately allows youto enter the Setup utility. If you are a little bit late pressing the <Del>key, POST (Power On Self Test) will continue with its test routines, thuspreventing you from invoking the Setup. If you still wish to enter Setup,restart the system by pressing the ”Reset” button or simultaneouslypressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart byturning the system Off and back On again. The following message willappear on the screen:

Press <DEL> to Enter Setup

In general, you press the arrow keys to highlight items, <Enter> toselect, the <PgUp> and <PgDn> keys to change entries, <F1> for helpand <Esc> to quit.

When you enter the Setup utility, the Main Menu screen will appear onthe screen. The Main Menu allows you to select from various setupfunctions and exit choices.

Hard Disk Boot PriorityThis item allows you to set the priority for hard disk boot. When youpress enter, the selections shows the current hard disks used in yoursystem as well as the Bootable Add-in Card that is relevant to otherboot sources media such as SCSI cards and LAN cards.

Virus WarningThis item protects the boot sector and partition table of your hard diskagainst accidental modifications. If an attempt is made, the BIOS willhalt the system and display a warning message. If this occurs, you caneither allow the operation to continue or run an anti-virus program tolocate and remove the problem.

CPU L1 and L2 CacheCache memory is additional memory that is much faster thanconventional DRAM (system memory). CPUs from 486-type on upcontain internal cache memory, and most, but not all, modern PCs haveadditional (external) cache memory. When the CPU requests data, thesystem transfers the requested data from the main DRAM into cachememory, for even faster access by the CPU. These items allow you toenable (speed up memory access) or disable the cache function. Bydefault, these items are Enabled.

Hyper-Threading TechnologyHyper-Threading Technology enables two logical processors on a singlephysical processor by replicating, partitioning, and sharing the resourceswithin the Intel NetBurst microarchitecture pipeline.
