BIOS Features Setup

This "BIOS Features Setup" option consists of configuration entries that allow you
to improve your system performance, or let you set up some system features accord-
ing to your preference. Some entries are required by the motherboard's design to
remain in their default settings.
A section at the lower right of the screen displays the control keys you can use. Take
note of these keys and their respective uses. If you need information on a particular
entry, highlight it and then press <F1>. A pop-up help menu will appear to provide
you with the information you need. <F5> loads the last set values, <F6> and <F7>
loads the BIOS default values and Setup default values, respectively.
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.

Details of BIOS Features Setup

CPU Internal Core Speed
Select your CPU speed in this field or select Manual for customized selections of the
"CPU Core:Bus Freq. Multiple: XXx" (2.0x-8.0x with increments of 0.5) and the
"CPU Bus Frequency: XX" (50, 60, 66, 68, 75, 83). If you set the CPU speed in excess
of the CPU specifications, your computer may not boot up next time. Remove and
reinstall the CPU in order to reset the speed to the last successful bootup speed.
Boot Virus Detection (Enabled)
This field allows you to set boot virus detection, ensuring a virus-free boot sector.
This new antivirus solution is unlike native BIOS tools, which offer limited virus
protection typically by write-protecting the partition table, because it guards against
boot virus threats earlier in the boot cycle, that is, before they have a chance to load
into your system, ensuring your computer boots to a clean operating system. The
system halts and displays a warning message when it detects a virus. If this occurs,
you can either allow the operation to continue or use a bootable virus-free floppy disk
to restart and investigate your system. Because of conflicts with new operating sys-
tems, for example, during installation of new softwares, you may have to set this to
Disabled to prevent write errors.
