BIOS Features Setup
BIOS Features Setup consists of configuration entries that allow you to improve
your system performance, or let you set up some system features according 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
Virus Warning (Disabled)
This field protects the boot sector and partition table of your hard disk against accidental
modifications. Any attempt to write to them will cause the system to halt and display a
warning message. If this occurs, you can either allow the operation to continue or use a
bootable virus-free floppy disk to reboot and investigate your system. This setting is rec-
ommended because of conflicts with new operating systems or some programs. Installa-
tion of these programs requires that you disable Virus Warning to prevent write errors.
CPU Internal Cache (Enabled)
Choose Disable to turn off the CPU’s built-in level 1 cache.
External Cache (Enabled)
Choose Disable to turn off the CPU’s external level 2 cache (Pentium Pro is built-in).
Quick Power On Self Test (Enabled)
This field speeds up the Power-On Self Test (POST) routine by skipping retesting a
second, third, and forth time. Setup default setting for this field is Enabled. A com-
plete test of the system is done on each test.
