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 here 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 the <F1> key. A pop-up help menu will appear to
provide you with the information you need. <F5> loads the last set values,
<F6>&<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 acci-
dental 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 recommended because conflicts with new operating sys-
tems. Installation of new operating systems require that you disable this to prevent
write errors.
CPU Level 1 Cache / CPU Level 2 Cache (Enabled)
These fields allow you to choose from the default of Enable or choose Disable to
turn on or off the CPU’s Level 1 and Level 2 built-in cache.
BIOS Update (Enabled)
This functions as an update loader integrated into the BIOS to supply the Pentium
Pro Processor(s) with the required data. The BIOS will load the update on all pro-
cessors during system bootup in the default position of Enabled.
