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.
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 acciden-
tal 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 con-
tinue or use a bootable virus-free floppy disk to reboot and investigate your system.
This setting is recommended because conflicts with new operating systems. Installa-
tion of new operating systems require that you disable this 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
complete test of the system is done on each test.
HDD Sequence SCSI/IDE First (IDE)
When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This new feature allows a SCSI hard disk
drive to be the boot disk when set to SCSI. This allows multiple operating systems
to be used on both IDE and SCSI drives or the primary operating system to boot
using a SCSI hard disk drive.
