BIOS features
Virus
warning: When Enabled if any
attempt to access the Boot sector or Partition table is made
the BIOS will warn you & either ask you too allow it to
make changes or disable any changes. While safer to leave enabled
it can interfere with certain updates & programs,
particularly Partition Magic. I'd recommend leaving it set
to disabled.
CPU L1: Make sure to enable
this if not already enabled. The L1 cache is effectively
extremely fast RAM, running at the same speed as the
processor.
CPU L2
cache: Make sure to enable
this if not already enabled. Some PC's (e.g. K6-3) may
contain a L3 cache. Although most won't, but enable
it if it does. The L2 cache is effectively extremely fast
RAM, although the L2 cache generally runs at a fraction of
CPU speed. On Pentium 3 E, or EB models the L2 cache runs at
the same speed as the processor.
CPU L2
cache ECC checking: set this to enabled. It will check your L2 cache for errors & can fix some
of them. This will improve to the stability of your PC.
Quick power
on self test: When booting up a series of tests are
run on a system. Enabling this feature will simplify these
tests resulting in a faster boot-up. You should Disable this
if your system is experiencing problems.
Boot order: For fastest boot up select your hard-drive only, usually C:.
If you encounter problems you can change this later on.
First boot
device: Selects the first
bootable device, choose where your operating system is
stored, usually HDD-0
(Choose SCSI if appropriate). If you need to boot from a Floppy disk or
CD-ROM, select appropriately. If this fails it will check
the second boot device for a bootable media. NOTE - For
optimal boot time set this to wherever your OS is stored.
Second boot
device: Selects the second
bootable device, where your operating system is stored,
usualy HDD-0. If
this fails it will check the third boot device for a
bootable media. NOTE - For optimal boot time set this to Disabled.
Third boot
device: Selects the third
bootable device. If this fails it will check the other boot
device for a bootable media. NOTE - For optimal boot time
set this to Disabled.
Boot other
device: Selects the other
bootable device. NOTE - For optimal boot time set this to Disabled.
Swap Floppy
drive: This allows for quick swapping off floppy drive names, i.e. your
A: drive changes to B: & B: changes to A:. By default
this is Disabled
& should be left at this unless you have, 1. - Multiple
floppy drives (unlikely) & Need to swap around their
drive names without having to swap cables around.
Boot up
floppy seek: Use this setting to determine whether or not the BIOS will try to
detect a FDD (Floppy
Disk Drive) in your
system. If enabled
& no FDD is present then an error message will be
displayed. I'd recommend setting this to disabled
to skip this test & improve boot time.
Boot from
floppy: disable this, if
something happens you can re-enable it, but for now it slows
boot-time. Only needed when you want to load from a bootable
floppy, e.g. When wanting to flash your BIOS.
Boot up NumLock status: On or Off, this sets
whether or not the NumLock key is enabled (on) when booting
up. Its a matter of preference, although I find having the
keyboard light on annoying. Either way its only a minor
cosmetic setting for booting.
