IV. BIOS SOFTWARE
Processor Serial Number (Disabled)
The Processor Serial Number is a unique electronic number that is added to every
Pentium III processor to help verify the identity of the user across the Internet. Set
this field to Enabled when you need increased security for doing business online, or
e-commerce. Otherwise, set it to Disabled for greater anonymity when surfing the
Internet.
CPU Level 1 Cache / CPU Level 2 Cache (Enabled)
These fields allow you to choose from the default of Enabled or choose Disabled to
turn on or off the CPU's Level 1 and Level 2 built-in cache.
CPU Level 2 Cache ECC Check (Disabled)
This function controls the ECC check capability in the CPU level 2 cache.
BIOS Update (Enabled)
This functions as an update loader integrated into the BIOS to supply the processor
with the required data. The BIOS will load the update on all processors during sys-
tem bootup in the default position of Enabled.
Turbo Mode (Enabled)
Leave this on the default setting of Enabled for best performance.
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.
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.
Boot Sequence (A,C)
This field determines where the system looks first for an operating system. Options
are A,C; C,A; A,CDROM,C; CDROM,C,A; CDROM,A,C; D,A; E,A; F,A; C only; LS/
ZIP,C; LAN,A,C; LAN,C,A. The setup default setting, A, C, is to check first the
floppy disk and then the hard disk drive.
Boot Up Floppy Seek (Disabled)
When enabled, the BIOS will seek drive A once.
Floppy Disk Access Control (R/W)
This allows protection of files from the computer system to be copied to floppy
disks by allowing the setting of Read Only to only allow reads from the floppy disk
drive but not writes. The setup default R/W allows both reads and writes.
IDE HDD Block Mode Sectors (HDD MAX)
This field enhances hard disk performance by making multi-sector transfers instead
of one sector per transfer. Most IDE drives, except older versions, can utilize this
feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32.
HDD S.M.A.R.T. capability (Disabled)
This allows the enabling or disabling of the S.M.A.R.T. (Self-Monitoring, Analysis
and Reporting Technology) system which utilizes internal hard disk drive monitor-
ing technology. This feature is normally disabled because system resources used in
this feature may decrease system performance.
