BIOS Features
CPU Level 1 Cache / CPU Level 2 Cache (Enabled)
These fields allow you to choose from the default of Enabled or choose Dis-
abled 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 pro-
cessors during system bootup in the default position of Enabled.
Turbo Mode (Disabled)
Leave on default setting 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 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.
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; D,A; E,A; F,A; C only; LS/
ZIP, C; LAN, A, C; and 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 in-
stead 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, Analy-
sis and Reporting Technology) system which utilizes internal hard disk drive
monitoring technology. This feature is normally disabled because system
resources used in this feature may decrease system performance.
