(BIOS Features)
CPU Internal Cache (Enabled)
These fields allow you to Enable or Disable the CPU’s “Level 1” primary cache.
Caching allows better performance.
External Cache (Enabled)
These fields allow you to Enable or Disable the CPU’s “Level 2” secondary cache.
Caching allows better 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. 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. 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 (C,A)
This field determines where the system looks first for an operating system. Options
are C,CDROM,A; CDROM,C,A; A,C; C,A The setup default setting is to check first
the hard disk and then the floppy drive; that is, C, A.
Swap Floppy Drive (Disabled)
When enabled, the BIOS swaps floppy drive assignments so that Drive A becomes
Drive B, and Drive B becomes Drive A under DOS.
Boot Up Floppy Seek (Disabled)
When enabled, the BIOS will seek the floppy "A" drive one time.
Floppy Disk Access Control (R/W)
This allows protection of files from the computer system to be copied to floppy
drives by allowing the setting of Read Only to only allow reads from the floppy but
not writes. The setup default R/W allows both reads and writes.
Boot Up NumLock Status (On)
This field enables users to activate the Number Lock function upon system boot.
The setup default setting for this field is On.
Boot Up System Speed (High)
This has not function and should be left at the setup default of High.
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. By setup default, this field is set to HDD MAX, other selections are Dis-
abled 2, 4, 8, 16, and 32.
