IV. BIOS SOFTWARE

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. Setup default setting for this field is Enabled. A complete test of the system is done on each test.

HDD Sequence SCSI/IDE First (New Feature!)

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 (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.Boot Up System Speed (High)This has no function and should be left on the setup default.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.
