(BIOS Features)
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 (C,A)
This field determines which logical drive (not partitions) the system looks first for
an operating system. Options are A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C
only, A,C. The setup default setting is to check first the hard disk and then the floppy
drive; that is, C, A.
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.
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.
Security Option (System)
This field determines when the system prompts for the password. The default set-
ting is System, where the system prompts for the User Password every time you boot
up. The other option is Setup, where the system always boots up, and prompts for
the Supervisor Password only when the Setup utility is called up. You can specify a
password by using the Supervisor Password or User Password option from the main
screen as explained later in this section.
PS/2 Mouse Function Control (Auto)
The default of Auto allows the system to detect a PS/2 Mouse on bootup. If de-
tected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expan-
sion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expan-
sion cards and therefore the PS/2 Mouse will not function.
