(BIOS Features)
Quick Power On Self Test
This field speeds up the Power-On Self Test (POST) routine by skipping retesting a
second, third, and fourth 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
When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This 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
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.
Boot Up Floppy Seek
When enabled, the BIOS will seek the floppy “A” drive one time. By setup default,
this field is set to Disabled.
Floppy Disk Access Control
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
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.
Security Option
When you specify a Supervisor Password and/or User Password (explained later in
this section), the Security Option field determines when the system prompts for the
password. The default setting is System, where the system prompts for the User
Password every time you start your system. The other option is Setup, where the
system goes through its startup routine unless the Setup utility is called, when the
system prompts for the Supervisor Password.
PS/2 Mouse Function Control
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.
