Parallel Mode

This category allows you to select from the following
options: Output Only (AT-compatible) (the default), Bidi-
rectional (Personal System/2 [PS/2]-compatible), and
ECP (extended capabilities port).

Diskette Controller

Selecting Enabled (the default) enables the on-board dis-
kette drive controller.

Onboard SCSI

Selecting the Enabled (the default) option enables the on-
board PCI SCSI controller and scans the associated
ROM. In order for the system to boot from a drive
attached to the on-board SCSI controller, the drive must
be enabled. Selecting Disabled causes the BIOS to mask
the presence of a device.

PCI Scan Sequence

This category determines the order in which PCI devices
are scanned by the system, and it allows you to select the
built-in SCSI controller or an optional PCI expansion
card SCSI controller as the boot device. The options are:
•
Embedded Devices First (the default)
•
Slot Devices First
PS/2 Mouse
Setting PS/2 Mouse to Enabled (the default) allows an
installed PS/2 mouse to function. Disabling PS/2 Mouse
frees interrupt request (IRQ) 12, but it also prevents any
installed PS/2 mouse from functioning.
