Serial and Parallel Interfaces
The mainboard connectors for the two serial ports and the par-
allel port are similar to that of the SCSI interface. Each connector's
Pin 1 location is also indicated. The colored edge of each connecting
cable
must
be on the Pin 1 side of the connector.

Connecting
The Power
Supply
To connect the leads from the power supply, first make sure the
it is unplugged. Most power supplies have two leads. Each lead has
six wires, two of which are black. Orient the connectors so the black
wires are in the
middle.

The PCl-SC200
SCSI Interface
Card
This
mainboard can
use
an optional SCSI interface card,
the PCI-
SC200,
to
connect
both internal
and external
devices to
your system.
The
card works with
the
SCSI BIOS on
the
mainboard.
The card
in-
terface has the
same features as the on-board SCSI interface with
the
addition of
the
external connector.
If
you install
the
PCI-SC200
it
will
function as a second SCSI bus. This means you can connect devices
to both the
on-board connector and
the
card. Alternatively, you can
connect
all devices
to the
card only.
To use
the
PCI-SC200, you must also enable
the
"NCR SCSI Firm-
ware" option in
the
Award BIOS Setup
Utility program.
Refer to the
section on Chipset Setup
in
Chapter 3 for more about
this.
To install
the
PCI-SC200, you need to
set
it
up first.
The setup pro-
cedure is
explained
here. The basic card installation procedure is ex-
plained in Chapter 2.
