Installation Steps
Before using your computer, you must follow the six steps as follows:
1. Set the card's jumpers
2. Install Expansion Card
3. Connect device cables
4. Configure SCSI ID numbers and termination
5. Setup the oncard SCSISelect Utility if you need to change the defaults
6. Setup the BIOS Software.
1. Jumpers
Some hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the card. The jumper settings will be described numerically such as
[----], [1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 re-
spectively. Pin 1 for our cards is always on top
Pin 1
or on the left
Pin 1
when hold-
ing the connectors to the left. A "1" is written besides pin 1 on jumpers with three
pins. The jumpers will also be shown graphically such as to connect pins
1&2 and to connect pins 2&3. Jumpers with two pins will be shown as
for short (On) and for open (Off). For manufacturing simplicity, the jumpers
may be sharing pins from other groups. Use the diagrams in this manual instead of
following the pin layout on the board. Settings with two jumper numbers require
that both jumpers be moved together. To connect the pins, simply place a plastic
jumper cap over the two pins as diagramed.
WARNING: Computer motheboards and components contain very delicate
Integrated Circuit (IC) chips. To protect the motherboard and other compo-
nents against damage from static electricity, you should follow some precau-
tions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Hold components by the edges and try not to touch the IC chips, leads, or
circuitry.
3. Use a grounded wrist strap before handling computer components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

Audio Adapter Base I/O Addresses
I/O addresses (or I/O address range) are areas of memory used by your computer's
microprocessor to distinguish among various peripheral devices connected to your
system when sending or receiving data. There are several such devices on your
audio card. These devices are listed with their factory default I/O addresses.
I/O Address occupied by theAudio Card.
I/O Address Range Usage

2. Install the Expansion Card
1. Unplug your computer. Open the system case and remove the slot
cover for the expansion slot you wish to use.
2. Align the connectors and insert the card into the expansion slot
firmly, making sure that the connectors are evenly inserted.
3. Install the card's mounting bracket to the system's case.
4. Attach SCSI cables from your internal SCSI devices and the audio
cable from your CD-ROM.
5. Close your system case and power on your computer in order to setup
the software.
3. Connect Cables
Once the card is installed in your system you should connect the cables for whatever
devices you want to attach to the card. These divide into two types, CD-ROM audio
cables and SCSI bus cables.
Audio Cables
As noted on the card diagram, there are connections for three types of CD-ROM audio
cables. If you have a CD-ROM installed in your system, connect it to the appropriate
connector. Note that many drives manufactured by vendors other than the three noted
have audio cables that are compatible with one of these three connectors. Review the
documentation that came with the drive for further information.
SCSI Cabling
The card has two SCSI cable connectors, one for 8-bit Fast SCSI and the other for
16-bit Wide SCSI. SCSI devices must be connected in a direct line forming a "bus"
with no branching.
SCSI Cable Limits:
SCSI TYPE Cable Length Limit
Single-ended SCSI 6 meters (19.7 feet)
Fast Single-ended SCSI 3 meters (9.8 feet)
WARNING: This adapter is for "Single-Ended" SCSI devices only. Do not
connect "Differential" SCSI devices to this adapter.

Wide SCSI (III) 20MB/sec (16bit) 40MB/sec
Connecting Cables
1. When you connect a SCSI cable to this card, you must align the cable so that
the Pin 1 side of the cable connector is at the Pin 1 side of the cable connector
on the card. The two SCSI connectors use different cables. The Fast SCSI
connector connects to a 50-pin flat ribbon cable. The Pin 1 side of the ribbon
cable is marked with a colored edge and the Pin 1 side of the connector on the
card is labelled on the card. TheWide SCSI connector connects to a cable that
has a connector which can only be attached to the card in one orientation,
making the Pin 1 matchup automatic.
2. After you connect the cables to the host adapter, review the subject of SCSI
identification (ID) numbers and termination covered in Section 4. Make sure
that all devices you connect to the SCSI adapter have different ID numbers and
that only the SCSI adapter and the last SCSI device on each bus is terminated.
3. Connect a cable between the host SCSI adapter and an internal SCSI device
installed in your system. If there is more than one device, connect the addi-
tional devices with additional cables. You can connect up to seven devices to
the Fast SCSI bus and fifteen devices to the Wide SCSI bus.

(SCSI ID /Terminate)
4. SCSI ID Numbers & Termination
You must set the SCSI identification numbers and properly terminate the SCSI bus
before you can use the adapter and any peripherals connected to it.
SCSI ID Numbers
Each device on a SCSI bus must have a unique identification number. All SCSI
devices have some means of setting the ID number for the device. The SCSI adapter
must also have an ID number. The default number for the PCI-AS300 is 7. You
should use this unless you know there is a specific need to change it. Consult the
documentation for any other SCSI devices to see how to set their ID numbers. The
recommended numbers are:
SCSI Host Adapter: 7 (Default)
SCSI Hard Disk Boot Device: 0
2nd SCSI Hard Disk: 1
Devices connected to the 8-bit Fast SCSI bus can have numbers from 0 to 7. The
16-bit Wide SCSI bus allows numbers from 0 to 15. SCSI devices vary in how they
set the ID number. Some use jumpers, others have some kind of selector switch.
Refer to the documentation for any devices you install for details on how to set the
SCSI ID number.
SCSI Termination
Both ends of the SCSI bus must be terminated in order for the bus to operate prop-
erly. Since this card only supports internal devices, the SCSI adapter must be at one
end of the bus and must be terminated. The device on the other end of the bus daisy
chain must also be terminated.
Since this card supports two SCSI buses, the card termination can be set up to termi-
nate either one or both buses. The WIDE SCSI bus is divided into "Low" and "High"
bytes, the Low part being equivalent to the 8-bit Fast SCSI bus. If you will use both
SCSI connectors, you must change the default setting. The required settings are
shown in the chart below.
Connector/Bus Used Low High
50-pin connector only ON ON (Default)
68-pin connector only ON ON (Default)
50-pin & 68-pin connector OFF ON

ASUS PCI-AS300 User's Manual 9
To terminate the other end of either SCSI bus, you will need to refer to the documen-
tation for the device at the end of the bus for information on how to terminate the
device. Many devices use either jumpers or a switch to set termination. Others use
resistor modules that must be removed to unterminate the device. It is critical that
the last device, and only the last device be terminated in order of all of the devices
on the bus to operate correctly. This card supplies termination power to the SCSI
bus for devices that need it.
5. Configuring the SCSI Adapter
You probably will not need to change the default configuration of the PCI-AS300
SCSI adapter. In the event that you do need to, a configuration utility, SCSISelect, is
stored on the card. This menu driven utility allows you to control the configuration
of both the SCSI adapter and its interaction with devices connected to it.
After you have installed and connected devices to the card, reassemble your system
according to the instructions in your system documentation. Once your system is
assembled, turn on your computer. You should see a SCSI BIOS banner message
listing connected devices and their ID numbers. If everything is working properly,
you can go ahead and use your system. If you need to change the SCSI adapter
configuration on the PCI-AS300, or if you want to customize the control settings for
an individual SCIS device on the bus, you can run the SCSISelect configuration
utility.
The SCSISelect Configuration Utility
To access SCSISelect, press <CTRLA> when you boot the computer, or when you
see the BIOS banner message listing the attached devices. The SCSISelect screen
will come up. Instructions on how to move the cursor and select options are at the
bottom of the program window. You can select either Configure/View HostAdapter
Settings or SCSI Disk Utilities.

ASUS PCI-AS300 User's Manual 10
Configure/View Host Adapter Settings
If you select the first option, the configuration screen will display. Pressing F6 at
this level will load the adapter's default settings. To make a change, select an option
and press Enter to display a list of possible settings for that option. To abandon
changes after you have made them, press <ESC> and then choose No when a mes-
sage appears asking if you will accept the changes made.
SCSI Disk Utilities
The SCSI Disk Utilities option displays information on SCSI IDs 0 through 15,
listing all devices on the bus including non-disk devices. When you select a device
from the list and press the <ENTER> key, another window pops up giving you the
option of selecting one of two sub-utilities, Format Disk or Verify Media. These
utilities are used for hard disk drives only and will have no effect on other non-disk
SCSI devices.
Format Disk is a SCSI low-level format utility. In general, SCSI hard disks have
already been low-level formatted when you get them, so you generally should not
need to use this.
Verify Media scans the selected drive media for defects, notifies you of any found
and gives you the option of reassigning bad blocks so that data will not be written to
them. Doing this before you start using a disk is a good idea.
Operating System Support
The PCI-AS300 supports both DOS/Windows under MS-DOS 5.0 and up, allowing
you to connect up to seven hard disk drives. You can used the suppliedAdapted EZ-
SCSI Windows utility to enable using non-disk SCSI devices such as scanners, tape
drives, or CD-ROM drives. It also allows mounting and removing removable me-
dia such as CD-ROMs and support for more than eight hard disks under MS-DOS
5.0 or later and more than two hard disks under earlier versions.
In addition, this card supports operating systems other than DOS, including Novell
NetWare, OS/2, OS/2 Warp, Windows NT, SCO Unix, and Unix Ware. You can
refer to the card's software documentation for more information on this.

Troubleshooting
In the event that you have problems getting the PCI-AS300 installed and working
properly, make sure that:
• all the SCSI devices are turned on.
• all the cables connects the SCSI devices in a series.
• all the SCSI devices have a unique ID number on that BUS
• the last SCSI device is terminated.
• the BIOS setup correctly identifies the PCI part of the MediaBus slot
Cannot Boot from your SCSI Disk Drive
If you have any non-SCSI hard disk drives installed in your system, the master non-
SCSI drive will be seen as the boot drive. If there are only SCSI drives installed in
your system and will not boot from the primary drive, check the following:
• Make sure that all hard disk type entries in the BIOS Setup utility's CMOS
setup are set to "None" or "No Drives Installed."
• Make sure the boot drive's SCSI ID is set to 0
• Check that the drive has been properly formatted for the operating system you
are using and that the operating system is installed.
Ifnoneoftheabove solves the problem,back-upthedriveandtryusing the SCSISelect
utility to perform a low-level format and verification and then set an active partition
for the operating system you are using and format the drive using your operating
system's format command.
