when hold­ing 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 compo­nents against damage from static electricity, you should follow some precau­tions whenever you work on your computer.

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 W ide 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.

SCSI 5MB/sec (8bit) N/A
Fast SCSI (II) 10MB/sec (8bit) 20MB/sec
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. The W ide 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 addi­tional devices with additional cables. You can connect up to seven devices to
the Fast SCSI bus and fifteen devices to the Wide SCSI bus.

III. INSTALLATION

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 W ide 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 prop­erly . 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 termi­nate 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

8

ASUS PCI-AS300 User's Manual

III. INSTALLATION

T o terminate the other end of either SCSI bus, you will need to refer to the documen­tation 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.

III. INSTALLATION

The SCSISelect Configuration Utility

To access SCSISelect, press <CTRL A> 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 . Y ou can select either Configure/View Host Adapter
Settings or SCSI Disk Utilities.

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. T o 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 mes­sage 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.

(Utilities)

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 supplied Adapted EZ­SCSI W indows utility to enable using non-disk SCSI devices such as scanners, tape
drives, or CD-ROM drives. It also allows mounting and removing removable me­dia 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.

SCSI Device Troubleshooting

Review this checklist if your newly-installed SCSI disk drives, CDROM drives, and
other devices do not seem to work properly:

• Be sure that termination is correctly set for all devices on the SCSI bus, as

described in your host adapter documentation.

• Be sure there are no hardware conflicts such as devices in your computer try-

ing to use the same interrupts (IRQs) or DMA channels.

• Be sure the cables connecting the external and internal SCSI devices and the

host adapter are attached securely . Also be sure the pin-1 orientation is correct
for internal cables. See the host adapter documentation for more information.

• Be sure that each SCSI device connected to the host adapter has a unique SCSI

ID.

• Be sure CD-ROM drives and other SCSI devices are attached to a power source

installed correctly?

Miniport drivers are a new kind of 32bit protect mode device driver used by Win­dows95 and WindowsNT to control host adapters and other kinds of devices. Win­dows95 and W indowsNT include a set of miniport drivers for various types of SCSI
host adapters. The host adapter miniport driver is automatically installed and con­figured during Windows95 and WindowsNT installation if your host adapter is al­ready installed. To make sure the driver is installed correctly in systems running
Windows95, open the Control Panel, double-click on System, and click the Device
Manager tab. Then double-click the SCSI Controllers icon; you should see the model
name of the SCSI host adapter(s) installed in your system.

What if there is no SCSI controllers icon under Device Manager, or the model
name of the SCSI chipset does not appear under Device Manager?

If the SCSI controllers icon or your host adapter’s model name do not appear , open
Control Panel and double-click the Add New Hardware icon. Let Windows search
for the host adapter by selecting Yes on the second screen of the Add New Hardware
Wizard.

and are turned ON.

If Windows does not detect the host adapter, run the Add New Hardware Wizard
again. This time, select No on the second screen of the wizard, then select SCSI
controllers on the next screen. Select the name of your host adapter when it appears.

IV. ADAPTEC EZ-SCSI UTILITY

If the name of your SCSI chipset does not appear, you may be able to find its
miniport driver on the Windows95 CD-ROM. Follow these steps:

1 Place the Windows95 CD-ROM in your CDROM drive and run the Add New

Hardware wizard.

2 Select No on the second screen, and select SCSI controllers on the next screen.
3 Click on the Have Disk button, then click the Browse button.
4 Look in the \drivers\storage directory of the CDROM and select the name of

your SCSI host adapter if it appears.

What if a yellow exclamation point or a red X appears in Device Manager in
front of my host adapter?

This means there is some kind of resource problem. First, see if the names of any
host adapters appear that are not actually installed in your computer . If so, select the
name and click Remove. If a red X appears in front of your host adapter name,
remove all the host adapter references under SCSI Controllers and run Add New
Hardware, as described in the previous question/answer. If a yellow exclamation
point appears in front of your host adapter name, the resources that the driver uses
probably do not match the resources used by the hardware. Double-click the host
adapter name, then click on the Resource tab. Deselect the Use automatic settings
box and edit the resources (Interrupt Request, Direct Memory Access, etc.) so they
match those used by the host adapter . If the problem still remains, there is probably
a hardware resource conflict between the host adapter and other hardware in your
computer. You can fix this by changing the hardware resource settings. (See your
hardware documentation.)

What do I need to do if I want to use another host adapter?

1 Open the Control Panel, double-click on System, and click the Device Man-

ager tab.

2 Double-click the SCSI Controllers icon, select the name of the old host adapter,

and click Remove.

3 Turn OFF the computer and physically remove the currently installed host

adapter.

4 Install the new host adapter according to the instructions in the hardware docu-

mentation.

5 Turn the computer ON. If the new host adapter supports Plug and Play, Win-

dows will install and configure it automatically . Otherwise, run Add New Hard­ware to make sure the new driver is loaded.

If I am running under Windows95, do I need lines for the Adaptec real mode
ASPI drivers and mscdex in my config.sys and autoexec.bat files?

Usually, you do not need to use these real mode ASPI drivers, because the new
Windows miniport drivers support most SCSI host adapters and SCSI devices. How­ever, you need to load the drivers (including mscdex, if you have a CDROM drive)
if any of the following is true:

• You are running in MSDOS mode

• Y ou are using a scanner or another SCSI device with config.sys- or autoexec.bat-

based drivers, such as HP’s sjiix.sys

• You have an older model SCSI-1 CDROM drive that Windows95 does not

support

• You are using a CD-Recorder drive (however, some newer models of CD-

Recorder drives can use the embedded Windows miniport drivers)

To install the Adaptec EZSCSI DOS drivers, click the Start button and select Re-
start the computer in MS-DOS mode. When the DOS prompt appears, follow the
Quick Start instructions for DOS.

My CDROM drive doesn’t work properly under Windows95.

Some older models of SCSI CDROM drives are not compatible with the embedded
Windows95 CDROM driver. You can add support for the CDROM drive by doing
the following:

1 Click the Start button and select Restart the computer in MS-DOS mode.
2 When the DOS prompt appears, follow the Quick Start instructions for DOS.

• Comment out the line that loads mscdex.exe in the autoexec.bat file.

• Change the /L switch on the line that loads mscdex.exe in the autoexec.bat file

Information for DOS/Windows 3.1x Users

The following information may be useful if you install Adaptec EZSCSI on a com­puter running DOS, Windows 3.1x, or Windows for Workgroups3.1x.

NOTE: The Windows95/WindowsNT Troubleshooting section on page 6 de­scribes a few situations when you may need to use the DOS/Windows3.1x driv­ers and ASPI managers under Windows95 or WindowsNT.

DOS and Windows3.1x Device Drivers

Device drivers are software programs that enable your computer to communicate
with SCSI devices such as hard disk drives, CDROM drives, and scanners. Each
kind of device requires a different device driver. Adaptec EZSCSI includes several
DOS/Windows3.1x device drivers that are copied to your hard disk during installa­tion. Adaptec EZSCSI adds command lines to your config.sys and autoexec.bat files
to load these device drivers if it finds these kinds of devices on your computer.

To learn more about the Adaptec EZSCSI device drivers, including their command
line option information, see the online Adaptec EZSCSI Online Reference, a Win­dows Help application.

DOS and Windows3.1x ASPI Managers

ASPI (Advanced SCSI Programming Interface) managers are software programs
that enable the SCSI device drivers, your host adapter, and your SCSI devices to
communicate with each other. ASPI managers are written for a specific operating
system, such as DOS, and a specific family of Adaptec host adapters.

Adaptec EZSCSI includes several ASPI managers for DOS/Windows3.1x. When
you install Adaptec EZSCSI on these operating systems, it detects what kind of host
adapter is installed in your computer and automatically configures your system with
the correct ASPI manager. To learn more about these ASPI managers, including
their command line option information, see the Adaptec EZSCSI Online Reference,
a Windows Help application.

DOS Formatting Utilities

Adaptec EZSCSI includes several DOS-based formatting utilities:

Low-level Formatter (scsifmt)

Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives,
removable media, Floptical® drives, and magneto-optical drives. You can also use
it to scan a disk device for surface defects before you store data on it.

Run scsifmt from the DOS prompt, not from the W indows MSDOS prompt. Before
you run it, be sure the disk devices you want to format are connected to the host
adapter and that they are powered. Then follow these steps:

1. Change to the directory where scsifmt.exe is located (usually c:\scsi), type
scsifmt at the DOS prompt, and press Enter.

NOTE: If you are formatting a SCSI disk device that supports more than
one LUN (for example, Iomega’ s Bernoulli dual multidrive) type scsifmt /
L at the command line.

If you select Verify, you can press Esc at any time to stop the verification

process. (This does not damage the disk.) If the utility finds bad blocks on the
disk, it displays information about them. You can reassign the bad block(s) to
prevent data from being stored there.

6. Repeat steps 3, 4, and 5, as needed, to format or verify other disk devices.
When you are finished, press Esc to exit.

22 ASUS PCI-AS300 User's Manual

IV. ADAPTEC EZ-SCSI UTILITY

Formatter and Partitioner (afdisk)

Use the DOS-based afdisk utility to partition and format SCSI hard disk drives,
Floptical drives, and magneto-optical drives. You can also use afdisk to remove
DOS and non-DOS partitions from a disk drive and to format removable media in
standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format.

NOTE: Use afdisk only if the disk device is not controlled by the host adapter
BIOS—that is, if the host adapter does not have a BIOS or if its BIOS is not en­abled. If the disk device is controlled by the host adapter BIOS, use the DOS fdisk
utility to partition and format the disk device. (See the MSDOS documentation.)

Run afdisk from the DOS prompt only, not from the Windows MSDOS prompt.
Before you run it, be sure the disk devices you want to format and partition are
connected to the host adapter and that they are powered. Then follow these steps:

1. Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk
at the DOS prompt, and press Enter.

Information about your SCSI disk devices appears on the screen. (The number
that appears after Target is the device’s SCSI ID.)

2. Use the arrow keys to move the highlight bar to the disk device you want to
partition, then press Enter.

- If the selected disk device is controlled by the host adapter BIOS, you can
view information about it but you cannot partition it with afdisk (Use the DOS
fdisk and format utilities.)

- If the selected disk device is unpartitioned, you must partition it before you
can format it. To do this, follow the instructions on the screen. (Press F1 to see
an explanation of the partitioning options.)

Information about the selected disk device appears in the lower left of the
screen. Disks smaller than 1Gigabyte have 64 heads, 32 sectors per track, and
cylinders equal to the number of MBytes of available capacity. Disks larger
than 1Gigabyte have 255 heads, 63sectors per track, and one cylinder per
8MBytes of available capacity.

Where:

SYNTH: 1 Specifies internal synthesizer (default)

2 Specifies audio hardware MIDI port

MAP: G Specifies General MIDI file format

E Specifies Extended MIDI file format (default)
B Specifies Basic MIDI file format

Maximum Recording Rates for the Audio Hardware

The sampling rate used for recording is largely influenced by your computer’s main
processor. To obtain 16-bit digital audio using Windows, the following maximum
recording rates are suggested.

SYSTEM RECORDING RATE

386 and above Stereo - 44KHz

Mono - 44KHz

386 SX and below Stereo - 22KHz

Mono - 44KHz

To obtain optimal performance, try configuring the audio hardware to use a high
DMA (Direct Memory Access) channel under Windows. Refer to your audio hard­ware Getting Started Manual for more information on setting up the sound card to
use a high DMA channel.
