Overview  
Ultra160 SCSI on the Adaptec SCSI Card 39160  
The Adaptec SCSI Card 39160 enables you to connect up to 30 SCSI  
devices—such as very large arrays of high-performance HDDs,  
external storage subsystems, clustered configurations, Ultra160 hard  
disk drives, scanners, and CD-ROM drives—to any Intel-based com-  
puter with 64- or 32-bit PCI expansion slots. Ultra160 is a new gener-  
ation of SCSI technology that increases SCSI performance from  
80 MBytes/ sec to 160 MBytes/ sec. In addition to providing much  
greater performance, Ultra160 SCSI enables a maximum allowable  
cable length of 12 meters for optimal connectivity and flexibility.1  
The Adaptec SCSI Card 39160 has two independent SCSI channels,  
each with a maximum throughput of 160 MBytes/ sec.  
SCSI Channel A (marked “CH 1/ A” on the card) has two  
internal connectors and one external connector.  
SCSI Channel B (marked “CH 2/ Bon the card) has one inter-  
nal connector and one external connector.  
For the best data I/ O performance, connect only LVD (Low Voltage  
Differential) devices and LVD cables to the Adaptec SCSI Card  
39160. (LVD devices means Ultra160 and Ultra2 SCSI devices.) If you  
connect non-LVD devices (for example, Fast SCSI or Ultra SCSI  
devices), we recommend that you connect them to SCSI Channel A.  
This allows you to operate Ultra160 and Ultra2 devices at their max-  
1
When only one Ultra2 or Ultra160 SCSI device is connected, the cable length  
can be up to 25 meters (82 feet).

imum speed on Channel B while at the same time using non-LVD  
SCSI devices on Channel A.  
Although the Adaptec SCSI Card 39160 is a 64-bit PCI card, it also  
works in a 32-bit PCI slot. When installed in a 32-bit PCI slot, the  
card automatically runs in the slower 32-bit mode.  
This Users Reference provides information about troubleshooting,  
SCSI termination, and other important topics. It also explains how to  
use the built-in SCSISelect utility if you need to change the Adaptec  
SCSI Card 39160 settings.  
Note: Read the Adaptec SCSI Card 39160 Installation Guide if  
you need instructions on installing the SCSI Card and con-  
necting SCSI devices to it.  
Understanding SCSI  
SCSI (pronounced “scuzzy”) stands for Small Computer Systems  
Interface. SCSI is an industry standard computer interface for con-  
necting SCSI devices (such as a hard disk drive, CD-ROM drive, or  
scanner) to a common SCSI bus.  
A SCSI bus is an electrical pathway that consists of a SCSI adapter  
card (such as the Adaptec SCSI Card 39160) installed in a computer  
and one or more SCSI devices. SCSI cables are used to connect the  
devices to the SCSI adapter card. The Adaptec SCSI Card 39160 has  
two independent SCSI buses (channels).  
For the SCSI bus to function properly, a unique SCSI ID must be  
assigned to the SCSI card and each SCSI device connected to it, and  
the SCSI bus must be properly terminated.  
2
 
 
Overview  
SCSI IDs  
Each device attached to the Adaptec SCSI Card 39160, as well as the  
Adaptec SCSI Card 39160 itself, must be assigned a unique SCSI ID  
number from 0 to 15 for each of the two SCSI buses. A SCSI ID  
uniquely identifies each SCSI device on the SCSI bus and determines  
priority when two or more devices are trying to use the SCSI bus at  
the same time.  
Refer to the devices documentation to set the SCSI ID. Here are  
some general guidelines for SCSI IDs:  
For internal SCSI devices, the SCSI ID usually is set by config-  
uring a jumper on the device.  
For external SCSI devices, the SCSI ID usually is set with a  
switch on the back of the device.  
SCSI ID numbers do not need to be sequential, as long as the  
Adaptec SCSI Card 39160 and each device has a different num-  
ber. For example, on each of the two SCSI buses you can have  
an internal SCSI device with ID 0, and an external SCSI device  
with ID 6.  
SCSI ID 7 has the highest priority on the SCSI bus. The priority  
of the remaining IDs, in descending order, is 6 to 0, then 15 to 8.  
On both SCSI buses (channels) the Adaptec SCSI Card 39160 is  
preset to SCSI ID 7 and should not be changed. This gives the  
card the highest priority on the SCSI bus.  
Most internal SCSI hard disk drives come from the factory pre-  
set to SCSI ID 0.  
If you have 8-bit (or Narrow) SCSI devices, they must use SCSI  
IDs 0, 1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first  
SCSI hard disk drive.  
If you are booting your computer from a SCSI hard disk drive  
connected to the Adaptec SCSI Card 39160, the Boot SCSI ID  
setting in the SCSISelect utility must correspond to the SCSI ID  
of the device from which you are booting. By default, the Boot  
SCSI ID is set to 0. We recommend that you do not change this  
setting.  
In Windows® 95/ 98, you can use the Device Manager to deter-  
mine which SCSI ID is assigned to each installed SCSI device.

Adaptec SCSI Card 39160 User’s Reference  
Terminating the SCSI Bus  
To ensure reliable communication on the SCSI bus, the ends of the  
SCSI bus must be properly terminated. This is accomplished when  
the device at the end of each cable, or the end of the cable itself, has a  
terminator installed (or enabled). Terminators must be removed, or  
termination must be disabled, on devices between the ends of each  
cable.  
Since the method for terminating a SCSI device can vary widely,  
refer to the devices documentation for instructions on how to  
enable or disable termination. Here are some general guidelines for  
termination:  
Internal Ultra160 and Ultra2 SCSI devices come from the fac-  
tory with termination disabled and cannot be changed. Proper  
termination for these internal devices is provided by the built-  
in terminator at the end of the 68-pin internal LVD SCSI cable.  
Termination on Wide SCSI, Narrow SCSI, and Ultra SCSI  
devices usually is controlled by manually setting a jumper or a  
switch on the device, or by physically removing or installing  
one or more resistor modules on the device.  
Termination on most external SCSI devices is controlled by  
installing or removing a SCSI terminator. However, termina-  
tion on some external SCSI devices is enabled or disabled by  
setting a switch on the back of the SCSI device.  
By default, termination on the Adaptec SCSI Card 39160 itself  
is set to Automatic (the preferred method). We recommend that  
you do not change this default setting.

other connected SCSI devices are working correctly, please  
contact the manufacturer of the problem device for trouble-  
shooting information.  
Are all SCSI cables and power cables properly connected?  
Are all SCSI devices turned on?  
Have you connected SCSI devices to no more than two of the  
three SCSI Channel A connectors? If you connected devices to  
all three connectors, disconnect devices from one connector!  
Is the Adaptec SCSI Card 39160 firmly seated and secured in  
the PCI expansion slot?  
Is the PCI expansion slot compliant with PCI Rev. 2.1 or higher,  
and does it support Bus Mastering?  
Are all SCSI devices on each SCSI bus assigned unique SCSI  
IDs?  
Are all SCSI devices terminated properly?

Using the Adaptec SCSI  
Card 39160 and SCSI  
Devices  
This section provides useful information on using the Adaptec SCSI  
Card 39160 and your SCSI devices. For more information about a  
specific SCSI device, refer to the documentation for that device.  
Using SCSI Devices  
Caution: Do not connect SCSI devices to more than two of  
the three SCSI Channel A connectors at the same time.  
Using SCSI Hard Disk Drives  
If you connect a SCSI hard disk drive to the Adaptec SCSI Card  
39160 that was previously connected to a different SCSI card,  
you must low-level format the drive before you can use it. Back  
up the data on the drive before you move it! (See Using SCSI  
Disk Utilities on page 24 for information on using the SCSISelect  
format utility.)  
Caution: A low-level format destroys all data on the  
drive. Be sure to back up the data before performing a  
low-level format.  
Every SCSI hard disk drive must be physically low-level for-  
matted, partitioned, and logically formatted before it can be  
used to store data. Most SCSI drives are pre-formatted at the  
factory. If your SCSI hard disk drive has not been pre-format-  
ted at the factory, and if your computer is running under DOS,  
Windows® 3.x, or Windows 95/ 98, you can format the disk  
with the DOS Fdisk and Format commands. (See the DOS and  
Windows documentation for more information.) To format

Using Ultra160 Hard Disk Drives  
We recommend that you connect your LVD (Ultra160 and  
Ultra2) SCSI devices to SCSI Channel B and your non-LVD  
SCSI devices (if any) to SCSI Channel A. This allows the LVD  
SCSI devices to run at their maximum performance levels of  
160 MBytes/ sec or 80 MBytes/ sec. Or you can connect LVD  
SCSI devices to both SCSI channels. If you combine LVD and  
non-LVD SCSI devices on the same SCSI channel, the data  
transfer rate of the LVD SCSI devices will drop down to non-  
LVD SCSI performance levels of up to 40 MBytes/ sec.

internal LVD SCSI cable.  
Using Scanners  
If you connect a scanner to the Adaptec SCSI Card 39160, you must  
install the scanner manufacturer s proprietary software drivers. See  
your scanner s documentation for details.

Using the Adaptec SCSI Card 39160 and SCSI Devices  
Combining SCSI and Non-SCSI Devices  
You can install the Adaptec SCSI Card 39160 in a computer that  
already has a non-SCSI controller, such as an EIDE controller. How-  
ever, you cannot cross-connect the disk drives and other devices:  
SCSI devices must be connected to the Adaptec SCSI Card 39160,  
EIDE devices must be connected to the EIDE controller, and so on.  
When you install the Adaptec SCSI Card 39160 and SCSI disk drives  
in a computer that boots from a non-SCSI disk drive, the computer  
will continue to boot from the non-SCSI disk drive unless you  
change the computers CMOS configuration. You do not need to  
change the configuration if you just want to use the SCSI drives for  
additional file storage space.  
If your computer s motherboard BIOS supports the BIOS Boot Spec-  
ification (BBS) feature, you can select a different boot device without  
much difficulty. (To determine if the motherboard BIOS supports  
BBS, read the computer documentation or contact your mother-  
board manufacturer.)  
The following table shows what to do, after you physically install  
the SCSI card and SCSI devices, to use different kinds of disk drives  
in the same computer:

Adaptec SCSI Card 39160 User’s Reference  
Installing Multiple SCSI Cards  
You can install multiple SCSI cards in your computer; you are  
limited only by the available system resources (for example,  
IRQ settings, I/ O port addresses, BIOS addresses, and so  
forth).  
Each SCSI card you install forms a separate SCSI bus with a  
different set of SCSI devices. SCSI IDs can be reused as long as  
the ID is assigned to a device on a different SCSI card (for  
example, each SCSI card can have a device with SCSI ID 2).  
If you have two or more SCSI cards and your computer boots  
from a SCSI disk drive, leave the host adapter BIOS enabled on  
the SCSI card to which the boot disk drive is connected. Use  
SCSISelect to disable the host adapter BIOS on the other SCSI  
cards.  
Connecting the LED Connector  
(Optional feature) Most computers have an LED disk activity light on  
the front panel of the system case. If you choose to disconnect the  
cable from the LED connector on the motherboard and connect it to  
the LED connector on the SCSI card as shown in the diagram below,  
the LED on the front panel of the computer will light whenever  
there is activity on the SCSI bus.  
Note: If you connect the LED cable to the SCSI card, the LED  
disk activity light will no longer indicate disk activity on the  
non-SCSI disk drives.

Using the Adaptec SCSI Card 39160 and SCSI Devices  
Overriding SCSI Termination Settings  
You use SCSISelect to control the termination of the two SCSI chan-  
nels on the Adaptec SCSI Card 39160. The default termination set-  
ting for both channels is Automatic. This setting allows the SCSI card  
to adjust SCSI termination automatically, depending on which con-  
nectors have SCSI devices attached to them.  
Regardless of the SCSISelect termination setting, the SCSI card termi-  
nation is always disabled when the power is turned off. If you want  
SCSI card termination to be enabled when the power is turned off,  
you must terminate the SCSI channels manually.  
To manually terminate Channel A, place a shunt on jumper J5. To  
manually terminate Channel B, place a shunt on jumper J3. The fol-  
lowing diagram shows where the jumpers are located on the SCSI  
card:  
J3  
J5  
You might want to manually terminate the SCSI card if the Adaptec  
SCSI Card 39160 is connected to one or more external SCSI devices  
that are also connected to a SCSI card in another computer. The  
devices can be shared between the two computers if one SCSI card is  
terminated when it is powered off, while the computer with the  
other SCSI card is using the SCSI devices.

SCSISelect, which is included with the Adaptec SCSI Card 39160,  
enables you to change SCSI settings without opening the computer  
or handling the card. SCSISelect also enables you to low-level format  
or verify the disk media of your SCSI hard disk drives. The follow-  
ing table lists the available and default settings for each SCSISelect  
option. The settings marked as “Auto-sync” are automatically syn-  
chronized for both SCSI channels—for example, if you change the  
Boot Channel option to B First on Channel A, the change will apply  
to Channel B as well. All other options can be set separately for each  
of the two SCSI channels.  
The default settings are appropriate for most systems and should  
not be changed. Run SCSISelect if you need to change or view cur-

gives it the highest priority on the SCSI bus. We recommend  
that you do not change this setting.  
SCSI Parity Checking—(Default: Enabled) When set to  
Enabled, verifies the accuracy of data transfer on the SCSI bus.  
Leave this setting enabled unless any SCSI device connected to  
the Adaptec SCSI Card 39160 does not support SCSI parity.  
Host Adapter SCSI Termination—(Default: Automatic) Deter-  
mines the termination setting for the SCSI card. The default  
setting is Automatic, which allows the SCSI card to adjust the  
termination as needed. We recommend that you do not change  
this setting.  
Boot Device Options  
Boot Channel—(Default: A First) Specifies which of the two  
SCSI channels the boot device is connected to (if the computer  
boots from a SCSI device). If you change this setting, the  
change automatically applies to both SCSI channels.  
Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot  
device. We recommend that you do not change the default  
setting. If you change this setting, the change automatically  
applies to both SCSI channels.  
Boot LUN Number—(Default: 0) Specifies which LUN (Logi-  
cal Unit Number) to boot from on your boot device. This set-  
ting is not valid unless Multiple LUN Support is enabled (see  
setting, the change automatically applies to both SCSI  
channels.

SCSI Device Configuration Options  
SCSI Device Configuration options can be set individually for each  
connected SCSI device.  
Note: To configure settings for a SCSI device, you must  
Sync Transfer Rate—(Default: 160) Determines the maximum  
synchronous data transfer rate that the SCSI card supports. We  
recommend that you leave the maximum (default) value of 160  
MBytes/ sec.  
Initiate Wide Negotiation—(Default: Yes) When set to Yes, the  
SCSI card attempts 16-bit data transfer (wide negotiation).  
When set to No, the SCSI card uses 8-bit data transfer unless  
the SCSI device requests wide negotiation.  
Note: Set Initiate Wide Negotiation to No if you are  
using an 8-bit SCSI device that hangs or exhibits other  
performance problems with 16-bit data transfer rate  
enabled.  
Enable Disconnection—(Default: Yes) When set to Yes, allows  
the SCSI device to disconnect from the SCSI bus. Leave the set-  
ting at Yes if two or more SCSI devices are connected to the  
SCSI card. If only one SCSI device is connected, changing the  
setting to No results in slightly better performance.  
Send Start Unit Command—(Default: Yes) When set to Yes,  
sends the Start Unit Command to the SCSI device at bootup.  
The following three options have no effect if the SCSI Card BIOS is  
disabled. (The SCSI Card BIOS is normally enabled by default.)  
Enable Write Back Cache—(Default: N/C) Can be used to  
enable or disable the write-back cache on SCSI disk drives con-  
nected to the host adapter. Leave this option at its default  
setting of N/ C (no change), which usually allows for optimum  
drive performance.  
20  
 
 
Configuring the Adaptec SCSI Card 39160 with SCSISelect  
BIOS Multiple LUN Support—(Default: No) Leave this set-  
ting at No if the device does not have multiple Logical Unit  
Numbers (LUNs). When set to Yes, the SCSI card BIOS pro-  
vides boot support for a SCSI device with multiple LUNs (for  
example, a CD “juke box” device in which multiple CDs can be  
accessed simultaneously).  
Include in BIOS Scan—(Default: Yes) When set to Yes, the  
SCSI card BIOS includes the device as part of its BIOS scan at  
bootup.  
Advanced Configuration Options  
Note: Do not change the Advanced Configuration Options  
unless absolutely necessary.  
Reset SCSI Bus at IC Initialization—(Default: Enabled) When  
set to Enabled, the SCSI card generates a SCSI bus reset during  
its power-on initialization and after a hard reset.  
Display <Ctrl> <A> Messages during BIOS Initialization—  
(Default: Enabled) When set to Enabled, the SCSI card BIOS  
displays the Press <Ctrl> <A> for SCSISelect (TM) Utility! mes-  
sage on your screen during system bootup. If this setting is dis-  
abled, you can still invoke the SCSISelect Utility by pressing  
<Ctrl> <A> after the SCSI card BIOS banner appears. If you  
change this setting, the change automatically applies to both  
SCSI channels.  
Extended BIOS Translation for DOS Drives > 1 GByte—  
(Default: Enabled) When set to Enabled, provides an extended  
translation scheme for SCSI hard disks with capacities greater  
than 1 GByte. This setting is necessary only for MS-DOS 5.0 or  
above; it is not required for other operating systems, such as  
NetWare or UNIX.  
Caution: Changing the translation scheme destroys all  
data on the drive. Be sure to back up your disk drives  
before changing the translation scheme.  
21  
 
   
Adaptec SCSI Card 39160 User’s Reference  
Use the MS-DOS Fdisk command to partition a disk larger  
than 1 GByte controlled by the SCSI card BIOS, when using  
DOS, Windows 3.1.x, or Windows 95/ 98.  
Verbose/Silent Mode—(Default: Verbose) When set to Verbose,  
the SCSI card BIOS displays the host adapter model on the  
screen during system buildup. When set to Silent, the message  
will not be displayed during bootup. If you change this setting,  
the change automatically applies to both SCSI channels.  
Host Adapter BIOS (Configuration Utility Reserves BIOS  
Space)—(Default: Enabled) Enables or disables the SCSI card  
BIOS. If you change this setting, the change automatically  
applies to both SCSI channels.  
Leave at Enabled to enable the SCSI card BIOS and allow it  
to scan and initialize all SCSI devices.  
Set to Disabled: Not scan if the devices on the SCSI bus (for  
example, CD-ROM drives) are controlled by software driv-  
ers and do not need the BIOS, and you do not want the  
BIOS to scan the SCSI bus.  
Set to Disabled: Scan Bus if you do not need the BIOS, but  
you want it to scan the SCSI devices on the bus and you  
need to spin up the device.  
The following four options have no effect if the SCSI Card BIOS is  
disabled. (The SCSI Card BIOS is normally enabled by default.)  
Domain Validation—(Default: Enabled) Determines the opti-  
mal transfer rate for each device on the SCSI bus and sets  
transfer rates accordingly. Displays the resulting data transfer  
rate. If you change this setting, the change automatically  
applies to both SCSI channels.  
Support Removable Disks Under BIOS as Fixed Disks—  
(Default: Disabled) Determines which removable-media drives  
are supported by the SCSI card BIOS. The options are as  
follows:  
DisabledNo removable-media drives are treated as hard  
disk drives. Software drivers are required because the  
drives are not controlled by the BIOS.  
22  
 
Configuring the Adaptec SCSI Card 39160 with SCSISelect  
Caution: You may lose data if you remove a removable-  
media cartridge from a SCSI drive controlled by the  
SCSI card BIOS while the drive is on. If you want to be  
able to remove the media while the drive is on, install  
the removable-media software driver and set Support  
Removable Disks Under BIOS as Fixed Disks to  
Disabled.  
Boot Only—Only the removable-media drive designated  
as the boot device is treated as a hard disk drive.  
All Disks—All removable-media drives supported by the  
BIOS are treated as hard disk drives.  
BIOS Support for Bootable CD-ROM—(Default: Enabled)  
When set to Enabled, the SCSI card BIOS allows the computer  
to boot from a CD-ROM drive.  
BIOS Support for Int 13 Extensions—(Default: Enabled) When  
set to Enabled, the SCSI card BIOS supports Int 13h extensions  
as required by Plug-and-Play. The setting can be either enabled  
or disabled if your system is not Plug-and-Play.

Using SCSI Disk Utilities  
To access the SCSI disk utilities, follow these steps:  
1
Select the SCSI Disk Utilities option from the menu that  
appears after starting SCSISelect. SCSISelect scans the SCSI bus  
(to determine the devices installed) and displays a list of all  
SCSI IDs and the devices assigned to each ID.  
2
3
Use the and keys to move the cursor to a specific ID and  
device, then press Enter.  
A small menu appears, displaying the options Format Disk  
and Verify Disk Media.  
Format Disk—Allows you to perform a low-level format  
on a hard disk drive. Most SCSI disk devices are preformatted  
at the factory and do not need to be formatted again.  
Caution: A low-level format destroys all data on the  
drive. Be sure to back up your data before performing  
this operation. You cannot abort a low-level format  
once it is started.  
Verify Disk Media—Allows you to scan the media of a  
hard disk drive for defects. If the utility finds bad blocks on  
the media, it prompts you to reassign them; if you select  
yes, those blocks are no longer used. You can press Esc at  
any time to abort the utility.

Connecting SCSI Devices  
Connecting SCSI Devices  
Here are some examples of how you can connect internal and exter-  
nal SCSI devices to the Adaptec SCSI Card 39160. To achieve maxi-  
mum performance, attach the first device to the end connector of the  
cable (furthest from the SCSI card); attach other devices to the con-  
nectors that are closer to the SCSI card.  
The first example shows Ultra160 and Ultra2 SCSI devices con-  
nected to internal and external SCSI connectors of both SCSI  
channels. Note the built-in terminators at the end of the internal  
LVD SCSI cables. The last external SCSI device on each SCSI channel  
must be terminated with an LVD/ SE terminator plug to ensure that  
all devices will operate at their maximum speed.
