Introduction
NOTE: This installation guide appl ies to the followi ng QLogic hos t adapter boards ,
collectively referred to as the QLA12160 board unless otherwise noted:
■ QLA12160/33 (DC8110402-06)
■ QLA12160/66 (DC8110402-07)
The QLA12160 board (wide, low voltage differential [LVD]), dual port,
Ultra3, 64-bit PCI) contains the ISP12160A/33 or ISP12160A/66 chip.
1.1
Product Description
The QLA12160 board is an intelligent, high-performance, DMA bus master SCSI
host adapter design ed for high-end systems. The in telligence and perform ance are
derived from the ISP chip, making the QLA12160 board a high performance host
adapter. The ISP chip combines a powerful RISC processor, two SCSI executive
processors (SXPs), and a peripheral component interconnect (PCI) local bus
interface in a single-chip solution. The QLA12160 boar d supports bootable dev ices
(hard disk drives and CD-ROM dri ves) and can b e used with tape dri ves and ot her
SCSI devices. Installation of the QLA12160 board is quick and easy.
The QLA12160 board is for use only with UL listed computers that have detailed
instructions for user installation of accessory cards.
The QLA12160 board is designed to operate with multiple data transfer speeds
under SCSI specifications (see table 1- 1 ).
Table 1-1. SCSI Data Transfer Rates

DC8151101-00 C 1-1
Features 1 – Introduction
The QLA12160 bo ard supports Ultra, Ultra2, and Ultra3 transfer speeds. The board
can connect computers to other computers or to peripheral devices such as
CD-ROM drives, tape drives, and hard disk drives. SCSI allows connecting the
following numbers and types of devices to a single port by daisy chain ing :
■ 15 fast, wide SCSI devices
■ 15 Ultra2 or Ultra3, LVD SCSI devices
■ 6 Ultra SCSI devices (QLA12160 board in single-ended mode)
A daisy chain is a series of connections where the first devic e is connected to the
host adapter board, the second device is c on nec ted to t he firs t de vi ce, and so on.
A daisy chain can be created either by using a daisy chain cable (one cable with
multiple connectors) or by using multiple cables. Each SCSI device must have a
unique SCSI ID.
Because SCSI allows the computer to use a standard set of commands to
communicate with peripherals, adding a variety of peripherals to your computer
using one host adapter board is easy.

Setting the SCSI Termination
Termination for the QLA12160 board is set automatically in most cases. You can
change the termination using the Fast!UTIL software (see sectionA.2.3).
Termination for the QLA12160 board also can be set using jumpers (see
section B.2).
2.4
SCSI Termination Power
The QLA12160 board s upplies termi nation power to it self and to the SCSI bus. The
circuit is protected by a self-restoring fuse.
2.5
Installing the Device Activity Light
If the SCSI disk is assigned as drive C (boot drive), you can connect the device
activity light on the front pan el of the PC to ind icate boot drive activi ty. Connect the
2-2 BC8151101-00 C
2 – Hardware Installation Installation in the Computer
light to the J9 jumper block on the QLA12160 board (pins1 and 4 are positive). If
your boot drive is an integrated device electronics (IDE) drive or connected to a
different adapter, you can connect an LED to the QLA12160 board jumper blocks
to show activity of devices connected to your QLA12160 board.
2.6
Installation in the Computer
If you changed the termination on the QLA12160 board, double-check the new
setting prior to installation.
Perform the following steps to install the QLA12160 board in your PC:
1. Check the motherb oard and ma ke any config uration changes necessary to
accommodate the QLA12160 board.
The QLA12160 board is self-configuring; however, some motherboards
require manual configuration. For example, some systems have a PCI
Device Configuration menu in the motherboard setup BIOS where you must
enable host ada pte r bo ards , b us m ast er sl ot s , a nd interrupt request (IRQ)
levels. If your motherboa rd supports triggering , us e level triggering for the
QLA12160 board. See th e docu ment atio n su pplie d with you r co mpute r, or
contact your comp uter dealer to determine whether o r not your motherboard
requires configuration.
2. Power down the peripherals, then the computer.
3. Remove the computer cover and save the screws.
4. Choose any PCI bus slot that support s bus m astering . Most m otherboards
automatically assign an IRQ level and interrupt line. If your motherboard
does not, you mus t assign the IRQ level and use i nterrupt line A for this slot.
NOTE:
■ Some motherboards have two kinds of PCI bus slots: master
and slave. The QLA121 60 board must be in a PCI bus master
slot. (Some motherboards share PCI bus master slots with
onboard devices; QLA12160 boards do not work in shared
slots.)
■ If your board is labeled QLA12160/66, it can run in a 66-MHz
PCI slot.
❑ QLogic recommends installing the QLA12160/33 in a
33-MHz PCI slot and the QLA12160/66 in a 66-MHz PCI
slot.
❑ Installing a QLA12160/33 adapter in a 66-MHz PCI slot
forces the entire PCI bus to 33 MHz.
❑ Installing a QLA12160/66 in a 33-MHz slot do es not provide
the board with the performance benefits of a 66-MHz PCI
bus.

the QLA12160 board.
6. Place the QLA12160 board into the slot. Carefull y press the bo ard into the
slot until it seats firmly.
NOTE: QLA12160 boards are designed with the components on the
opposite side compared with non-PCI boards.
7. Secure the QLA12160 board with the slot cover screw.
8. Install the cable.
❑ Internal: Connect the cable from th e devices to th e J3 connec tor on the
QLA12160 board.
❑ External: Connect a SCSI cable from the devices to the J1 connector
and/or the J2 connector.
NOTE: If you are attaching an exte rnal device , you must provide you r own
cable.
9. Carefully reinst all the computer cover . Insert and tighten the compu ter cover
screws.
10. Power up all ex ternal SCSI device s, then powe r up the PC and ob serve the
monitor . The BI OS list s all SCSI devices at tached to the Q LA12160 board .

2 – Hardware Installation Installation Help
See the Software Installation Guide for the QLA12160 Board on the QLogic web
site http://www .qlogic.com/ for detailed i nstructions on h ow to install the Q LA12160
board’s software drivers.
If the information displayed on your monitor is not correct and you have checked
the QLA12160 bo ard’s confi guration, see section 3 for troubleshooting informa tion.
2.7
Installation Help
If your system has an IDE fixed disk device, be sure to program the system BIOS
to point to the appropriate boot drive. If your system does not have an IDE disk
device, the first boot able SCSI disk device confi gured (the one with the lowest SCSI
ID) is assigned device number 80 and is the boot device.
For a motherboard BIOS that does not support SCSI disk booting, you can use
settings in Fast!UTIL to select the system’s boot device attach ed to the QLA12160
board. If the boot device is a CD-ROM, see the CDROM boot setting in table A-1.
If the boot device is a disk, see section A. 2.5 about selectable boot settings.
SCSI ID numbers must be unique; otherwise, the BIOS list of SCSI devices
displayed on your mo nitor is not correct. For example, if you give one of your devices
the same SCSI ID as th e QLA12160 b oard, that device i s listed for all SCSI I Ds; or
if you have two devic es with t he sam e SCSI ID, o nly one of the de vices is listed . If
the BIOS list is not corre ct, pow er down th e comp uter an d chec k the conf igurati on.
Be sure to check the QLA12160 board, which uses SCSI ID 7. If you do not see
your device listed on the BIOS listing, see section 3.
If you do not have a n IDE driv e, set th e motherb oard BIO S par ameters to None or
Not Installed. The R OM B IOS on the SCSI controller automaticall y configures the
SCSI peripherals.
If the QLA12160 bo ard is on a SCSI bus w it h an y si ngle-ended peripheral d evi ce,
for example, a CD-ROM, the QLA12160 board automatically operates as a
single-ended, Ultra dev ice. Consequently , all single-ended de vice restrictions apply
to the QLA12160 board, even though it is an LVD device (see table 3-1 and
appendix C).

Introduction
This appendix p rovides d etaile d configu ration informati on for adva nced use rs who
want to customize the configuration of the QLA12160 board and the connected
devices.
The QLA12160 bo ard is configured at the f actory to provide maximum performance.
When your board is operating at maximum performance, it may not be 100%
compatible w ith some o lder SCSI-1devices. If you are using a SCSI-1 device, see
section A.5 for more information.
The board can be confi gured usin g Fast!UTIL. To access Fast!UTIL , press ALT+Q
during the QLA12160 board BIOS initialization (it may take a few seconds for the
Fast!UTIL menu to appear). If you have more than one Q LA12160 board, Fast!UTIL
prompts you to se lect which board you want to conf igure. After changing the settings,
Fast!UTIL reboots your system to load the new parameters.
CAUTION!
The following sections describe the Fast!UTIL options.
A.2
Configuration Settings
The first selection on the Fast!UTIL Options menu is Configuration Settings.
These settings configure SCSI d evices an d the QL A12160 bo ard to which they are
attached.
When the configuration settings are incorrect, the QLA12160 board
does not function properly.
DC8151101-00 C A-1
Configuration Settings A – Fast!UTIL
A.2.1
Host Adapter Settings
From the Configuration Settings menu in Fast!UTIL, select Host Adapter
Settings. Default settings for the QLA12160 host adapter board are listed in
table A-1 and described in the following paragraphs.
Table A-1. Host Adapter Settings
Setting Options Default

PCI bus DMA burst Enabled, Disabled Enabled
CDROM Boot Enabled, Disabled Disabled
Adapter Configuration Auto, Manual, Safe Auto
Drivers load RISC code Enabled, Disabled Enabled
>4 Gbyte Addressing Enabled, Disabled Disabled
Fast Command Posting Enabled, Disabled Enabled
■ Host adapter BIOS. When this setting is Disabled, the ROM BIOS on the
QLA12160 board is disabled, freeing space in upper memory. The RAM
BIOS and other drivers still rec ognize the Q LA12160 boa rd. Do not d isable
this setting when you are booting from a SCSI disk drive attached to the
QLA12160 board. The default is Enabled (ROM BIOS on the QLA12160
board is enabled).
■ PCI bus DMA burst. When this setting is Enabled, burst transfers are
performed. When this setting is Disabled, data is transferred in nonburst
mode, with each cycle initiated by a new address phase. The default is
Enabled.
■ CDROM Boot. When this setting is Enabled, the ROM BIOS boots from the
attached SCSI CD-ROM when a bootable compact disk is installed. If no
bootable CD-ROM is fou nd , the sy st em boots from the first bootable SCSI
drive. When this se tting i s disa bled, th e ROM BI OS does not bo ot from th e
CD-ROM. The default is Disabled.
■ Adapter Configuration
❑ Auto. The ROM BIOS automatica lly configure s the QLA121 60 board to

SCSI Device Settings
After changing the host adapter settings fo r th e Q LA1 216 0 b oard, you can modify
device parameters for SCSI devices connected to the board. From the
Configuration Settings menu in Fast!UTIL, select SCSI Device Settings. The
settings are linked to the device’s SCSI ID (0–15). If you make changes, be sure
that the SCSI ID matches the settings of the device you want to change. Select
Scan SCSI Bus from the Fast!UTIL O ptions menu to see the SC SI IDs assigned
on your system (see section A.3) .
NOTE: The Adapter Configuration setting in the Host Adapter Settings (see
section A.2.1) controls which device settings you can change.
The options and defaults for SCSI device settings are listed in table A-2 and

■ SCSI termination
Termination for the QLA12160 board can be set in one of three ways:
❑ Automatic (default)
❑ Manual (through Fast!UTIL)
❑ Jumpers
NOTE: The last SCSI device on each end of the SCSI bus must be
terminated.
The QLA12160 board is a dual-port host adapter. Each port is a separate
SCSI bus and must be terminated independently. The port one and two
connectors are listed in table A-4.
Table A-4. QLA12160 Ports
Port
One J1 and J3
Two J2
QLA12160 Port
Connector
The following text explains automatic and manual termination. See
section B.2 for jumper termination instructions.
❑ Auto. SCSI termination requirements are sensed by the board and set
automatically. The default is Auto.
With QLA12160 boards, th e Auto setting assumes th at port one is at one
end of the SCSI bus and enables termination for port one. If you are
using a single port-one connector, the Auto setting assumes that port
one is at the end of the SCSI bus an d enab les term inati on for po rt one.
If you have devices connected to both port one connectors , the Auto
setting disables termination for port one.
❑ Enabled. This setting overrides termination requ irements sen sed by the
board, assumes that the selected port is at one end of the SCSI bus,
and enables termination.
❑ Disabled. SCSI termination is disabled. This setting overrides
termination requirements sensed by the board. Use this setting when J1,
J2, or J3 is not at one end of the SCSI bus. For example, use this setting
when you have wide devices daisy chained to the QLA12160 J1, J2,
or J3 connector with a sing le cable and the J1, J2, or J3 connector is not
at the end of the cable.
❑ High Only . High termination is enabled . This setting overrides termination
requirements sensed by the board.
Use this setting for the QLA1216 0 board’s port one (J1 or J3) w hen you
have a wide device connected to one connector and a narrow device
A-6 DC8151101-00 C
A – Fast!UTIL Configuration Settings
connected to the other connector. Use this setting for the QLA12160
board’s port two (J2) when the port two connector is not at one end of
the SCSI bus and you have narrow devices at one end of the bus and
wide devices at the other end.
A.2.4
Autoconfigure SCSI Devices
NOTE: You must set the Adapter Configuration setting in Host Adapter Settings
The QLA12160 board is designed to sense and configure the devices connected
to your board. When Adapter Configuration is set to Manual, the Autoconfigure
option allows you to control when the bus is scanned and configured. Select the
Autoconfigure SCSI Devices option from the Configuration Settings me nu to
scan devices on the SC SI bus. Set t he follow ing option s, based on the capab ilities
of each device:
to Manual (see secti on A.2.1) to use Autoconfigure; ot herwise, all changes
made with Autoconfigure are reset when your system is rebooted.
■ Disconnects
■ Enable LUN Support
■ Enable PPR
■ Enable Device
■ Negotiate Wide
■ Negotiate Synchronous
■ Tagged Queuing
■ Sync Period
The settings are displayed in the SCSI Device Settings window. Use the arrow
keys to change settings . See section A.2.2 for more information about SCSI Device
Settings and see sectionA.2.1 for Host Adapter Settings.
If you use Autoconfigure to configure your system, run Fast!UTIL and selec t
Autoconfigure SCSI Devices after addi ng or reconfiguring devices atta ched to the
QLA12160 board.
A.2.5
Selectable Boot Settings
The Selectable Boot Settings option i s accessed from the Configuration Settings
menu. When this option is Enabl ed, you can s elect the SCSI ID (0–15) from which
you want to boot. Once enabled, this option forces the system to boot o n the selected
SCSI drive, ignoring any IDE drives attached to your system. When this option is
Disabled, the system loo ks for an IDE drive from which to boot. When an IDE drive
is not found, the system loo ks for the first bo otable SCSI drive. Wh en this option is
disabled, SCSI Boot ID and SCSI Boot LUN parameters have no effect.
NOTE: This option applies only to disk devices, not to CD-ROMs, tape drives, or

A.5
Using SCSI-1 Devices
The QLA12160 board is configured at the factory with default parameters that
provide maximum performance. When the board is operating at maximum
performance, it may not be 100% compatible with some older SCSI-1 devices.
If the SCSI-1 device attached to the QLA12160 board is not functioning correctly,
you can turn off some high-perf ormance paramet ers for maximum compatibility.
Follow these steps:
1. When you power up the system, press CTRL+Q to access Fast!UTIL.
2. Select Configuration Settings from the Fast!UTIL Options menu.

SCSI Termination
B.1
Setting the SCSI Termination
The first and last physical SCSI devices on each end of the SCSI bus must be
terminated.
Termination is set automatically through Fast!UTIL (see section A.2.1). The
QLA12160 board offers the additional option of terminating with jumpers (see
section B.2).
Some cables h ave multip le connectors for connecti ng several devices to one of the
board’s connectors. If the board uses a connector that is not on either end of the
cable, then the board is not at one end of the SCSI bus and you need to change
the termination setting .
The following sections describe how to set termination for the QLA12160 board.
The text and illustrati ons describe multiple SCSI devices dais y chained onto a single
connector on the board. When daisy chaining narrow and wide SCSI devices,
always have a wide SCSI device at the end of the chain.
NOTE: QLogic recommends using external termination in system configurations
with multiple initiato rs that share the sa me SCSI bus (su ch as in Micro soft
cluster configurations). External termination ensures proper device
operation during power cycles. When external termination cannot be
provided, termi nat e all h os t b us a dapters using jum pers ( see se ctionB.2).
B.2
Termination (Jumpers) for the QLA12160
The QLA12160 board comes from the factory with jumpers on pins 1–2 of J5, J6,
J7, and J8; these settings allow automatic termination (see section A.2.1).
Moving the jumpers on J5 and J6 on the QLA12160 board manually sets the
termination for port on e. Moving the jumpers on J7 and J8 on the QLA12160 board
manually sets the termination for port two (see figure B-1). Settings made with these
jumpers override all Fast!UTIL or automatic termination settings.
