The QLA12160/12160L 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 QLA12160/12160L board is an intelligent, high-performance, DMA bus
master SCSI host adapter designed for high-end systems. The intelligence and
performance are derived from theISP chip, makingthe QLA12160/12160L 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
QLA12160/12160L board supports bootable devices (hard drives and CD-ROM
drives) and can be used with tape drives and other SCSI devices. Installation ofthe
QLA12160/12160L board is quick and easy.
The QLA12160/12160L board is for use only with UL listed computers that have
detailed instructions for user installation of accessory cards.
The QLA12160/12160L board is designed to operate with multiple data transfer
speeds under SCSI specifications (see table 1-1).

NOTE: Onlysingle-endedandLVDdevices(Ultra2andUltra3)canbeconnected
to the QLA12160/12160L board.
The QLA12160/12160L board supports Ultra, Ultra2, and Ultra3 transfer speeds.
The boardcan connect computersto other computersor to peripheral devices such
as CD-ROM drives, tape drives, and hard drives. SCSI allows connecting the
following number and type of devices to a single port by daisy chaining:
❑15 fast, wide SCSI devices
❑15 Ultra2 or Ultra3, LVD SCSI devices
❑6 Ultra SCSI devices (QLA12160/12160L board in single-ended mode)
A daisy chain is a series of connections where the first device is connected to the
host adapter board, the second device is connected to the first, and so on. A daisy
chain can be created by using either 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.

2.3
Setting the SCSI Termination
Termination for the QLA12160/12160L board is set automatically in most cases.
You can change the termination using the Fast!UTIL software (see section A.2.1).
Termination for the QLA12160/12160L board can also be set using jumpers (see
section B.2).
2.4
SCSI Termination Power
TheQLA12160/12160Lboardsupplies terminationpowertoitselfandto theSCSI
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 panel of the PC to indicate boot drive activity. Connect
the light to the J9jumper block on the QLA12160 or J1 onthe QLA12160L (pins 1
and 4 are positive). If your boot drive is an integrated drive electronics (IDE) drive
or connected to a different adapter, you can connect an LED to the
QLA12160/12160L jumper blocks to show activity of devices connected to your
QLA12160/12160L board.
2.6
Installation in the Computer
Ifyouchangedtheterminationon theQLA12160/12160Lboard,double-checkthe
new setting prior to installation.
Perform the following steps to install the QLA12160/12160L board in your PC:
1. Check the motherboard and make any configuration changes necessary to
accommodate the QLA12160/12160L board.
The QLA12160/12160L 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 adapter boards, bus master slots, and interrupt
request (IRQ) levels. If the motherboard supports triggering, use level
triggering for the QLA12160/12160L board. See the documentation
suppliedwithyourcomputer,orcontactyourcomputerdealertodetermine
if your motherboard requires configuration.
2. Power down the peripherals, then the computer.
3. Remove the computer cover and save the screws.

Installation in the Computer 2 –Hardware Installation
2-4 DC8151101-00 B
4. Choose any PCI bus slot that supports bus mastering. Most motherboards
automatically assign an IRQ level and interrupt line. If your motherboard
doesnot, youmustassigntheIRQ level and useinterruptlineAforthisslot.
NOTE:
❑Some motherboards have two kinds of PCI bus slots: master and slave.
The QLA12160/12160L board must be ina PCI busmaster slot. (Some
motherboards share PCI bus master slots with onboard devices.
QLA12160/12160L boards do not work in shared slots.)
❑If your board is labeled QLA12160/66 or QLA12160L/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 or QLA12160L/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 or QLA12160L/66 in a 33-MHz slot does
not provide the board with the performance benefits of a 66-MHz
PCI bus.
5. Unscrew and remove the slot cover. Retain the screw; you will use it when
you install the QLA12160/12160L board.
6. PlacetheQLA12160/12160Lboardintothe slot.Carefullypress theboard
into the slot until it seats firmly.
NOTE: QLA12160/12160L boards are designed with the components on
the opposite side compared to non-PCI boards.
7. Secure the QLA12160/12160L board with the slot cover screw.
8. Install the cable.
❑Internal: Connect the cable from the devices to the J3 connector on the
QLA12160/12160L board.
❑External: Connect a SCSI cable from the devices to the J1 connector
(QLA12160) and/or the J2 connector (QLA12160/12160L).
NOTE: If you are attaching an external device, you must provide your
own cable.

9. Carefully reinstall the computer cover. Insert and tighten the computer
cover screws.
10. Power up all external SCSI devices, then powerup the PC and observe the
monitor. The BIOS lists all SCSI devices attached to the
QLA12160/12160L board. For example:
It is a good idea to write down and store the SCSI device information for
future use. You can access the same information using Fast!UTIL (see
appendix A). This information is helpful for troubleshooting or when you
install other devices.
If you don’t have a hard drive attached to your computer, a ROM BIOS
NOT INSTALLED message displays after the device listing.
If the information displayed on your monitor is correct (all installed devices are
listed with the correct SCSI ID, device type, etc.), congratulations! You have
successfully installed the QLA12160/12160L board in your computer.
SeetheSoftware Installation Guide for theQLA12160/12160Lon the QLogic web
site http://www.qlogic.com/ for detailed instructions on how to install the
QLA12160/12160L board’s software drivers.
If the information displayed is not correct and you have checked the
QLA12160/12160L board’s configuration, see section 3 for troubleshooting
information.

SCSI ID numbers must be unique. If not, the BIOS list of SCSI devices displayed
on your monitor will not be correct. For example, if you give one of your devices
the same SCSI ID as the QLA12160/12160L board, that device will be listed for
all SCSI IDs, or if you have two devices with the same SCSI ID, only one of the
devices will be listed. If the BIOS list is not correct, power down the computer and
recheck the configuration. Be sure to check the QLA12160/12160L board, which
uses SCSI ID 7. If you do not see your device listed on the BIOS listing, see
section 3.

SCSI Problem Checklist
❑Make sure that the SCSI bus termination for the QLA12160/12160L board
is set correctly (see appendices A and B).
❑Make sure that the termination for all devices on the SCSI bus is set
correctly.
❑Were all of the SCSI devices powered up before you powered up the PC?
❑Does each device have a unique SCSI ID? Each device must have its own
unique IDbetween 0 and 15. The QLA12160/12160L board is set for SCSI
ID 7 at the factory.
❑Check the cable lengths. Make sure that the total length for the cables
connected to the QLA12160/12160L board don’t exceed the limits listed
in table 3-1.

Introduction
Thisappendix providesdetailedconfigurationinformationforadvanceduserswho
want to customize the configuration of the QLA12160/12160L board and the
connected devices.
The QLA12160/12160L board is configured at the factory to provide maximum
performance. When your board is operating at maximum performance, it may not
be 100% compatible with some older SCSI-1 devices. If you are using a SCSI-1
device, see section A.5 for more information.
The board can be configured using Fast!UTIL. Access Fast!UTIL by pressing
<ALT>-<Q>duringtheQLA12160/12160L boardBIOSinitialization(itmaytake
a few seconds for the Fast!UTIL menu to appear). If you have more than one
QLA12160/12160L board, Fast!UTIL asks you to select the board you want to
configure. After changing the settings, Fast!UTIL reboots your system to load the
new parameters.
CAUTION! If the configuration settings are incorrect, your QLA12160/12160L
board will not function properly.
The following sections describe the Fast!UTIL options.

The default settings for the QLA12160/12160L host adapter board are listed in
table A-1 and described in the following paragraphs.
❑Host adapter. When this setting is enabled, the system BIOS and drivers
recognize theQLA12160/12160L board. When this setting is disabled, the
BIOS and drivers ignore the board. The default is Enabled.
❑Host adapter BIOS. When this setting is disabled, the ROM BIOS on the
QLA12160/12160L board is disabled, freeing space in upper memory. The
