Introduction
NOTE: This installation guide applies to thefollowing QLogic host 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
hostadapterdesignedforhigh-endsystems.Theintelligenceandperformanceare
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 asingle-chip solution.The QLA12160 board supports bootabledevices
(hard disk drivesand CD-ROM drives) and can be used with tape drivesand other
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).
NOTE: Only single-ended and LVD devices (Ultra2 and Ultra3) can be connected
to the QLA12160 board.

Features 1 –Introduction
1-2 DC8151101-00 C
TheQLA12160boardsupportsUltra,Ultra2,and Ultra3transferspeeds.Theboard
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 chaining:
■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 device is connected to the
host adapter board, the second device is connected to the first device, 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.

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. Checkthemotherboard andmake any configuration 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
DeviceConfigurationmenuinthemotherboardsetupBIOSwhereyoumust
enable host adapter boards, bus master slots, and interrupt request (IRQ)
levels. If your motherboard supports triggering, use level triggering for the
QLA12160 board. See the documentation supplied with your computer, or
contactyourcomputerdealertodeterminewhetherornotyourmotherboard
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 supports bus mastering. Most motherboards
automatically assign an IRQ level and interrupt line. If your motherboard
does not, you must assignthe IRQ level and use interrupt line A for this slot.
NOTE:
■Some motherboards have two kinds of PCI bus slots: master
and slave. The QLA12160 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.
❑InstallingaQLA12160/66ina33-MHzslotdoesnotprovide
the board with the performance benefits of a 66-MHz PCI
bus.

10. Power up allexternal SCSI devices, then power upthe PC and observe the
monitor. The BIOS lists all SCSI devices attached to the QLA12160 board.
For example:
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 when troubleshooting or installing other devices.
If there isno hard disk drive attached to your computer, a ROM BIOS NOT
INSTALLED message is displayed after the device listing.
When 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 board in your computer.

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 attached 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

if you have two devices with the same SCSI ID, only one of the devices is listed. If
the BIOS list is not correct, power down the computer and check the configuration.
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 an IDE drive, set the motherboard BIOS parameters to None or
Not Installed. The ROM BIOS on the SCSI controller automatically configures the
SCSI peripherals.
If the QLA12160 board is on a SCSI bus with any single-ended peripheral device,
for example, a CD-ROM, the QLA12160 board automatically operates as a
single-ended,Ultradevice.Consequently,allsingle-endeddevicerestrictionsapply

A.1
Introduction
This appendix provides detailed configurationinformation for advanced userswho
want to customize the configuration of the QLA12160 board and the connected
devices.
TheQLA12160boardisconfiguredatthefactorytoprovidemaximumperformance.
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. To access Fast!UTIL, press ALT+Q
during the QLA12160 board BIOS initialization (it may take a few seconds for the
Fast!UTILmenutoappear).IfyouhavemorethanoneQLA12160board,Fast!UTIL
promptsyoutoselectwhichboardyouwanttoconfigure.Afterchangingthesettings,
Fast!UTIL reboots your system to load the new parameters.
CAUTION! When the configuration settings are incorrect, the QLA12160 board
does not function properly.
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 devices and the QLA12160 board to which they are
attached.

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.
■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 driversstill recognize the QLA12160 board. Do not disable
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 found, the system boots from the first bootable SCSI
drive. When this setting is disabled, the ROM BIOS does not boot from the
CD-ROM. The default is Disabled.
■Adapter Configuration
❑Auto. The ROM BIOS automatically configures the QLA12160 board to
match any SCSI device attached to the board and selects optimum
performance. The default is Auto.
❑Manual. You can controlthe configuration settingsfor each SCSI device
andhavetheoptionofrunningAutoconfigure.See section A.2.4tohave

NOTE: Safe mode is primarily for troubleshooting SCSI devices that
are not functioning properly during normal system operation.
■Drivers Load RISC Code. When this setting is Enabled, the QLA12160
boardusestheRISCfirmwarethatisembeddedinthesoftwaredriver.When
this setting is Disabled, the software driver loads the latest version of RISC
firmware found on the system. The default is Enabled.
NOTE: The driver being loaded must support this setting; otherwise, the
result is the same as Disabled regardless of the setting. Leaving
this option Enabled guarantees a certified combination of software
driver and RISC firmware.
■>4 Gbyte Addressing. Enable this setting when your system has more
than 4 GB of RAM available. The default is Disabled.

SCSI Device Settings
After changing the host adapter settings for the QLA12160 board, 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 Options menu to see the SCSI 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
described in the following paragraphs.

NOTE: These settings apply to each SCSI ID individually.
■DisconnectsOK.WhensettoYes,thedeviceisnotifiedthatitcanoptionally
disconnect from the host adapter. When the drive is ready to continue
executing the command, it must re-establish the link through a reconnect
cycle. When set to No, disconnects are not allowed. The default is Yes.
If you have more than one device attached to the QLA12160 board, set
Disconnects OK to Yes for best performance.
■Check Parity. When set to Yes, odd parity is checked and passed to the
SCSI FIFO when data is received from the SCSI bus. When set to No, the
received SCSI parity is ignored and odd parity is generated for the SCSI
FIFO. The default is Yes.
■Enable LUNs. When set to Yes, multiple LUNs are supported. When set to
No, multiple LUNs are not supported. LUN support is typically required for
CD-ROMchangersorRAIDboxesthatuseLUNstomapdrives.Thedefault
is Yes.
■Enable PPR. When set to Yes, the QLA12160 board attempts to negotiate
forparallelprotocolrequest(PPR)transfers.WhensettoNo,theQLA12160
board does not negotiate for PPR transfers. The default is Yes.
■Enable Device. When set to Yes, the system BIOS recognizes the device
at this SCSI ID. When set to No, the system BIOS ignores the device at this
SCSI ID. The default is Yes.
■Negotiate Wide. When set toYes, the device supports 16-bit, wide (68-pin
cable) SCSI data transfers. When set to No, the device supports only 8-bit
(50-pin cable) SCSI data transfers. The default is Yes.
