Installing the Host Adapter and SCSI
Device
WARNING: Before you start, turn OFF power
to the PC and disconnect the power cord.
Then ground yourself by touching an
unpainted surface of the PC case.
Installing the AVA™-2902I
Step 1: Remove the cover from your PC, following
the manufacturer’s instructions.
Step 2: Find an unused PCI expansion slot in your
PC. Insert the host adapter in the slot, pressing it
down firmly so that the bus contacts are seated in the
slot. (The AVA-2902I does not have a bracket.)
Step 3: Install and mount the internal SCSI device
inside your PC. (See the SCSI device documentation
for instructions on how to install and terminate the
device.)

Step 4: Plug one end of the internal SCSI cable into
the host adapter’s SCSI connector. Be sure the
colored stripe on the cable is aligned with Pin 1 (the ▲
mark) on the connector. The host adapter’s internal
connector is keyed to ensure that the cable is plugged
in correctly.
Step 5: Plug the other end of the cable into the
internal SCSI device. Then connect a DC power cable
from your PC’s power supply to the power input
connector on the internal SCSI device
Step 6: Replace the PC cover, reconnect the power
cord, and turn ON the PC.
Congratulations!You have physically installed the
host adapter and the internal SCSI device. You may
need to install host adapter drivers and other soft-
ware before you can use the device. For more infor-
mation, see the device manufacturer’s instructions
and see Installing Device Drivers on page 4.

Installing the AVA-2902E
Step 1: Remove the cover from your PC, following
the manufacturer’s instructions.
Step 2: Find an empty PCI expansion slot in your
PC. Unscrew the bracket screw and remove the
expansion slot bracket that covers the card-slot
opening.
Step 3: Insert the host adapter in the slot, pressing it
down firmly so that the bus contacts are seated in the
slot. Secure the host adapter bracket with the screw
you removed in Step 2.

Step 4: Plug one end of the external SCSI cable into
the host adapter’s 25-pin external connector and
plug the other end of the cable into either one of the
connectors on the external SCSI device.
Step 5: Enable termination on the external SCSI
device, if necessary. (See the SCSI device
documentation for instructions on how to install and
terminate the device.)
Step6: Replace the PC cover. Connect power cables
to the external device and the PC. Turn ON the
external device, and then turn ON the PC.
Congratulations!You have physically installed the
host adapter and the external SCSI device. You may
need to install host adapter drivers and other soft-
ware before you can use the device. For more infor-
mation, see the device manufacturer’s instructions
and see the next section, Installing Device Drivers.
Installing Device Drivers
■DOS and Windows®3.x do not have embedded
driver support for the AVA-2902E/I host adapter
and your SCSI device. If your PC is running
under DOS or Windows 3.1, you must load these
drivers yourself. If Adaptec’s EZ-SCSI®software
was included with your host adapter, follow the
driver installation instructions in the EZ-SCSI
documentation.

■Windows®95 has embedded driver support for
the AVA-2902E/I host adapter. After you install
the host adapter and reboot your PC, follow the
onscreen instructions to complete the driver
installation.
■Versions 4.0 and 3.51 of Windows NT™have
embedded driver support for the AVA-2902E/I
host adapter. Refer to the operating system docu-
mentation for instructions on loading these driv-
ers. If you have Adaptec EZ-SCSI software or the
Adaptec 7800 Family Manager Set, you can load
an updated version of the Windows NT driver by
following the instructions in the software docu-
mentation.
Technical Tips
■If your host adapter and SCSI device do not seem
to be working properly, check these items first.
– If you have an external SCSI device, did you
turn it ON before you booted the PC?
– Are all SCSI cables and power cables securely
connected?
– Is the host adapter firmly seated in the PCI
slot?
– Is the SCSI device terminated?
■You cannot boot your PC from a SCSI disk drive
connected to the AVA-2902E/I host adapter,
because the host adapter does not have a BIOS.
Your PC must boot from another disk device.
■Does your PC’s CMOS setup require you to
enable PCI bus parameters? If so, refer to the PC
documentation for instructions. Verify that IRQ
channel assignment, board, and BIOS settings
have been made.
Note: Some configuration options apply to a
specific PCI bus slot, so be sure you apply
any option changes to the slot in which the
host adapter is installed. (Check the PC doc-
umentation for more information.)

■Here are some additional CMOS setup issues:
– If there is an Interrupt Type or Interrupt Line
option in the Setup program, select Int-A or
Interrupt Type = A. Depending on your sys-
tem design, you may also need to change a
motherboard jumper setting.
– If there is a Triggering Interrupt option, select
Level.
– If there is an option to enable or disable bus
mastering for the PCI slots, select Enabled.
– If there is an option to enable or disable indi-
vidual PCI slots, be sure the slot in which you
install the host adapter is Enabled.
– If your PC has ISA or EISA boards in addition
to the AVA-2902E/I adapter, you may need to
mark the IRQs used by the ISA/EISA boards
as Used so the system BIOS will not try to
assign these IRQs to PCI boards.
– In some PC systems the BIOS reserves a set of
available IRQs for PCI boards, and you have
to assign these IRQs manually.
