The AHA-2910Bi host adapter provides a powerful multitasking inter-
face between your computer’s PCI bus and internal SCSI devices (disk
drives, CD-ROM drives, tape drives, removable-media drives, etc.).
The host adapter supports the SCAM (SCSI Configured AutoMati-
cally) protocol, which automatically assigns SCSI IDs to SCAM com-
patible devices. The following figure shows the major components of
the 2910Bi host adapter.
Adaptec’s software drivers enable you to use AHA-2910Bi host adapt-
ers in computers running DOS/Windows®, OS/2, Windows 95,
MacOS, Windows NT™, UNIX, and NetWare.

Installation
WARNING: Before beginning the installation,
turn OFF power to the computer and peripheral
devices and disconnect the power cords.
Step 1: Remove the cover from the computer case.
(If necessary, refer to your computer documentation.)
Step 2: Locate an unused PCI expansion slot. (This
slot is typically white or ivory.) Unscrew the
expansion slot bracket that covers the card-slot
opening.
The PCI slot must support 5-volt Bus Master data trans-
fers (refer to your computer documentation or contact
your vendor).
Step 3: Insert the host adapter in the PCI expansion
slot. Press it down firmly so that the contacts are
securely seated in the slot and secure it with the
screw that you removed in step 2.
Step 4: OPTIONAL-Connect the host adapter to
the LED on the computer so that it will light
whenever there is activity on the SCSI bus. To do this
disconnect the LED cable from the LED connector on
the motherboard and connect it to the LED connector
on the host adapter.

Step 5: Make sure that all SCSI devices have
unique SCSI ID’s from 0 to 6. (Refer to your device
documentation for SCSI ID settings and instructions
on manually changing the default settings.)
Caution: AHA-2910Bi host adapters support
only single-ended SCSI devices. Differential SCSI
devices may be damaged if you connect them to
the host adapter. Most SCSI devices are single-
ended. Read the device documentation.
Step 6: Install or enable terminators on the device
that you plan to installat the end of the internalcable.
Then remove or disable terminators on all remaining
devices. However, never terminate more than two
devices on the SCSI bus. The AHA-2910Bi detects
installed SCSI devices on the bus and sets its own
termination automatically.
WARNING: If you decide to attach your host
adapter between two terminating SCSI devices
on the internal SCSI connector, you must disable
host adapter SCSI termination using the
SCSISelect utility that comes with the
AHA-2910Bi product.
On most internal SCSI devices, you control termination
by setting a jumper or a switch, or by physically remov-
ing or installing a resistor module(s).
Refer to the device’s documentation to determine how to
enable or disable termination on your particular device.
Step 7: Install and mount each internal SCSI device
inside your computer. (Refer to your computer and
device documentation for instructions.)
If you purchased your AHA-2910Bi as part of an
Adaptec kit, the kit includes one 50-pin internal SCSI
cable that allows you to connect up to two internal SCSI
devices.
Step 8: Plug one end of your 50-pin internal SCSI
cable into the host adapter’s internal SCSI connector.
To connect more than two internal devices, use a
SCSI cable with enough connectors to accommodate
all of your devices.

Make sure that the colored stripe on one side of the cable
is aligned with pin-1 of the host adapter’s connector.
Pin-1 of the connector is usually designated by a small
triangle (▲), or a “1” on the connector.
Step 9: Plug the other end of the 50-pin internal
SCSI cable into one of the connectors on the last
internal SCSI device in the chain. This device must be
terminated. Make sure the colored stripe on the side
of the cable is aligned with pin-1 of the SCSI device’s
connector.
Step 10: Plug the remaining cable connectors into
any remaining internal devices. These devices must
not be terminated.
Step 11: Connect a DC power cable from your
computer’s power supply to the power connector on
the SCSI device.
Step 12: Replace the computer chassis cover.
Step 13: Reconnect the power cables to your
computer and peripherals, turn on your external
SCSI devices, and then turn on your computer.
Step 14: If your system CMOS setup requires you
to enable PCI bus parameters, do so now.
Note: The PCI bus usually assigns IRQs and I/O
port addresses automatically. However, in some
cases you may need to manually edit the PCI
bus parameters in your CMOS setup. See your
computer documentation.

Step15:Install the appropriate host adapter device
driver for your operating system.
■DOS and Windows 3.x: DOS and Windows 3.x does
not have embedded driver support for your
AHA-2910Bi product, so you must load them your-
self. If your host adapter came with Adaptec’s
EZ-SCSI®software, see the EZ-SCSI software docu-
mentation for driver installation instructions.
■Windows 95: To verify that your AHA-2910Bi device
driver has been properly installed under Windows
95, see Windows 95 Driver Installation on page 7.
Note: After installing your AHA-2910Bi product
and restarting Windows 95, the system prompts
you through the rest of the installation.
■Windows NT: Windows NT 4.0 has embedded driver
support for the Adaptec AHA-2910Bi product. How-
ever, earlier versions of Windows NT do not have embed-
ded driver support, so you must load the driver yourself.
If your AHA-2910Bi came with Adaptec EZ-SCSI
software (v4.01 or later), install the Windows NT
driver from the diskette provided for your
AHA-2910Bi to support previous versions of Win-
dows NT. (Refer to the Adaptec EZ-SCSI documenta-
tion.) Otherwise, if your host adapter came with
Adaptec’s 7800 Family Manager Set software (v1.3),
see the 7800 Family Manager Set software documen-
tation for driver installation instructions.
■MacOS: MacOS does not have embedded driver sup-
port for the AHA-2910Bi product, so you must install
the Mac driver yourself using the diskette provided
with your AHA-2910Bi.
■NetWare, OS/2, and UNIX: Drivers for these operat-
ing systems are not embedded, so you must load
them yourself. If your host adapter came bundled
with Adaptec’s 7800 Family Manager Set software
(v1.3), see the 7800 Family Manager Set software doc-
umentation for driver installation instructions.
Note: If you purchasedyour host adapter from a
third-party vendor, you can use the drivers they
provide. (Refer to the third-party documenta-
tion for installation instructions and problem
resolution.) To obtain any of the Adaptec device
drivers, contact Adaptec directly.
Congratulations!You have completed the
installation of your host adapter. For additional informa-
tion on configuring your host adapter, see Helpful Hints.

Helpful Hints
This section contains useful information on configuring
and using your host adapter.
Configuring SCSI Devices
Your host adapter can transfer data up to 10 MBytes/sec
when connected to devices that support Fast SCSI. SCSI
devices can coexist on the same cable and each will
transfer data at its own negotiated or assigned transfer
rate. However, in order to reliably transfer data at the
transfer rate of Fast SCSI, the following requirements
must be met:
■The internal cable must be terminated with an active
terminator, either provided by the SCSI device at the
end of the cable or by a separate terminating plug.
The terminator on the AHA-2910Bi is an active termi-
nator.
■Be sure to use a high-quality internal SCSI cable to
ensure reliable data transfer for SCSI devices con-
nected to the host adapter.
Note: Cables with a 25-pin DB-25 style connec-
tor will affect automatic termination (see Host
Adapter SCSI Termination on page 8). Always
leave parity checking enabled to verify reliable
data transfers.
■When one or more Fast SCSI devices are connected to
the host adapter, the combined length of all cables
must not exceed 3 meters (9.8 feet) to ensure reliable
operation and data transfers of up to 10 MBytes/sec.
■Your host adapter can support the SCSI Configured
AutoMatically (SCAM) protocol, which automati-
cally assigns SCSI IDs dynamically and resolves SCSI
ID conflicts. To enable or disable SCAM support, see
Advanced Configuration Options on page 9.
Configuring Disk Drives
■The AHA-2910Bi product does not support the boot
option. To boot your system, use an IDE board or a
second SCSI host adapter with boot capabilities.
■Every SCSI hard disk must be physically low-level
formatted, partitioned, and logically formatted before
you can use it to store data. SCSI hard disks are phys-
ically formatted at the factory and do not need to be
physically formatted again.
If you connected a new SCSI hard disk drive to your
host adapter, you must partition and logically format
the drive. For DOS and Windows (3.x and 95) use the
AFDISK and FORMAT commands (see your com-
puter and DOS documentation). For other operating
systems, see your operating system documentation.
Installing Multiple Adapters
■You can install multiple SCSI host adapters if the sys-
tem resources are available (e.g., I/O port must be
unique).
■Each host adapter you install forms a separate SCSI
bus with a different set of SCSI devices.
■SCSI IDs can be reused as long as a unique ID is
assigned to a device on a different host adapter (e.g.,
each host adapter can have a device with SCSI ID 0).

Windows 95 Driver Installation
To make sure that your AHA-2910Bi driver software has
been properly installed and is operating under
Windows 95, do the following:
1On the Win95 desktop press Start. An options menu
appears.
2On the options menu click on Setting and select Con-
trol Panel.
3Click on System. The System Properties window
appears.
4Click on Device Manager.
5Click on the SCSI Controllers icon.
6If the Adaptec AIC-7850 PCI SCSI Controller is not
listed, follow the instructions in the EZ-SCSI or the
7800 Family Manager Set documentation for install-
ing driver support.
OR
If you see a yellow exclamation point or red Xin front
of the listing for the AIC-7850 Controller, double click
on the icon to see the error message and correct the
problem.
Using SCSISelect
The SCSISelect configuration utility allows you to change
host adapter settings without opening the computer
case. SCSISelect also contains SCSI disk utilities that
allow you to perform a low-level format or verify the
disk media of your SCSI hard disk drives.
Starting the SCSISelect Utility
Use the bootable floppy diskette that is included with
your AHA-2910Bi product. After starting your computer
and inserting the floppy diskette, the first menu that
appears displays the options for SCSI Configuration set-
tings and the SCSI Disk Utility. At this time you may
select either a color or monochrome display by pressing
F5 (this feature may not work on all monitors).
Using SCSISelect Menus
SCSISelect uses menus to list the options you can select.
To select an option, use either the tab key or the up/
down arrow keys to move the cursor. Then press Enter.
When you select an option by pressing Enter, the system
may display an additional options menu. Return to the
previous menu at any time by pressing Esc. To restore
the original SCSISelect default values, press F6.
Exiting SCSISelect
To exit SCSISelect, press Esc until a message prompts
you to exit (if you changed any host adapter settings,
you are prompted to save the changes before you exit).
At the prompt, select Yes to exit, then press any key to
reboot the computer. Any changes you made in
SCSISelect take effect after the computer boots.
Default Settings

Definitions of SCSISelect Settings
This section defines the SCSI device settings for the host
adapter and for each device on the SCSI bus.
SCSI Bus Interface Definitions
The following definitions are most likely to require
modification.
■Host Adapter SCSI ID—This option sets the SCSI ID
of the host adapter.
To give the host adapter the highest priority on the
SCSI bus, we recommend that you leave the host
adapter at its default setting of SCSI ID 7.
■SCSI Parity Checking—This option determines
whether the host adapter verifies the accuracy of data
transferred on the SCSI bus. The default setting is
Enabled.
If any SCSI device connected to the host adapter does
not support SCSI parity, disable SCSI Parity Checking
on the host adapter and all SCSI devices. To deter-
mine if a device supports SCSI parity, consult the
device documentation.
■Host Adapter SCSI Termination—This option sets
termination on the host adapter. You can set termina-
tion to Automatic, Enabled, or Disabled. In general, you
should leave this option set to its default setting of
Enabled.
SCSI Device Configuration Settings
SCSI device configuration settingsallow you to configure
parameters for each device on the SCSI bus. To configure
a specific device, you must identify the SCSI ID assigned
to that device. To determine the SCSI ID of a device, see
Using the SCSI Disk Utilities on page 9.
■Initiate Sync Negotiation—This option determines
whether synchronous data transfer negotiation
between the host adapter and a device is initiated by
the host adapter.
The default setting is Yes (Enabled). Set Initiate Sync
Negotiation to No for devices that do not support
Sync Negotiation.
■Maximum Sync Transfer Rate—This option sets the
maximum synchronous data transfer rate that the
host adapter supports. The host adapter supports
rates up to 10 MBytes/sec.
If Initiate Sync Negotiation is set to No, then the max-
imum synchronous transfer rate is the maximum rate
that the host adapter accepts from the device during
negotiation.
■Enable Disconnection—This option lets a SCSI
device temporarily disconnect the SCSI device from
the SCSI bus. This allows the host adapter to perform
other operations while the SCSI device is discon-
nected. The default setting is Yes. Set Enable Discon-
nection to Yes if two or more SCSI devices are
connected to the host adapter.
Advanced Configuration Options
Plug and Play SCAM Support—Only Windows 95 sup-
ports this option. This option allows the host adapter to
automatically assign SCSI IDs to SCSI devices that sup-
port the SCAM protocol.
Caution: The default setting is Disabled. Most
non-SCAM legacy devices tolerate the SCAM
protocol, so you can enable this option even if
you have a non-SCAM device.

Using the SCSI Disk Utilities
To access the SCSI disk utilities, select the SCSI Disk
Utilities option from the menu that appears after start-
ing SCSISelect.
Once the option is selected, SCSISelect immediately scans
the SCSI bus and displays a list of all SCSI IDs and the
devices assigned to each ID. When you select a specific
ID and device, a menu appears, displaying the options
Format Disk and Verify Disk Media.
■Format Disk—This utility 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.
The Adaptec Format Disk utility is compatible with
the vast majority of SCSI disk drives.
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—This utility 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
■Board Control—Use Board Control to configure the
AHA-2910Bi for Power Macintosh PCI systems. For
instructions, see the documentation included on the
Board Control diskette.
Troubleshooting Checklist
If you have any problems during the installation, check
the following items first:
■Have you installed the host adapter into a PCI Rev
2.0 compliant computer?
■Are all SCSI devices powered?
■Are all SCSI bus cables and power cables properly
connected? Is pin 1 oriented correctly?
■Does the host adapter and each device on the SCSI
bus have a unique SCSI ID?
■Did you install your host adapter in a bus master PCI
slot? Refer to your computer’s documentation for
instructions or try another slot.
■Are all devices on the SCSI bus terminated properly?
■Does your system CMOS setup require you to enable
PCI bus parameters? If so, refer to your computer’s
documentation for instructions. Check that IRQ chan-
nel assignment, board, and BIOS settings have been
made.
Some configuration options apply to a specific PCI
bus slot, so if you change these options be sure you
are applying them to the slot in which the host
adapter is installed.
Check your computer documentation to verify which
slot corresponds to which number.
– If there is an Interrupt Type or Interrupt Line
option in the Setup program, be sure to select
Int-A or Interrupt Type = A. Depending on your
system design, you may also be required to
change a motherboard jumper setting.
– If there is a Triggering Interrupt option, be sure to
select Level.
– If there is an option to enable or disable bus mas-
tering for the PCI slots, be sure to select Enabled.
– If there is an option to enable or disable individ-
ual PCI slots, be sure the slot in which you install
the host adapter is Enabled.

– If your computer has a combination of ISA (or
EISA) boards and PCI boards, you may need to
mark the IRQs used by ISA/EISA boards as Used
so the system BIOS will not try to assign these
IRQs to other PCI boards.
– In some systems the BIOS reserves a set of avail-
able IRQs for PCI boards, and you have to assign
these IRQs manually.
Common Problems and Solutions
■Changed Values Not Loaded—If you changed any
values on the host adapter in a Setup program or on a
SCSI device, select the Saved option to ensure that
the new values are loaded.
■Format/Verify Disk Device Utility Startup Fails—If
you tried to use the Format/Verify utility on a disk
device and got an Unexpected SCSI Command Fail-
ure pop-up box with error information, the utility
probably encountered a problem with the disk device
or the media and therefore cannot run.
You can probably determine from the Sense Key
information (e.g., 06h - Unit attention) both the cause
of the problem and its solution. Listed below are
some of the more common Sense Key values and
their meanings:
02h - Not ready—The media is not ready to for-
mat. Be sure that media is inserted in the drive
and that the media is spun up.
03h - Medium error—The disk media may be
defective. If it is a removable-media drive, try
using a different disk media. If it is a fixed disk
drive, the diskmay be physicallydamaged. Verify
and format the media with SCSISelect.
04h - Hardware error—The disk drive may be
defective. Consult the hardware documentation
and contact the manufacturer.
05h - Illegal request—The Adaptec formatting
utility does not support a low-level format of this
device; however, the device may already be low-
level formatted by the manufacturer. (This error
rarely occurs.)
06h - Unit attention—The removable media may
be write-protected. Disable write protection and
run the utility again.
