Installation Instructions
=-=-=-=-=-=-=-=-=-=-=-=-=-=
This section describes installing and using the Adaptec 7800 Family Manager
Set Driver (aic78xx.sys) for Windows NT.
If you are performing a first time Windows NT installation, see Installing
Windows NT v4.0 or Installing Windows NT v3.5x and the Driver, below.
If Windows NT is already installed on your system, see Updating Windows NT
v4.0 or Updating Windows NT v3.5x, below.
Installing Windows NT v4.0 and the Driver
-----------------------------------------
The following instructions explain how to install the Adaptec 7800 Family
Manager Set v2.0, while installing Windows NT v4.0.
1 Start your system with the Windows NT Boot Diskette in
the floppy drive.
2 Insert diskette #2 when prompted. After a few moments you will see
a blue screen. To setup Windows NT now, press ENTER.
3 Press S to skip Windows NT Setup's auto detection of your SCSI
adapter.
4 Press S again to specify an additional device.
5 Press ENTER to select Others, and insert the Adaptec 7800 Family
Manager Set v2.0 diskette.
6 Select the "Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI
Controller (NT 4.0)" and press ENTER.
7 If you want to add other host adapters (that are not a part of the
7800 Family), do so at this time by pressing 'S' and repeating step 5
for each additional adapter and inserting the appropriate disk
provided by the hardware manufacturer. The Adaptec 7800 Family host
adapters use the same driver; it is not necessary to install the
aic78xx.sys driver again.
8 Press ENTER to continue with the Windows NT operating system setup.
Follow the instructions given on screen and in the Windows NT
installation documentation.
Installing Windows NT v3.5x and the Driver
------------------------------------------
The following instructions explain how to install the Adaptec 7800 Family
Manager Set v2.0, while you are installing Windows NT v3.5x.
1 If you choose to install Windows NT from a floppy drive, locate the
Windows NT Disk 1 for Floppy Installation.
If you are installing from a CD-ROM drive, locate the Windows NT Setup
Disk 1 for CD-ROM Installation.
2 Insert the diskette into drive A (not drive B) and turn on your
computer. When prompted, insert Windows NT Disk 2.
3 From the Welcome to Setup Screen, press ENTER to set up Windows NT.
4 When prompted, select Custom setup.
(NOTE: If you select Express setup, the embedded aic78xx.sys driver
included with Windows NT will be loaded and not the most recent
version of the driver available from the Adaptec 7800 Family Manager
Set v2.0 diskette for Windows NT.)
5 Press S to skip mass storage device detection. This allows you to
manually select the Adaptec 7800 Family Manager Set v2.0 for your host
adapter.
6 Since mass storage device detection was skipped in the previous step,
Windows NT Setup displays none in the list of recognized devices.
Press S to configure additional SCSI adapters.
7 From the list of additional SCSI adapters, expand the list, select
Other, and press ENTER. (Requires disk provided by a hardware
manufacturer).
8 Insert the Adaptec 7800 Family Manager Set v2.0 diskette into drive A
and press ENTER.
9 The screen displays the adapter drivers supported on the diskette.
Select the "Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI
Controller (NT 3.5x)" and press ENTER.
10 If you want to add other host adapters (that are not a part of the
7800 Family), do so at this time by repeating Step 7 for each
additional adapter and inserting the appropriate disk provided by the
hardware manufacturer. The Adaptec 7800 Family host adapters use the
same driver; it is not necessary to install the aic78xx.sys driver
again.
11 Press ENTER to continue with the Windows NT operating system setup.
Follow the instructions given on screen and in the Windows NT
installation documentation.
Updating Windows NT v4.0
------------------------
Follow these instructions only if Windows NT v4.0 is already installed.
1 Click the Start button on the Winows NT task bar, and the point
to Settings.
2 Open the Control Panel, double-click on SCSI Adapters.
3 Select the Drivers tab, and click the Add button.

and click OK.
7 At the Install Driver window, click OK.
8 In response to "Do you want to use the currently installed driver(s)
or install new one(s)", select the New button.
9 Again type a:\winnt\4_0 and click continue. The driver is now
installed.
10 You must restart your computer for the changes to take effect.
Click Yes to restart your computer. Click No to return to the
SCSI Adapters window.
Updating Windows NT v3.5x
-------------------------
Follow these instructions only if Windows NT v3.5x is already installed.
1 Select and start the Windows NT Setup program. (Its icon is usually
found in the Main program group.) There is a brief pause while Windows
NT Setup scans your hardware configuration.
2 Select the Options pull-down menu and then select Add/Remove SCSI
Adapters. The SCSI Adapter setup program displays a list of all host
adapters currently installed.
3 Click the Add button to add another host adapter type to the list. A
list of additional SCSI adapters appears.
4 Expand the list of additional SCSI adapters; select Other and press
ENTER. (Requires disk provided by the hardware manufacturer).
5 Insert the Adaptec 7800 Family Manager Set v2.0 diskette for Windows
NT into drive A; enter the following path to the installation files
and then click OK.
a:\winnt\3_5
6 The screen displays the adapter drivers supported on the diskette.
The "Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI
Controller (NT 3.5x)" driver is highlighted by default,
Click OK. The driver is added to the list of SCSI adapters.
7 Select "Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI
Controller (NT 3.5x)" from the list of SCSI adapters and click Install.
At this point, Windows NT Setup checks to see if the specified driver
(in this example, aic78xx.sys) has already been copied to the system
disk.
8 If the following message appears, click New to replace the existing
driver and skip to Step 10.
The driver(s) for this SCSI Adapter are already on the system. Do you
want to use the currently installed driver(s) or install new one(s).
If the following message appears, continue with Step 9:
Please enter the full path to the Windows NT SCSI Adapter files.
9 Change the path to the directory (i.e., a:\winnt\3_5) with the desired
device driver, then click Continue.
The device driver is copied to your system disk and the Windows NT
configuration is updated so that the new device driver loads when
Windows NT reboots.
10 When the installation is complete, Windows NT Setup again displays a
list of currently installed host adapter types. Verify that the new
host adapter appears on the list; the string should look similar to
"Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI Controller
(NT 3.5x)".
11 Add other types of host adapters if necessary (see Step 4 above), or
click Close to exit the SCSI adapters portion of Windows NT Setup,
and then close the program.
12 When you see this message, click OK to exit:
The changes you have made will not take effect until the computer is
restarted
If this message does not appear, no changes have been made to the
Windows NT system configuration.
13 Restart your computer and Windows NT. It is possible that some drive
letter assignments may change from the previous configuration.
The remainder of this section describes removing and swapping of host
adapters on Windows NT v3.5x and v4.0.
Removing a Host Adapter on Windows NT 3.5x
------------------------------------------
Removing a host adapter can be as simple as physically removing it from the
slot when your computer is shut down. Windows NT boots and functions
properly in this configuration, but a warning message is generated every
time you boot Windows NT.
(CAUTION: If you have removed a host adapter but still have other host
adapters of the same type installed in your computer, do not use Windows NT
Setup to remove the device driver.)
To eliminate the warning message, you must update the Windows NT software
configuration, as described in the following steps:
1 Select and start the Windows NT Setup program. There is a brief pause
while Windows NT Setup scans your hardware configuration.
2 Select the Options pull-down menu and then select Add/Remove SCSI
Adapters. The SCSI Adapter setup program displays a list of all host
adapters currently installed.
3 Select the host adapter you want to remove and click the Remove
button. When the Windows NT Setup program asks you for confirmation,
click OK.
Because SCSI device drivers are loaded during system bootup and
because they may be needed to load Windows NT itself, a screen may
appear warning you that Windows NT may not start if you remove the
SCSI adapter.
4 If you are sure you are removing the correct host adapter type, click
OK.
5 Return to Step 3 if you want to remove driver support for other types
of host adapters, or click Close to exit the SCSI adapters portion of
Windows NT Setup.
6 Close the Windows NT Setup program. When the following message
appears, click OK to exit.
The changes you have made will not take effect until the computer is
restarted.
If this message does not appear, no changes have been made to the
Windows NT system configuration.
7 Restart the computer.
(NOTE: Windows NT Setup does not delete the device driver from your
system disk; it only updates Windows NT software configuration
information so that the device driver is no longer loaded during
system bootup.)
Removing a Host Adapter on Windows NT 4.0
-----------------------------------------
Removing a host adapter can be as simple as physically removing it from the
slot when your computer is shut down. Windows NT boots and functions
properly in this configuration, but a warning message is generated every
time you boot Windows NT.
(CAUTION: If you have removed a host adapter but still have other host
adapters of the same type installed in your computer, do not use Windows NT
Setup to remove the device driver.)
To eliminate the warning message, you must update the Windows NT software
configuration, as described in the following steps:
1 Open the Control Panel, double-click on SCSI Adapters.
2 Select the Drivers tab.
3 Select the driver you plan on removing and click the Remove
button. The driver will appear as one of the following:
"Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI Controller
(NT 4.0)"
or
"Adaptec AHA-294X/AHA-394X or AIC-78XX PCI SCSI Controller"
4 If you are sure you are removing the correct host adapter type,
click Yes.
5 You must restart your computer for the changes to take effect.
Click Yes to restart your computer. Click No to return to the
SCSI Adapters window.
Swapping a Host Adapter for both v3.5x and v4.0
-----------------------------------------------
Swapping one type of host adapter for another is similar to the procedure
for adding a host adapter. The important distinction is that you make all
software configuration changes while Windows NT is running and before you
make the hardware changes.
(NOTE: If you do not install the driver that comes with the new host
adapter, it may result in Windows NT failing to boot.)
1 Install the driver for the new host adapter by following the steps in
Updating Windows NT with the Driver, above.
It is not essential to remove the device driver for the host adapter you
are replacing. Windows NT dynamically detects the absence or presence of
host adapter hardware, and no problems should arise if you leave the
existing device driver installed. You may remove the device driver later,
after you have successfully rebooted Windows NT. However, if you leave the
driver in, the system alerts you with an error message of the extra device
driver every time you boot. See Removing a Host Adapter above.
2 Once the new device driver is installed, shut down Windows NT and
replace the existing host adapter.
3 Restart your computer and Windows NT. It is possible that some drive
letter assignments may change from the previous configuration.

Known Issues
=-=-=-=-=-=-=
o For Windows NT v3.5x, the embedded (included) miniport driver on the
CD-ROM or diskettes, does not include support for Ultra host
adapters (i.e., host adapters with the letters AU, U, UW, AUW, and
AUWD at the end of the model number) and AHA-2944W. Refer to the
installation instructions in Installing Windows NT v3.5x and the
Driver.
o For Windows NT v4.0, the embedded (included) miniport driver on the
CD-ROM, does not include support for AHA-3940AUWD, AHA-3944AUWD, or
AHA-4944W. Refer to the installation instructions in Installing
Windows NT v4.0 and the Driver.
o An issue exists in Windows NT 3.5x with the Windows NT Setup
Application. In the Add/Remove SCSI Adapters selection, under the
Options pull-down menu, you should see:
"Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI Controller
(NT 3.5x)"
and possibly one or more of the following
"Adaptec AHA-294x/AIC-78xx (PCI)"
"Adaptec AHA-2940/AIC-78xx (PCI) NT v3.5x"
as listed choices. This behavior is due to differences between
the embedded SCSI.INF file and the OEMSCSx.INF that was created when
installing/updating the aic78xx.sys. All of these choices, refer to
the same Adaptec 7800 Family Manager Set v2.0 driver in your system.
Removing any one of them, without the intention of either replacing
or upgrading, may result in your system failing to boot.

Additional Notes
=-=-=-=-=-=-=-=-=
o If disconnection is disabled under SCSISelect for a hard disk device,
the system may hang if the hard disk device supports tagged queuing.
It is recommended to always enable disconnection for hard disk
devices. By default, disconnection is enabled so no action is
required. If for some unique requirements disconnection has to be
absolutely disabled for hard disk devices, you can turn off tagged
queue requests by editing the Windows NT Registry. You can do so
by following these instructions:
1 Select Run from the File pull-down menu (Windows NT 3.5x), or Run
from the Start button (Windows NT 4.0).
2 Enter REGEDT32 to run the Registry Editor.
3 Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78xx.
4 Create a key named Parameters by selecting Add Key from the Edit
pull-down menu and entering "Parameters" (without quotations) in
the edit-box for Key Name. Leave the Class edit-box blank.
5 Open Parameters and create a key named Device by selecting Add Key
from the Edit pull-down menu. Enter "Device" (without quotations)
in the Key Name edit-box. Leave the Class edit-box blank.
6 Open Device. Select the Add Value option from the Edit pull-down
menu. In the Value Name edit-box, enter "DisableTaggedQueuing"
(without quotations). Select the Data Type REG_SZ from the
droplist combo box.
7 Shutdown and restart Windows NT.
8 Set Enable Disconnection to No for your particular device(s) in
SCSISelect during bootup. (See your Host Adapter manual on how to
use SCSISelect).
o If the logical driver letters assigned by the BIOS change when the NT
operating system is running, it's not an error. To preserve drive
letter assignments between BIOS and NT, run the NT disk administrator
and choose permanent drive letters assignments as an option. NT will
then preserve logical driver letter assignments across boots and
adapters.
o The boot manager for Windows NT contains recovery logic to allow you
to return to the last known good configuration. If you have changed
your host adapter configuration and Windows NT no longer boots, follow
these steps to recover:
1 Undo any hardware changes you have made to the computer since it was
last operational.
2 Reboot the computer. Watch the display carefully during bootup. If
the following message appears, press the Spacebar.
Press spacebar NOW to invoke the Last Known Good menu
Follow the instructions on the screen to continue booting with the
last known good configuration. For Windows NT 4.0 only, hit the
letter "L", to switch to the last known good configuration.
3 Once your computer is operational again, check all of the hardware
and software configuration changes you want to make. Look
specifically for conflicts with parts of the existing system
configuration that are not being changed.
