Installation Overview
=====================
This readme provides the information needed to install and use the Adaptec
7800 Family Manager (driver) for Windows NT 3.5.
If you are performing a first time Windows NT installation, see 'Installing
Windows NT and the Driver' below to begin driver installation. If Windows
NT is already installed in your system, see 'Updating Windows NT with the
Driver' below.
Installing Windows NT and the Driver
====================================
This section describes how to install the aic78xx.sys driver at the same
time you install Windows NT 3.5. If Windows NT 3.5 is already installed
and you wish to install or update the aic78xx.sys driver, see 'Updating
Windows NT with the Driver' below.
Installing Windows NT 3.5 and the Driver
=========================================
An older version of the aic78xx.sys driver is embedded (included) in the
Windows NT 3.5 installation disks (or CD). We recommend first installing
the embedded driver by following the instructions in your Windows NT 3.5
documentation for a normal Windows NT installation. Once the Windows NT
installation is complete, you can update the aic78xx.sys driver by following
the instructions in Updating Windows NT with the Driver below.
Note: During a normal Windows NT installation, the 7800 Family host adapter
is detected in your system and the embedded aic78xx.sys driver is
automatically installed.
If you are booting from a 7800 Family host adapter and you are unable to
install the embedded aic78xx.sys driver by performing a Windows NT
installation, then follow the instructions here to complete a fresh Windows
NT installation and install the aic78xx.sys driver from the 7800
Family Manager Set diskette for Windows NT.
Note: If your boot host adapter is the Adaptec AHA-2944W, you must complete
the instructions in this section to install the aic78xx.sys driver.
You may install Windows NT from a floppy drive or from a CD-ROM drive;
whichever you choose, make sure the hardware installation is completed
prior to following these steps.
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 Put 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 driver available from the 7800 Family Manager Set diskette
for Windows NT.
5 Press S to skip mass storage device detection. This allows you to
manually select the driver 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 diskette for Windows NT
into drive A and press Enter.
9 The screen displays the adapter drivers supported on the diskette.
The Adaptec AHA-2940/AIC-78xx (PCI) NT 3.5 driver is highlighted by
default; 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 onscreen and in the Windows NT
installation documentation.
Updating Windows NT with the Driver
===================================
This section describes how to update/install the aic78xx.sys driver if
Windows NT 3.5 is already installed. If you are installing Windows NT 3.5
for the first time, see 'Installing Windows NT and the Driver' above.
Updating Windows NT 3.5
========================
Follow these instructions only if Windows NT 3.5 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 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-2940/AIC-78xx (PCI) NT 3.5 driver is highlighted by
default; click OK. The driver is added to the list of SCSI adapters.
7 Select Adaptec AHA-2940/AIC-78xx (PCI) NT 3.5 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-2940/AIC-78xx (PCI) NT 3.5
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.
Removing a Host Adapter
=======================
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 these 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.
Swapping a Host Adapter
=======================
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.
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.
Troubleshooting
===============
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 and follow the
instructions on the screen to continue booting with the last known
good configuration:
Press spacebar NOW to invoke the Last Known Good menu
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.
If you cannot determine the source of the error, contact Adaptec Technical
Support for assistance at the telephone numbers listed below.
