Installing or Updating the Driver With Win- dows NT

Installing or Updating the Driver With Win- dows NT 3.51

Follow these instructions only if Windows NT 3.51 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.

If you are installing the driver for the first time, skip to step 5.

If you are updating the driver, continue to step 3.

3.Before you can update the driver, you must first remove the existing driver. Select the host adapter you want to remove (for example, the Adaptec AIC-78xxSCSI controller), and click Remove. When the Windows NT Setup program asks you for confirmation, click OK.

Because SCSI device drivers are loaded during sys- tem start-up and because they may be needed to load Windows NT itself, the following warning message may appear:

Removing SCSI Adapters may prevent Windows NT from starting correctly.

4.When you are sure you are removing the correct host adapter driver, click OK.

5.Click Add to add another host adapter type to the list. A list of additional SCSI adapters appears.

6.Expand the list of additional SCSI adapters; select Other and press <Enter>.

7.Insert the Windows NT 3.51 driver diskette you created into drive A, enter the following path to the installation files, and then click OK.

a:\scsi

8.The screen displays the adapter drivers sup- ported on the diskette. The Adaptec AHA-2940UW/AIC-78xx(PCI) NT 3.51 driver is highlighted by default; click OK. The driver is added to the list of SCSI adapters.

9.Select Adaptec AHA-2940UW/AIC-78xx (PCI) NT 3.51 from the list of SCSI adapters, and click Install.

At this point, Windows NT Setup checks to see if the specified driver (aic78xx.sys) has already been cop- ied to the hard-disk drive.

10.If the following message appears, click New to replace the existing driver and go to step 12.

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 to step 11:

Please <Enter> the full path to the Windows NT SCSI Adapter files.

11.Change the path to the directory with the desired device driver (for example, a:\scsi); then click

Continue.

The device driver is copied to your hard-disk drive and the Windows NT configuration is updated so that the new device driver loads when Windows NT reboots.

12.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-2940UW/AIC-78xx (PCI) NT v3.5x

13.If you want to add other host adapters (that are not part of the Adaptec 78xx series), do so at this time by repeating steps 6 through 8 for each addi- tional adapter, inserting the appropriate diskette provided by the hardware manufacturer. Because all Adaptec 78xx series host adapters use the same driver, you configure all Adaptec host adapters at the same time.

14.Click Close to exit the SCSI adapters portion of Windows NT Setup, and then close the program.
