Changes From Prior Release
=-=-=-=-=-=-=-=-=-=-=-=-=-=

This release of the Adaptec 7800 Family Manager Set v3.03 adds the 
following support from the previous v3.02 release:

   o Support for PC99 Windows Hardware Quality Labs Certification
   
=-=-=-=-=-=-=-=-=-=-=-=-=-=
Installation Instructions
=-=-=-=-=-=-=-=-=-=-=-=-=-=

This section describes installing and using the Adaptec 7800 Family Manager
Set Driver (AIC78XX.SYS & AIC78U2.SYS) for Windows NT.

If you are performing a first time Windows NT installation, see the 
"Installing Windows NT v4.0 with the FMS Driver"  sections below.

If Windows NT is already installed on your system, see the "Updating the 
FMS Driver under Windows NT v4.0" sections below.


Installing Windows NT v4.0 with the FMS Driver
----------------------------------------------

The following instructions explain how to install the Adaptec 7800 Family
Manager Set, 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 diskette.
    
    6 For non-Ultra2 host adapters, Select the "Adaptec AHA290x/
      291x/294x/394x/4944/AIC78xx PCI SCSI Controller(NT 4.0)" 
      and press ENTER.  For Ultra2 host adapters, Select the "Adaptec 
      AHA-294xU2/295xU2/395xU2/AIC-789x 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 or AIC78U2.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.
     
Updating the FMS Driver under Windows NT v4.0
---------------------------------------------

Follow these instructions only if Windows NT v4.0 is already installed.

     1 Click the Start button on the Windows 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.
     
     4 In the "Install Driver" window, click the Have Disk button.
     
     5 Insert the Adaptec 7800 Family Manager Set driver diskette.
     
     6 At the "Copy manufacturer's files from" text box, 
       type a:\winnt\4_0\Ultra for non-Ultra2 adapters or 
       a:\winnt\4_0\Ultra2 for Ultra2 adapters and click OK. 
     
     7 At the Install Driver window, select the driver, then 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\Ultra or a:\winnt\4_0\Ultra2 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.

Removing a Host Adapter from Windows NT v4.0
--------------------------------------------

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 wish to remove.

       a.  For non-Ultra2 host adapters: 
       Select the driver you plan on removing and click the Remove 
       button.  The driver will appear as one of the following:
       "Adaptec AHA290x/291x/294x/394x/4944/AIC78xx PCI SCSI Controller
      (NT 4.0)"
       or                      
      "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"
       
       b.  For Ultra2 host adapters:
       Select the driver you plan on removing and click the Remove 
       button.  The driver will appear as the following:
       "Adaptec AHA-294xU2/295xU2/395xU2/AIC-789x PCI SCSI Controller(NT 4.0)"
       
     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 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 v4.0, up to Service Pack 3, 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 
      the "Installing Windows NT v4.0 with the FMS driver" section.

=-=-=-=-=-=-=-=-=
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 Start button (Windows NT 4.0).
  
      2 Enter REGEDT32 to run the Registry Editor.
     
      3 a. For non-Ultra2 host adapters:
         Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78xx.
        b. For Ultra2 host adapters:
         Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78u2.
          

      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.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
