       select "Save Parameters and Continue".
    7. When "Install addition driver" appears, select "YES" if installing 
       more than one host adapter or installing a dual-channel host adapter,
       and repeat step 5 & 6 until one driver is chosen for each host 
       adapter; otherwise, select "NO".
    8. Select "Continue with Installation" to continue the installation.
    9. You will be prompted to confirm slot option, press "Enter" to 
       select the slot number. Repeat until all slot options are loaded.
   10. Select "Continue with Installation" to complete the installation.

    (NOTE: To load the driver automatically at server bootup, make sure
    the STARTUP.NCF file includes the load command line for your host
    adapter.  See "Loading the Driver at Server Bootup", below.)


Installing an Ultra2 Host Adapter and NetWare v5.x for the First Time
---------------------------------------------------------------------

Follow these instructions only if you are installing NetWare v5.0 for the first time:

1. Begin installation of NetWare v5.0 on your server as instructed in your NetWare documentation.
2. When a screen appears that asks you to add device drivers, choose "Modify" and press ENTER.
3. Choose "Storage Adapters", and press ENTER.
4. Press INS to add storage devices.
5. Press INS to add an unlisted driver.
6. Insert the Adaptec 7800 Family Manager Set for NetWare diskette into your disk drive.
7. Press F3 and specify the path to the AIC78U2.HAM driver for NetWare (e.g., a:\netware on the diskette).
8. Select AIC78U2.HAM and press ENTER.
9. You will be prompted to confirm slot option, press "Enter" to select the slot number. Repeat until all slot options are loaded.
10. When "Install addition driver" appears, select "YES" if installing more than one host adapter or installing a dual-channel host adapter, and repeat step 5&6 until one driver is chosen for each host adapter; otherwise, select "NO"
11. Select "continue with Installation" to continue the installation.

NOTE: To load the driver automatically at server bootup, make sure the STARTUP.NCF file includes the load command line for your host adapter. See "Loading the Driver at Server Bootup", below.


Installing the Driver in an Existing NetWare 4/5 Installation 
---------------------------------------------------------------
      
To update or install the AHA2940.HAM or AIC78U2.HAM driver when NetWare v4.0 
is already installed, follow the instructions in this section. The recommended way for updating the driver is through 'install' program under NetWare 4.0 or v4.x and 'nwconfig' under NetWare 5.0. Procedures that are specific to a
NetWare version are noted when necessary.

1. Make a backup copy of the old driver (if it exists) before installing the new driver.
2. At the console prompt type 'load install" in case of v4.0 or v4.x and 'nwconfig' in the case of v5.0
3. Select "driver Options (load/unload disk an network drivers)".
4. In the driver options select "configure disk and storage device drivers".
5. Select "Select and additional driver".
6. Copy the AHA2940.HAM or AIC78U2.HAM driver from the 7800 Family ManagerSet diskette for NetWare into the server's startup directory (e.g. c:\nwserver, c:\server.40, etc.) on your hard disk.  This overwrites any existing version of the driver in the directory.
7. If necessary, modify the load command line in the STARTUP.NCF so that
       the proper path to the driver and all appropriate command line 
       options are specified.  See the "Loading the Driver at Server Bootup 
       and Command Line Options sections, below.)
      
       The correct syntax to load the 7800 Family Manager driver is:
      
       	load [pathname]aha2940 [options]
       	or
       	load [pathname]aic78u2 [options]
      
       Command line options are not case sensitive.  Placing commas between 
       command line options is optional.  See "Command Line Options", below,
       for possible values.
      
     
Loading the Driver at Server Bootup
-----------------------------------

To automatically load the AIC7870.DSK or AIC78U2.HAM at server bootup, the 
STARTUP.NCF file (usually located in your server's startup directory) must 
contain a load command line that specifies the location of the driver and any 
appropriate command line options (see Command Line Options, below).
For additional information on the STARTUP.NCF file, refer to your NetWare
documentation.

(NOTE: To load the driver from your hard disk, the AIC78U2.HAM or AHA2940.HAM driver and must be copied from the Adaptec 7800 Family Manager Set
diskette for NetWare to a directory on your hard disk [usually the
server's startup directory (e.g., c:\nwserver)]).

The correct syntax to load the driver is

    load [pathname]aha2940 [options]
    or
    load [pathname]aic78u2 [options]

For example, the command line to load the driver from the c:\nwserver 
directory, with the "verbose=" option on is

    load c:\nwserver\aha2940 verbose=y
    or
    load c:\nwserver\aic78u2 verbose=y

Command line options are not case sensitive.  Placing commas between command 
line options is optional.  See Command Line Options, below,  for possible
values.

To modify the STARTUP.NCF file, follow these steps:

(NOTE: You can also use your DOS text editor to modify the STARTUP.NCF 
file.)

    1 Type load install at the NetWare prompt and press ENTER.
    
    2 Select the appropriate menu choice that allows you to edit the 
      STARTUP.NCF file.
    
    3 Make the necessary changes.  When you are done, press ESC.



=-=-=-=-=-=-=
Known Issues
=-=-=-=-=-=-=

o  There is a known problem which occurs during the installation of Netware
   4.0X, that involves the DDI file used during the initialization of the
   host adapter device driver. The DDI file does not contain all the
   possible slot number options available on all PCI systems, as there are
   too many combinations. As a result, during the installation procedure,
   NetWare will report that it is unable to load the driver in the given
   amount of time.  This is because the DDI file does not contain any
   slot options, which causes NetWare not to load the driver. Note, however,
   that this is not an error. The user simply needs to go to the console
   screen and manually enter in the correct slot number and installation
   will continue.

o  A second known problem exists that will hang the server after loading the
   host adapter device driver. This problem involves targets that do not
   support scanning of multiple luns, with the command line option 
   lun_enable.  The user simply needs to set the command line option
   multlun_targets to only scan targets that support multiple luns.  This
   problem is known to occur with Quantum Empire 540S drives.

o  Novell recommends not using IRQ 15 for host adapters.  If your system
   bios allows the assignment of IRQs, change your adapters IRQ to a value
   other than 15.

o  On NetWare 4.11, without media in the CD-ROM drive, and using built in 
   driver support for CD-ROMs, the message "No CD-ROM Devices Registered 
   with NetWare." is reported, if "cd device list" is issued.

o  There is a known problem with some hard drives that are less than or
   equal to 1 GB. If these drives were previously formatted using the
   Adaptec 7800 Family Manager Set v2.1x driver for Netware, and are now
   being upgraded to the 7800 Family Manager Set driver, the user
   may have problems in finding the device during initialization. If 
   this occurs, use the following command line option in your STARTUP.NCF
   file:

      ext_tran=n

o  On some system configurations and during a first time installation or
   when upgrading to the 7800 Family Manager Set v3.03 driver, the user
   may see a window with the following warning message:

      "One or more partitions on drive 0 are inconsistent with the driver
      geometries (xxx heads, xx sectors, and xxx cylinders) that NetWare
      is using. You may continue and edit the partition anyway, although
      this inconsistency could create problems later on."

   This message is shown when the "Installation Options" window appears,
   and the user highlights and selects "Disk Options", followed by "Modify
   Disk Partitions and Hot Fix". The user should simply continue to the
   "Disk Partitions Options" window to edit the partition, and installation
   will complete successfully.

o  The AIC78U2.HAM driver will not load if older versions of the NWPA.NLM
   file have been used. To fix this problem, use the updated version of
   the NWPA.NLM file that is included in this diskette.

o  The AIC78U2.HAM driver requires a minimum of 16 MB of memory.

o  When starting a NetWare server with two Ultra2 host adapters, the 
   error message "Unbound Device Object" might appear.  Manually unloading
   and reloading the driver will fix the problem, as well as removing
   the "slot=xx" option in the STARTUP.NCF file (and then selecting the 
   default slot number(s)).  This is being addressed by Novell.

o  When loading server.exe with the ""load aic78u2.ham slot=# lun_enable""
   switch, the server locks up while scanning the LUNs.  This is
   being addressed by Novell.

o  On some SMP systems, if the IRQ setting is set to "Auto" in the 
   system's BIOS then NW 4.11 installation will hang at loading a NIC 
   driver.  This problem was tested with a Tyan P5 SMP, and it did 
   show up.  The problem did not show up on the DEC SMP system.  This is 
   being addressed by Novell.

o  Certain systems will not run Sbackup under NetWare v3.12.  NetWare 
   v4.11 runs it with no problems.  This is an issue which is 
   currently being addressed by Novell.

o  Some systems experienced problems loading NetWare when loading
   the AIC7870.DSK and ASPICD.DSK drivers after the AIC78U2.HAM 
   driver.  The workaround is to load the DSK drivers before the 
   HAM driver. 


=-=-=-=-=-=-=-=-=
Additional Notes
=-=-=-=-=-=-=-=-=

o  The NetWare driver has been submitted for Novell Certification.

o  All of Adaptec's NetWare drivers have full support for standard
   SCSI disk drives, "NetWare Ready" drives, and removable media disk
   drives (including optical drives

o  For NetWare patches and other latest information, reference the
   Novell website at http://developer.novell.com/cgi-bin/devnet

o  The AIC78U2.HAM driver also supports applications that use the ASPI
   interface to access devices on a NetWare Server, through NWASPI.CDM.
   This CDM is not included with the current release, but can be downloaded
   from http://developer.novell.com/engsup/sample/areas/smsi.htm.

o  If your file server does a lot of IO operations and you want to try
   optimizing its performance, you can adjust the "max_tags=?" command
   line switch.  This switch controls the maximum number of tagged
   commands outstanding at a given device.  Refer to your disk-drive's
   documentation to determine if tagged-queuing is supported, and the
   maximum number of outstanding commands supported. Its default value
   is 16.

   The following are examples of how to change this feature:

   For all 7800 Manager Set host adapters:
      :load aha2940 max_tags=2
   For UltraSCSI or earlier only host adapters:
      :load aha2940 tag_disable=ffff

   The first example shows how to use the max_tags command line option.
   The max_tags parameter can be set between 1 and 128.  Larger values
   give the drives more opportunity for optimization, but take up more
   memory in the server.

   For several reasons, you may want to use a lower value of max_tags.
   For some drives, maximum performance is achieved with
   a max_tags less than the maximum supported by the drive.
   Also, some drives may not support the driver's maximum count of 128,
   or may suffer starvation problems with large counts, leading to
   drive deactivation.

   The second example applies only to the AIC7870.DSK driver. It turns
   off tagged-queuing for all devices. This may be necessary for 
   starvation-prone drives.

o  The Adaptec 7800 Family Manager Set NetWare driver no longer supports the   slot=0 command line option. For the AHA2940.HAM (UltraSCSI) or AIC78U2.HAM (Ultra2SCSI) driver, if no slot is mentioned on the command line, the driver is loaded for all host adapters present in the system. For the Ultra2SCSI AIC78U2.HAM driver, if no slot is mentioned on the command line, the driver prompts you for a valid slot number.

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.
