5. REGISTRY PARAMETERS
   5.1 Driver Specific Registry Parameters

       WARNING: Altering or adding these driver parameters
       incorrectly can render your system inoperable.
       Use them with caution.

        Follow the instructions below to enter the registry values
        that affect the configuration information for Adaptec SCSI
        Card drivers. All SCSI Cards supported by the installed
        driver are affected by the values you enter here.

        Each driver has its own "key" reference. In this example,
        the Ultra320 key is used (adpu320). To enter 
        driver-specific parameters, follow these steps: 

        1) Select Run from the Start button.
        2) Type "regedt32" and press Enter.
        3) Open the registry list to the following location: 

           HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
           adpu320\Parameters\Device\
   
           If the \Parameters\Device\ keys already exist, skip to
           step 6 below to begin entering parameters. If the keys
           do not yet exist, you will need to create them by 
           continuing with step 4.
        4) Click on the adpu320 key. Select the Add Key from the
           Edit menu; Type "Parameters" in the Key Name edit box.
           Leave the Class edit box blank.
        5) Click on the Parameters key. Select the Add Key from the
           Edit menu; Type "Device" in the Key Name edit box. Leave
           the Class edit box blank. To specify a certain host 
           adapter, append Device with the number of the host 
           adapter. For example, type "Device0" for the first host
           adapter, "Device1" for the second, etc. If you omit the
           host adapter number, the configuration information
           applies to all supported host adapters.
        6) Click on the Device key. Select Add Value from the Edit
           menu; type "DriverParameters" in the Value Name edit 
           box. Enter the Data Type and press Enter. A String 
           Editor text box appears. Enter valid parameters in the
           text box. When entering multiple parameters, each
           parameter must be separated by a space. To enter 
           additional values, repeat step 6. 
   
     Note: Changes made with the Registry Editor do not take effect
           until you shut down and then restart your system.

                    elements -1)
         Data Type: REG_SZ
   Possible Values: 2-255
     Default Value: 65

   5.2. Windows SCSI Driver Parameters

       WARNING: Altering or adding these driver parameters
       incorrectly can render your system inoperable.
       Use them with caution.

        Follow the instructions below to enter the registry values
        that affect how the Windows SCSI manager interprets the
        generic configuration information of SCSI device drivers. 
        All SCSI Cards supported by the installed driver are 
        affected by the values you enter here.

        Follow the instructions below to enter the registry values
        that affect the configuration information for Adaptec SCSI
        Card drivers. All SCSI Cards supported by the installed
        driver are affected by the values you enter here.

        Each driver has its own "key" reference. In this example,
        the Ultra320 key is used (adpu320). To enter Windows
        parameters, follow these steps: 

        1) Select Run from the start button.
        2) Type "regedt32" and press Enter.
        3) Open the registry list to the following location: 

           HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
           adpu320\Parameters\Device\
   
           If the \Parameters\Device\ keys already exist, skip to
           step 6 below to begin entering parameters. If the keys
           do not yet exist, you will need to create them by 
           continuing with step 4.
        4) Click on the adpu320 key. Select the Add Key from the
           Edit menu; Type "Parameters" in the Key Name edit box.
           Leave the Class edit box blank.
        5) Click on the Parameters key. Select the Add Key from the
           Edit menu; Type "Device" in the Key Name edit box. Leave
           the Class edit box blank. To specify a certain host 
           adapter, append Device with the number of the host 
           adapter. For example, type "Device0" for the first host
           adapter, "Device1" for the second, etc. If you omit the
           host adapter number, the configuration information
           applies to all supported host adapters.
        6) Click on the Device key. Select Add Value from the Edit
           menu. In the Value Name edit box, enter one of the valid
           parameter values. Make sure to enter the appropriate
           Data Type for the value. To enter additional values, 
           repeat step 6. 
   
     Note: Changes made with the Registry Editor do not take effect
           until you shut down and then restart your system.

     Default Value: N/A
   ----------------------------------------------------------------
            Option: DisableDisconnects

6. Known Issues and LIMITATIONS
   
    - Multi-initiator configurations are supported with
      Ultra160 and previous generation hard drives:

      Current generation Ultra320 hard drives do not 
      support this configuration.

    - An Event 9 in the Event Viewer may occur with a 
      DLT 7000 or 8000 tape device:

      If this occurs, install the registry fix (MAXIO64K.REG) 
	  located in the Windows Driver directory.

    - Ultra320 hard disk drive support

      Adaptec only supports Ultra320 hard drives that have
      the latest firmware available. Please check with
      your hard drive manufacturer to ensure you have the
      latest version.
