          Version 8.0.1a of the adpu320 driver incorporates the following
          changes that were introduced in earlier versions of the driver:

          1. During an init state change, the adpu320 driver would cause
             a panic.

          2. A passthru REQUEST SENSE command would fail if the allocation
             length was greater than 18 bytes.
             fz529174

          3. Netvault fails with an Underrun/Overrun error.
             fz529174

          Version 8.0.1a of the adpu320 driver also introduces the 
          following changes:

          4. Eliminate a NULL pointer dereference error that caused
             kernel panics under certain conditions, such as when
             using the adpu320 HBA with an optical jukebox.
             fz534840

          5. Fix a lock hierarchy violation.

I. Installation

While installing UnixWare 7 or OpenServer 6 be sure to insert the
adpu320 Driver Supplement diskette before any HBA drivers supplied
with your media kit.

Use the following steps on a OpenServer 6/UnixWare 7 system to create
an HBA floppy from the HBA floppy image file.

    1. Become root and create a new directory by typing:

            $ su                         
            Password: <type your root password>                          
            # mkdir /tmp/hba                          
            # cd /tmp/hba                    

    2. Download the hba.adpu320.8.0.1a.image file to the newly          
       created /tmp/hba directory on your machine.                    

    3. Insert a formatted diskette in your diskette drive.

    4. Make an adpu320 HBA diskette from the image file using
       this command:

            # dd if=hba.adpu320.8.0.1a.image of=/dev/dsk/f0t obs=36b

    5. Use this adpu320 diskette during system installation. 

Use the following steps on a OpenServer 6/UnixWare 7 system to create
an HBA CD from the HBA ISO image file.

        1. Become root and create a new directory by typing:

                $ su
                Password: <type your root password>
                # mkdir /tmp/hba
                # cd /tmp/hba

        2. Download the hba.adpu320.8.0.1a.iso file to the newly
           created /tmp/hba directory on your machine.

        3. Make an adpu320 HBA CD from the iso file using this command:

# cdrecord -v -dev=c,b,t -dao -driveropts=burnfree -speed=99 
hba.adpu320.8.0.1a.iso

                where c,b,t is taken from the output of cdrecord --scanbus

        4. Use this adpu320 HBA CD during system installation.

II. Upgrading drivers on existing UnixWare 7 and OpenServer 6 systems

The adpu320 HBA diskette can also be used to install/upgrade the
adpu320 driver on your system using the following command:                    

      1. Insert the diskette containing the new driver and issue          
          the following command:                                    

             # pkgadd -d diskette1 all                                      

          or                                    

             # pkgadd -d diskette1 adpu320  

The adpu320 HBA CD can also be used to upgrade the megasas driver
on your system using the following command:

         1. Insert the HBA driver CD and type the command:

                # pkgadd -d cdrom1 all

                  or

                # pkgadd -d cdrom1 adpu320
