       3.0 Installation and Setup Instructions
       ---------------------------------------

       The AICU320.ADD Ultra320 SCSI driver only supports OS/2 Warp Server for
       e-business.

             3.1 Installing a New Driver or Updating an Existing Driver
                 3.1.1 Using "OS/2 Device Driver Install" Program 
                       NOTE: When installing a new host adapter, make sure it
                             is inserted in the system before installing the
                             driver.

                       1. Insert the Adaptecs OS/2 Ultra320 Device Driver
                          Installation Floppy in the appropriate floppy drive.

                       2. Select the "System Setup" Icon in the tools bar at
                          the bottom of the OS/2 desktop, select
                          "Install/Remove" and then select "Device Driver
                          Install".
                       
                       3. Alternatively, you can also accomplish the same by
                          opening on the OS/2 desktop, the "OS/2 System" folder,
                          the "System Setup" folder, the "Install/Remove" folder
                          and then double-click on the Device Driver Install
                          icon. 
                       
                       4. In the OS/2 Warp 4 Device Driver Installation dialog
                          box, if the Installation Floppy is not located in A:,
                          change the default Source directory to point to the
                          appropriate drive. The Device Driver Install program
                          makes use of the destination directory information
                          contained in the Device Driver profile file
                          (AICU320.DDP) on the floppy and installs the
                          AICU320.ADD driver into the \OS2\BOOT directory.
                          You can, however, also change that by specifying a new
                          Destination directory.

                       5. Select "Install..." to start the installation process.

                       6. *** IMPORTANT *** 
                          After the installation has been completed, be sure to
                          check the C:\ directory and delete any previous 
                          versions of the AICU320.ADD drivers before rebooting
                          the system. If you do not remove those drivers, OS/2
                          will load them instead of the new drivers that you
                          have just installed. You can easily check for the
                          existence of multiple copies of the driver by typing
                          at the C:\ prompt, dir aicu320.add /s.
			
                       7. Select EXIT and reboot the computer. 
				
                 3.1.2 Installing Manually
                       You may also install the driver manually by using the
                       following steps.
				
                       1. Copy AICU320.ADD to C:\OS2\BOOT. 
				
                       2. Add the following line to your CONFIG.SYS file:
                          BASEDEV=AICU320.ADD /V. 

             3.2 First-Time Installation from CD-ROM

                 NOTE: To install the driver, it is necessary to copy the 
                       driver from the Adaptecs OS/2 Ultra320 Device Driver
                       Installation Floppy on to the OS/2 Diskette 1. However,
                       before you can copy the driver, you must first remove
                       various files from the OS/2 Diskette 1, as explained
                       in step 2 below.
             
                 1. Type CDINST from CD-ROM drive and follow the instructions
                    to create the boot diskettes from the OS/2 Installation CD.
  	 		
                 2. Delete some of the existing files on the OS/2 Diskette 1
                    so that approximately 200 KB of disk space is available on
                    the diskette. Use the following information to help you
                    decide which files to delete: 
  	 		
                    - If the Ultra320 host adapter is the only Adaptec host
                      adapter installed in your system, delete all other Adaptec
                      drivers (aha152x.add, aha154x.add, aha164x.add,
                      aha174x.add, aic7770.add, aic7870.add, aic78u2.add and
                      fd16-700.add). 
                    - For each driver removed from the OS/2 Diskette 1, remove
                      its corresponding line in the config.sys file (also on
                      OS/2 Diskette 1). For example, if you deleted all Adaptec
                      drivers as explained in the above, remove the following
                      lines from the config.sys file:

                      rem basedev=aha152x.add
                      rem basedev=aha154x.add
                      rem basedev=aha164x.add
                      rem basedev=aha174x.add
                      rem basedev=aic7770.add
                      rem basedev=aic7870.add
                      rem basedev=aic78u2.add
                      rem basedev=fd16-700.add

                    - If you have deleted the suggested Adaptec drivers and you
                      still do not have approximately 200 KB of disk space
                      available on the diskette, delete the file: CDINST.EXE.

                 ***************************************************************

                 Note: The following files MUST NOT BE DELETED from Diskette 1:

                 CLOCK01.SYS, CLOCK02.SYS, IBM1S506.ADD, IBM1FLPY.ADD,
                 IBM2FLPY.ADD, IBM2ADSK.ADD, IBM2SCSI.ADD, IBMINT13.I13,
                 IBMKBD.SYS, KBDBASE.SYS, OS2LOGO, OS2DASD.DMD, PNP.SYS,
                 RESERVE.SYS, RESOURCE.SYS, SCREEN01.SYS, SCREEN02.SYS,
                 XDFLOPPY.FLT, and all *.SNP files.

                 ***************************************************************

                 3. Copy the driver from the Adaptecs OS/2 Ultra320 Device
                    Driver Installation Floppy onto the OS/2 Diskette 1
                    (\AICU320\AICU320.ADD). 

                 4. In the config.sys file on OS/2 Diskette 1, add the line
                    set copyfromfloppy=1

                 5. This line should be added so that the install process copies
                    the AICU320.ADD driver from the OS/2 Diskette 1, rather than
                    the driver included on the OS/2 CD-ROM. 

                 6. Add the following line to the top line of config.sys on OS/2
                    Diskette 1.
                    BASEDEV=AICU320.ADD /V

                 7. Run the OS/2 installation program; follow the instructions
                    in your OS/2 documentation, until you reach the System
                    Configuration window. 

                 8. In the System Configuration window, click the SCSI Adapter
                    Support icon. 

                 9. Deselect any highlighted adapters (including the Adaptec
                    294x, 394x, AIC7870 PCI SCSI), and click OK.

                    NOTE: If these adapters are not deselected, the driver
                          included on the CD-ROM will be copied over the driver
                          being installed.

                 10. Follow the instructions in your OS/2 documentation to
                     complete the installation.  


 

 

       4.0 Command Line Options
       ------------------------

       OS/2 adapter device drivers (.ADD files) are normally installed 
       automatically and require no further information from the user. However,
       in certain situations the user may wish to modify the behavior of the
       driver to meet their specific needs.

       IMPORTANT: Please proceed cautiously with the following information.

       The standard format for command line switches is:

       BASEDEV=AICU320.ADD [GlobalParam][AdapterID][UnitParam]{[ScsiTargetID]}

       GlobalParam   Global Parameters. These options apply to all adapters
                     controlled by the driver. 

          ET     Allow embedded targets. This parameter indicates that the ADD
                 should assume that all targets have more than one logical unit
                 (LUN) defined. 

          /!ET   Do not allow embedded targets (DEFAULT). This parameter
                 indicates that the ADD should assume that all targets have only
                 one logical unit (LUN) defined. 

          /V     Load driver verbosely. This parameter will display the driver
                 name as well as the version number and Adaptec copyright
                 information.  Information on all targets found in the system
                 will also be displayed. 

       AdapterID     The adapter ID # is assigned during the device driver
                     initialization and is based on the order that the adapters
                     are discovered in the system. Each channel on a host adapter
                     is considered as an independent adapter, hence, a 2 channels
                     host adapter is assigned with 2 consecutive adapter IDs.

          /A:n   where, n is the ID number (zero relative) of the host adapter
                 installed in the system.

       UnitParam     Unit Parameters.

          General:
          /I     Ignore the specified adapter. This allows another driver to 
                 share the adapters that the ADD would normally use. 

          /DM:   Enable DASD manager support (DEFAULT). This parameter allows
                 OS2DASD.DMD to control the specified target(s) if they are
                 identified as DASD (hard disk) devices. 

          /!DM:  Disable DASD manager support. This parameter prevents
                 OS2DASD.DMD from controlling the specified target(s). 

          /SM:   Enable SCSI manager support (DEFAULT). This parameter allows
                 OS2SCSI.DMD to control the specified target(s) if they are
                 identified as NON-DASD SCSI devices. All SCSI hard drives
                 will be controlled by OS2DASD.DMD. 

          /!SM:  Disable SCSI manager support. This parameter prevents
                 OS2SCSI.DMD from controlling the specified target(s). 

          /UR    Enables reporting of under runs (DEFAULT). 

          /!UR   Disables reporting of under runs. 

          Special:
          /TAG:n Specifies the maximum number (n) of tagged commands for all
                 target devices on the host adapter. A value of 1 disables
                 tagged queuing. The maximum number allowed is 16. The
                 default is 8. U320 devices are required to support tag
                 commands and the disconnect features. The driver will
                 negotiate with the U320 devices and adjust its settings
                 accordingly. The driver also maintains a maximum of 2
                 non-tagged commands per target internally and sends only
                 one non-tagged command at a time per target to the host
                 adapter.

       ScsiTargetID  SCSI Target IDs. The targets to which the Unit Parameter
                     will be applied. This parameter may be a single ID (d) or
                     list of IDs (d,d,d).
