      drivers).  Make sure you remove all entries referring to any
      device drivers you delete from the CONFIG.SYS file.

  3.  Edit the CONFIG.SYS file on the Copy of OS/2 Diskette 1 to
      add the following lines:

        BASEDEV=IPSRAID.ADD
        SET COPYFROMFLOPPY=1

  4.  Install OS/2, but when prompted to insert diskette 1, use
      the updated Copy of OS/2 Diskette 1.

      o   The program copies the ServeRAID IPSRADM.HLP Help file to
          the \OS2\HELP directory.

  10.  Edit the CONFIG.SYS file and verify that there is only one
      copy of the line BASEDEV=IPSRAID.ADD.

      NOTES:

      a.  If you have more than one ServeRAID or SCSI adapter in
          your system, make sure that the BASEDEV statement for the
          adapter controlling the startup (boot) device appears before
          the BASEDEV statements for other ServeRAID or SCSI adapters
          in the CONFIG.SYS file.

      b.  After you install any service packs, check the path for
          the IPSRAID.ADD device driver and verify that the correct
          device driver is installed.

  11. Restart the server.

      NOTES:

      a.  If you have more than one ServeRAID or SCSI adapter in
          your system, make sure that the BASEDEV statement for the
          adapter controlling the startup (boot) device appears before
          the BASEDEV statements for other ServeRAID or SCSI adapters
          in the CONFIG.SYS file.

      b.  After you install any service packs, check the path for
          the IPSRAID.ADD device driver and verify that the correct
          device driver is installed.

  7.  Restart the server.


  4.30  Starting the Administration and Monitoring Program
  --------------------------------------------------------

  To start the ServeRAID Administration and Monitoring Program for
  OS/2:

  1.  Go to the OS/2 subdirectory on the hard disk drive; then, type:

      "ipsradm" /lf=d:\path\logfile

      NOTES:

      a.  Make sure that the path you type exists.  The program
          will not create a path.

      b.  Logfile is where the program will log messages.

      c.  If you omit the /lf parameter, the program will create the
          IPSRADM.LOG default file in the OS2 subdirectory to log the
          program messages.

  2.  Press ENTER.

  3.  Use the following steps if you want to define IPSRADM to OS/2:

      a.  Open the Templates Folder on the OS/2 Desktop.

      b.  Drag a program template onto the Desktop.  A Program
          Settings window will appear.

      c.  At the Program page in the PATH AND FILE NAME field, type:

            c:\os2\ipsradm.exe

      d.  In the PARAMETERS field, type:

            /lf=d:\path\logfile

      e.  At the General Tab in the TITLE field, type:

            ServeRAID
