                      PREMMIA LX SYSTEM HANGS DURING INSTALLATION OF OS/2 2.1

    PROBLEM:        When trying to install OS/2 2.1 on a Premmia LX with a Future
                    Domain PCI SCSI HBA the system hangs.

    CAUSE:          The existing FD16-700.ADD file is no longer valid.

    AFFECTED:           AST                                              REVISION
                    PART NUMBER            DESCRIPTION                     LEVEL

    SOLUTION:       Replace the existing FD16-700.ADD file with an updated
                    version.  This is done as follows:

                    CD-ROM INSTALLATION

                    1. Replace the FD16-700.ADD file, dated 4/29/93, on the IBM
                       OS/2 2.1 Setup Diskette #1 with the FD16-700.ADD file,
                       dated 1/10/94 or later.
                       FD16-700.ADD along with README.TXT are contained in
                       PCI_OS2.EXE which can be downloaded from the Future Domain
                       BBS (714-253-0432).

                    2. Run the OS/2 2.1 setup from the floppy diskettes.  This
                       will copy the  FD16-700.ADD file  on the OS/2 2.1 CD-ROM to
                       the hard drive using a character-based interface.

                    3  Prior to reloading OS/2 2.1, the FD16-700.ADD file which
                       was loaded on the disk must be replaced with the new
                       FD16-700.ADD file.

                    4. Reload OS/2 2.1 using the graphical interface.  Following
                       this configuration, the FD16-700.ADD file on the hard disk
                       must be replaced with the new FD16-700.ADD file (copied
                       from the BBS in step 1).  This step is required because the
                       old FD16-700.ADD file is recopied onto the hard disk from
                       the CD-ROM during the graphical configuration stage.

                    DISKETTE INSTALLATION

                    1. Replace the FD16-700.ADD file, dated 4/29/93, on the IBM
                       OS/2 2.1 Setup Diskette #1 with the FD16-700.ADD file,
                       dated 1/10/94 or later.  This file can be downloaded from
                       the Future Domain BBS (714-253-0432).

                    2. Run the normal OS/2 2.1 setup from the floppy diskettes.
