150 MB SCSI Tape Cartridge
(250-4169)            Software Driver Installation     Faxback Doc. # 16822

ORDER OF INSTALLATION

Do not attempt to install the SCSI Driver until the tape drive is properly
installed and configured in your system.  Then, use these instructions to
install the SCSI Driver.  finally, install the SY-TOS software according to
the procedures in the 150 MB SCSI Tape Cartridge System Software User
Guide.

SCSI Software Driver Installation

Before using SY-TOS you must ensure that a CONFIG.SYS file is installed on
your system's boot disk and that CONFIG.SYS includes the path to the tape
device driver.  The device driver is a file named SCSIHA.SYS.  A SCSIHA.SYS
file is located on the SY-TOS Diskette.  (You received two diskettes, one
for a 3.5-inch drive and another for a 5.25-inch drive.)

To determine whether CONFIG.SYS already exists on your system, use the DOS
command DIR.  Refer to your DOS manual if you have questions about DOS
commands.  If a CONFIG.SYS file is not on your system boot disk, skip to
the "Creating CONFIG.SYS" procedure below.

If a CONFIG.SYS file exists on your system boot disk, you must then
determine whether the device driver has already been installed..  Use the
DOS command TYPE to display the contents of CONFIG.SYS.  If CONFIG.SYS has
a line that reads:  DEVICE = SCSIHA.SYS, the device driver has been
installed.  You may then ignore the rest of these instructions and proceed
to the installation of SY-TOS software.  If CONFIG.SYS does not include
that line, see "Modifying CONFIG.SYS."

CREATING CONFIG.SYS

Follow these steps to create a new CONFIG.SYS file.

1.  Insert the appropriate diskette in drive A and copy the SCSIHA.SYS file
    to the root directory of your boot disk using the DOS command COPY.

2.  Log on to your boot disk.  Then type:

    COPY CON: CONFIG.SYS <RETURN>
    DEVICE=SCSIHA.SYS <RETURN>
    F6 <RETURN>

3.  Reboot your system.  you may then install the SY-TOS software.

MODIFYING CONFIG.SYS

Follow these steps to modify an existing CONFIG.SYS file.

1.  Insert the appropriate diskette in drive A and copy the SCSIHA.SYS file
    to the root directory of your boot disk using the DOS command COPY.

2.  Using the DOS editor, EDLIN, or a word processor program, add the
    following to your CONFIG.SYS file:

    DEVICE=SCSIHA.SYS

3.  Reboot your system.  You may then install the SY-TOS software.
