                SE 4/66 AND ARCSERVE 4.0 NOVELL TAPE BACKUP SOFTWARE

    PROBLEM:       When running ARCSERVE 4.0 on an SE configured with a DPT EISA
                   controller the following error messages may appear; "0:0:0 DPT
                   Controller 0 Disk 0 Command timeout: Resetting Controller."
                   Tape Drive: Daemon Write Error H/W Error."

    CAUSE:         Command line parameters in the AUTOEXEC.NCF file

    AFFECTED
    SYSTEMS:       EISA systems using a FAST SCSI EISA HBA.

    SOLUTION:      In the AUTOEXEC.NCF file use the following command
                   line.

                   TAPEDRV SHOTS=1

                   This reduces the number of the upper limit of the I/O buffers
                   used by the software.
