Procedure for Upgrading Firmware on WangDAT 3100, 3100DX, 3200 and 
3400DX Tape Drives


This utility must be run from a DOS command prompt.  If a DOS platform
is not available, a bootable floppy disk may be used.  

WARNING:  KNOW YOUR VERSION OF FIRMWARE BEFORE ATTEMPTING ANY FIRMWARE
DOWNLOAD.  ALL DRIVES CANNOT BE UPGRADED TO THE CURRENTLY POSTED 
VERSION.  ATTEMPTING TO DOWNLOAD AN INCORRECT FIRMWARE VERSION MAY 
RENDER THE DRIVE INOPERABLE.  IN THIS EVENT, THE DRIVE WOULD HAVE TO
BE SENT TO TECMAR TECHNICAL SUPPORT TO HAVE THE DRIVE RETURNED TO THE
ORIGINAL FIRMWARE VERSION.  THERE IS A $50.00 FEE FOR THIS SERVICE.


Below is a chart of compatible firmware versions.  Please review the

3900	Contact Technical Support - no downloadable firmware available.

*	Tecmar Dat 2000, 4000 and 8000 models with Read/Write/Select 
        indicator lights should not be upgraded from 2.2 to 2.5. Doing 
        so will disable the lights.
**	Drives with firmware 2.0A cannot be upgraded via the download 
        file.  They must be returned to Tecmar.


Before you begin, verify the following:

1.  The drive is attached to a SCSI host adapter.

2.  A config.sys file is loading which contains a device line pointing
    to the correct ASPI driver for the installed host adapter.

    Example:  for an Adaptec 154x controller, add the following line:

		device=c:\apsi4dos.sys /d
	
    The device statement should denote the path to the aspi driver.

3.  There is not a tape cartridge in the drive.

NOTE:	A POWER LOSS TO THE DRIVE DURING THE UPGRADE PROCEDURE CAN 
        CAUSE DAMAGE TO THE DRIVE.  



To Process the Firmware Upgrade:

1.  Type the following command:

	download xxxxx.dfi n

	x's = firmware file name
	n = Tape drive SCSI id number

Example -   to upgrade firmware on a 3400DX set to SCSI id 4 to 
            version 5.0F, enter the following at the DOS command 
            prompt:

	download 34FAS50F.dfi 4

2.  The LEDs on the front of drive will display a sequence of flashes.  

3.  When the upgrade procedure has completed, the LEDs will stop 
    flashing and the drive will return to a ready state.  At this 
    point, the system should be rebooted to allow the SCSI controller 
    to recognize the new firmware.
