                            THE BKSETUP PROGRAM 
                           

          To properly install Back-It 4 onto your computer's hard drive,
          you must run the BKSETUP program.  To do so, make your floppy
          drive the current drive.  Then, put the Back-It 4 floppy diskette
          into your floppy drive and run BKSETUP.

          For example, if you are using drive A to install Back-It 4 onto
          your hard disk, do the following:

          1.	Type A: and press ENTER.  This makes drive A the
          	default drive.

          2.	Now, type BKSETUP and press ENTER.  This runs the
          	installation program.  From this point on, follow the
          	simple instructions displayed on your screen.

                     TESTING BACK-IT 4 ON YOUR COMPUTER 
                    

          Before you can run Back-It 4 on your computer, you must first
          test your computer's DMA controller chip.  When you use the
          BKSETUP program to install Back-It 4, it will automatically test
          the DMA chip.  If you do not use BKSETUP to install Back-It, you
          should run DMATEST yourself to insure that Back-It can reliably run
          at its highest speed on your computer.

          In some cases, using DMATEST will cause your computer to "freeze."
          This is a result of a DMA controller which cannot support the
          "FAST" speeds used in Back-It 4.  If your computer freezes during
          the test, you must set Back-It 4's DMA speed to "NORMAL".

          Back-It 4 now directly supports a number of tape drives.
          Please refer to the Back-It 4 users guide and the TAPE.TXT
          for further information. The users guide will describe how
          to configure and to run the tape section.  The TAPE.TXT
          will list the Tape drives that we currently support.

          Back-It 4 will backup files from any network that supports
          standard DOS commands.  Some networks, such as Novell's Netware
          2.xx, have special files and trustee rights and information that
          should be saved with the backup -- Back-It 4 will not save this
          special information, but will be able to backup all other files
          on most networks.

          Back-It 4 LAN, the network-specific Back-It, WILL backup the
          special files created by Netware.  Call Gazelle Systems for more
          information.

          3270 emulators should not be loaded while Back-It 4 is running
              a System hang will occur.

          Fax Software - When loaded in the background is not compatible
              with Back-It 4.

          Print Cache - If PCACHE.EXE is loaded in the background while
              running a Backup or restore the data backed up will be
              corrupted.  There will be no sign during the backup however
              upon restore the file names will be wrong and the system
              may hang.

          SideKick if loaded will either cause a system hang or a data
              corruption during backup.

          Smartdrive (from Windows 3.1) - By default SMARTDRV.EXE will
              cache both reads and write to a hard disk.  The caching
              of the writes is incompatible with Back-It 4.  Either
              change the C:\windows\smartdrv.exe command in your
              AUTOEXEC.BAT file, or place the following command in a batch
              file that executes Back-It 4.
              e.g.C:\windows\smartdrv.exe C D E /C 
              Where C D and E represent hard drive partitions and the
              /C flushs the write buffers to disk.

          Other disk caching products have the same problem  as Smartdrive
              and must have the write cache disabled before running Back-It 4

          Qemm 6.0 - You may have to put a DMA=32 statment following the
              QEMM command in the CONFIG.SYS file.
              e.g.DEVICE=C:\QEMM\QEMM386.SYS RAM DMA=32
              On some systems you may also have to disable the STEATH mode.
              e.g.DEVICE=C:\QEMM\QEMM386.SYS RAM ST:M DMA=32
              The ST:M or ST:F must be removed.

          EMM386 from DOS 5.0 and Windows 3.1 - Like QEMM 6.0 needs a D=32
              e.g. DEVICE=C:\DOS\EMM386.EXE RAM D=32

          STACKS - The Stacks command must be in CONFIG.SYS file.
              e.g. STACKS=32,128   (takes 4k of memory)
              on most systems.  However if you are running Windows 3.1
              the stacks command must be as follows
              e.g. STACKS=32,256   (takes 8k of memory)
              This is because Back-It 4 is its own multitasking program.  It
              relies on hardware stacks to handle interrups.  If no Stacks
              command is present or stacks are set to 0,0 the system memory
              could become corrupt and result in data loss.  If you want to 
              reduce the number of stacks to 9,128 or 16,128 see the fix for
              DR DOS below.

          DR. DOS 5.0 and 6.0 - Even though DR DOS does not complain about
              the stacks command, DR DOS does not currently support the 
              stacks command.  A work around that usually works is to 
              set COMPATIBILITY MODE to Normal in Back-It 4.

          Back-It 4 is not designed to work with multitasking programs
              such a Windows and Desqview.  If you want a Windows backup
              inquire about Back-it for Windows.

          Even though Back-it 4 will run under OS/2 version 2 it does not
              back up the exteneded attributes.  Because of this you can
              only restore the backup to a DOS machine.  If you restore the
              files to an OS/2 system the files will not be seen because
              they have no extended attributes.

          WARNING!:  If Back-It 4 hangs while doing a backup to a non
              QIC 40 or QIC 80 tape drive you MUST do a small backup 
              to the tape with overwrite set to NO.  Failure to do this
              could result in the loss of a backup set.
              
          Back-It 4 will not work with Falcon DOS 3.1.

                                 FLOPPY ERRORS 
                                

          Back-It 4 may report certain errors that simply mean it has
          not been completely configured for your computer.  If you get an
          error message that doesn't seem to go away, check the following
          items first before calling our office:

               - Make sure your floppy disk configuration is properly
                 set for the drives you are using.

               - Use only new, high-quality, high-density diskettes
                 for high-density 1.2MB or 1.44MB drives.  The "cheap"
                 diskettes can't physically hold the amount of data
                 that the drive puts on the diskettes.

               - Don't use diskettes that you know to be damaged.  If
                 you are not sure about your diskettes, then ALWAYS USE
                 ADVANCED ERROR CORRECTION and use either NORMAL or
                 SUPER verification (this allows Back-It to catch and
                 screen out the damaged portions).


          You may have one of the following problems, all of which can be
          easily overcome:

     1) If the "Floppy Saver" activates Press a key BEFORE changing
          the floppy disk. 

     2) Back-It 4 thinks a formatted disk is not formatted:

          If, when using the "Restore" command, Back-It 4 says that the
          diskette you inserted in the drive may not be formatted -- and
          you know that it is -- then go back to the "Configure Floppy"
          command and make sure that both the drive type and format size
          are correct for the diskette in question.  It is common on AT's
          with 1.2MB drives to configure the drive as a 1.2MB format but
          then to try restoring from a 360K diskette.  In this case, change
          the format size to 360K.

     3) You get the "BAD TRACK 0" message even on new disks:

          This message can appear in the "Backup" or "Restore" commands.
          Before throwing away the offending diskette (or Back-It!),
          recheck your floppy drive configurations (as above).  And, if the
          problem persists, you may wish to put Back-It in the
          "Compatibility" mode with the "Configure Other" command.

     4) A diskette used on one computer won't work on another:

          This, unfortunately, is a hardware (and sometimes a DOS) problem.
          We have found that not all 1.2MB drives are alike; and, 360K
          diskettes formatted in a 1.2MB drive may not be readable in some
          360K drives.

          If you need to backup to 360K disks in 1.2MB drives (because you
          plan to restore the files on another computer that has only 360K
          drives, for example), use diskettes that have been preformatted
          by 360K drives if possible.  This will help reduce the incompati-
          bility problems associated with the differing drive types.  And,
          ALWAYS USE ADVANCED ERROR CORRECTION when backing up to the lower-
          density diskettes.

     5) These are the approximate times that Back-It 4 requires to fill
          standard floppy diskettes with the Verify Option set to "off": 
          360K - 17.5 seconds; 720K - 33 seconds;1.2MB - 28 seconds;
          1.44MB - 33 seconds.  If your computer takes longer to fill diskettes 
          during backup, you may consider the following:

          Slower times are normal if you are backing up lots of small files,
          or if the files on your disk are fragmented (i.e., the sectors
          comprising your files are scattered over the disk instead of
          being contiguous for each file).  If this is the case, Back-It
          will very quickly resume its normal high speed when it gets to
          larger files.  (We recommend that you periodically use OPTune to
          defragment and optimize your hard disks.)

          We have noticed that many computers, either due to the specific
          version of DOS or due to the floppy BIOS, do not format diskettes
          efficiently.  You will notice that Back-It 4 will operate slower
          on diskettes formatted with the DOS "FORMAT" command, but will speed
          up considerably when you use diskettes that Back-It 4 formatted
          itself.

          If this is the case, you may wish to reformat all your floppies
          with GZFORMAT, our format "TSR" program that can be used at any time.
          This program will produce safer formatted diskettes than DOS --
          and will do it quicker and with less fuss.  These diskettes are 100%
          compatible for all DOS purposes.  The ONLY differences are that
          more bad sectors are screened out (whereas DOS will let marginal
          sectors pass) and the floppies will allow Back-It 4 to operate at
          the highest speed possible.)
