     Section 1
     What is Guest?
     
     Guest is a portable driver program that lets you use your
     Jaz drive on a computer without having to permanently
     install the Iomega driver or Jaz Tools software.  There are
     versions of Guest for both Macintosh and PC systems.  Guest
     for IBM-compatible PCs running Windows 3.1 and/or DOS is
     described here.  If you are using Windows 95, refer to "Help
     for Guest95" on the Windows/DOS "Install" floppy.  For
     information on Guest for Macintosh, refer to "Iomega Guest
     Help" on the "Install" floppy for Macintosh.

     When you run GUEST.EXE, the Guest driver loads into the
     computer's memory and stays there until the computer is
     rebooted.  While Guest is in memory, it tells the computer
     how to talk to the Jaz drive and provides the Jaz drive with
     a drive letter. Guest allows you to read files from and
     write files to your Jaz disks.

     In addition to the Jaz drive, you can use Guest to support
     other Iomega drives, including Zip drives, 5.25 inch
     Bernoulli drives and LaserSafe drives, as well as non-Iomega
     removable SCSI drives, such as SyQuest drives and magneto-optical drives.

     NOTE:  When you install Jaz Tools software under Windows
     3.1, it installs the Guest driver program in the computer's
     AUTOEXEC.BAT file so that Guest loads each time the computer
     boots.  For more information, refer to Section 7, "Using
     Guest as a Permanent Driver."

     
     
     _________________________________________________________
     Section 2
     System Requirements for Guest

     To run GUEST.EXE, you need a compatible version of Windows
     and/or DOS.
  
       *  Compatible versions of Windows include Windows 3.1 or
          3.11, and Windows for Workgroups 3.1 or 3.11.
  
       *  Compatible versions of DOS include MS-DOS version 4.0
          or higher, PC-DOS version 4.0 or higher, and DR/Novell
          DOS version 6.0 or higher.  To check your version of
          DOS, use the DOS VER command.

     The drive you want Guest to support must be connected to the
     computer before Guest is loaded.  If the Jaz drive is
     connected to a non-Iomega SCSI adapter, check the
     information under Solving Problems in this help file before
     loading Guest.
     
     
     _________________________________________________________
     Section 3
     How to Load Guest
     
     Use the following procedure to load Guest to run your Jaz
     drive:

      1.  Connect the Jaz drive to the computer according to the
          instructions in your Jaz Installation Guide.

      2.  Insert the "Install" floppy disk for Windows/DOS in the
          computer's floppy drive.

      3.  If you are using Windows, you MUST exit Windows before
          loading Guest.  Select Exit from the Program Manager's
          File menu, and click on OK to end the Windows session.

      4.  At the DOS prompt, type either "a:Guest" (if the
          "Install" floppy is in drive a:), or "b:Guest" (if the
          "Install" floppy is in drive b:), then press the Enter
          key.  If you use Windows, you can restart Windows after
          Guest loads.

     If you encounter any problems, refer to Solving Problems in
     this file.

     Section 4.1
     Loading Guest into Upper Memory
     
     Guest can be loaded into upper memory using the DOS LOADHIGH
     command, provided an expanded memory manager (such as
     EMM386, QEMM, BLUEMAX, or 386MAX) is loaded on the computer. 
     Refer to your DOS User's Guide for detailed information on
     using the LOADHIGH command.
     
     
     ______________________________
     Section 4.2
     Express Loading Guest
     
     Each time the Guest driver loads, it must also load an ASPI
     manager so that it can communicate with the Jaz drive
     through the computer's SCSI host adapter.  To provide Guest
     with the flexibility to use a variety of host adapters, the
     "Install" floppy for Windows/DOS includes a complete set of
     Iomega ASPI managers.  As Guest loads, it tries to load each
     ASPI manager in turn until it finds one that allows it to
     talk to the Jaz drive (or other supported Iomega drives).

     Guest can load much more quickly if it does not have to use
     this trial-and-error process to find the correct ASPI
     manager.  If you use Guest routinely with one or two
     specific host adapters, you may want to edit the GUEST.INI
     file and remark out the ASPI managers you do not need.  Then
     Guest will try to load only the ASPI managers for the
     adapters you normally use.  

     Use the following procedure to customize your GUEST.INI
     file:

     Step 1:  Copy all files on the Jaz "Install" floppy for
     Windows/DOS to another disk.
     The "Install" floppy disk is permanently write-protected, so
     in order to edit the GUEST.INI file and use the new file to
     run the Guest program, you must copy the files to another
     disk.  You can copy the files to another floppy disk or to
     the hard disk on the computer where you will be using the
     Guest program.  If you need instructions on copying files,
     refer to the documentation that came with your Windows or
     DOS programs.

     Step 2:  Use a text editor to open the GUEST.INI file.
     Locate the GUEST.INI file on your copy of the "Install"
     floppy disk.  The GUEST.INI file is a text file, so you can
     use the Notepad in Windows, the DOS EDIT program, or any
     other ASCII text editor to edit it.  

     Step 3:  Identify the ASPI manager line Guest needs to load
     to support your Jaz drive.
     For example, if you routinely use Guest when your Jaz drive
     is connected to an Iomega PC1616 adapter, the Guest program
     needs to load the line that reads "ASPI=ASPI1616.SYS".  Use
     the following table to help you identify the ASPI manager
     line you need to load:

          Iomega Adapter                ASPI Manager

          Jaz Jet                       ASPI2930.SYS
          PC1616                        ASPI1616.SYS
          PC1600                        ASPIPC16.SYS
          PC800                         ASPIPC8.SYS
          PC2                           ASPIPC2.SYS
          PC4                           ASPIPC4.SYS

     Step 4:  Remark out each ASPI manager line you do NOT need
     to load by inserting "rem " at the start of the line.
     For the example where Guest is routinely used when the Jaz
     drive is connected to an Iomega PC1616 adapter, you would
     remark out all ASPI manager lines except the ASPI1616.SYS
     line:

               rem ASPI=ASPI2930.SYS
               rem ASPI=ASPIPPA3.SYS
               ASPI=ASPI1616.SYS
               rem ASPI=ASPIPC16.SYS
               rem ASPI=ASPIPC8.SYS
               rem ASPI=ASPIPC2.SYS
               rem ASPI=ASPIPC4.SYS


     Step 5:  Save the changes to the GUEST.INI file and exit the
     text editor.  If you are using an editor that has a variety
     of file formats, be sure to save the GUEST.INI file as ASCII
     text or DOS text.

     NOTE:  If you later need to use an ASPI manager which has
     been remarked out, simply edit GUEST.INI again and remove
     the "rem " at the start of the ASPI manager line, or use the
     original Jaz "Install" floppy diskette to run Guest.

     ASPI Manager Reference:  Detailed reference information on
     the ASPI managers used by the Guest driver is located in the
     electronic "Installation Manual" (MANUAL.EXE).  You can
     access the manual from the "Install" floppy for Windows/DOS
     by typing:

               A: <Enter>
               MANUAL <Enter>

     Section 5
     Solving Problems that may occur when using Guest
     
     This section describes solutions for the following problems:
     
       5.1     Guest does not assign a drive letter to the Jaz
                    drive
       5.2     Duplicate drive letters
       5.3     No drive letter available for the Jaz drive
       5.4     Using Guest with non-Iomega ASPI managers
       5.5     Drive C: no longer accessible
     
     
     _____________________________
     Section 5.1
     Guest does not assign a drive letter to the Jaz drive
     
     If you run GUEST.EXE and it informs you that no drive
     letters were added and yet you are unable to access the
     drive, then Guest was unable to locate the drive.  This is
     probably due to a hardware installation problem.  Check the
     following:

      *  Make sure the drive is correctly connected to the
     computer.  The Jaz drive must be connected to a SCSI host
     adapter supported by an ASPI manager which is installed in
     the CONFIG.SYS file or the GUEST.INI file.

      *  Make sure the drive is correctly connected to a working
     power supply and that power is ON.  The green power light on
     the front panel of the external Jaz drive will be ON when
     the power supply is correctly connected and the drive power
     switch is turned on.  The internal Jaz drive must be
     securely connected to a computer power supply cable as
     illustrated in the printed Installation Guide that came with
     the drive. 

      *  Make sure all data cable connections are STRAIGHT and
     SECURE.  Push the data cable for the external Jaz drive onto
     the drive's SCSI connector on until it locks in place.  If
     you are using the 50HD to 25D cable converter, tighten the
     connector screws firmly and evenly.  If you have an internal
     Jaz drive, make sure all Pin 1 connections are correct. 
     (Refer to the printed Installation Guide that came with your
     drive for detailed instructions on connecting cables.)

      *  If your drive is part of a SCSI chain, make sure that
     each device in the chain has a unique SCSI ID number (no
     duplicates).  If you need to change a SCSI ID setting, turn
     off power to the computer and all devices in the chain,
     change the conflicting SCSI ID, and power up again.

      *  Make sure the SCSI chain is properly terminated at each
     end and that termination is OFF for other devices in the
     chain.  If the external Jaz drive is the only or last drive
     on the SCSI connection, make sure the SCSI termination
     indicator light on the back of the drive is ON (indicating
     that the Jaz drive has termination actually on).  If
     termination is not on when it needs to be, move the
     termination switch on the back of the drive to the manual ON
     position ( | ).  If the Jaz drive is in the middle of the
     SCSI chain, termination should be off.  If necessary, move
     the termination switch to the manual OFF position ( 0 ). 
     (Use a pen point or straightened paper clip to move the
     switch.)
     
     
     After checking your hardware installation, rerun GUEST.EXE. 

     
     _______________________________
     Section 5.2
     Duplicate drive letters
     
     If you see two drive letter for your Jaz drive (or other
     drive you are using with GUEST.EXE), reboot the computer
     immediately.  Using your drive when it is assigned duplicate
     drive letters can result in data loss.  

     After the computer reboots, do not load GUEST.EXE.  You do
     not need to use Guest to access the drive on this system
     because it is already being assigned a drive letter.


     
     ______________________________
     Section 5.3
     No drive letter available for the Jaz drive
     
     If all drive letters available for physical drives are in
     use on the system, GUEST.EXE will be unable to assign a
     drive letter for the Jaz drive (or other drive you are
     connecting with Guest).  Use the DOS LASTDRIVE command in
     the computer's CONFIG.SYS file to increase the number of
     physical drive letters.  For example, adding the statement
     LASTDRIVE=M to CONFIG.SYS will provide drive letters for ten
     additional drives after drive C.  Use the following
     procedure to edit the CONFIG.SYS file:

     Step 1:  Use a text editor to open the CONFIG.SYS file. You
     can use the Notepad in Windows, the DOS EDIT program, or any
     other ASCII text editor.  The CONFIG.SYS file is located in
     the root directory on the computer's boot drive (drive C).

     Step 2:  Add the following line to the end of the CONFIG.SYS
     file.

               LASTDRIVE=M 

     This will provide ten additional drive letters for any new
     drives you want to add to your system.  If you do not need
     all of the drive letters between D: and M: for physical
     drives, you can use a letter earlier in the alphabet in
     place of the letter M; however, be sure you make enough
     spare drive letters available after E: to accommodate the
     drive you are installing and any other drives you may add to
     your system.  If your CONFIG.SYS file already has a
     LASTDRIVE statement, simply change the letter to one further
     down the alphabet.  Do not set the last drive letter to one
     close to the end of the alphabet, such as X, Y, or Z.

     Step 3:  Save the changes to the CONFIG.SYS file and exit
     the text editor. If you are using an editor that can save
     the file in a variety of file formats, be sure to save as
     ASCII text or DOS text.

     Step 4:  Reboot the computer.  Load GUEST.EXE after the
     computer boots.  

     NETWORK USERS:  You may have to relocate your network drive
     letter.  Ask your network administrator for help, or refer
     to the following instructions:
  
     Your first network drive letter will be the letter following
     the one used in the LASTDRIVE statement in your CONFIG.SYS
     file.  For example, if you used LASTDRIVE=m, the first
     network drive letter will be N.
     
     If your network drive letter has changed, applications you
     are running from the network (such as Windows or other
     applications that reference specific drive letters) may fail
     to work correctly unless they are reinstalled or adjusted
     for the drive letter change.  If you use a batch file to
     connect to the network, it will need to be adjusted to the
     new drive letter.  Your network login script may need to be
     revised if it refers to a specific drive letter for your
     network drive.
     
     Check the following:
     
      *  Edit the Path statement in your AUTOEXEC.BAT file to
     correctly reference your new network drive letter.
     
      *  Edit any batch files which load shells or applications
     from a network (including AUTOEXEC.BAT) to correctly
     reference new drive letter assignments.
     
      *  Edit your Windows "INI" files and your Windows groups to
     correctly reference your new drive letters.
     
      *  Check other application setup files.  Rerun the setup if
     drive letters cannot be edited.
     
      *  Check your user login script for references to specific
     network drive letters.  
     
     Reboot your computer and check your applications. 
     Applications that do not work with the new drive letter may
     need to be reinstalled.
     
     
     _____________________________
     Section 5.4
     Using Guest with non-Iomega ASPI managers

     The Guest driver utilizes ASPI managers to communicate with
     drives connected through a SCSI host adapter.  The "Install"
     floppy for Windows/DOS includes a set of ASPI managers for
     Iomega adapters.  If you are using a non-Iomega host adapter
     and ASPI manager software, you may need to edit the
     GUEST.INI file and add a line for the non-Iomega ASPI
     manager.  (If the adapter does not have an ASPI manager,
     Guest will not be able to operate.)

     Use the following procedure to edit the GUEST.INI file:
     
     Step 1:  Copy all files on the Jaz "Install" floppy for
     Windows/DOS to another disk.
     The "Install" floppy diskette is permanently
     write-protected, so in order to edit the GUEST.INI file and
     use the new file to run the Guest program, you must copy the
     files to another disk.  You can copy the files to another
     floppy disk or to the hard disk on the computer where you
     will be using the Guest program.  If you need instructions
     on copying files, refer to the documentation that came with
     your Windows or DOS programs.

     Step 2:  Use a text editor to open the GUEST.INI file.
     Locate the GUEST.INI file on your copy of the "Install"
     floppy disk.  The GUEST.INI file is a text file, so you can
     use the Notepad in Windows, the DOS EDIT program, or any
     other ASCII text editor to edit it.  

     Step 3:  Add a command line for the non-Iomega ASPI manager.
     Use the following syntax:  
     
     ASPI=<full path for ASPI manager><ASPI manager filename>
     
     The following line is an example for an ASPI2DOS ASPI
     manager which is located in the directory C:\ASPI:
     
               ASPI=C:\ASPI\ASPI2DOS.SYS
     
     If you do not know the path or filename for the non-Iomega
     ASPI manager, refer to the documentation that came with the
     adapter or ASPI software.
     
     Step 4:  Save the changes to the GUEST.INI file and exit the
     text editor.  If you are using an editor that has a variety
     of file formats, be sure to save the GUEST.INI file as ASCII
     text or DOS text.
     
     Step 5: Use your edited copy of the "Install" floppy disk to
     run the Guest program.

     ASPI Manager Reference:  Detailed reference information on
     the ASPI managers included with the Guest driver is located
     in the electronic "Installation Manual" (MANUAL.EXE).  You
     can access the manual from the "Install" floppy for
     Windows/DOS by typing:

               A: <Enter>
               MANUAL <Enter>


     _____________________________
     Section 5.5
     Drive C: no longer accessible

     If you are booting from an Iomega PC1600 or Adaptec adapter,
     the ASPI manager for the adapter must be installed in the
     computer's CONFIG.SYS file before GUEST.EXE is run.  If the
     ASPI manager is not installed in CONFIG.SYS when GUEST.EXE
     is run, Guest will load the ASPI manager via the GUEST.INI
     file, which will cause drive C: to no longer be accessible.  

     NOTE:  The ASPI manager for the bootable adapter must be
     loaded before any other ASPI managers in the CONFIG.SYS
     file.  If you need information on installing ASPI managers,
     refer to the electronic "Installation Manual" (MANUAL.EXE). 
     You can access the manual from the "Install" floppy for
     Windows/DOS by typing:

               A: <Enter>
               MANUAL <Enter>


     
     _________________________________________________________
     Section 6
     Required Files for Using Guest
     
     All of the files needed to load Guest are present on the
     "Install" floppy for Windows/DOS.  If you create additional
     floppies for loading Guest, make sure you include the
     following files:

               GUEST.EXE
               GUEST.INI
               ASPI2930.SYS
               ASPIPPA3.SYS
               ASPI1616.SYS
               ASPIPC16.SYS
               ASPIPC8.SYS
               ASPIPC2.SYS
               ASPIPC4.SYS

     Refer to Section 4.2, "Express Loading Guest," for
     instructions on customizing the GUEST.INI file to minimize
     the time it takes to load Guest.
     

     
     _________________________________________________________
     Section 7
     Using Guest as a Permanent Driver

     The Guest program, GUEST.EXE, is also the permanent driver
     program for the Jaz drive under Windows 3.1/DOS.  If you
     install Jaz Tools software using the Setup program on the
     "Install" floppy disk for Windows/DOS, it automatically
     installs GUEST.EXE in the computer's AUTOEXEC.BAT file. 
     This causes GUEST.EXE to run each time the computer boots. 
     If Guest can locate a Jaz drive (or other supported drive),
     it loads into the computer's memory and assigns the Jaz
     drive a drive letter.  If Guest cannot locate a supported
     drive, it does not load.

     If you use the Guest program frequently on a particular
     computer, you may want to install GUEST.EXE as a permanent
     driver on that computer.  If Windows is installed on the
     computer, the easiest way to permanently install Guest is by
     using the Setup program on the "Install" floppy disk.  If
     desired, you can select to install only the driver.

     To run the Setup program, insert the Jaz Windows/DOS
     "Install" floppy disk into the computer's floppy drive. 
     Load Windows and choose "Run" from the Program Manager's
     File menu.  In the Command Line box, type either "a:setup"
     (if the "Install" floppy is in drive a:) or "b:setup" (if
     the "Install" floppy is in drive b:), then click on "OK" or
     press the Enter key.

     If the computer does not have Windows, you can manually
     install GUEST.EXE in the computer's AUTOEXEC.BAT file.  For
     a detailed manual installation procedure, refer to the
     electronic "Installation Manual" (MANUAL.EXE) located on the
     "Install" floppy.

Download Driver Pack

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.
