Guest is a portable driver program that lets you use your Zip drive on a computer without having to permanently install the Iomega driver or Zip 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, it 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 Zip drive and provides the Zip drive with a drive letter. Guest allows you to read files from and write files to your Zip disks. In addition to the Zip drive, you can use Guest to support other Iomega drives, including 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 Zip 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 you are using Guest with a Zip drive, the computer must have a compatible connection for the Zip drive model you are using.  The Parallel Port model of the Zip drive can be used on any IBM-compatible PC with a standard parallel port (printer port).  The SCSI model of the Zip drive requires a SCSI connection. On most IBM-compatible PCs, a SCSI host adapter must be installed in the computer to provide a SCSI connection. If the computer has 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 Zip drive: 1. Connect the Zip drive to the computer according to the instructions in your Zip 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 Advanced Loading Options ______________________________ 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 Zip drive through the computer's SCSI host adapter or parallel port. 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 Zip drive. 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. NOTE: Guest loads a single ASPI manager each time it runs. The ASPI manager selected will be the first one available in the GUEST.INI file that allows the Guest driver to communicate with a supported drive. Use the following procedure to customize your GUEST.INI file: Step 1: Copy all files on the Zip "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 Zip drive. For example, if you routinely use Guest when your Zip 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 Zip zoom SCSI accelerator ASPIPC16.SYS parallel port Zip drive ASPIPPM1.SYS PPA-3 adapter ASPIPPM1.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 Zip drive is connected to an Iomega PC1616 adapter, you would remark out all ASPI manager lines except the ASPI1616.SYS line: rem ASPI=ASPIPPM1.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 Zip "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: MANUAL _________________________________________________________ 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 Zip drive 5.2 Duplicate drive letters 5.3 No drive letter available for the Zip 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 Zip drive If you run the Guest program and it informs you that no drive letters were added, and yet you cannot access the Zip drive, it indicates that the driver is unable to locate the Zip drive. This could be due to a hardware installation problem or the result of two or more SCSI host adapters in the computer. Section 5.1.1 Solving Hardware Installation Problems Guest will not assign a letter to the Zip drive if the data cable connections are loose or incorrect, or if the drive is not receiving power. Check the following: * Make sure the Zip drive is correctly connected to the computer. A parallel port model of the Zip drive MUST be connected to an IBM-compatible parallel port (printer port). A SCSI model of the Zip drive MUST be connected to a SCSI connection (usually provided by a SCSI host adapter on a PC). If the Zip drive is connected to a non-Iomega SCSI host adapter, it must be supported by an ASPI manager which is installed in the CONFIG.SYS file or the GUEST.INI file. (See "Using Guest with non-Iomega ASPI managers" later in this file.) * Make sure the Zip drive is correctly connected to a working power supply. If you have an external Zip drive, try disconnecting the power cable from the Zip drive and then reconnecting it. (After reconnecting the power, check that the green power light on the front of the external Zip drive is ON.) If you have an internal Zip drive, it 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. If you have an external Zip drive, tighten the connector screws firmly and evenly on both the connection to the Zip drive and to the computer. (When connecting a parallel port Zip drive, the connection to the parallel port must be very tight on some computers before the computer will recognize the Zip drive!) If you have an internal Zip 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.) Check the Troubleshooting section in your Zip User's Guide for a detailed list of problem solving suggestions. Refer to your Zip Installation Guide for complete instructions on connecting the Zip drive. After checking your hardware installation, rerun GUEST.EXE. If you are using the SCSI model of the Zip drive and two or more SCSI adapters are present in the computer, you should also check the problem solving information in the next section. If your Zip drive is part of a SCSI chain, make sure that each device in the chain has a unique SCSI ID number (no duplicates), and that the chain is correctly terminated. Refer to the printed Zip User's Guide that came with your drive for more detailed SCSI Guidelines. If you are using the parallel port model of the Zip drive and the computer still does not recognize the Zip drive after you have thoroughly checked the hardware installation, the computer's parallel port may not be compatible with the Zip drive. Try installing the Zip drive on a different computer. If a different computer recognizes the Zip drive, the problem is probably an incompatible parallel port. If neither computer recognizes the Zip drive, contact Iomega Customer Service. Refer to the electronic "Installation Manual" (MANUAL.EXE) for a complete list of support numbers. You can access the manual from the "Install" floppy for Windows/DOS by typing: A: MANUAL Section 5.1.2 Two or More SCSI Adapters The Guest program may be unable to assign a drive letter to the Zip drive when there are two or more SCSI host adapters in the computer. To solve this problem, you need to edit the GUEST.INI file which is located on the "Install" floppy for Windows/DOS, and specify which ASPI manager Guest needs to use to access the Zip drive. Use the following procedure: Step 1: Copy all files on the Zip "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: Locate the ASPI manager line for the SCSI host adapter being used by the Zip drive. For example, if your Zip drive is connected to an Iomega PC1600 adapter, the Guest program needs to load the line that reads "ASPI=ASPIPC16.SYS". Use the following table to help you identify the correct ASPI manager line: Iomega Adapter ASPI Manager Zip zoom SCSI accelerator ASPIPC16.SYS parallel port Zip drive ASPIPPM1.SYS PPA-3 adapter ASPIPPM1.SYS PC1616 ASPI1616.SYS PC1600 ASPIPC16.SYS PC800 ASPIPC8.SYS PC2 ASPIPC2.SYS PC4 ASPIPC4.SYS Step 4: Remark out the ASPI manager lines not needed for the Zip drive by inserting "rem " at the start of each line. For example, if your Zip drive is connected to an Iomega PC1600 adapter, you would need to remark out all ASPI manager lines EXCEPT the ASPIPC16.SYS line: rem ASPI=ASPIPPM1.SYS rem ASPI=ASPI1616.SYS 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. Step 6: Rerun the Setup program from your edited copy of the Install floppy disk. NOTE: If you later need to install Zip Tools software on a different computer, use the original Zip "Install" floppy diskette. 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: MANUAL _______________________________ Section 5.2 Duplicate drive letters If you see two drive letters for your Zip drive or other drive you are using with GUEST.EXE, reboot the computer immediately. Using your Zip drive when duplicate drive letters are present on the system can result in data loss. After the computer reboots, do not load GUEST.EXE. You do not need to use Guest to access the Zip drive on this system because the Zip drive is already being assigned a drive letter. ______________________________ Section 5.3 No drive letter available for the Zip 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 Zip 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 a text file located in the root directory on the computer's boot 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, including your Zip drive. 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, make sure you provide enough drive letters after e: to accommodate your Zip drive and any other drives you may add to your system. If your CONFIG.SYS file already has a LASTDRIVE line, change the last drive letter to a letter further down the alphabet. Do not set the last drive letter to a letter late in 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 has a variety of file formats, be sure to save the CONFIG.SYS file 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 Zip "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 Zip 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= 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: MANUAL _____________________________ 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: MANUAL _________________________________________________________ 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 ASPIPPM1.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 Zip drive under Windows 3.1/DOS. If you install Zip 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 Zip drive (or other supported drive), it loads into the computer's memory and assigns the Zip 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 "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.
