What is Guest?

Guest is a program that makes it easy to install Iomega drives on any computer running Windows 95/98.  By using Guest, you can set up your Iomega hardware without having to run the Windows 95/98 Add New Hardware Wizard.  When Guest runs, it automatically configures and loads the driver needed by Windows 95/98 for your Iomega adapter, and tells Windows about the drives connected to the adapter.  It also loads the driver that allows your IomegaWare software to talk to other adapters on your system.

For convenient access Guest9x.exe is included on the IomegaWare "Install" disk.  Installing IomegaWare also places a shortcut for Guest in your IomegaWare program group and in the IomegaWare folder on your desktop.


Guest and IomegaWare Setup

The IomegaWare Setup program runs the Guest program to install the drivers needed by Windows 95/98 for your Iomega adapters and drives.  Guest works with Windows 95/98 to provide your Iomega drives with drive letters so that Setup can install the IomegaWare software package.


Guest for Other Systems

In addition to Guest9x.exe (the Guest program specifically designed for Windows 95/98), there are Guest programs available for Windows 3.1/DOS and for Macintosh.  Use these other versions of Guest if you ever need to use your Iomega drive temporarily on one of these systems.

Windows 3.x/DOS

For PCs running Windows 3.1 and/or DOS, connect your drive and run the Guest.exe program included on the IomegaWare “Install” disk:

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

2.	Insert the IomegaWare "Install" disk into the computer's appropriate drive.

3.	If you are using Windows, you MUST exit Windows before running Guest.exe.  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 d:Guest (if the "Install" CD is in drive d:), then press the Enter key.  After Guest loads, you can restart Windows.

Refer to Guesthlp.txt on the IomegaWare "Install" disk if you encounter problems or need additional information on using Guest.exe.

Apple Macintosh

You can load the Iomega Driver temporarily from any Iomega disk that is formatted for Macintosh:

1.	Shut down the Macintosh and connect your Iomega drive.

2.	Turn on power to your drive and insert a Mac-formatted disk.  (This procedure will work only if you use an Iomega disk that is formatted for Macintosh.)

3.	Start the Macintosh following your normal startup procedure.

NOTE:  Your Macintosh must be using Mac OS System 7 or higher (up to Mac OS 8.x).  If you install iomegaWare software on the Macintosh as well as on your PC, you can refer to the Iomega Guest Manual on the Macintosh for additional information.


Why Run Guest?

When you install the IomegaWare software package using Setup.exe, it automatically runs Guest to set up your Iomega hardware.  If Setup completes normally, you may not need to run Guest again unless you add or remove Iomega hardware from your system.

After the IomegaWare software is installed, you may want to run Guest when you:

  Connect a parallel port Zip drive …

  Add a New Iomega Adapter ...

  Adding Drives to an Iomega Adapter Connection


How to Run Guest

You can run Guest from the IomegaWare "Install" disk or from the IomegaWare program group folder on your computer's Start Programs menu.

Here's how to run Guest:

From the IomegaWare "Install" disk:

1.	Insert the IomegaWare "Install" disk into the computer's appropriate drive.

2.	Using My Computer or Windows Explorer open the IomegaWare “Install” disk.

3.	Find and then Double click the Guest icon:

From your Windows 95/98 Program menu:

1.	Click the Start button on the Windows 95/98 taskbar.

2.	Point to Programs and then IomegaWare.

3.	Highlight and select Guest.


Guest Does Not Assign a Drive Letter

If Guest does not assign a drive letter to an Iomega drive, there may be a hardware installation problem.  Check the following:

•	Make sure the drive is correctly connected to the computer.  A SCSI drive must be connected to a SCSI host adapter.  (Guest will install and configure driver software needed for Iomega adapters under Windows 95/98.  A non-Iomega SCSI host adapter must be correctly installed under Windows 95/98 before using Guest or Setup.)   A parallel port drive must be connected to the computer's printer port.

•	Make sure the drive is correctly connected to an appropriate power source and that power is ON.

•	Make sure all data cable connections are straight and secure.

•	If your Iomega drive is connected to a SCSI adapter card, make sure the adapter is correctly installed under Windows 95/98.  You may need to run the Windows 95/98 Add New Hardware Wizard to install the adapter.  (See Guest hangs or no drives are found for instructions on manually installing an Iomega adapter.)

•	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, shut down Windows 95/98, turn off power to the computer and all connected 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.

Refer to the printed Installation Guide that came with your Iomega drive for specific information on solving hardware installation problems.  After checking your hardware installation, rerun Guest or Setup.  If the problem persists, make sure there are enough unused drive letters between your last physical drive and your first network drive to provide for any Iomega drives you are adding.  Contact your network administrator for help if you need to move down your first network drive letter.


Resolving Adapter Conflicts

Guest will be unable to load the driver for an Iomega adapter if there is a conflict with another adapter in the computer.  To resolve the conflict, you must reconfigure the adapter settings in the System Control Panel under Windows 95/98, and then change the switch or jumper settings on the adapter card to match the new configuration.

Here's how:

1.	Quit Guest and/or Setup.

2.	Click the Start button on your computer Desktop and point to Settings, then click on Control Panel.

3.	Double click on the System icon and choose the Device Manager tab.

4.	Select SCSI Controllers, then the Iomega adapter you are using, then click on Properties.

5.	Choose the Resources tab and change resource settings as needed to eliminate any conflicts identified by Windows 95/98.  Refer to the documentation that came with your adapter for information on optional settings.

NOTE:  If you need to reconfigure a "plug and play" adapter, you must use the computer's ICU program to change the adapter settings.  Contact your computer manufacturer for information on how to resolve the conflict.

6.	Shut down the system, open the computer, and adjust the adapter's switch or jumper settings to match the resources set in the System Control Panel in step 5.

7.	Restart the system and rerun Guest or Setup.


Guest Hangs or No Drives Are Found

This is often due to an adapter installation problem.  Use the Windows 95/98 Add New Hardware Wizard  to manually install Windows 95/98 support for the adapter(s) you are using with your Iomega drives.

Here's how to manually install support for an Iomega adapter:

1.	Click Start, point to Settings, then click Control Panel.

2.	Double click Add New Hardware.

3.	Click Next until the Add New Hardware Wizard asks if you want Windows to search for new hardware.

4.	Click No, then click Next.

5.	Select SCSI Controllers from the list of hardware, then click Next.

6.	Click Have Disk and insert the IomegaWare “Install” disk into the computer’s appropriate drive.

7.	Select the drive letter that corresponds to the location for the IomegaWare “Install” drive and click OK.

8.	When the list of Iomega adapters appears, highlight the adapter you are using and click Next to continue.

9.	Click Finish.  Windows 95/98 will evaluate whether or not this adapter installation conflicts with other adapters on your system.

NOTE:  Make sure the adapter settings assigned in Windows 95/98 match the actual jumper configuration on the adapter!  Check the documentation that came with the adapter for information on adapter jumper settings.  If you need to change jumper settings on the adapter, shut down Windows 95/98 and disconnect power to the computer.

If Windows 95/98 does not find any conflicts with the current adapter settings, click Restart to reboot the computer.  After the system restarts, run Setup from the IomegaWare "Install" disk to install software support for your Iomega drives.

If there is a conflict with any other adapter, you must reconfigure the adapter to resolve the conflict or you will be unable to use drives connected to the Iomega adapter.


Assigning Drive Letters Using Guest

If you add or remove drives and run Guest to refresh your system you may find that drive letters change for other drives in My Computer and Windows Explorer.  Iomega has added functionality to Guest making it easy to reassign your Iomega drive to a specific drive letter.

When you run Guest, a list of available drive letters are displayed (including network drives).  Guest allows you to select which drive letter you want assigned to each drive attached to your system by selecting a new drive letter in the pull-down menu box just below the drive icon.

NOTE:  In order for Guest to function properly it is necessary to reboot your system after running Guest. You do have the option to reboot immediately or to wait, but the reassigned drive letters will only change after rebooting.


Fixing Drive Letters Masked or Hidden by Network Drives

Guest scans and detects any drive letters being used by a network drive and alerts you to any problems that you may encounter while using your Iomega drive.  If a problem is found, you will see your Iomega drive with a yellow exclamation mark over it identifying the drive being masked. To correct this problem, simply select a new drive letter for this drive in the pull-down menu box just below the drive icon.


Multiple Drive Letters

If you see more than one drive letter for a removable drive in My Computer or Windows Explorer, try the following problem solving suggestions immediately.  Using your drives when multiple drive letters are present may result in data loss.

•	Make sure that each device in the SCSI chain has a unique SCSI ID number (no duplicates).  If you need to change a SCSI ID setting, shut down Windows 95/98, turn off power to the computer and all devices in the chain, change the conflicting SCSI ID, and power up again.

•	Remove all real mode drivers (such as Adaptec's ASPIDISK.SYS or Corel SCSI's UNI_ASPI.SYS) from your CONFIG.SYS file and restart the computer.  After the system restarts, open the Windows 95/98 Device Manager and make sure the list of SCSI controllers includes all non-bootable SCSI adapters.  (A bootable SCSI adapter will not be listed if it is being controlled by the adapter’s BIOS rather than a SCSI driver.)  If a non-bootable adapter does not have a SCSI controller listed in the Device Manager, use Add New Hardware in the Windows 95/98 Control Panel to correctly install driver support for the adapter.  Use the Help included with Windows 95/98 if you need additional instructions.


Parallel Port Zip Drive
Connect a parallel port Zip drive ...

Guest makes it easy to connect a parallel port Zip drive to any computer that is using Windows 95/98.  Here's how:

1.	Use the Zip data cable to connect the Zip drive to the computer's parallel port.

2.	Connect the Zip drive's power supply.

3.	Run Guest to provide the Zip drive with a drive letter.


New Iomega Adapter
Add a new Iomega adapter ...

If you add a new Iomega adapter to your computer system, you can use Guest to install and configure the adapter instead of the Windows 95/98 Add New Hardware Wizard.  Here's how:

1.  Install the adapter in the computer.

2.  Connect any drives that will be using the new adapter.

3.  Start Windows 95/98.

4.  Run Guest to install and configure the adapter under Windows 95/98.


Refresh your drive icons
Refresh your drive icons ...

Any time you add drives to an Iomega adapter connection, you can run Guest to refresh your drive icons for the new configuration.


Real Mode

Real mode, also called MSDOS compatibility mode, is an operating mode used by Windows 95/98 with hardware that is supported by MS-DOS device drivers.  Real mode is slower than Protect mode, which is the preferred operating mode under Windows 95/98.


CONFIG.SYS ...

CONFIG.SYS is a file used on DOS-based systems to specify which devices to install and which installable device drivers to use.  The CONFIG.SYS file also contains commands that determine how DOS uses memory and controls files.

When a DOS-based system is upgraded to Windows 95/98, the MS-DOS device drivers should be removed from CONFIG.SYS so that they do not conflict with the 32-bit mini-port drivers used by Windows 95/98.
