Section 1
Using the 1GB Jaz "tools" Disk
The 1GB Jaz "tools" disk included with your Jaz drive is a
special dual-format disk which contains Jaz Tools software
for BOTH Windows/DOS and Macintosh systems. Before you can
write any files to the disk, the disk format must be set as
EITHER Windows/DOS (IBM-compatible PC) or Macintosh (which
eliminates files stored under the other format type).
Running the Jaz Tools software Setup program under Windows
3.1 or the Setup95 program under Windows 95 automatically
sets the "tools" disk format to Windows/DOS and reclaims the
Macintosh portion of the disk for use on PC systems.
Similarly, running the Iomega Install program for Macintosh,
sets the "tools" disk format to Macintosh and erases the PC
portion of the disk.
If you use your Jaz drive on both PC and Macintosh systems
and want to install Jaz Tools on both system types, you need
to purchase an additional "tools" disk for installing Jaz
Tools on your second system. (See your Jaz Accessory Guide
for ordering information.)
NOTE: The Jaz "tools" disk can be used to reinstall Jaz
Tools software on the SAME system type (PC or Macintosh) as
the initial installation. Be sure not to delete any of the
original files from the disk in case you ever need to
reinstall your Jaz Tools software.
_________________________________________________________
Section 2
Using the Guest Program
The Guest program allows you to use your Jaz drive on a
computer without having to permanently install either an
Iomega driver or Jaz Tools software. All you have to do is
connect the Jaz drive to the computer and to an Iomega Jaz
power supply, and then run the Guest program from one of the
"Install" floppies to load the Guest driver.
There are versions of Guest for Windows 95, Windows 3.1/DOS
and Macintosh systems:
* For Windows 95, run Guest95 from the Windows/DOS
"Install" floppy. If you encounter any problems, see
"Help for Guest95" on the "Install" floppy.
* For Windows 3.1/DOS systems, run GUEST.EXE from the
"Install" floppy. Refer to the GUESTHLP.TXT file on
the "Install" floppy for additional information on
using Guest with IBM-compatible PC's. (If you install
Jaz Tools software under Windows, you will find the
same information in "Guest Help" in the Iomega Jaz
Tools group.)
* For information on using Guest on Macintosh systems,
refer to "Guest Help" on the "Install" floppy for
Macintosh.
NOTE: On Windows 3.1, DOS, or Macintosh systems, running
the Guest program provides a temporary driver installation
that is removed when the computer is shut down or restarted.
Running Guest95 permanently installs the drivers needed to
support Iomega hardware under Windows 95.

Section 3
Installing Jaz Support on DOS-Only Systems
The SETUP.EXE program on the "Install" floppy disk for
Windows/DOS runs correctly only under Windows 3.1. If you
do not have Windows on your computer, you can still use the
Jaz drive, but you will not be able to use the Jaz Tools
software that requires Windows. This section describes the
software support for Jaz that is installed when you follow
the software installation instructions presented in the
printed "Jaz Installation Guide" for DOS systems that do not
have Windows.
______________________________
Section 3.1
Iomega Driver for DOS
Running the INSTALL program from the DOSSTUFF directory on
the Jaz "tools" disk installs Iomega SCSI software to
support your Jaz drive. The Iomega SCSI Driver installs as
a device (SCSIDRVR.SYS) in the computer's CONFIG.SYS file,
and because of the way DOS handles drive letter assignments,
this can shift your existing drive letters.
Iomega software for Jaz includes a TSR version of the Driver
(GUEST.EXE) which will not cause any drive letter shifts
when it is installed. Complete comparative information on
SCSIDRVR.SYS and GUEST.EXE is contained in the electronic
"User's Reference Manual" (REFMAN.EXE) which is included in
the DOSSTUFF directory on the Jaz "tools" disk. If you
prefer using the TSR version of the Iomega Driver
(GUEST.EXE), you can manually install it in your
AUTOEXEC.BAT file. Refer to the "User's Reference Manual"
for manual installation instructions. (See Section 5 in
this file for detailed instructions on accessing the
electronic manuals.)
NOTE: Iomega SCSI includes optional CD-ROM support. Refer
to Section 6 in this file for additional information on
installing the Iomega CD-ROM driver.
______________________________
Section 3.2
Jaz Tools under DOS
Iomega SCSI software includes a set of utilities that run
under DOS. The Iomega SCSI Utilities handle a number of
tasks related to using removable SCSI drives and disks,
including Jaz drives and disks. You can use these utilities
to set software protection options on your Jaz disks, copy
data to or from Jaz disks, format Jaz disks, or lock the Jaz
drive so that you can install software to a Jaz disk.
You can run the Utilities in an easy-to-use menu mode or
from the DOS command line. To start the Utilities in menu
mode, go to the DOS prompt for drive C: (the drive where
your Iomega SCSI software is installed) and type:
cd \IOMEGA <Enter>
SCSIUTIL <Enter>
If you need help running the Utilities, press <F1> anywhere
in the Utilities. Complete reference information on the
Iomega SCSI Utilities is contained in the electronic "User's
Reference Manual" (REFMAN.EXE). (See Section 5 in this file
for information on accessing the electronic manuals.)
______________________________
Section 3.3
Installing a Jaz jet under DOS
The INSTALL program does not automatically detect the Jaz
jet SCSI PCI host adapter. If your Jaz drive is connected
to a Jaz jet card and you are installing on a DOS-only
system, you MUST manually install the ASPI manager for the
Jaz jet in the computer's CONFIG.SYS file to complete your
software installation.
Here's how:
1. Run the INSTALL program from the DOSSTUFF directory on
the Jaz "tools" disk. (If you need detailed
instructions, refer to the printed Installation Guide
that came with your Jaz drive.)
2. Open your CONFIG.SYS file and locate the DEVICE lines
for the Iomega SCSI configuration utility and driver:
DEVICE=C:\IOMEGA\SCSICFG.EXE
DEVICE=C:\IOMEGA\SCSIDRVR.SYS
3. Immediately BEFORE the device line for SCSICFG.EXE,
insert the following line to load the Jaz jet ASPI
manager:
DEVICE=C:\IOMEGA\ASPI2930.SYS
4. Save changes to CONFIG.SYS, exit the text editor, and
reboot the computer.

Section 4
Installation Troubleshooting
This section includes problem solving information for the
following problems:
4.1 Duplicate drive letters
4.2 No drive letter available for the Jaz drive
4.3 Guest does not assign a drive letter to the Jaz
drive
4.4 Other problems
4.5 Special Information for Users of Adaptec EZ-SCSI
_______________________________
Section 4.1
Duplicate drive letters
If you see two drive letters for your Jaz drive or other
drive you are using with the Guest driver (GUEST.EXE),
reboot the computer immediately. Using your Jaz drive when
duplicate drive letters are present on the system can result
in data loss.
After the computer reboots, do not load the Guest driver.
You do not need to use Guest to access the Jaz drive on this
system because the Jaz drive is already being assigned a
drive letter.
Windows 95 Users: If you see multiple drive letters for your
Jaz drive or other Iomega drives, refer to the problem
solving information in the electronic "Installation Manual"
(MANUAL.EXE) that is included on the Jaz Windows/DOS
"Install" floppy diskette. (See Section 5 in this file for
information on accessing the electronic manuals.)
______________________________
Section 4.2
No drive letter available for the Jaz drive
You may see this problem when using the Guest program on
DOS/Windows 3.1 systems. For detailed problem-solving
information, refer to the GUESTHLP.TXT file which is located
on the "Install" floppy for Windows/DOS.
_____________________________
Section 4.3
Guest does not assign a drive letter to the Jaz drive
If you run the Guest program and it informs you that no
drive letters were added, and yet you cannot access the Jaz
drive, it indicates that the driver is unable to locate the
Jaz drive. This is probably due to a hardware installation
problem. For detailed problem-solving information for both
Windows 95 and DOS/Windows systems, refer to the electronic
"Installation Manual" (MANUAL.EXE) which is located on the
"Install" floppy for Windows/DOS.
_____________________________
Section 4.4
Other problems
If you encounter other problems while installing or using
Jaz Tools software or Iomega SCSI, refer to the electronic
"Installation Manual" (MANUAL.EXE) for additional problem
solving information. Section 5 contains detailed
instructions on accessing the electronic manuals.
_____________________________
Section 4.5
Special Information for Users of Adaptec EZ-SCSI
Jaz Tools and/or Iomega SCSI software can be used on the
same system as Adaptec EZ-SCSI without problems if you:
1. Use the Iomega SCSI driver to support your Iomega
drives. (If you are using Jaz Tools software under
Windows 3.1, you must run both Setup to install Jaz
Tools and Install to install Iomega SCSI. See the
electronic "Installation Manual" (MANUAL.EXE) for
detailed instructions.)
2. Use the /I option with SCSICFG.EXE to tell the Iomega
SCSI software to ignore devices you want controlled by
the Adaptec ASPIDISK.SYS device driver.
3. Use the /ID option with ASPIDISK.SYS to specify the
devices you want it to support.
NOTE: Without the /ID option, ASPIDISK.SYS will take
control of all SCSI devices, including your Iomega drives,
and you will be unable to use your Jaz Tools software or
Iomega SCSI Utilities.
The remainder of this section details how to use the /ID
option with ASPIDISK.SYS. For information on using the /I
option with Iomega software, refer to the electronic "User's
Reference Manual" (REFMAN.EXE). (See Section 5 in this file
for detailed instructions on accessing the electronic
manuals.)
To specify the devices you want supported by your EZ-SCSI
software, you need to add an ID option to the DEVICE line
for ASPIDISK.SYS in your CONFIG.SYS file. Here's an example
of an ASPIDISK DEVICE line:
device=c:\scsi\aspidisk.sys /d /pause
Leave at least one blank space after the last option on the
line and add an option of the form:
/ID=[SCSI ID#]+[SCSI ID#]+ ... +[Adapter ID#:SCSI ID#]...
Where each device you want ASPIDISK.SYS to support is
specified by its SCSI ID number. The adapter ID number need
not be specified if there is only one SCSI adapter in the
computer, or if the devices to be supported are connected to
the first SCSI adapter in the computer. (The adapter ID
number for the first SCSI adapter is 0; for the second
adapter the ID number is 1.)
For example, if you want ASPIDISK.SYS to control a SCSI hard
drive at SCSI ID 2 on the first or only SCSI adapter, you
would need edit the CONFIG.SYS file and add /ID=2 to the end
of the DEVICE line for ASPIDISK.SYS. (You would also need
to add /I=2 to the end of the DEVICE line for SCSICFG.EXE in
the CONFIG.SYS file to tell Iomega SCSI to ignore the SCSI
hard drive.)
The following example would tell the ASPIDISK driver to
support the devices at SCSI ID 0 and SCSI ID 1 on the first
or only SCSI adapter:
device=c:\dosstuff\aspidisk.sys /d /pause /id=0+1
Here are three other examples of command line syntax for the
ID option. The second and third examples assume that the
computer has two host adapters.
/id=0+4+6 Support devices at SCSI IDs 0, 4, and 6
on host adapter #0
/id=0+1:4+2 Support device at SCSI ID 0 on host
adapter #0. Support device at SCSI ID 4
on host adapter #1. Support device at
SCSI ID 2 on host adapter #0.
/id=0+1+2+1:1 Support devices at SCSI IDs 0, 1, and 2
on host adapter #0. Support device at
SCSI ID 1 on host adapter #1.

Section 5
Electronic Manuals
The Iomega software package for Windows/DOS includes two
electronic manuals:
* The "Iomega Installation Manual" (MANUAL.EXE) which
contains complete installation and problem-solving
information for Iomega software under Windows 95,
Windows 3.1, and DOS.
* The "User's Reference Manual" (REFMAN.EXE) which
contains complete reference information on Iomega
software for DOS/Windows 3.1, including the Iomega SCSI
driver (SCSIDRVR.SYS), the Guest driver (GUEST.EXE),
the Iomega SCSI Utilities, and the Iomega ASPI
managers.
To access the Installation Manual, insert the Windows/DOS
"Install" floppy in a floppy drive (the example below
assumes drive A:), go to the DOS prompt, and type:
A: <Enter>
MANUAL <Enter>
You can also run the Installation Manual from the Windows
File Manager by selecting drive A: and double-clicking on
MANUAL.EXE. Under Windows 95, you can access the
Installation Manual by double-clicking on the floppy drive
in My Computer and then double-clicking on the "Manual"
icon.
The User's Reference Manual is located in the DOSSTUFF
directory on the Jaz "tools" disk. Use the following
procedure if you need to access the reference manual before
installing your software:
1. Insert the "Install" floppy diskette for Windows/DOS
into the computer's floppy drive and the 1GB "tools"
disk into the Jaz drive.
2. Go to the DOS prompt and type:
a:guest.exe <Enter> (Install floppy in drive A)
or
b:guest.exe <Enter> (Install floppy in drive B)
3. Note the drive letter Guest assigns to your Jaz drive
and use it in place of "d:" in the following command
line:
d:\dosstuff\refman <Enter>
If you install Iomega SCSI software using the INSTALL
program, you can access the User's Reference manual from the
C:\IOMEGA directory after the software installation is
complete. Go to the DOS prompt and type:
c: <Enter>
cd \iomega <Enter>
refman <Enter>
If you install Jaz Tools for Windows using the Setup
program, you can access the User's Reference manual from the
JAZTOOLS directory on drive C after the software
installation is complete. Use the Windows File Manager to
locate REFMAN.EXE in C:\JAZTOOLS, and double-click on the
filename.
_________________________________________________________
Section 6
CD-ROM Support
Iomega SCSI software includes support for CD-ROM drives.
The Iomega SCSI CD-Player driver has been fully tested with
a wide sample of CD-ROM drives from different manufacturers,
and most drives showed full compatibility, working with both
data and audio.
Use the following procedure if you wish to install Iomega
SCSI CD-ROM support:
Step 1. Insert the 1GB "tools" disk into the Jaz drive.
Step 2. Insert the "Install" floppy for Windows/DOS into
the computer's floppy drive.
Step 3. Run GUEST.EXE from the "Install" floppy diskette.
Note the drive letter Guest assigns to your Jaz drive.
Step 4. Run D:\DOSSTUFF\INSTALL.EXE /2 (use the Jaz drive
letter in place of D:).
This procedure runs the Iomega SCSI Install program and
automatically installs the Iomega SCSI CD-ROM driver if the
CD-ROM drive is CONNECTED at the time of installation and if
the operating system is MS-DOS 6.0 or higher. If the CD-ROM
driver does not install automatically on your system, you
can install it manually after the Iomega SCSI driver is
installed. Refer to the electronic "User's Reference
Manual" (REFMAN.EXE) for information on installing the
Iomega SCSI CD-ROM driver manually.
NOTE: The Iomega SCSI Driver supports the Jaz drive, so you
will not need to use the Guest driver after Iomega SCSI is
installed. To speed up your computer's boot time, you can
remove or remark out the GUEST.EXE line in your AUTOEXEC.BAT
file.

Cautions
______________________________
Section 8.1
DOS DISKCOPY
CAUTION!
When used with removable disks (for example, Jaz disks,
Bernoulli disks, etc.), DOS DISKCOPY does not create a copy
of the source disk on the target disk. DOS DISKCOPY
executes as if copying data from the source to the target
disk; however, after completion, the target disk is
unreadable and must be reformatted. Use an Iomega disk
copying utility to copy disks (either Iomega SCSI Disk Copy
or Copy Machine).
______________________________
Section 8.2
Compression
Stacker 4.0 works with removable disks supported by
GUEST.EXE (for example, Jaz disks); however, do not reboot
when Stacker asks if you want to reboot to remove TSR's.
Rebooting removes the Guest driver and eliminates access to
the Jaz drive.
DoubleSpace and DriveSpace do not work with disks supported
by GUEST.EXE, but they do work with the Iomega SCSI driver.
If you want to use DoubleSpace or DriveSpace to compress
your Jaz disks or other removable disks, install the Iomega
SCSI driver in your CONFIG.SYS file to support your
removable drives. Refer to the Jaz Installation Guide for
IBM-compatible PC's for detailed instructions on running the
INSTALL program from the DOSSTUFF directory on the Jaz
"tools" disk. If you use Windows, also install your Jaz
Tools software for Windows by running the Jaz Tools Setup
program after installing Iomega SCSI.
CAUTION!
If you are using a compression utility on a removable disk
(for example, a Jaz disk), you should make that disk
nonremovable (or lock the disk in the drive) whenever the
compressed volume is mounted. Removing a disk while the
compressed volume is mounted could result in lost data. To
remove the disk, first unmount the compressed volume, then
unlock the drive. Refer to the electronic "User's Reference
Manual" (REFMAN.EXE) for detailed information on locking and
unlocking drives.
CAUTION!
Do not use any disk compression software to compress
removable boot disks.
Iomega SCSI Utilities with Stacker 4.0
When using Stacker 4.0 and Iomega SCSI, mounted, stacked
drives will not appear on the graphical user interface
screen for the Iomega SCSI Utilities. In order to use an
Iomega SCSI utility on a stacked drive, you must first
unmount the drive.
______________________________
Section 8.3
Shifting Drive Letters
The following caution applies only if you are installing Jaz
support on a DOS-only system or if you choose to install the
Iomega Driver, SCSIDRVR.SYS, in your CONFIG.SYS file.
CAUTION!
Installing the Iomega SCSI driver may cause your drive
letters (including network drives) to change. This could
affect Windows applications that reference existing drives.
Check your Windows groups and "ini" files. For additional
information, refer to "Relocating Drive Letters" in the
electronic "User's Reference Manual" (REFMAN.EXE).
Download Driver Pack
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.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
