Drive letter assignments are controlled by the operating systemin order to change a drive letter assignment, you must work with the procedures required by your computers operating system.
If your computer is running Windows 95/98, you can change drive letters as desired for any of your removable drives (including your Zip drive and CD-ROM drive) by running the Guest program (guest9x.exe). Use the instructions below:
Make sure BIOS support for the Zip Internal drive is disabled in the computers CMOS setup. This may require turning off autodetection for the Zip Internal drive. Refer to the Owners Manual for the computer if you need instructions on getting into the CMOS setup and disabling autodetection.
NOTE: Some systems do not support DOS. This section describes how to switch in and out of the MS-DOS mode which is a start option for Windows 95/98. It does not apply to the DOS box (or window) that opens when you double click the MS-DOS Prompt icon within Windows 95/98. Use of the DOS box with the Zip drive works the same as it does with any other drive under Windows 95/98.
In order for the Zip drive to operate properly in Windows 95/98 DOS mode, you must perform a clean reboot when switching to or from DOS mode. Do not use the option from the Windows 95/98 Shut Down menu that reads: Restart the computer in MS-DOS mode. This option does not fully support the Zip drive at this time.
To switch to DOS mode:
c:\progra~1\iomega\tools\guest.exe
This procedure will provide access to any Iomega drives on the system. To return to the Windows 95/98 graphical interface again, restart the computer.
IMPORTANT! Do NOT type "WIN" at the DOS prompt after running GUEST.EXE as this will cause duplicate drive letters.
When copying disks in the Zip drive, do not use Microsoft DISKCOPY.EXE or the CopyDisk utility that is available when you right mouse click on the Zip drive icon. These utilities only work correctly with floppy drives.
Some software install programs must have a disk present in every drive connected to the system (including the Zip® drive) in order to run properly . If a disk is not inserted in the Zip drive during such an installation, you will see a "system Error" blue screen reading the Zip drive letter. Simply insert a disk in the Zip drive to continue the installation.
