1. Make sure the ASPI manager for your controller is loading.
2. Did GUEST report any information about your SCSI controller? If
GUEST reported information about the SCSI controller, the problem is
caused by cabling, SCSI termination, or SCSI ID. Reconnect the
hardware. If GUEST did not report information, it could not load the
ASPI manager for your SCSI adapter. This may be caused by a port
address or IRQ conflict. Refer to the SCSI adapter manual for
information on how to change these settings.
If the Green Power light on the front of the drive is lit, check the
items below:
1. Is the Zip Drive is receiving power? Make sure that you are using
an EPSON Zip Power Supply. Check all power cables and connections.
Make sure that the power supply is plugged in to a working outlet.
Q: Does the green light come on now?
If not, either the drive or the power supply are damaged. Contact your
computer dealer or EPSON at 1-800-922-8911.
Software Configuration and Options
----------------------------------
After verifying all steps above, use the following software options
are available to help solve and debug problems.
Is the Zip driver loading properly?
1. Verify the Zip driver software has been installed.
2. Two files are required to use a Zip drive. GUEST.EXE and the
appropriate ASPI manager for the SCSI adapter being used. (For your
convenience, the EPSON provides drivers for some common SCSI
adapters.) Verify that the following files are located in the ZIPTOOLS
directory:
ASPIPPA3.SYS - ASPI manager for the PPA-3 Adapter & Parallel Port Zip.
ASPIPC16.SYS - ASPI manager for the Zip Zoom & PC1600 adapters.
ASPI1616.SYS - ASPI manager for the Iomega PC1616 adapter.
ASPIPC8.SYS - ASPI manager for the Iomega PC800 adapter.
ASPIPC2.SYS - ASPI manager for the Iomega PC2x adapter.
ASPIPC4.SYS - ASPI manager for the Iomega PC4x adapter.
See the GUESTHLP.TXT file on the Windows/DOS Install diskette for help
using GUEST with a SCSI adapter.
3. Verify that the AUTOEXEC.BAT file contains a line to start
GUEST.EXE. For example: C:\ZIPTOOLS\GUEST.EXE
If you complete the steps above and there is still no drive letter for
the Zip drive, use the INFO command line switch in the GUEST utility
to debug the problem. The INFO switch causes GUEST to display the
ASPI information. Check what the ASPI manager reports. The following
steps outline how the GUEST driver operates, and how to determine
