You can create a Diagnostic diskette or CD to:
Confirm that the hardware is functioning. Determine resolutions to conflicts during installation. Perform a stress test on the ports.
For example, you may want to run the diagnostics stress test overnight to evaluate a possible problem.
You will need loopback plugs for each port that you want to test.
Copy the .iso file
to a temporary location. Burn the image to a CD-ROM.

An .iso file cannot be copied onto a CD but must be burned using an application
that burns the image to the CD. If you do not have an application available,
you can use this freeware application. |

To start the diagnostic, reboot your system with the Diagnostics CD in the drive and follow the instructions in the diagnostic.
Use the following procedure to create a bootable diskette.

This procedure requires one blank diskette. |
|
Copy the diskette image file to a temporary location.
Execute Rawrite.exe. When prompted for a file name, enter the diskette image file name; for example: 1800055c.i To run the diagnostic, you will need at least one loopback plug. A loopback plug was shipped with
the RocketModem IV. To build a loopback plug, refer to the
RocketModem IV Hardware Installation and Specifications Guide [Rev A].
To start the diagnostic, reboot your system with the diskette in the drive and follow the instructions in the diagnostic.
