Using the TokenDisk Diskette Diagnostic Program
Run the TokenDisk diskette Configuration and Diagnostic
Program for your installed 3C619C adapter when you need to
do the following:
■
Test for setup/configuration
■
Test for physical board problems
■
View adapter statistics
The diagnostic program tests the adapter, not the network.
Make sure to boot from DOS before running the diagnostic
program because the TokenDisk diskette is not a bootable disk.
Make sure that your PC has an 80386 or higher processor.
The 3C619C adapter must be connected to the network for all
tests.
