In our quick test, a TokenTalk NB Card also failed the Confidence Test when the
test was launched from a hard disk. N&C QA provided us with the following
information:
Such results may occur if the Confidence Test launching instructions are not
strictly followed because of two inherent characteristics of the diagnostic:
1) The Confidence Test is destructive by nature; therefore, the Macintosh
must be restarted after running the test.
2) The Confidence Test expects the TokenTalk NB Card to be in an idle
state; therefore, the test must be run before the TokenTalk NB Card is
used. Any software using the TokenTalk NB Card will interfere with the
Confidence Test and cause the test to indicate that the card is bad.
(Once installed, Token Ring software may start using the TokenTalk NB
Card at startup. So, if one runs the Confidence Test after starting up
from a Token Ring software installed disk, the Confidence Test may
indicate that the card is bad.)
The trick is to restart from a disk that has no Token Ring software installed,
like the User Confidence Test disk, and to restart the Macintosh after running
the test.

dialog and the Apple TokenTalk NB User's Guide (page 18).
