PCNET (COAX) SELFTEST PROBLEM
The PCnet SELFTEST program will, under certain conditions, give a
false indication of failure when operated with Release 3.0 or
above. Only a few boards have experienced this problem, and can
be attributed to a build-up of tolerances of components used in
the construction of these boards. There is no components
associated with any range of serial numbers, so the problem may
be experienced with new or old boards.
If the following message is displayed after the Interrput
selection is made:
Select Interrupt 2 (Default), 3, 4, or 5> (n)
*Response to unexpected interrupt 0**
*No response from selected interrupt (n) **
1. Stop test and reconnect the system cable or terminator
plug to the BNC connector of the PCB.
2. Restart the test.
3. If test runs successfully, consider the board as having
passed Selftest.
4. To insure correct Network operation, Nettest should also
be run.
A note should be entered into the PCnet Users Manual under the
"SELFTEST" command description referencing the above information.
