Affected 16/4 Token Ring adapters can be identified by the
part numbers of the two EPROM modules on the card. If EPROM

You can also check for microcode level C24550 by running the
Token Ring diagnostics from the reference diskette. If level
C24550 is present, the affected EPROMs are on the adapter.
