Note:
If the ARCNET I/O address was changed from the default of
2E0, you must document this change. It is suggested that you create an
ARCNET.OWS file describing all ARCNET settings for this PC. Keep
this file in the BATCH subdirectory. Do not keep it in the FMS
subdirectory, because it may be deleted during the next PMI update. A
sample of a typical ARCNET.OWS file is included in this section,
under the ARCNET.OWS section.
ARCNET Base Memory Address
The ARCNET base memory address is the input/output address buffer
for the ARCNET board. Up to a 16 K block of memory is mapped to
the ARCNET board. Use any available 16 K block of memory that can
be set on the ARCNET board (refer to the ARCNET user’s manual for
available base memory address settings). Metasys system
documentation recommends default settings for some PC types. If
there is a conflict with other adapters using the same base memory
address, then an alternate 16 K memory block needs to be set on the
ARCNET board. A change in the METASYS.INI file is not required.
Example
Problem Description—Typical Metasys system error messages include
N1 Memory Failures and/or N1 Initialization
Failures. These are caused by the computer’s not recognizing the
16 K base memory segment block used by the ARCNET board.
Verification—To verify that the PC is communicating to the ARCNET
board, an N1 Signature test must be run. This test uses a DOS program
called Debug. In running this test, Debug reads the memory address
segment of the ARCNET board and responds with the N1 Node
address set on the ARCNET board. (Do not run the Metasys system
until after performing this test.)
