OfficeConnect Fast Ethernet NIC (3CSOHO100-TX)
DOS Configuration and Diagnostic Program Instructions Summary
Overview
--------
The OfficeConnect NIC has a DOS Configuration and Diagnostic program
that can be used to troubleshoot problems or change configuration
settings while in DOS.
The configuration portion of the program allows you to change the
configuration settings for the NIC. The diagnostics portion of the
program allows you to make sure that the NIC is installed correctly
and is functioning properly in your PC.
Use the DOS Configuration and Diagnostic program only if you encounter
problems with the 3Com NIC Diagnostics program that runs in Windows.
Starting the DOS Configuration and Diagnostic Program
-----------------------------------------------------
CAUTION: If your PC operates as a server, notify all users on your
network to save their work and log out of the network before running
the DOS Configuration and Diagnostic program.
Do NOT run the DOS Configuration and Diagnostic program from the
MS-DOS box in Windows.
To start the DOS Configuration and Diagnostic program in a PC running
Windows 95, Windows 98, or Windows NT 4.0:
1. Exit to the DOS prompt.
2. Insert the EtherDisk diskette in drive A.
3. Enter the following at the DOS prompt:
A:\3C76XCFG.EXE
To start the DOS Configuration and Diagnostic program in a PC running
Windows NT 3.51:
1. Exit Windows NT.
2. Reboot the PC using a DOS-bootable diskette.
3. Insert the EtherDisk diskette in drive A.
4. Enter the following at the DOS prompt:
A:\3C76XCFG.EXE
Using the DOS Configuration and Diagnostic Program
--------------------------------------------------
There are two ways to use the program:
1. From the DOS Configuration and Diagnostic Program main menu.
2. From the root directory of the EtherDisk diskette, by
typing the following command:
3C76XCFG [command keyword] [parameter list]
3C76XCFG represents the DOS Configuration and Diagnostic program name.
The brackets indicate that the command keyword and parameter list are
optional.
Typing 3C76XCFG without any arguments (that is, [command keyword] or
[parameter list]) invokes the program in full Windows mode. This
includes mouse support and context-sensitive help. Press [F1] for help
at any time.
Command Line Keywords
---------------------
You can use the first two characters of any command or parameter as a
shortcut. For example, 3C76XCFG HE RU means 3C76XCFG HELP RUN.
Also, the command keywords and parameters are not case-sensitive, so
CONFIGURE, configure, and Configure, for example, will all work.
CONFIGURE
Configures a NIC in one of three ways:
1. Automatically with the /auto parameter
2. Using a specified NIC configuration file
3. Using command line configuration parameters
ECHOSERVER
Enables a designated NIC to function as an echo
server.
HELP
Displays general or command-specific help information.
To get command-specific help, type:
3C76XCFG HELP [command keyword]
LANGUAGE
Invokes the program in full windows mode using a
specified external resource file. This option provides
support for multiple languages via a different resource
file for each language supported.
LIST
Displays a list of installed NICs and their recognized
NIC numbers.
RUN
Executes the diagnostic tests (which can also be specified
from a file) on a selected NIC and writes the results
to the screen, a file, or a printer.
Configuration
-------------
The NIC can be configured in either full-screen Windows mode or
in command line mode.
Full Screen Windows Mode
------------------------
To configure the NIC using full-screen windowing, type:
3C76XCFG [Enter]
Then select the Configure NIC option from the Install menu.
Command Line Mode
-----------------
Command Line Mode Defaults
--------------------------
Defaults: CONFIGURE has /AUTO and /ADAPTERNUM:1 as defaults.
So, for example, if only 3C76XCFG CONFIGURE is used, NIC
number 1 will be automatically configured.
ADAPTERNUM:N and /SLOT:S parameters can be used with any of the
CONFIGURE options that follow. They are both intended for use
whenever multiple NICs are present in the computer and
recognized by the DOS Configuration and Diagnostic Program.
/ADAPTERNUM:N specifies the number of the NIC to be configured for
PCI computers. Run the LIST command separately to determine the
NIC number to use here.
There are three different ways to configure the NIC using the
command-line mode.
1. Command line with auto configuration
2. Command line with explicit parameters
3. Command line with configuration file
Command Line with Auto Configuration
------------------------------------
Command syntax: 3C76XCFG CONFIGURE /AUTO
The /AUTO parameter configures the NIC media type
automatically. All other options settings are left unchanged.
NOTE: The program attempts to detect what media type is being
used. Therefore, connect to the network first and then run
3C76XCFG CONFIGURE /AUTO. The program configures the
media type for you.
Command Line with Explicit Parameters
-------------------------------------
Command syntax: 3C76XCFG CONFIGURE [ /BSIZE:N /XCVR:N /TR:N
/FULLDUPLEX:N /OPTIMIZE:N /LINKBEAT:N ]
Command line configuration parameters are used to configure the
NIC using only the option settings you specify. Some
parameters are for all NICs; some are for PCI NICs only. For
example, /BSIZE:N is a PCI-only parameter. In most cases, any
combination of parameters can be used. Therefore, it is possible
to modify only a few settings if needed.
/BSIZE
Boot PROM Size
Possible values - disabled
/TR (or /XCVR)
Transceiver
Possible values - 100BASE-TX, TP, 10BASE-T (same as TP)
/OPTIMIZE
Network Driver Optimization
Possible values - NORMAL, NETWORK, CPU
/LINKBEAT
Link Beat disable/enable (pre-10BASE-T standard only)
Possible values - disabled, enabled
NOTE: Try this setting ONLY if pre-10BASE-T standard hubs
are in use.
/FULLDUPLEX
Full Duplex disable/enable
Possible values - disabled, enabled
NOTE: Enable this setting ONLY when the NIC is
connected to a 100BASE-T or 10BASE-T hub that
supports full duplex. Otherwise, it will bring
down the network.
Command Line with Configuration File
------------------------------------
Command syntax: 3C76XCFG CONFIGURE /CONFIGFILE:filename
/CONFIGFILE:filename is used to configure a NIC with the
settings specified in an ASCII configuration file that can be
created and modified by any text editor. The filename can be
a fully qualified DOS filename including a path. A standard
format for the file must be used, as follows:
- Variable names and values match the wording in the
full-screen Configure window in most cases.
- Begin each variable/value line with an "at" symbol (@),
followed by a variable name, a colon (:), and the value.
Example: @Media type: 100BASE-TX
- Blank lines and other white spaces are allowed between
variable lines.
- Start any comment lines with a semicolon (;).
- The variable names allowed are:
Boot PROM size
Media type
Network driver optimization
Full duplex
Link beat
- The values allowed are the same as those shown in the
full-screen Configure window.
Example 1: @Network driver optimization:Normal
Example 2: @Media type:On-board Coax
Diagnostic
----------
Full-Screen Windows Mode
------------------------
To run the diagnostic tests using full-screen windowing, type:
3C76XCFG [ENTER]
Then select the Run Tests option from the Test menu.
Command Line Option - RUN
-------------------------
Command syntax: 3C76XCFG RUN [/TESTFILE:filename] [/RESULTS:[filename
| PRN | PRNHP]] [/ADAPTERNUM:N]
The RUN parameter executes the diagnostic tests on a selected NIC
and displays the results on the screen. The defaults are NIC
number 1 and Group 1 tests. The parameters below are all optional.
/TESTFILE:filename
Specifies a test file that contains a specific test setup
description.
/RESULTS:[filename or PRN or PRNHP]
Specifies an alternative location to store the test results.
This location can be a DOS path and filename, PRN printer port
(same as LPT1), or PRNHP, which is an HP LaserJet printer
connected to LPT1.
/ADAPTERNUM:N
Specifies the NIC number to be tested, in the case of
multiple NICs installed in the computer and recognized by
this program. Run the LIST command separately (see LIST in the
next section) to determine the NIC number to use.
Other Command Line Options
--------------------------
HELP
Command syntax: 3C76XCFG HELP [Command Keyword]
HELP is an on-line summary of commands. Without a command keyword,
it gives a summary of the command keywords. With a command keyword
specified, it gives the parameter choices for that particular command.
For example, 3C76XCFG HELP CONFIGURE gives details about the
parameter options for the CONFIGURE command.
LANGUAGE
Command syntax: 3C76XCFG LANGUAGE /LANGFILE:filename
LANGUAGE invokes the program in full Windows mode using a specified
external resource file. This option provides support for multiple
languages through a different resource file for each language supported.
/LANGFILE:filename is a required parameter with this command.
The filename is the name of the resource file that is loaded by the
program. The filename can be a fully qualified DOS filename.
NOTE: At this time, there are no alternative resource files included
on the EtherDisk diskette.
LIST
Command syntax: 3C76XCFG LIST
LIST displays a list of currently installed NICs (and their
assigned NIC numbers) that are recognized by this program. The
NIC number is then used as the N value for the /ADAPTERNUM:N
parameter when multiple NICs are installed. There are no
parameters associated with the LIST command keyword.
ECHOSERVER
Command syntax: 3C76XCFG ECHOSERVER [/ADAPTERNUM:N]
ECHOSERVER enables a NIC to function within an echo server.
/ADAPTERNUM:N specifies the NIC to be configured in the
echo server, in the case of multiple NICs.
