3Com (R) Corporation EtherDisk (R) Diskette for the 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.
