CONFIG.TXT File 3Com Corporation 3Com Megahertz LAN + Modem PC Card (3CxEM556 PC Card family) Configuration and Diagnostic Instructions Summary This document contains information on running the configuration and diagnostic utilities provided on the Installation Disk #2. Topics include: Overview Running DOS CONFIG under Windows 95 Starting the Configuration and Diagnostic utility Configuration Changes Diagnostic Tests Where to Get Additional Information Overview -------- The configuration portion of the program lets you change the configuration parameters for the adapter to accommodate a specific operating environment. The diagnostic portion of the Configuration and Diagnostic Program ensures that the adapter is installed correctly and functioning properly. The basic tests check the physical components, connectors, and circuitry of the adapter and require only that the adapter be installed in the computer. The Echo tests check the adapter's ability to transmit data on the network and require that the adapter be connected to a network. The computer containing the adapter to be configured or tested must be running DOS only. Running DOS CONFIG Under Windows 95 ------------------------------------------ You should run CONFIG.EXE from a DOS command Prompt. Restart the computer. When you see "Starting Windows 95" press the F8 key. At the menu, choose "Safe mode Command Prompt Only" (usually #7). If you do run CONFIG.EXE from within Windows 95, use it only to read the informational documentation. Do not use it to configure the adapter nor to run AUTOLINK.EXE Starting the Configuration and Diagnostic utility ------------------------------------------------- There are two ways to start the program: 1. From the CONFIG.EXE program, by selecting Configuration and Diagnostic Program on the main menu. 2. Manually, from the root directory of the Installation Disk #2, by typing the following command: CONFIG [command keyword] [parameter list] CONFIG represents the 3Com Configuration and Diagnostic Program name. The brackets indicate that the command keyword and parameter list are optional. CONFIG without any arguments invokes the program in full Windows mode. Command Line Keywords --------------------- The command keywords and parameters are not case-sensitive, so CONFIG, config, and Config, for example, will all work. CONFIG.EXE Configures an adapter using command line configuration parameters. Configuration changes --------------------- The adapter can be configured in either full screen windows mode or command line mode. Full Screen Windows Mode ------------------------ To configure the adapter using full-screen windowing, type: CONFIG [Enter] Select Configuration and Diagnostic Program on the main menu. Then select the Configure Adapter option in the Configuration and Diagnostic menu. Command Line Mode ----------------- While Command Line Parameters are included here for completeness, use of the Command Line Mode may produce anamolous results. Command Line with Explicit Parameters ------------------------------------- Command syntax: CONFIG CONFIGURE [ /AUTO /IOBASE:N /INT:N /TR:N /MODEM:N /OPTIMIZE:N /LINKBEAT:N ] Each parameter must be of the structure "/keyword:value" and contain no blank spaces. For example: /iobase:300 /int:3 Command line configuration parameters are used to configure the adapter using only the option settings you specify. In most cases, any combination of parameters can be used. Therefore, it is possible to modify only a few settings if needed. /AUTO The /AUTO parameter configures the adapter automatically based on the software's best estimate using interpreted system information. /IOBASE I/O Base Address Possible values - 200,210,220,230,240,250,260,270,280, 290,2A0,2B0,2C0,2D0,2E0,2F0,300,310,320,330,340,350,360, 370,380,390,3A0 /INT Interrupt Level Possible values - 3,5,7,9,A,B,C,F Using invalid Interrupt values will produce undesirable results. /TR Transceiver Type Possible values - AUTO, TP, COAX /MODEM Maximum Interrupt Disable Time Possible values - NoModem, 1200, 2400, 9600, 19200, 38400 /OPTIMIZE Network Driver Optimization Possible values - DOS, WINDOWS, SERVER /LINKBEAT Link beat disable/enable (pre-10BASE-T standard only) Possible values - ENABLE, DISABLE To DISABLE linkbeat, use the /LINKBEAT:ENABLE switch. To ENABLE linkbeat, use the /LINKBEAT:DISNABLE switch. NOTE: Try this setting ONLY if pre-10BASE-T standard hubs are in use. Diagnostic tests ---------------- Full Screen Windows Mode ------------------------ The diagnostic tests are only available in full-screen mode. To run the diagnostic tests, type: CONFIG [Enter] Select Configuration and Diagnostic Program on the main menu. Then select Diagnostic Tests option in the Configuration and Diagnostic menu. Where to Get Additional Information ----------------------------------- If the adapter fails any of the diagnostic tests, see the TROUBLE.TXT file in the \HELP directory on the Installation Disk #2 for troubleshooting procedures. The SUPPORT.TXT file in the \HELP subdirectory on the Installation Disk #2 provides information about obtaining product support for the adapter. 3Com and Megahertz are registered trademarks of 3Com Corporation.
