Ethernet Adapter (260-5505/A/B) Installation Faxback Doc. # 5613 Refer to the README.DOC on the SUPERDISK diskette for a list of network operating systems supported by the Tandy Ethernet Adapter and for information on installing the software driver programs. You will use the Setup program on the diskette after installing the Tandy Ethernet Adapter in the computer. When the desired options have been selected, you will save the configuration to the non-volatile memory on the adapter. Note that the Setup Program must be used to enable the adapter's IRQ channel before you can run the Diagnostic Program. Use the Diagnostic Program to check the adapter and network cabling when installation and setup is complete. The adapter uses both jumper settings and software on the SUPERDISK diskette for configuration. First, you must verify the jumper settings or change them as required by your particular installation. Next, install the adapter the your computer and use the Setup Program to select configuration options. Finally, use the Diagnostic Program to check the adapter and cable installation. The following sections provide information for preparing the adapter for installation. ADAPTER INSTALLATION When the jumper settings are verified, you are ready to install the Tandy Ethernet Adapter in any computer expansion slot. Refer to the section in your computer's user documentation that describes how to install option boards. If you are installing multiple adapters, insert one adapter at a time and configure it using the Setup Program before inserting the next adapter. Instructions for installing and configuring more than one adapter are provided in the section, "Configuring additional adapters". WARNING: Make sure that the computer power is OFF and the power cord is unplugged from the AC power source before removing the computer cover. When the adapter is installed and the computer cover is back in place, plug in the power cord and turn the power ON. Continue to the next section to complete the adapter setup procedure. SOFTWARE CONFIGURATION You must use the Setup Program that is contained on the SUPERDISK diskettes to configure the Tandy Ethernet Adapter you just installed. The configuration you choose using the Setup Program must not cause a conflict with other boards installed in the computer. CONFIGURING A NEW ADAPTER The Setup Program allows you to choose configuration options for the Tandy Ethernet Adapter. When you choose a parameter to change, a pop-up menu will display the available options. After selecting the appropriate options, you must save the configuration in the adapter's memory. The adapter will remain configured even when the computer is powered off. MOVING ADAPTERS TO ANOTHER COMPUTER You can usually use the Setup Program in one computer to configure an adapter that will be installed in a second computer, such as a "diskless" workstation. The only requirement is that the adapter's I/O base address must not cause a conflict with any other option board already installed in the computer that is used for configurations. The Setup Program allows other parameters chosen for the adapter to conflict with existing option boards, however, the adapter must not conflict in the second computer. Set the adapter to the desired configuration and install it in the second computer. If you cannot predetermine adapter configuration that will avoid a conflict with other option boards installed in the second computer, select the Setup Program option that resets the adapter to the factory configuration. Remove the adapter and install it in the second computer (if that computer has a floppy drive). Perform the configuration procedure at the second computer as if the adapter is new. I/O BASE ADDRESS The Setup Program can only access the Tandy Ethernet Adapter when the I/O space occupied by the adapter does not conflict with the I/O space assigned to any other option board. In addition, the software driver you choose must use the same I/O base address parameter as the adapter. Refer to the section, "Modifying Software Drivers", to determine if the I/O base address used by the adapter requires a driver parameter change. Then, select either the factory-programmed I/O base address of 240 (hex), or an optional address, according to the following guidelines: ONE TANDY ETHERNET ADAPTER: If no existing boards are installed in the range 240 to 260 (hex), the Setup Program will access the adapter at pre-programmed 240 (hex) I/O base address. You should then use the Setup Program to change the I/O base address to 280 (hex), if no I/O space conflict will occur. At 280 (hex), the adapter can use most of the software drivers from the SUPERDISK without modification. You may need to modify a software driver if any other I/O base address, including the 240 (hex) factory default, is chosen. Refer to the "Installation Options" appendix for more information. MULTIPLE TANDY ETHERNET ADAPTERS: You must set each adapter in turn for a unique I/O base address other than 240 (hex). That way, as you install each succeeding adapter with its factory default of 240 (hex), no conflict will occur with preceding adapters. Note that the software drivers for each adapter must be modified to match that adapter's actual I/O base address. OTHER OPTION BOARDS: Verify that the I/O space assigned to the Tandy Ethernet Adapter does not conflict with I/O space already assigned to existing option boards. For example, the factory default I/O base address reserves all ad- dresses from 240 up to (but not including) 260 (hex). No other option board can be assigned I/O space within that address range or a conflict will occur. Resolve conflicts by selecting an optional I/O base address for the option board in conflict or the LAN adapter. SETUP PROGRAM MENUS The Setup Program menus are used to configure the Tandy Ethernet Adapter. The menus allow you to do the following: * Select one adapter to be configured from up to four adapters that may be installed. * Automatically select a set of "generic" settings, suitable for most com- puters, that you can modify. * Manually select configuration options (such as I/O base address and IRQ channel) for your specific installation. Choose from the options displayed for each menu by moving the cursor with the "arrow" keys to the desired option and press . Follow any screen in- structions that are displayed. Help is available by pressing the func- tion key. Press the key to cancel any screen and return to the previous menu. USING THE SETUP PROGRAM Make sure that network software is not running on the computer. If network software has been running on the computer, reboot the computer to ensure cor- rect functioning of the Setup Program. To start the program insert the SUPERDISK diskette that contains the Setup Program in a floppy drive. Change to the drive and directory that contains the Setup Program. Then, type: SETUP and press You will need to identify the adapter you just installed so you can select that adapter for configuration. If you installed a new adapter, it is listed on the menu as the "Board Type: 8003EB" with the default 240 (hex) I/O base address. If no adapter is listed on the menu, refer to the section called "Clear Configuration Jumper" in the "Installation Options" section. If it was necessary to use the clear-configuration jumper, the I/O base address of the adapter will be listed as 280 (hex). Check the parameters you choose against the configuration of other option boards. In some cases, the Setup Program will display a message when you select an option that conflicts with another board. Make sure that the parameters displayed will not conflict with another LAN board or existing option board. If more than one Tandy Ethernet Adapter requires configuration for the first time, refer to the section called "Configuring additional adapters". CONFIGURING A SINGLE ADAPTER For a single adapter installation, use the following procedure: 1. Select the adapter you just installed for configuration. 2. Change the adapter's I/O base address to any available location according to the guidelines provided. 3. Select the other configuration options for this adapter according to the screen instructions. 4. Save the configuration to the on-board memory. If only one adapter is to be installed, then the configuration procedure is complete. Exit the Setup Program and go to the section called "Completing the Installation". If you installed a ROM device, refer to the "ROM Configuration" section. CONFIGURING ADDITIONAL ADAPTERS If you need to configure multiple adapters, each adapter must be inserted in the computer and configured, one at a time, BEFORE inserting the next adapter. The adapters are shipped from the factory with the same default I/O base address of 240 (hex). Therefore, a conflict will occur if more than one adapter is installed at the same time. If I/O base address 240 (hex) is not available in your computer, refer to the "Installation Options" section for instructions on using the clear configuration jumper. To install more than one adapter, use the following procedure: NOTE When installing multiple adapters, do not use 240 (hex) for an I/O base address until you install the last adapter. 1. Save any work in progress and then turn the computer power OFF. Unplug the power cord, and remove the computer cover. 2. Install one adapter, replace the computer cover, plug in the power cord, and turn the computer power ON. 3. Using the Setup Program, select the adapter you just installed. 4. Select any available I/O base address for this adapter except 240 (hex). 5. Select the other configuration options for this adapter according to the screen instructions. Save the configuration to the on-board memory, then exit the Setup Program. Repeat this procedure until all adapters are installed and configured. Make sure that no parameter conflicts occur between the adapters. ROM CONFIGURATION If a ROM device is inserted at socket U1 and the jumper settings verified (as described in Appendix A), use the ROM configuration menu in the Setup Program to enable the ROM device, define the ROM size, and select a ROM base address. The ROM base address you select must not cause a conflict with memory space used by any other option board. Refer to Table 1 (in MEMORY) to locate available memory space for the ROM. Also, the ROM size you select with the Setup Program must match the ROM size set using jumpers at W9. Refer to the "Installation Options" section, Table A-2, for jumper information. To configure the ROM device, use the following procedure: 1. Install the adapter and use the Setup Program to configure the parameters as described in the preceding sections. 2. Select the ROM configuration menu. 3. Select a ROM base address, and set the ROM size (which will also enable the ROM). 4. Save the configuration to the on-board memory, then exit the Setup Program. Use the documentation provided with the ROM device to prepare the network software package. COMPLETING THE INSTALLATION With the adapter installed and fully configured, you are ready to check the installation and cable, install the software driver, and load the network software package. MODIFYING SOFTWARE DRIVERS The software driver for each installed adapter must use the actual parameters you saved in the memory for that adapter. The I/O base address, RAM base ad- dress, and IRQ channel used by each LAN adapter must agree with the values for those parameters that are used by the adapter's software driver. The method used to change the software driver parameters depends on the network operating system software you are using. The SUPERDICK diskette has a separate direc- tory for each software driver. An INSTALL.DOC file in each directory provides specific instructions on modifying the software driver. Below are guidelines which describe the method used to modify software drivers for the following operating systems: * NETBIOS/OSI Interface Program: Change with command line parameters. Refer to the INSTALL.DOC file in the directory of the SUPERDISK disk- ette. * NetWare v2.0a workstations: Use the NWPATCH program to modify parameters as appropriate for the driver and operating system version. Refer to the user.doc file in the directory of the SUPERDISK diskette for in- structions on using the program. * NetWare v2.1 servers and workstations: Select from the optional set of parameters provided with the network software. If none of the displayed parameter options are available, use the NWPATCH program. * 3+: Change with command line parameters. Refer to the INSTALL.DOC file in the <3PLUS> directory of the SUPERDISK, or the "3Com Driver Installa- tion" appendix, for more information. If you are using another network operating system, consult the documentation provided with the software for instructions on selecting optional parameters. LOADING NETWORK SOFTWARE When the adapter and cable are installed and verified, load the network operating system software on the computer. Use the instructions provided with the network software package. If an optional ROM was installed on the adapter, you may need to prepare the network software for ROM operation. Refer to the instructions provided with the ROM device and your network software. (DTC/jlc-03/28/94)
