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 <ENTER>. Follow any screen in-
structions that are displayed. Help is available by pressing the <F1> func-
tion key. Press the <ESC> 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 <ENTER>
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 <NETBIOS> 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 <NWPATCH> 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.
