ADDENDUM TO
THE NETWARE INSTALLATION SUPPLEMENT
FOR 3COM ETHERLINK
AND ETHERLINK PLUS (REV 1.00)
You should use this addendum with the NetWare Installation Supplement for
3Com EtherLink and EtherLink Plus (revision 1.00, part #100-000348-001).
The information in this addendum applies only if you are installing EtherLink
II boards (series 3C503) in network stations on a NetWare v2.1x network.
This addendum explains how to set EtherLink II boards. These boards can
be used in IBM PC, PC XT, PC AT, or compatible computers, and in the IBM
Personal System/2 Model 30 computer. EtherLink II boards can be used in
workstations, file servers, and bridges; they can be used with thin cable,
thick cable, or a combination of the two.
Before you use this addendum, you should read Chapter 1 of the Netware
Installation Supplement for 3Com EtherLink and EtherLink Plus. Then follow
the instructions in this addendum to set your EtherLink II boards. After
you have set your EtherLink II boards, refer to "Inserting EtherLink
Network Interface Boards into Network Stations" in Chapter 2 of the
installation supplement to complete your installation.
NOTE: If you are installing NetWare ELS v2.1x, you should use the
ELSGEN installation utility, rather than NETGEN, to generate the
operating system.
LABELING ETHERLINK II NETWORK INTERFACE BOARDS
Before you can set your Etherlink II network interface boards, you must
decide which board to install in each workstation.
Refer to the sketch of the network that you made in Chapter 1 of the
installation supplement and to the worksheets that you filled out when you
generated the NetWare operating system or shell for each station. (The
worksheets came with the main NetWare installation manual.) Then, using a
string tag or some other form of identification, label each board with the
following information:
o The specific network station into which the board will be inserted
(for example, "Gloria's workstation by the main door").
o The kind of station into which the board will be inserted:
workstation, file server, or bridge.
o The configuration option (this includes the connector type, DMA
channel, interrupt line, base I/O address, and base memory
address). If the board will be installed in a file server or bridge,
label the board with the configuration option that you chose when
you generated the NetWare operating system. Boards installed in
the same file server or bridge cannot have the same
configuration option number. However, boards installed in
different file servers or bridges can.
If the board will be installed in a workstation, label the board
with the configuration option that you chose when you generated
the NetWare shell to be used in that particular workstation.
MAKING SETTINGS ON ETHERLINK II BOARDS
Configuration option settings for EtherLink II boards consist of the
following:
o Connector type
o DMA channel
o Interrupt line
o Base I/O address
o Base memory (RAM) address
Connector type, DMA channel, and interrupt line settings are determined by
the configuration option you selected in the NETGEN (or ELSGEN), SHGEN,
or BRGEN utility. You do not have to make these settings on the board.
Base I/O address and base memory address settings are made by mounting
shorting plugs on jumper blocks.
If you have configured the operating system (for file servers or bridges) or
the shell (for workstations) with an invalid option, your EtherLink II boards
will not work. You must reconfigure the operating system or shell by
running NETGEN (or ELSGEN), SHGEN, or BRGEN and selecting a valid
option.
NOTE: The Remote Reset feature allows workstations to boot from a
network (file server) disk. NetWare v2.1x does not currently support
this feature for the EtherLink II (series 3C503) board.
The following sections explain each of the configuration option settings.
CONNECTOR TYPE
EtherLink II boards have both a DIX connector and a BNC connector on the
metal mounting bracket. Use the DIX connector to connect to thick cable.
Use the BNC connector to connect to thin cable.
Options 0 through 15 are valid only with thin cable; options 16 through 31
are valid only with thick cable.
DMA CHANNEL
EtherLink II boards allow information to be processed either through DMA
(direct memory access) or RAM. If you selected DMA, you must set the
base memory address to DISABLE.
INTERRUPT LINE
The following configuration option table shows the interrupt line (IRQ) used
with each configuration option.

BASE I/O ADDRESS AND BASE MEMORY ADDRESS
To set the base I/O address and base memory address on Etherlink II boards,
complete the following steps for each board:
1) Identify the configuration option you should use by checking the tag
attached to the board.
2) Find the appropriate configuration option in the table located above.
3) Set the base memory address and base I/O address by mounting
shorting plugs on the appropriate jumper blocks.
COPYING ETHERLINK II DRIVER FILES FOR NETWARE VERSION 2.1x
If you are installing a NetWare v2.1x network containing EtherLink II boards, you
will need to copy the 3C503.LAN driver file from the driver update diskette to the
AUXGEN diskette you received with your NetWare shipment before you run the
following NetWare v2.1x installation utilities:
o NETGEN, used to generate the network operating system
o BRGEN, used to generate a NetWare bridge (if applicable)
o SHGEN, used to generate your workstation shells
1) Boot a computer with DOS.
2) Insert the diskette containing the new 3C503 drivers into drive A.
3) Use the DOS LABEL command to create a label "LAN_DRV_108" on the driver
update diskette.
4) Copy the EtherLink II 3C503.LAN file from the driver update diskette to the
AUXGEN diskette.
WHERE TO GO FROM HERE
When you have finished setting your EtherLink II boards, refer to "Inserting
EtherLink Network Interface Boards into Network Stations" in Chapter 2 of
the installation supplement.
