Title: Specifying SLOT for ELink/MC or ELink/MC-TP in NetConnect Server
date: 03/18/91

Copyright 3Com Corporation, 1991.  All rights reserved.

The 3+ driver 2ETH523.SYS (contained on the Option diskette) is the
remote network driver that you install on your 3+NetConnect server.  When
there is one EtherLink/MC adapter installed in the server, 2ETH523.SYS
will find the slot where the adapter is installed during driver
initialization.  If there are two adapters installed (in slots 1 and 3),
then the ETH523.SYS driver will ALWAYS select the adapter in slot 1 and the
2ETH523.SYS driver will ALWAYS select the adapter in slot 3.

However, you may want the drivers to operate with adapters in slots other
than the default slots.  To fulfill that need, the SLOT parameter was
introduced in the version of 2ETH523.SYS dated 1/89 with file size 8810.
The SLOT parameter allows the user to specify which adapter (in which slot)
the driver should operate with.  For example, you can use SLOT to specify
that the ETH523.SYS driver uses the adapter in slot 3 and the 2ETH523.SYS
driver uses the adapter in slot 1.

Note:  You do not have to specify a value for the SLOT parameter unless
there is more than one EtherLink/MC in the computer.

If you use an Etherlink/MC or Etherlink/MC-TP adapter as the secondary
adapter in a 3+NetConnect server, you must specify the slot number on the
DEVICE statement for the remote network driver in the CONFIG.SYS file.
For example, to use the adapter in slot 5 as the secondary adapter, type:

     DEVICE=2ETH523.SYS /SLOT:5
                 or
     DEVICE=ETH523.SYS /SLOT:5

Using the SLOT parameter solves the problem that occurred when an IBM Token
Ring microchannel adapter was being used as the primary network adapter and
an EtherLink/MC was being used on the secondary network adapter.  The
2ETH523.SYS driver never found an adapter to use, because 2ETH523.SYS
was searching for the SECOND adapter in the system, but there was only one
Etherlink/MC adapter present.  The SLOT parameter allowed the 2ETH523.SYS
driver to assume that the slot pointed to contains the secondary adapter,
regardless whose primary adapter is being used.

For more information on using 2ETH523.SYS, please refer to the 3+NetConnect
User's Guide and the 3+Installation and Setup Guide.
