SUMMARY
=======

To configure an IBM PS/2 Micro Channel Architecture (MCA) bus computer with a
3Com EtherLink/MC 3C523 adapter for thick Ethernet, you must boot from the
Reference Disk and set the "Transceiver Type" option to "External
Transceiver(DIX)" for the Ethernet card.

This differs from the thick Ethernet configuration of an ISA standard computer
with a 3Com EtherLink II 3C503 adapter, where the line "Transceiver = External"
must be in the PROTOCOL.INI file.

The following steps can be used to make this modification:

1. Boot from the Reference Disk.

2. Choose the Main Menu option.

3. Choose Set Configuration, and go to the appropriate section. For example:

      SLOT5     3Com EtherLink/MC Ethernet Adapter
       Enable/Disable Adapter............Adapter Enabled
       I/O Address Range.................300 to 307
       Interrupt Level...................Channel 3
       Packet Buffer RAM Address Range...0C0000 to 0C5FFF
       Transceiver Type..................External Transceiver(DIX)

4. Set "Transceiver Type" to the following:

      External Transceiver(DIX)
           for thick Ethernet (with a 15 pin DIX connector)

      On-Board Transceiver(BNC)
           for thin Ethernet (with a BNC "T-connector")
