OS/2

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")
