This document describes how to install and troubleshoot 
Madge Networks Smart 16/4 PCI (bm) Rev2 Token Ring adapters 
in a PCI PowerMac.

Prerequisits:

1. A PCI PowerMac running system 7.5 or later and OpenTransport 
   version 1.1.1 or later.

2. A Madge Smart 16/4 PCI (bm) Rev2 Ringnode.

Installing the adapter:

1. With your PowerMac switched off and disconnected from the 
electricity supply insert your Madge Ringnode into a PCI bus 
slot. Ensure that the Madge Ringnode is properly seated in 
the slot.

2. Connect an STP or UTP (but not both) cable to your Madge 
Ringnode.

3. Switch on your PowerMac.

Installing the driver:

On the diskette that contains this ReadMe! file there is an 
application called "Madge Driver Installer". Execute this 
application and follow the instructions.

Installing the driver manually:

1. On the diskette that contains this ReadMe! file there are 
two driver files called:

    Madge PCI (bm) Rev2 (16)
    Madge PCI (bm) Rev2 (4)

You should copy the appropriate driver for your Madge Ringnode 
into the Extensions  folder found inside the System Folder 
folder. Determine the correct driver to use with the following 
rule:

If your token ring network operates at 4 MBit/s then use one 
of the drivers whose name includes the term "(4)". If your 
token ring network operated at 16 MBit/s then use of the 
drivers whose name includes the term "(16)". If you are unsure
of the speed at which your token ring network operates check 
with your network administrator. Warning: using an adapter at
the wrong speed can cause serious problems on a token ring 
network.

Examples: 

    (i) If your  token ring network operates at 16 MBit/s. 
        Use the "Madge PCI (bm) Rev2 (16)" driver.

   (ii) You have 4 MBit/s. Use the "Madge PCI (bm) Rev2 (4)" 
        driver.

2. Restart your PowerMac.

3. If you select the "AppleTalk" control panel you should now 
see that "Token Ring" appears as one of the network choices.

Troubleshooting:

Problem: "Token Ring" does not appear as a network choice for 
         "AppleTalk".

Causes: (a) The Madge Ringnode is not properly seated in the
            PCI bus slot.
        (b) You have not selected the correct driver - see 
            above.

Problem: You cannot connect to a remote computer.

Causes: (a) The STP or UTP token ring lobe cable is not 
            properly connected to the Madge Ringnode.
        (b) You are running your Madge Ringnode at the wrong 
            speed. Ensure that you are using the correct 
            driver - see above.
