# Upgrading from an earlier version of the AIX 3.2 driver

Before installing the new driver software you must first de-configure your existing driver.

To do this:

1. Close down any applications you may have running.

2. Use the following command to find out the name of your Madge Ringnode devices:
   lsdev -C | more

   You will see a list of device names in the left hand column and descriptions in the right hand column. There should be an entry for one or more Madge Ringnodes with device names "tok0", "tok1", "tok2" etc.

3. Stop the TCP/IP stack from using any Madge Ringnodes by entering the command:
   ifconfig XXX detach
   for each ringnode. "XXX" is "tr0" for a ringnode with device name "tok0", "tr1" for a ringnode with device name "tok1" and so on.

4. Stop any other protocol stacks from using any Madge Ringnodes. For example, if you have a DLC interface installed, remove any DLC bindings to your Madge Ringnodes. (This may be done from the Devices menu in the smit utility.)
5. De-configure any Madge Ringnodes with the following command:
   rmdev -l YYY -d
   for each ringnode. "YYY" are the Madge Ringnode device names e.g. "tok0", "tok1" etc.

6. Install the driver software.
