Configuring the AIX 4.1 driver for the PowerPC

Before you configure the driver, make sure that your Smart Ringnode is installed in your computer and that the lobe cable is connected.

If you have installed a Smart 16/4 PCI (BusMaster) Ringnode, proceed to common configuration.
If you have installed one of the Smart ISA Bus Ringnodes, proceed to setting resources for ISA Bus Ringnodes.

Setting resources for ISA Bus Ringnodes

Unlike PCI bus devices, ISA bus devices do not automatically tell AIX what hardware resources they require; so you must tell AIX. There are two ways to do this. You can either use a utility provided with MTOKDD to automatically configure MTOKDD for you or configure MTOKDD manually. For the older Ringondes with switches, that is, the Smart 16/4 AT Ringnode and Smart 16/4 ISA Client Ringnode, you must configure MTOKDD manually.

Automatic configuration of the MTOKDD driver

From the smit utility, choose the following sequence of options:

Devices
ISA Adapters
List Unused Madge Smart ISA Ringnodes

Smit invokes a utility that lists all of the unused Madge ISA Ringnodes present (some Ringnodes may be omitted if their bus I/O addresses clash with other devices in use in the computer). MTOKDD can be configured automatically for any Ringnode that is not marked as "** Cannot automatically install".

To automatically configure MTOKDD for a Ringnode select the following sequence of options in smit:

Devices
ISA Adapters
Automatically Add a Madge Smart ISA Ringnode

After a short pause a form will appear with a single field. This field specifies which of the Madge ISA Ringnodes present in the computer MTOKDD must be configured. To select a Ringnode, click on the List (or press F4 in character mode "smit") and pick a Ringnode from the list. Now press [Enter]or select DO and MTOKDD will automatically be configured for the selected Ringnode. Once you have completed this step proceed to the Common configuration section.

Manual configuration of the MTOKDD DRIVER

To manually configure MTOKDD for a Madge ISA Ringnode choose the following sequence of options in the smit utility.

Devices
ISA Adapters
Add an ISA Adapter

You are presented with a list of the ISA bus adapters for which a device driver may be configured. Choose the appropriate Madge Ringnode. AIX prompts you to confirm the location of the device. After a short pause, you are presented with a form describing how MTOKDD thinks the Ringnode is configured. Ensure that the values match the real configuration of the Ringnode. Finally, press [Enter] or select "DO". It is possible that the smit utility may display an error message indicating that your Ringnode wants to use a hardware resource that another device is already using. If this is the case, leave smit, change the configuration of your Ringnode with its switches or using trcfgc and repeat this step. Once you have completed this step proceed to the Common configuration section.

Common Configuration

To configure you Madge Ringnode for use by a communications stack, perform the following.

Select the following sequence of options in the smit utility:

Devices
Configure Devices Added After IPL

The driver configuration process will now run. Once this has completed your ringnode driver will be configured to work with your Madge Ringnodes.
If you wish to start the TCP/IP stack select the following sequence of smit options:

Communications Applications and Services
TCP/IP
Minimum Configuration & Startup

From the list of options that is displayed choose one of the token ring interfaces. You will now be prompted to fill in various details about your computer. Thes details include its internet address and network mask. Refer to the the IBM AIX documentation about these details.
