Installing the UnixWare 2.1 Driver

SUMMARY

This document describes how to install and configure the mtok device driver for Madge Smart Ringnodes under Unixware 2.1.

The mtok driver for Unixware 2.1 supports the following Smart Ringnodes:

ISA Bus Ringnodes:

Smart 16/4 PC Ringnode
Smart 16/4 AT Ringnode
Smart 16/4 AT Plus Ringnode
Smart 16/4 AT PnP Ringnode
Smart 16/4 ISA Client Ringnode
Smart 16/4 ISA Client Plus Ringnode
Smart 16 Ringnode
Smart 16/4 ISA Client PnP Ringnode

EISA Bus Ringnodes:

Smart 16/4 EISA Ringnode

Microchannel Bus Ringnodes:

Smart 16/4 MC Ringnode
Smart 16/4 MC32 Ringnode

PCI Bus Ringnodes:

Smart 16/4 PCI Ringnode
Smart 16/4 PCI Ringnode (BM)

Please note that Plug&Play Ringnodes (i.e. Smart 16/4 ISA Client PnP Ringnodes and Smart 16/4 AT PnP Ringnodes) must be set to non-PnP mode using the MadgeWizard utility.

1. CREATING AN INSTALLATION DISKETTE

If you have received your Madge driver on an installation diskette then you should skip this section and proceed directly to section 2. This section describes how to create an installation diskette with the installation diskette image file mdgunx21.img from the Madge CD or bulletin board.

To create an installation diskette:

a) Log into your Unixware system as "root".

b) Copy the mdgunx21.img file into the /tmp directory.

c) Place a blank formatted 3.5inch diskette in the diskette driver and enter the command

dd if=/tmp/mdgunx21.img of=/dev/fd0

d) The diskette is now an IHV installation diskette for the mtok driver.

2. PRE-INSTALLATION

Please note the following points before you attempt to install the mtok device driver:

1. The Smart Ringnodes(s) for which you wish to install mtok must be physically present in your PC and be connected to a token ring network before you install mtok.

2. For ISA bus Smart Ringnodes you must know the hardware resource settings for which the Ringnodes have been configured. That is, the I/O locations, the IRQ numbers and for Smart 16/4 AT Ringnodes, Smart 16/4 AT Plus Ringnodes and Smart 16/4 AT PnP Ringnodes the DMA channels. For older Ringnodes with switches these values can be determined from the switches. For newer, switchless Ringnodes, these values may be determined with the Madge Wizard utility.

3. INSTALLATION

To install the mtok device driver for one or more Madge Smart Ringnodes that are already present in your PC and are connected to a token ring network proceed as follows:

1. Run the NIC Setup utility. This can be done from the graphical user interface by double clicking on the Admin_Tools/Networking/NIC_Setup icon. The utility can also be run from the command line whilst logged on as root with the command niccfg.

2. From the NIC Setup utility's menu screen choose the option:

Install driver from IHV diskette

When you are asked for an IHV diskette use the diskette created in section 1 above.

After the mtok device driver has been copied from the diskette a message will be displayed saying that the mtok driver has been added. Press ENTER to dismiss the message and return to the menu screen.

3. At the top of the menu screen there will be a list of all of the Network Interface Cards in the PC that Unixware knows about.

4. If you have none ISA bus Smart Ringnodes in your PC you should see them listed automatically at the top of the screen. (If you do not see them listed then you should exit the NIC Setup utility and re-run it.)

5. Since Unixware cannot automatically detect ISA bus adapters, ISA bus Smart Ringnodes will not be listed until you explicitly add them.

To add an ISA bus Smart Ringnode choose the option:

Add an entry for a card

You will be presented with a list of Ringnodes (and possibly other types of NICs) to choose from. Select a Ringnode from the list. You will then be asked to enter the hardware resource settings for the Ringnodes. Enter these. You will then be taken back to the menu screen.

6. When all of the Smart Ringnodes present in your PC are listed at the top of the menu screen choose the option:

Accept all entries

The NIC Setup utility will then install mtok for all of the Ringnodes listed.

7. You must now configure your network protocols e.g. TCP/IP and IPX. See the "SCO Unixware Installation Handbook" for details on how to do this.

8. Finally shutdown and re-boot your PC.

4. ADVANCED CONFIGURATION

Some advanced configuration of the mtok device driver cannot be done through the NIC Setup utility. There are two ways in which advanced configuration can be done.

4.1 By editing space.c

The file /etc/conf/pack.d/mtok/space.c contains C like definitions of various configuration parameters such as the maximum frame size and the source routing cache expiry time.

To change any of these parameters log on as root and edit the definition in /etc/conf/pack.d/mtok/space.c with a text editor such as vi. Then re-build the Unixware kernel with the command:

/etc/conf/bin/idbuild -M mtok

Finally shutdown and re-boot your PC.

4.2 With the device configuration utility (dcu)

The device configuration utility (dcu) can be used to change the hardware resources assigned to an adapter. If you have previously installed mtok for a Smart Ringnode and then you change one of the hardware resource settings on the Ringnode, you should use the dcu to change the hardware resources assigned to the Ringnode so that they match the settings on the Ringnode.

The dcu can be run from the graphical user interface by double clicking on the Admin_Tools/Hardware_Setup icon. The dcu can also be run from the command line whilst logged on as root with the command dcu. See the "SCO Unixware Installation Handbook" for details on how to use the dcu.

Normally ISA bus adapters that support DMA are configured to use DMA as this is the best transfer mode for Unixware. However, if you wish to force an ISA bus adapter to use programmed I/O (PIO), then use then use the DCU to change the DMAC value to a "-" character. When you re-boot the Ringnode will be forced into PIO mode.

5. TROUBLESHOOTING

Should something go wrong with the operation of the mtok device driver a message of the form:

WARNING: mtok0: xxxxxxxxxxxxxxxxxxxxxxxxx

will be displayed on the console. Most of the error messages are self explanitary - those that require explination are listed below.

(a) "adapter start failure - error 8/1"

This message indicates that the Smart Ringnode could not insert into the Token Ring. The most common causes are that the lobe cable is not correctly inserted or that the Ringnode has been configured to use the wrong ring speed.

(b) "adapter start failure - error 5/5"

This message indicates that mtok was unable to find a Smart Ringnode of the type specified in the NIC Setup utility. The most likely reason is that the wrong type of ISA bus Ringnode was chosen.

This message means that the Ringnode failed its DMA test. The most likely cause is that the DMA channel specified in the NIC Setup utility for an ISA bus Ringnode does not match the setting on the Ringnode.

This message means that mtok is failing to receive interrupts from the Ringnode. The most likely cause is that the IRQ number specified in the NIC Setup utility for an ISA bus Ringnode does not match the setting on the Ringnode.
