Madge Networks Ltd. provides direct support for its third-party mtok device driver that runs in the Solaris operating environment. See the documentation accompanying your Madge Ringnode/Bridgenode for details on how to contact Madge for technical support.

Preconfiguration Information

Known Problems and Limitations

The following problems and limitations have been found with the Madge mtok driver. Contact Madge for technical support on these issues, as required.

• When the mtok driver is enabled, the following messages appear when the system startup scripts run ifconfig:

  configuring network interfaces: ip_rput: DL_ERROR_ACK for 29 errno 1, unix0 ip: joining multicasts failed on mtok0 will use link layer broadcasts for multicast

  These messages can be ignored.

• This release of the mtok driver does not support netbooting on Smart 16/4 Presto adapters.

• The adapter may fail to open on the ring if not connected to a properly configured network. Run the diag utility, which is supplied with the adapter, before using the adapter with the Solaris 2.6 operating environment.

Configuration Procedure

Configuring the Device

Various hardware settings on the adapter, such as the ring speed and DMA channel, can be set with switches on the adapter or using a configuration utility supplied on the MDGBOOT diskette shipped with your Ringnode. Refer to the documentation supplied with the Ringnode for detailed instructions.

When choosing hardware settings:

• Ensure that your Ringnode does not use the same IRQ as other adapters in your PC--and for AT Ringnodes, not the same DMA channel and I/O address.

• Make sure the selected ring speed matches that of the ring you want to connect to.

Note that a configuration utility must almost always be used to select features of the adapter (for example, ring speed). If the adapter isn't functioning properly, try alternate features, such as PIO instead of DMA, different I/O addresses, and so on.
