2. Hardware requirements

Make sure that you have a Token Ring card that is supported by this driver. Currently the only cards that are supported are those that use the Tropic chipset.

Cards that I personally know to work are:

• 3Com 3C619B Token Link
• 3Com 3C619C Token Link
• HyperRing Classic 16/4
• IBM Turbo 16/4 ISA adapter**
• IBM Token Ring Auto 16/4 ISA adapter
• IBM Token Ring Auto 16/4 adapter /A
• IBM Token Ring 16/4 adapter /A
• IBM Token Ring adapter /A
• IBM Token Ring adapter II (4 Megabit only)
• IBM 16/4 ISA Token Ring card (16bit)
• IBM 16/4 ISA Token Ring card (8bit)
• Madge Blue (100% IBM compatable)

It is recommended that you use 16KB Shared RAM for the time being.

Cards that may cause problems:

IBM Turbo 16/4 ISA adapter

This adapter will, in fact, work fine with the Linux token ring driver. However, you MUST run the card in Auto 16/4 compatability mode. The simplest way to set this is to use the LANAID disks sent with the card and run the command:

LANAIDC /FAST=AUTO16
       

You should then use LANAIDC or LANAID to configure the card according to documentation.

Token-Ring Network 16/4 Adapter II

This adapter will NOT work. Do not confuse this card with the IBM Token Ring adapter II (4mbit) which does. It is a DMA/Busmaster adapter for ISA.

3Com TokenLink Velocity ISA

You may or may not get this one to work. I have had reports of people running it without problems, and others who get errors left and right.

PCI adapters

Currently, none of the IBM PCI adapters are supported.

IBM Auto LanStreamer 16/4 Token-Ring PCI Adapter

Currently not supported, but being worked on. This driver should be Full Duplex as well when completed.
