100 Tagged queueing is supported on 'W' series adapters, 'C' series adapters
101 with firmware of rev 4.42 and higher, and 'S' series adapters with firmware
102 of rev 3.35 and higher.
104 Boards with certain firmware revisions may lock up under heavy load to
105 certain devices, especially if tagged queueing is used.
107 a problem with your adapter, contact Mylex technical support and ensure you
108 have the latest firmware for your controller.

203 Support in this driver for the wide range of MultiMaster
204 controllers and firmware revisions, with their otherwise undocumented quirks,
205 would not have been possible without his efforts.
