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