89AMI FastDisk Host Adapters that are true BusLogic MultiMaster clones are also
90supported by this driver.
91.Pp
92Tagged queueing is supported on 'W' series adapters, 'C' series adapters
93with firmware of rev 4.42 and higher, and 'S' series adapters with firmware
94of rev 3.35 and higher.
95.Pp
96Boards with certain firmware revisions may lock up under heavy load to
97certain devices, especially if tagged queueing is used. Should you encounter
98a problem with your adapter, contact Mylex technical support and ensure you
99have the latest firmware for your controller.
