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

.Sh AUTHORS
|
|
.An -nosplit
|
|
.An Julian Elischer
|
|
wrote a driver for the Multimaster cards that appeared in the
|
|
.Bx 386
|
|
patch kit. The driver was rewritten by
|
|
.An Justin T. Gibbs
|
|
to take advantage of new board features and work with the CAM SCSI framework in
|
|
.Fx 3.0 .
|
|
.Pp
|
|
Special thanks to
|
|
.An Leonard N. Zubkoff
|
|
for writing such a complete and well documented Mylex/BusLogic MultiMaster
|
|
driver for Linux. Support in this driver for the wide range of MultiMaster
|
|
controllers and firmware revisions, with their otherwise undocumented quirks,
|
|
would not have been possible without his efforts.
