35.Cd device mlx
36.Sh DESCRIPTION
37The
38.Nm
39driver provides support for Mylex DAC-family PCI to SCSI RAID controllers,
40including versions relabeled by Digital/Compaq.

59.El
60.Pp
61All major firmware revisions (2.x, 3.x, 4.x and 5.x) are supported, however
62it is always advisable to upgrade to the most recent firmware
63available for the controller.

92rest of the array.
93.It mlx%d: system drive installation aborted
94.Pp
95Errors occurred preventing one or more system drives from being configured.
96.It mlx%d: new controller configuration found
97.Pp
98The controller has detected a configuration on disk which supersedes the
99configuration in its nonvolatile memory.
100It will reset and come up with the new configuration.
101.It mlx%d: FATAL MEMORY PARITY ERROR
102.Pp
103Firmware detected a fatal memory error; the driver will not attempt to
104attach to this controller.
105.It mlx%d: unknown firmware initialisation error %x:%x:%x
