.Sh NAME
|
|
.Nm mlx
|
|
.Nd Mylex DAC-family RAID driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device pci"
|
|
.Cd "device mlx"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
mlx_load="YES"

.Sh BUGS
|
|
The driver does not yet support EISA adapters.
|
|
The DEC KZPSC has insufficient flash ROM to hold any reasonably recent firmware.
|
|
This has caused problems for this driver.
|
|
.Pp
|
|
The driver does not yet support the version 6.x firmware as found in the
|
|
AcceleRAID 352 and eXtremeRAID 2000 and 3000 products.
