 31.Sh NAME
 32.Nm mlx
 33.Nd Mylex DAC-family RAID driver
 34.Sh SYNOPSIS
 35To compile this driver into the kernel,
 36place the following lines in your
 37kernel configuration file:
 38.Bd -ragged -offset indent
 39.Cd "device pci"
 40.Cd "device mlx"
 41.Ed
 42.Pp
 43Alternatively, to load the driver as a
 44module at boot time, place the following line in
 45.Xr loader.conf 5 :
 46.Bd -literal -offset indent
 47mlx_load="YES"
 48.Ed
 49.Sh DESCRIPTION
 50The

250.Sh BUGS
251The driver does not yet support EISA adapters.
252The DEC KZPSC has insufficient flash ROM to hold any reasonably recent firmware.
253This has caused problems for this driver.
254.Pp
255The driver does not yet support the version 6.x firmware as found in the
256AcceleRAID 352 and eXtremeRAID 2000 and 3000 products.
