Systems Using Cable Select
--------------------------
Most systems do not use this feature. Unless you are sure that the
system that the Maxtor hard drive is being installed in uses Cables
Select, do not set up the drive with this feature enabled.

Maxtor hard drives support Cable Select - which allows the system
to identify Devuce 0 and Device 1 drives on the interface cable. If
your system manufacturer for specific procedures for installing hard
drives.

On Maxtor DiamondMax hard drives, the Cable Select is enabled by
installing a jumper on J48. When J48 is installed, remove the jumper
from J50.
