If you say Y here, the LEDs on your machine will be used to provide useful information about your current system status.

If you are compiling a kernel for a NetWinder or EBSA-285, you will be able to select which LEDs are active using the options below. If you are compiling a kernel for the EBSA-110 or the LART however, the red LED will simply flash regularly to indicate that the system is still functional. It is safe to say Y here if you have a CATS system, but the driver will do nothing.
