The clkbrd device provides support for the clock board on Sunfire, Starfire, and Wildire UltraSPARC systems. This device also controls the main front panel LED. This LED can be made to blink based on the load average on most systems by setting the sysctl(3) variable machdep.led_blink to a non-zero value.
