inevitable component in Sun Exx00 machines and provides serial ports, NVRAM and TOD amongst others which are handled by uart(4) and eeprom(4) respectively). This driver currently only prints out information about the chassis on attach and allows to blink the 'Cycling' LED (which is duplicated on the front panel) of the clock board just like fhc(4) does for the other boards. The device name for the LED is /dev/led/clockboard. Obtained from: OpenBSD Tested by: joerg
