+.Sh NAME
+.Nm lom
+.Nd lights out management
+.Sh SYNOPSIS
+.Cd "lom* at ebus?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the LOMlite lights out management module
+found on Sun Netra t1 systems and the LOMlite2 module found on Sun
+Fire V100/V120 and Sun Netra X1 systems.
+Temperature readings, PSU status and fan status provided by the LOM
+are made available through the
+.Xr sysctl 8
+interface.
+The integrated
+.Xr watchdog 4
+timer can be configured through the
+.Xr sysctl 8
+interface as well.
+The watchdog timer supports timeouts between 1 and 126 seconds.
+If the watchdog is disabled, which is its default state, it will turn
+on the system's fault LED after the maximum timeout of 126 seconds.
+.Pp
+The
+.Nm
+driver will update the hostname stored in the LOM whenever the
+system's hostname is changed.
