+.Sh NAME
+.Nm ichwd
+.Nd Intel ICH watchdog timer driver
+.Sh SYNOPSIS
+.Cd device ichwd
+.Sh DESCRIPTION
+This driver provides access to the watchdog timer (WDT) present on all
+Intel ICH chipsets.
+.Pp
+The ICH WDT counts down in ticks of approximately 0.6 seconds; the
+exact value depends on hardware quality and environmental factors.
+Supported watchdog intervals range from 2 to 63 ticks.
+.Pp
+Note that on some ICH-based systems, the WDT may be present but
+disabled, either in hardware or by the BIOS.
+The
+.Nm
+driver attempts to detect this condition and will refuse to attach if
+it believes the WDT is disabled.
