+.Sh NAME
+.Nm pwdog
+.Nd Quancom PWDOG1 watchdog timer device
+.Sh SYNOPSIS
+.Cd "pwdog0 at pci?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Quancom PWDOG1 boards.
+.Pp
+If the kernel crashes, the watchdog timer is not reset and the system will
+reboot (assuming a proper connection is made between the PWDOG1 and
+the motherboard).
+Alternatively, the watchdog can be reinitialized via a userland process which
+ensures that process scheduling, not just kernel timeout processing, is still
+taking place.
+.Pp
+The timeout period of the PWDOG1 card is set using DIP switches and cannot
+be changed by software.
+.Sh SEE ALSO
+.Xr intro 4 ,
+.Xr pci 4
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 4.1
+and
+.Nx 6.0 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Marc Balmer Aq [email protected] .
