NetBSD 6.1.5 - man page for pwdog (netbsd section 4)

PWDOG(4)			   BSD Kernel Interfaces Manual 			 PWDOG(4)

NAME
     pwdog -- Quancom PWDOG1 watchdog timer device

SYNOPSIS
     pwdog0 at pci?

DESCRIPTION
     The pwdog driver provides support for Quancom PWDOG1 boards.

     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.

     The timeout period of the PWDOG1 card is set using DIP switches and cannot be changed by
     software.

SEE ALSO
     intro(4), pci(4)

HISTORY
     The pwdog driver first appeared in OpenBSD 4.1 and NetBSD 6.0.

AUTHORS
     The pwdog driver was written by Marc Balmer <mbalmer@NetBSD.org>.
