VIAWD(4) BSD Kernel Interfaces Manual VIAWD(4)NAME
viawd -- device driver for VIA south bridge watchdog timer
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device viawd
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
viawd_load="YES"
DESCRIPTION
The viawd driver provides watchdog(4) support for the watchdog interrupt timer present on VIA south bridge chipset (VT8251, CX700, VX800,
VX855, VX900).
The VIA south bridge have a built-in watchdog timer, which can be enabled and disabled by user's program and set between 1 to 1023 seconds.
The viawd driver when unloaded with running watchdog will reschedule the watchdog to 5 minutes.

ICHWD(4) BSD Kernel Interfaces Manual ICHWD(4)NAME
ichwd -- device driver for the Intel ICH watchdog interrupt timer
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device ichwd
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
ichwd_load="YES"
DESCRIPTION
The ichwd driver provides watchdog(4) support for the watchdog interrupt timer present on all Intel ICH motherboard chipsets.
The ICH WDT counts down in ticks of approximately 0.6 seconds; the exact value depends on hardware quality and environmental factors. Sup-
ported watchdog intervals range from 2 to 63 ticks.
Note that on some ICH-based systems, the WDT may be present but disabled, either in hardware or by the BIOS. The ichwd driver attempts to
detect this condition and will refuse to attach if it believes the WDT is disabled.
