Hi people,

I'm looking for any hints about using the watchdog feature of the "AMD K6-2 3d NOW". Perhaps there isn't such a watchdog at all?!
I'm quite firm on doing this stuff on small µPs like PICs or 805x, but have no idea or register-specs according to AMD micro processors...
Perhaps anyone here can help me to enable the watchdog timer on the cpu listed above.

Thanks in advance!

watchdog features seem to be something that is intergrated onto a motherboard,not the cpu itself.
also almost all of the results where about kiosk watchdog features and they gave no clue about how to enable them...
sory i could be more helpful .

Like Charlie suggested, a 'Watchdog timer' is an IC soldered to the motherboard(it could also be an add-in card) - it is NOT part of the processor.
The purpose of a 'watchdog timer' is to automatically reset the system without any user intervention if it locks up....it can also be used to perform a different(but pre-defined) action.
It contains a digital counter which will count down to zero from a set value at a constant speed - if it times out(i.e. if it reaches zero) before the counter is reset, it will perform a pre-defined action(such as resetting the system).

This feature is targetted primarily at systems which need to run unattended - if the O/S or a Software locks up, the 'Watchdog timer' will reset/reboot the system once the counter has timed out, enabling it to get back to work without any user intervention.
