Hello,

I'm using a motherboard including an hardware watchdog that I want to be
able to control, so that it can restart the server when frozen.
To do that, I have to do some In/out to some ports, which is not permitted
from Ring3.
I then need to have some Ring0 code, which may be a device driver.
I've been browsing the DDK, but I can't find anything related to this kind
of driver.
Could someone tell me which kind of driver is the best appropriated, and
tell me if a sample or some basic code is available somewhere ?
I've been browsing the samples, but they are mostly based on the fact that
the device can be found thru some enumeration, and this driver is purely
I/O,
not registered on the PCI bus, the USB bus or anything else. You have to
know
it is there to use it, no way to guess...

TIA,
Regards,
Paul
