Hi,
My Supermicro X5DPL-iGM-O has a winbond w83627hf chip onboard that
includes a watchdog timer. I found a driver on freshmeat that points
here: http://www.freestone.net/soft/pkg/w83627hf-wdt.tar.gz
but this does not seem to work correctly on 2.4.23, even with my
modifications to the ioports and registers that Supermicro sent me. I
have tried to contact the developer, he hasn't responded. I also
located a post to linux-kerel quite sometime ago:
http://seclists.org/lists/linux-kernel/2002/Dec/att-4150/w83627hf_wdt.c
I haven't tried this driver just yet. The lm_sensors project seems to
include a driver for this chip as well, but not for the watchdog part.
The specifications Supermicro sent me for the watchdog function are
located here:
http://www.stinkfoot.org/wdt.txt
Any help would greatly be appreciated, I know this particular chip is
included with many motherboards.
That freestone piece of crap didn't work for me,
and looking at the code I'm not surprised.
I did a patch against the existing advantechwdt
since the newer advantechs use the w83627hf.

I think the advantechwdt.c should be renamed to w83627hf_wdt.c
to avoid confusion (or replaced with the w83627hf_wdt.c
you referenced above, that I didn't notice when
I did this).
Pádraig.
p.s. I needed to merge the info from a couple
of different winbond manuals to do the driver.
Note also the advantech manual describes the
wrong watchdog!
