Via Epia watchdog linux driver

[Juan Eliseo Carrasco Diaz]

 I have seen that the VT1211 chip (my epia PD6000E motherboard include 
it) support watch dog timer, but I can't find any watchdog kernel driver 
that support it. I have tried all the watchdog kernel modules without 
success (softdog.ko works with every PC because it's software).

 The last version of OpenBSD support it:

 I downloaded the viasio.c and viasioreg.h files from 
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/isa/ to see what they 
do and try to create my own linux watchdog module but I don't know how.

 Somebody know?

 Somebody can get the VIA VT1211 datasheet?

 Thank you!
