[Freeipmi-users] bmc-watchdog and the OS watchdog in BIOS

Hi All,

We've tried installing the bmc-watchdog utility in IBMx343 running FreeBSD. 
We've found out that it can interact with the built-in management processor. 
When the timer was set to 1 minute using bmc-watchdog -s command, the system 
restarted after the specified time. But this setting did not change the OS 
watchdog timer that was pre-configured using the BIOS utility. How are these 
two differ from each other?

I've learned some known issues on using bmc-watchdog as specified in the 

Setting the watchdog timer on the user space is incomparable with an 
independent hardware watchdog (is this the case of the built-in management 
processor on the IBM x343 box?). Hope to receive some lights from all.
