Subject: Re: [Freeipmi-users] bmc-watchdog and the OS watchdog in BIOS
Hey Won,
I cannot speak for your particular hardware. I'm not sure if there is a
separate independent hardware watchdog.
I can say, the settings you make with bmc-watchdog may not survive
across a system reboot. It's very possible that after a system reboot,
the BIOS resets the watchdog values back to the system default, no
matter what you previously configured.

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?
