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.
