Hi Al, Thanks for your reply. Yes, I think this is a protection to the BIOS (not normally writable) so as not to let malicious progs to easily change the settings.

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.
