Winbond 83627HF chip
I believe BIOS has watchdog disabled otherwise it would have reboot the box. However, the timer just start counting.
Comparing to ipmi_watchdog, you can do this: modprobe ipmi_watchdog ... start_now=0 ...action=<> nowayout=1
So it is possible to load the driver without start counting.
Notice it is an else, so t is actually 0 already (i.e. expired or never start running): > + } else { > + outb_p(0, WDT_EFDR); /* disable to prevent reboot */
