Subject: How to reset the OS Watchdog timer in IBM x343?
Hello,
I have been searching the internet as to how to enable the OS watchdog timer
mechanism in IBM x343.
I tried setting the watchdog timer at the BIOS utility, and what I wanted to
know is how to reset the timer so as not to reboot the system during normal
operation. The box is run by FreeBSD 6.2, and I can't just use the IBM director
and/or the IBM director client as basically, it won't run on the said OS.
Adding out-band management card will also not help as basically the box doesn't
support such.
I've learned that the built-in service processor can be accessed using the
SMbus driver, but said driver is only for Windows/Linux. However, there should
be a way how to access/control the watchdog timer either by using a BIOS
interrupt call or a service. I need to send a heartbeat to the watchdog to
continuously reset the timer.
Thanks and best regards,
Won
