PCI watchdog Timer Board

I recently purchased a PCI watchdog timer board for my ZM machine. I am looking for ZM to 'tickle' the timer board every 30 seconds or so to prevent the system from being rebooted. To do this, I need to issue a command: echo tickle > /proc/pcwd
Which zm*.pl would this command best be issued from?
Thanks

It would arguably make much more sense just to install the Linux Watchdog package. Also, many modern motherboards have a hardware watchdog anyway (i.e., any Intel chipset i810 & later, and others) so you simply need to load the right kernel module and start the watchdog daemon.

If you do want to put this in ZM, then I would suggest that zmwatch.pl would be the best place as it's a watchdog script anyway.

I'm wondering if you found a bug in ZM which caused you to purchase a watchdog board? Or is it just an extra level of protection, like putting the system on a UPS, setting the BIOS to restart on powerfail, installing on JFS, etc?

Doug,
I just bought the PCI watchdog for added security. I have a machine dedicated to ZM, so I want to ensure it's always working. Plus, winning the eBay auction for $10 doesnt hurt either!
