If you > disable the watchdog in BIOS, does ichwd still work? If I kill -9 watchdogd the system do reset itself so I think ichwd(4) really works even if BIOS setting is 'Disabled' (but I'm not sure if this method is right? Looking at the code I think the answer is probably "Yes" though) Cheers, - -- Xin LI <delphij@delphij.net> http://www.delphij.net/ FreeBSD - The Power to Serve!
