This is actually a user-land change to the shutdown program. Upgrade 'shutdown' and use the '-o' option to power-off on shutdown.

This is a known problem that I've attempted to track down many times over the past year and a half, without success. I'm out of possible causes, and so far I haven't been successful in tracing my BIOS's APM code back to any type of evil instruction. <sigh> *BSD is said to work; I wasn't able to find any significant differences between the OpenBSD apm code and ours. --Scott @ @ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-oOO-(_)-OOo-=-=-=-=-= C.
