Just wondering if  anyone can help.  I need to run a freebsd box that is headless, keyboardless, mouseless, & that I will have no network access to. What I want to do is allow someone to push the power button and the
machine will halt. I've been searching and can't
really find any real answers. I am assuming it has to do with apm or acpi but, I can't figure out exactly how to get them to work.

Stirch,

On a freebsd system - wouldn't holding down the power button serve this purpose for you, instead of just pushing it once?

Regards,

Neil

No, I need to make correct shutdown, justl like after typing 'halt' on console.

you need a board which supports apm, acpi, and a power supply which does support it too.
Then a apmd can manage yor request.

definitely needs an extra hardware piece if you want
a clean shutdown. a halt signal may also be delivered from the serial port assuming you can configure the box before
leaving it alone. even from the parralel port, but it's getting
hairy. or have a quick script running in the background
monitoring some other io.

Or you may try remote serial like www.realweasel.com
they're a friendly business.
I still got a couple of their pci cards I'm not currently using.

Sorry for delay.

ahoffmann - I got some troubles with apm0 device, still can't make it function.

rrbf - I discuss such devices at my local BBS, and decide not to use them for some reasons.

the apm0 device is completely useless if you board and/or BIOS does not work propper, please check this first.
