Go to System Preferences/energy saver. Click Options. See "restart automatically after power failure" and check that.
If you mean physically unplugging the machine and then plugging it back in, I doubt the above would work.
Using OSX 10.3.9 & 10.4.11 on a G4, G5 & Intel Macbook

Thank's for your help; I presume this means if the power supply is yanked during operation or because of a power failure. I've enabled this setting.
I am still curious if there's a method of turning on the supply and getting a reboot.
Best regards

I'd imagine that if you replaced the power button connection on the CPU power on pins of the motherboard with a standard jumper, that would create the same connection as your power button, and thus it'd be like the power button was pressed every time you start up the machine. However, I'm not sure whether that'd cause long-term issues with the power being constantly moved accross the pins like that... it'd be something worth checking into, if you really need a machine to do that, though. If not, then surely there's some sort of switch mechanism you could use instead, but it'll be outside of normal software configuration type stuff.
To make it work correctly, you'd probably have to find some sort of automatic switch that say connects just long enough for the computer to start up, and then disconnects (similar to what happens when you push the front power button).
Anyhow, it sounds like what you want to do can only be done with hardware, and hacking the hardware yourself at that.
Then again, if you plan to always have your machine on - then setting option as mentioned by jmgalvin should be plenty enough. Just don't power your mac down, ever, unless you plan on being there to start it back up immediately/soon after.![[wink]](/data/assets/smilies/wink.gif "[wink] [wink]")
And do note: I'm not suggesting that you DO any hardware hacking on your system, but just that it's the only way I could see you getting the exact thing you're looking for.
