Power up for the slug NSLU2

[currter]

I was wondering is there a way to modify the hardware of the slug
such that when power is restored to the device, it powers up without
having to press the power on button.  I want to be able to shut the
power down and restore it and have the slug come on-line like my
other devices (router, NDAS, printer, scanner, USB hub, etc.).
And if there is a way to modify the device, is it easy to do or is there
an alternative device I could invest in that can be upgraded with
your firmware.

I would want to have NSLU2 or some other device (NAS200 for
example) serve as a webserver instead of leaving a computer running
all the time.

Google is your friend "nslu2 power" and just the first entry to
http://www.nslu2-linux.org/wiki/HowTo/ForcePowerAlwaysOn is the one you
should go for.

There are several solutions :

I have choosen alternative 9. The drawback is that if shut down time is
too short it does not work.

There are lots of alternatives on that page. But Alternative 11 seems the best from an engineering POV. It retains all the protections already provided on-board, one can see exactly how it is trying to work, and it seems to be OK for very short power outages, brownouts, or other blips.

For the application I have in mind, I need something that will sit there 24/7 and recover itself from anything the electricity supply might throw at it. Other opinions on this ?
