Last week in my bofh-like work (#1) was about `portupgrade`-ing, getting stuff out of jammed printers and stuff...

At a time when i spent a pretty much time upgrading my '''m4d freecell skillz''', my eye (or feet?) laid on some forgotten old PC under the desk. I was too lazy to find someone with keys to storage room so I've decided make some backup server from it and keep it lying under the desk for future generations
*hh, owner will be pretty surprised when he finds out his machine is running OpenBSD*

Old AT PSU was dead so I switched it with some ATX one lying nearby (luckily mobo was AT/ATX combo).

Main problem arised when I tried to boot it up. Mobo didn't had (or at least I wasn't able to find it) any 'soft power-up' pins on it. *sigh* But solution came just few moments after.

Whenever you need to run ATX PSU without motherboard, short-circuit green cable with any of the black ones (ground).

I'm not sure of any side-effects of this, but machine already has uptime of few days.

BTW: you could also try use this solution to keep some older ATX systems without 'boot up after power loss' setting in BIOS running all the time. let me know if u've tried this one ^^
