Unplug the power switch for the PC from teh motherboard and plug the power-on cable from the M!-ATX in it's place.
I'd suggest reading the manual for botht he M1-ATX and the motherboard.
Hey up all. After a bit of help and advice. Currently I have to reach round and manually switch my PC on to get it booting up but I was thinking that it might be a good idea if it just booted itself up automatically when I switched the ignition. Is there any pro's/cons against this and how would I do it? I have the M1-ATX PSU and there's a pin to connect to the motherboard to allow this I think but dunno where on the motherboard to plug it into. The motherboard is a EPIA M1000 LVDS. Cheers all.
Doh! Why did I not think of that? Can't find the installation instructions for the motherboard and can't seem to get hold of a copy off the net. Thanks for that though.
