I've a feeling this is/was in an assembled PC. Therefore there should be a bunch of wires running from the front panel of the machine. They're usually in pairs and will be things like the power LED, the HDD LED, the reset switch and the power switch. What is being refered to above is the power switch which will attach to the motherboard with a jumper like connection. The cable might have some label on it saying this is where it goes and the motherboard may also have this written on it. The motherboard manual is always the best way to identify this and can usually be downloaded off the web if you can identify the board manufacturer and model. If you test each of the power supply rails for shorts and don't find any it's probably safe to try powering up. Good luck :) RP -- Author: Richard Purdie INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
