Xamiche is right man, unfortunately you had it plugged in the wrong way (I suspected, but didn't look too hard as I was at work when posting in your other thread).
The IDE bus can handle a device being plugged in the wrong way for a few seconds, but eventually it'll die...and I'm sad to say yours has indeed been fried :-(
There is an A1200 mobo on eBay.au at the moment...maybe time for an upgrade, given the excuse you now have? Tower conversion anyone? :-)
PZ.
