A1200 HD will not work!

[Amiduffer]

Hope someone can help.

I purchased 3.1 rom chips for my 1200, so I could upgrade to OS3.5, but, then the cable for my HD fried, and now, the ami will boot up with floppies ok, but if I hook up a HD, the screen stays blank, and you hear an awful high pitched squeel. What's your diagnosis?

Well, I guess it's the IDE controller that's dead.

I did get a new HD and cable, and it still does the horrible noise.

Can anyone point out where the IDE controller is, and how to fix it, if possible?  

Is there any reason nobody answers the Telephone at Software Hut or Mr. Hardware?

>I'd look into the PSU as someone already mentioned as well

What is a PSU, and where is it located?

The sound, as far as I can tell, is coming from the left side of the A1200.

Well, let's see, I've tried a few combinations, I booted from floppies, with, and without the Blizzard 040/50mhz with no problems. I tried booting with HDD and Blizzard, just to see if it's just lack of power from the stock A1200PSU, *squeal*, then just HDD and no Blizzard *squeal*. Yes, it isn't covering the 4 pins off to the side, I'm pretty sure it isn't upside down. What in particular, do you mean about "miss" two pins on either side??

Gad, I'd hate to lose this one!
