Hey,

My Pismo won't boot with the hard drive plugged in to the motherboard.

Unplug it and I can boot to a question mark or to a OS CD. Plug it back in and all it will do is boot to a gray screen

I have tried many hard drives and bought a new hard drive cable. I have also tried unplugging the pram battery, all kinds of charging techniques and resetting everything in open firmware. Nothing helps. Any ideas?

Thanks for your time,
