I just received this B&W PM today. Everything works great! The problem I'm having is with the installation of a 2nd hdd I had lying around. It has mandrake linux on it and was set to dual boot linux/XP when i had the windoze machine. Yes, my mac has the U bracket needed for a second HDD. The problem is when it's installed and I boot the system i get a folder with the ?. I believe it's because the second HDD has the boot agent on there. I want to wipe and reformat but I'm not sure how since i can't get to disk utility. Also, I'm not sure where the control board is on the mobo so i can set the second HDD to slave. I believe that might make it boot so i can wipe and reformat. I tried googling for a diagram of the jumpers but i had no luck. All help is welcome!
