Hi everyone, i wonder if I could get some help... I have an iMac G5 20" 1.8 which could not find the startup/ hard drive... I have bought a new hard drive but when booting up. It can only read the Install Disk and hard drive is nowhere to be found. I have reset the SMU and PRMU and had no luck at all. It started just a few days back and have used the hardware disk to verify everything, and the hard drive and logic board have all passed the tests. I don't know whether the disks are incorrect as I bought it from a friend who had all the packaging and disks. The manuals included state the Mac OS X is Panther but when it was still working, I noticed the version was 10.5 something... I would appreciate all your help as I have partitioned the disk on a macbook with all the correct options. Had to even remove the memory sticks with no joy. The diagnostic LED 1, 2 and 3 do light up, I don't know when the 4th one is due to light up. Would appreciate your help and many thanks in advance.
