[QUOTE="Jimbob101, post: 695735, member: 61808"] Hi All This is my first post on these boards. I repair logic boards and my hobby is bringing ibooks back from the dead. I have done 15 successful graphics chipset reflows and hope I can provide some help on the boards! :) Anyway. I have the bottom half of a G3 600mhz ibook sitting on my bench (with a vga screen attached and keyboard and mouse) which refuses to boot on its own accord! Here's what I have tried so far 1. I have stuck a new hardrive in with a fresh install of osx this is my "Test" drive so I know it works. I try to boot from this test drive but it wont boot I just get the flashing folder icon. 2.I have sucessfully booted from a G4 ibook (in target disk mode) which is connected to the G3 via firewire. And I can do everything on it surf the net etc. And what's [B]scary[/B] is that I can easily read and write to the "Test" drive!!! 3. I tried to boot an AHT cd for the G3 by using a firewire cd/dvd drive. I start up in disk manager and I can see the CD I try and boot and the screen flashes and kinda returns back to the startup manager page. 4. So relating to step 3 I put the AHT cd into the g4. I then connected the G4 to the G3 and went again to the startup manager on the G3 and I can see the AHT CD thats sitting in the G4 combo drive. I try to boot the disk and the same thing happens. 5. I have also tried just for kicks to boot the OSX install dvd from the firewire cd drive and it boots too. In summary: I can boot another computer (g4) via the G3 in firewire. And when doing this I can see the "Test" drive which is connected to the G3 logicboard. I can even read and write and play music from the test drive! But it just wont boot. I have tried other drives aside from my "Test" drive and they wont boot either. I have never come across a problem like this before? Its quite unusual but exciting at the same time Any thoughts?!
