I need to do a reinstall of OSX 10.4 on a PB 1.5ghz blah blah, the problem is that when holding down C from boot it doesn't want to load the CD. It goes into what looks to be a physical memory dump mode (no clue) or some sort of crash. I've used two seperate restore/system cds but it wont read either. Both were tested with two other PB and worked. The laptop does start up and loads fine so I'm not sure if it's hardware problem or software.
