Hi there, I've been trying to resurrect my brother's powerbook g4 15in 1.25 al <the hard drive failed> I've installed a new hard drive and I have the original TIGER 10.4.3 (includes xcode2 - 2Z691-5599-A) install disk that came with it. I boot with Option or C and and the install disk loads and gives me the various options. I've tried a few times ( partitioning the drive first, as mac os extended journaled, with disk utility or doing it via the installer options in case it makes a difference) but every time when it reaches 100% it goes into what I think is a kernel panic as the box with the "you must restart your computer" message appears over the top of the install screen and I have to follow orders!! Obviously there is no working os to reboot into. I've tried to find this specific problem on the forums but I have come up with nothing. I thought an AHT might be appropriate but that option doesnt come up on the startup manager screen (and I thought it would for this model and install disk) I assume the disk is ok as it appears to finish the install and it also does a check up on the disk before the installation actually begins, if im not mistaken. I have a couple of other macs which I could use to help it install. Although I haven't yet managed to get them talking via target mode this time around, i have done before, troubleshooting with the old hard drive installed. If anyone has any insight into this id love to hear from ya. Thanks in advance!
