My friend bought a G5 recently and and had to return it for something. Apple told them to keep the disks and just send the computer. It was a hard drive issue I guess, and they reinstalled Tiger for him. Well anyway, they sent him all the system disks again. He said I could have his old ones, but I didn't get to ask him any questions. What are the system disks? Would I be able to use them to install Tiger on my G4? Maybe a nice person with a G5 could list the system disks for me. Even if there's no tiger disk, couldn't I just use the restore disks? My G4 has a clean HD, so I would need to be able to boot off the disk...hmm.. Any help is appreciated! If I can't do this I'll just buy Tiger.
