Here's the deal. My brother is using a 500mhz titanium powerbook, and wants to install panther. He has the cds. Unfortunately, the cd drive won't work. It makes a really loud scratchying sound when you put a cd in, but doesn't recognize the disk. (they are fine when you take them out; ie they still work in other players) Is there a way to install panther without the cd drive? He doesn't have an external drive, though he does have an external hdd and an ipod. Is there a way to make it boot from an image of the cd's on the hdd or ipod? Any other ideas? Thanks
