Ok guys, I know what I said earlier about not getting Tiger to install, but I got to thinking about it and I had an idea. After digging around on the Tiger Install DVD, I found my answer. Here’s what I did to get the installer to install on my Lombard:
First, I created a CD/DVD master image from the Tiger Install DVD using Disk Utility. Then, I mounted the image. Then I found the OSInstall.dist file in /System/Installation/Packages/OSInstall.mpkg/Contents on the image. Near the top of the file is a line that specifies a list of “badMachines”, or some such. In that list is “PowerBook1,1”, the model code for the PowerBook G3 Lombard. I simply modified that entry to read “PowerBook3,1”. I then unmounted the image and burned it to DVD-R. My Lombard booted right up the installation DVD as it had before, but this time I received no error messages regarding unsupported hardware.
So, there you have it! It turned out to be much simpler than I had expected. Now, I must admit that I have not performed the installation of Tiger yet, so I cannot yet verify that the installation will complete successfully, but I plan to install a new HD in the machine and test it out at least before going back to Gentoo. I really don’t think Tiger will perform very well on this old machine, but it’s fun to try it out. :)
Now, a note for Lombard users without a DVD drive: I would expect that you could perform the same operation on the CD version available as a special order from Apple.
