I have a Mac Mini running Tiger OS 10.4.11. Recently, I decided to get a refurbished PowerBook to upgrade to Tiger. Got a G3 Pismo equipped with firewire which is now running OS 9.2. I had the RAM upgraded and (separately) bought a 20 GB Travelstar HD so it could handle OS X. So far, so good. The PowerBook did not come with any gray OS 9.2 disks, so once the old HD is out, the old OS can't be reinstalled unless I try to buy some old G3 disks from somebody. Question: Is it really necessary to reinstall OS 9.2 on the Travelstar to get things running or, since I will have a new "retail" OS 10.4 Tiger upgrade kit on hand, can I simply run the Tiger installation disk or disks directly onto the newly installed HD? There is nothing on the currently installed HD that I particularly want to save as all my "stuff" is on the Mac Mini. An Apple upgrade chart I ran across indicated that a Pismo G3 with firewire needs no firmware upgrade to run OS X, so that should not be an issue. Sounds too easy. Am I missing something?
