eMac [ATI Graphics], 1GHz G4, 1GB memory, 160GB hard disk, 32MB Radeon 7500, SuperDrive, Airport Extreme. Works perfectly. Came with Panther, 10.3.2, later I wiped it and upgraded it to Leopard, 10.5.8. Anyway, I now want to use a specific Classic application, so I figured I'd wipe the drive and install Tiger (I've got the 4x CD, PowerPC only version of Tiger.) Those installer CDs have worked fine installing Tiger on my 466MHz Digital Audio G4 tower. Anyway, I can install Leopard from my DVD, I can install Panther from the original eMac restore 10.3.2 DVDs, but not Tiger. It is recognised as an installer disk in the Startup Disk preferences in Panther, and if I have the CD in and boot up holding the option key, it shows up as a startup disc... but if I select it to boot from, or double-click the installer itself from within the Finder in Panther, or simply try to start up from the Tiger CD, it won't work. Grey screen, Apple logo, spinning gear... goes on for about 10 minutes then the computer just shuts off. It boots fine from a DiskWarrior CD, and after a [failed] Tiger installation [see below] I rebuild the directory and did everything I could, but still no success. I've also tried using Pacifist on my G5 Mac to install Tiger over Firewire; I've also tried installing to a disk image on my G5 and then using SuperDuper to clone the drive and make sure it's bootable, but in both cases the eMac just boots to the flashing "?" missing system folder screen.
