10.4 Upgrade not working.

Trying to get 10.4 installed on my 800MHz G4 iMac (running 10.3.9) from a disk marked:

Mac OS X Tiger includes Xcode 2 CPU Drop In DVD Version 10.4 2Z691-5341-A

When beginning the install while still at the white screen with grey Apple logo I get this panic:

panic (cpu 0 caller 0x002DE020) Unable to find driver for this platform: "Power Mac 4,2"

??????

Disk Wizard says my hard drive is OK.

iMac flat panel, Mac OS X (10.3.x)
