Obviously the Book is not seeing the disks that you're trying to boot from. Try using a 10.3 system as you do not have the firewire required by 10.4.
To use Mac OS X v10.4, your Macintosh needs:
A PowerPC G3, G4, or G5 processor
Built-in FireWire
At least 256 MB of RAM
DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools
