As Byrd corrected my statement, any Apple ROM CD will boot a Mac with from a CD with a bootable system on it, like my Hard Disk Toolkit and DiskWarrior CDs as well as OS Installer CDs.

With an external Apple CD it's no problem, with a n internal CD from another Mac in a second source CD Case it's no problem. Minimum config would be an external power supply of any sort and a cobbled together adapter cable.
