Everyone keeps telling me, but my retail Tiger DVD is definitely PPC only. I even tried booting it, and no dice. My Leopard DVD boots, and is good for PPC or intel, but of course it is an upgrade disc and requires tiger installed.
Here's the deal. Don't forget that Tiger was released April, 2005...and the first Intel Mac (an iMac) was released January, 2006 (9 months after the release of Tiger, OS 10.4).
The first model introduction of every Intel Macintosh (iMac, Mac-Mini, MacBook, MacBook Pro, and Mac Pro) all ran a version of Tiger. The earliest version of Tiger to run on an Intel Mac was OS 10.4.4.
So if your Tiger disk version is older than OS 10.4.4...then that would probably qualify it as "PPC Only".
If you're trying to install Tiger on a 13" C2D MacBook...the OLDEST C2D MacBook (from 2006) requires (at a minimum) OS 10.4.8. Possibly a newer OS version if the C2D MacBook is a newer model. The NEWEST (and last) MacBook model from 2010 requires at least OS 10.6.3 (no way Tiger would install on this C2D MacBook...and probably a lot of older MacBooks as well).
So there are possibly MULTIPLE reasons why this Tiger install disk may not install on your C2D MacBook.

p.s. The photo above is of a Leopard disk...what does your Tiger disk look like?
