PowerBook 12", 1.33ghz, 768 ram, etc.

[Aaron Reimann]

So, I have a PowerBook 12", 1.33ghz, 768 ram, etc.

I have had Ubuntu on my Mac, but would much rather use FC.  I
downloaded the FC4/DVD, burned in on a PC using Roxio, rebooted and
the PowerBook would not boot off of the dvd.

So I downloaded the boot.iso, burned it on my mac, rebooted and the
PowerBook would not boot off of the CD.

Do I have a corrupt DVD (2.8gig DVD) AND a bum boot.iso CD?

please help

thanks,
aaron
