Re: Booting from USB
How do you get the 10.4.11 onto the flash drive?

Repartition the flash drive with the correct partitioning scheme for your Mac, for PPC Macs this is Apple Partition Map, this will format it as HFS+ as part of the repartitioning. Then using Drive Utility, select restore, using the flash drive as the destination and whatever bootable volume that'll fit as the source. This is most often done with Installer or utility booting disks like DiskWarrior. -- Bruce Johnson Wherever you go, there you are B.
