Late Powerbooks only boot from OSX 10.4.6

And to boot from a USB stick you should press ''command+option+O+F'' at startup (before the chime).

Then check which is the boot drive with ''printenv boot-device''

Then type ''setenv boot-device ud:0,\\:tbxi'' where '0' is the number of the USB drive (check it on Utility Disk - command+i)

Finaly check if it changed with ''printenv boot-device'' again

Then type ''mac-boot'' and it should boot from the USB.

But remember, only Tiger 10.4.6 will boot, none other (believe me, I tried...)

Also, consider replacing the HDD for a 7200rpm HDD or even a SSD - it will completely change your Powerbook!!

Good luck!!
