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!!
