Hello there

to resume my problem

my 2.5" toshiba MK 6022GAX sticked in to an External enclosure powered with AC adapter with an I/O IC from Prolific PL3507 Combo (tested to be booteble )
formated HFS+ journal and tested by techtool 4 to be OK, will not BOOT!! Installed OSX from original MAC OS CD.
MY PB G4 1.33 256 60 GB 15" runs under OS X 3.5.
System Profile see External FireWire HDD an ID it correctly. DiscUtility let my Formated HFS + J. and is works fine ( copy my PB with CCC on to the drive let me use all my app. like it would be my original PB. )
System Pref. "SEEs" the FireWire and the OS and lets me selected it as an start up disk. but after restart screen stays grey.
restart with -option key gives me a blue screen with no selection to choose from ( no icons at all ) .
after disconnecting XHD drive PB boot up fine.

why i can not boot from a external FireWire Drive. ?

kindly
Stevan

Look slike you covered all the bases and as the above poster said, some chipsets are not 'boot friendly.'
