I can not get my Power Mac G5 to boot from an external Firewire hard drive.  The external hard drive shows up as a Boot Drive - but when I select it as the Start Up drive - my G5 simply will not use it. Boots from the original internal hard dark drive each time...

 

 

I am pretty certain that the Firewire Hard drive is set up correctly {

 

 

I read somewhere - that some older PPC G5's running 10.4.11 can  not boot from an external Firewire Drive. I can't find any specific information about that however.

    Hi Carl, I think it can boot from FW drives upto 2.2 GB, but hopefully this is an OWC Mercury Elite Pro, which likely has a tiny red switch inside you need to flip for PPC Mac booting, I had to reclone/reinstall after flipping the switch, if it is you might call or chat with OWC to get approval so warranty isn't voided.

    It does show up in the "Startup Disk" control panel - as Bootable. But on Startup the computer just doesn't seem to be able to find it - so moves on to use the internal drive.

    Same exact symptom on mine until I flipped the red switch & recloned. Sad to hear no more red switch.

     

    In System Profiler>Hardware>Firewire, what does yours report for Firmware version & such, like mine above.

    Could be the Red Switch is only on drives greater than 1TB?

    Could be, my 1 TB Mercury Elites are old, before the new Advanced Format Drives with 4096 Byte Sectors, so I don't think they needed it.

     

    Looks like you have a later Firmware revision than mine.

     

    I suspect OWC will get it figured out & working, they sem good about that.
