How TO BOOT POWERBOOK FROM EXTERNAL DRIVE?

[fourthtunz]

I have a powerbook 12' 867 mghz, I know I would rather have a new one, but not ready to give up on this old gal yet! Anywhoo I thought the logic board was fried but after letting the powerbook "rest" I came back months later and sometimes it will boot but as soon as I try to do anything it freezes, so maybe the harddrive is fried? How do you get it to ignore the internal drive so it will boot from an external? I guess I could just pull out the internal one?
ideas? Thanks!

Only Intel machines can boot off USB, so you need to use Firewire.

You need to boot off of a Firewire drive, formatted in HFS+, with the partition map set to "Apple Partition Map" vs. "GUID" which is for Intel Macs only.

An old iPod is pretty handy for this sort of a thing....

Thanks Mechozmo that's helpful. I've been trying to boot my Powerbook from a USB drive and now thanks to you I'm going to use a Firewire drive.

How do I format my firewire drive so that it's bootable? I have the OS 10.5 install disk. I want to be able to boot from the external drive, then use that drive to reinstall OS 10.5 on the Powerbook hard drive.

For my external drive I can use a firewire drive or my new Macbook Pro laptop connected with firewire.

Thanks!!

Not to be silly or anything but why can't you boot from your onboard optical?

It should still work with a fried HDD.

Hold down the C key and insert disk when restarting.

Maybe I missed something?

My guess is you're seeing evidence of someone new to the forums actually using the search function

Necro posts are the inherent danger of encouraging searches for problems that have been previously discussed, but not locking threads after a period of inactivity.
