Can powermac g5 boot from USB?

There is something wrong with my HDD, and I don't have a blank CD/DVD

Thats a shame, man! That superdrive is a great little drive for what I use it for and its fast, boots up Tiger and Leopard in no time.. But, alas.. You got the 100.00 OWC external which is nice also.. just bulky. As for the 3TB Barracuda, did you format the drive in Disk Utility as Apple Partition or APM?


Remember, these drives come pre-formatted for PC's, so you need to format it for Mac using PowerPC's APM partition scheme. 2.7TB sounds like the norm as some space is reserved for the operating system, so no problem there. I believe the Apple Partition Map can only accept up to 3TB.. 4TB wouldn't work as you would have to partition it.


devalias also called: device alias - shows what hardware devices are on your logic board.. USB,USB1,USB2, etc.. mean the USB ports.. ud is short for USB DEVICE.. and this is what your would find in order to boot the PowerPC using USB. You also have USB on the OWC External which you ordered.. Try this:


Try to boot from USB when you get it.. Hold down OPT+COMMAND+O+F to get into Open Firmware. Next type "devalias" and search for "ud". Once you find ud with your Leopard or Tiger disk in the drive.. type:


boot ud:,\\:tbxi - This will start to boot from USB.


easy.

Got it!! I'll tell you what I think happened, so others reading this thread might be helped.


Either one of two things probably happened: when I tried to use Carbon Copy Clone and it failed, I "erased" that boot partition in Disk Utility, but when I tried SuperDuper, that didn't work either. SO I just tried to load Leopard on the new disk, as I said I would. Turns out that it would not let me use the partition I made for the Boot Drive for Leopard either. This is surely why Super Duper didn't work. Either the first time I erased CCC corrupted the partition or it was corrupted from the getgo- I wonder if it's because I didn't use partition 1 as the boot drive. That could be it too. Anyway, once I reformatted the whole HD, I loaded Leopard, Migrated the stuff, then used Super Duper to move my media drive to the second partition. All's well and I'm not even getting any panic reports from DP when I shut down. Thanks so much.


Now there's just one more thing I want to know: can I plug in my old optical and have the OWC optical firewire too? When I go to burn something, would it default to one or the other or give me a choice? I'd like to put it back in the computer, as it's convenient.

That shouldn't be a problem.

That will likely depend on the software used. OS X Finder services will most probably default to the internal, but I can't say for sure.



I'm glad to hear that you fianlly got things transferred and stabilized!

I guess you're right. I'll just have to try it out in iTunes v. Toast Titanium, etc. One thing I'm finding is that when I access apps on the new drive, it asks for the installer disk and code. Thankfully, I have everything, but it makes for more work than I thought.


Thanks again, and I hope that someone upgrading Tiger to Leopard on a PCC G5 (without the ability of the stock optical drive to read the Leopard installer disk), while simultaneously consolidating everything to a new partitioned Seagate HD (with a Lynx system!) learns what they need from this thread.
