G5 Cannot Boot From CD

[MacKenzie999]

Hi folks

Trying to boot from Techtool to create an eDisk, my new Dual 2/G5 10.3.5 will not boot from a cd that I have tested on other macs. At the grey Apple screen, the Apple shifts over and down a row of pixels and leaves a few artifacts on my cinema display.Then it just hangs here.

Any suggestions?

Thanks

Is this the first G5 you've tried it on?

Yes... Ours do exactly the same as well from the black-boxed Panther disks... which are 10.3.0

(Edit to clarify: Ours are dual 2.5s)

I have yet to try our G5 installation disks (10.3.4) ... because somebody has 'tidied' them away.

My guess is that the machines need at least 10.3.4 to boot in...

Is it version 4.0.3? If so I think you can just run it in OS X. If its version 3.0.9, you can run it if you have OS 9.1 up to 9.2.2 installed

It's 4.0.2, and the app runs fine on my mac but cannot do certain repairs unless it is the startup disc, which is also required for installing an edisk.

And for an earlier question, yes this is the 1st G5 I've tried it on.

Thanks

When the Cd is in the tray try holding down Option key for a list of boot devices. This was in another thread.

Thanks, but I tried that. Same problem: grey screen, Apple logo shift, artifacts, hang up.

What disks came with the G5? Did you get AppleCare? If so, I'd expect that either the disk in that box or one of the disks in the G5's box would allow you to boot from the drive. However, I suspect that the TechTools disk you have is simply too old to work with the G5, although I'd guess that any disk that worked with any G5 (PowerMac) would work.

I think I got it, put in the TechTools CD, and then go to System Preferences and choose Startup Disk, and select that as the startup medium and restart.

Your not going to be able to boot a 2.5 from anything less then probably 10.3.4 due to the water cooling system. There's some must need updates that were made in the OS and the boot rom probably needs them prior to the OS loading.
