One more quick question that applies to this thread. I have no problem burning DVD's or CD's on the NEC 3500A DVD-RW drive, but so far I can't burn or find a disk that I can prove one way or the other that this drive is capable of booting the machine. I downloaded a copy of Ubuntu PPC Live DVD and it burned fine, but it won't boot. I can hold down the 'C' key all day, no luck. I do not have a copy of Mac OS on CD or DVD yet as this was an EBay purchase last week. One tip I found described a problem with this particular drive and DVD+R media. I tried DVD-R media and no go. I found at least one post on xlr8yourmac that the guy was able to boot with a Tiger DVD using this drive on a G4, so at least I know it is capable of it. I am honestly stumped. Any ideas? I'd hate to go out and buy a copy of OSX only to find I can't boot into it.
What did you use to burn it? I know that Toast is not able to burn bootable DVDs/CDs, at least, I never managed to make a bootable DVD/CD with Toast.
I suppose that you downloaded the ISO-image of Ubuntu's DVD. So, what you can do is open Disk Utility (in Applications/Utilities) and drag the image into the lefthand box (where your HDs are listed). Select the image in Disk Utility, put in your DVD (preferably -R) in the burner, and click on burn.
That's it. If the image is bootable, your DVD will be too. I did that to make a backup copy of my Software Restore DVD, and also with the Ubuntu Live CD ISO-image, and it boots fine (with C-key pressed at startup).
