Hi I just ordered my 5th power supply for my powerbook g4 and i think they finally got it right. I installed using the Live ppc CD and after i enter: boot: live or boot: live-powerpc or even boot: live-video=ofonly it begins to load some things... And then I get a message stating:
[2.179521] 0000:00:10.0 Raedonfb Invalid ROM contents At which point the screen then displays flickering bands and I cannot continue. Thoughts?

Try installing debian first and installing ubuntu over it. I was experimenting different ppc friendly linux and ubuntu only worked after I installed it after debian I'm not sure why but I think it has to do with the way macs boot or something debian adds to the boot process that ubuntu doesn't.

Well i tried this...it seems that after the os loads it displays a foggy or cloudy display. is there a way to get to a prompt to allow me to make changes...all i have at the moment is a boot menu prompt.

Sounds like your ati radeon card is taking a dump. Try booting with a mac os X disk and see if comes up normally. Or, grab an s-video cable and hook up to a tv. I believe the s-video bypasses the ati card and goes direct to an ntsc or pal signal.

Try an external DVI or VGA monitor. It may work whereas the internal video is showing its age.

but i'm able to watch the boot process. Wouldn't a blown video card even keep that from occurring?

No because the Radeon card has different channels to process video. It's possible that the high-resolution graphics portion of the chip is blown. The chips get hot and lift off of the surface of the motherboard. Nearly impossible to fix. It's a common problem on older machines. It's also possible that the video RAM is wonky. Text-mode graphics don't need much RAM but the high-res graphics do.

Only by booting into OS X will you really be able to tell if your graphics are working 100%. The linux drivers are reverse engineered and may not work 100%. There are some diagnostic modes that you can boot into, but I believe you need the Mac disk and a special key combination, which I don't remember.

Hi !
I just tried PPC live cd and have the same symptoms.
Finally I booted into live-nosplash (or whatever it called) and got ubuntu desktop.
It is not a hardware issue, because I successfully boot into OS X and keep working.
I think, the right way is to change kernel parameter - put something like "no splash" here.
Hope, this will help!
