cant boot linux on imac g5

Hey everyone, I recently got myself an apple imac g5, and decided to try to install debian sarge on it. I've been playing around with livecds and that sorta thing for a while, and have tried to get them to boot by holding down the "c" key. I've gotten yaboot to load in all of them, but after that the machine would freeze up. I just attempted to boot debian sarge netinstall disk, and I used the "install-power4" option in yaboot, which i read would correspond to a g5 chip at The screen is now locked up, with the following text on it:

Welcome to Linux, Kernel 2.6.8-power4

Linked at :0xc0000000
frame biffer at :0x98008000 (phys, 0x90000000 (log)
klimit: :0xc02f6660
MSR :0x00003030
HID0 :0x00000000

pmac_init(): exit
id mach(): done
MMU:hw init

I don't know what any of this means, and the keybaord is completely locked, no key is responding at all. If anyone has any advice as to how to get debian loaded on an imac g5, help would be much appreciated. Thanks.

I am not sure of a solution for you, but I can tell you these messages are created by a "show early boot messages" option in PPC kernels.

Have you tried another PPC livecd on this machine? I have had luck with the kanotix PPC livecd on my G4, but have not tried it on my G5. If it boots then it may mean a bug in the debian cd.

I've actually also tried the gentoo install cd, and ubuntu live/install cds. I've had similar errors with all of them. I think i'm going to attempt to install debian via another method. Does anyone know if it would be possible to do a network boot with a debian x86 machine and this imac g5 on the same network? I wonder if any other debian installation methods don't work, and I already have a working debian machine on my other x86 computer.
