Please read the advice for 12.10 and 12.04 below. Please confirm the hw-detect bug ( see comments #10 and #14).Ī fix for the PowerBook6,5 using DKMS can be found here and a more generic fix is here. You will need to set that yaboot parameter again after an installation as that will not carry over from the booted ISO - see FAQ for how to do this. Like previous versions, some systems will need the yaboot parameter radeon.agpmode=-1 to circumvent freezes (so far this is confirmed for Radeon 9200 chips in AGP based G4 iBook's). This means KMS is on and active from the go! The legacy radeon framebuffer (radeonfb) is nolonger built-in to the kernel, but is now compiled as a module - see bug. 8.04 PowerPC brightness buttons on iBookG4 12".8.04 PowerPC LiveCd will not boot on iBookG4.Looks like you have 512 MB of 533 MHz PC2-4200 DDR2 SDRAMĮxpandable to 2.5 GB in your iMac G5 according to Wikipedia.See Debian hardware requirements.ĮDIT: Ubuntu has PPC port as well but it's unofficial and is maintained by the community.It's very difficult to find the download links for it.I don't know why.But at least I found a Ubuntu Server 20.04 for POWER architecture but not PowerPC and I don't think you can run it in your iMac. As far as I know ubuntu doesn't support PowerPC architecture in the newer releases anymore(To be precise, from Trusty Tahr or 14.04 onwards).However you can download the older versions like 14.04 but that's not maintained in the ubuntu official download repository anymore.So you have to use the Wayback Machine.įortunately I was able to find a working download link for you that was saved in Aug 2015 (If fact it's Lubuntu which has a lighter desktop environment and is more conservative in memory usage) :īut there is also an alternative : You can use Debian for PowerPC if you want to have a newer kernel and more up-to-date and secure packages in your pocket because the PowerPC architecture is supported officially by the Debian group.īut note that despite of the advantages that a newer OS has, it can be quite difficult to run a new OS smoothly in your iMac because the hardware is rather old.
