Using BootX I have tried to boot off the 2004.2 LiveCDs. I am able to boot off the 1.4 LiveCD fine with the following kernel options and the RAM disk configured to a size of 32000:
Code:

rw init=/linuxrc cdroot


However, those settings do not work with the files from the 2004.2 CD. I either Tux and a black screen or I run into problems when I try to mount /. I have also tried various permutations of kernel options I found in the forum.

Is this perhaps because there is no G3 kernel on the 2004.2 LiveCDs? Does the G4 one (the one I have been trying to use) even work?

Could it be something completely different?

hi

i just tried it on a g3 beige (rev.a) and u also have to copy the "initrd-2.6.7-gentoo...." image to the mac partition .
then use it in bootx under "use specific ramdisk"

for me it loads the kernel , found the ramdisk ....
but sadly didnt catch the cdrom(controller driver) in the earlyer kernel
process.

so iam stuck here

i ended up in the "busybox" shell

i dunno if the kernel isnt setup correctly for some ide controllers or cdroms ?

maybe someone has an helping hand cause iam absolutely new to ppc and gentoo :wink:

have had pretty much the same trouble, however, I seem to have got a lot further than what most people have indicated here. I used the following options in bootx

Code:
rw root=/dev/ram0 init=/linuxrc initrd-size=32000


turn OFF the video option! you can then see whats happening!

the above gets me through to finding and unpacking the file system on the CD (the squashfs?) thats when the system says "unknown file system" I suspect that the ram disk is too small, because it's similar to the same probs I had when starting out with gentoo 1.2. any ideas what to set it to?

(a lot of posts add "cdroot" to the above code, I found I actually got more response without it)

I eventually got 2004.2 installed by using the kernel and initrd image from my 1.2 release under bootx. once I got it to the stage where I could boot into it stand alone, I compiled the 2.6 kernel, copied it to the mac and I was away. hope this gives people some ideas.

Also having a similar problem with an old world machine.
It sounds like the solution is to use kernel from older live cd in conjunction with the new live cd's through bootx. Okay, great. Where do I get that? The gentoo mirrors only seem to have live cd's as far back as 2004.0.

On a side note, it is kind of disconcerting that an old world compatable kernel isn't on the cd, yet it includes a G5 kernel. My guess would that most people who actually run linux on ppc are using legacy machines that can't run osx, or can't run it fast.

the older live cds are in the releases/historical/ppc directories on your favourite mirror. It's possible that not all the mirrors have this section, though, so look around. 1.4 worked fine on my kanga.

Any chance we can get a sticky with some of this stuff, and a link to enrique's page, as I'm getting tired of saying it, and someone asks at least once a week?

AFAIK (I am new to PPC too) a G4 kernel runs fine on PPC (eg. 604e) and G3 machines. However I can say that the following did not work for me:
- using a kernel and initial ramdisk which does not belong to the LiveCD in the machine's CD drive
- using the 'normal' G4 kernel. I used the G4-SMP one (on a single PPC 604e system (!))

one additional note: In BootX use the options dialog to specify the initial ramdisk (initrd...). This allows to set its size in the main window. Set this size to at least 32000 (30000 what the Gentoo handbook says). From what I know the 'cdroot' parameter is really important. It would be VERY helpful if the Gentoo/PPC handbook would explain what each of them does ....

The 'root=/dev/ram0' parameter is useful (or was at least useful for me) when the system had already a partition named 'root' (see mac-fdisk in the handbook). This prevented the kernel from trying to mount it.

I made my experiences with the 2004.1 LiveCD. Maybe someone should mention that the version of the LiveCD is not important because your system gets updated afterwards. Or in other words: There is no real difference between a Gentoo system installed with 1.x and any other version if both did regularly 'emerge -u world' and such.

I had to go with 1.2 livecd, couse the bootstraping didn't work with 2004.1 and when I tryed 1.4 my keyboard wasn't working, but I managed to install with 1.2 and then slowly upgrade to newer versions.
