arch install on Imac G5-SOLVED

Trying to install Arch on a G5-Imac.CD boots normally but when trying to start the installer it gives an "Invalid memory access at SRR0 and SRR1 (with big numbers)"

Any idea what is going on here?

ARCHPPC finally running on 64-bit with 32-bit userland

Re: arch install on Imac G5-SOLVED

Are you using ArchPPC or standard Arch?

Re: arch install on Imac G5-SOLVED

When exactly does this happen, when you run /arch/setup or when kernel boots?  In theory archppc could run on a G5, since it supports  the same 32-bit subset of instructions  that are used in G3/G4 processors.

Re: arch install on Imac G5-SOLVED

Just after starting.It does not even reach setup.I did also try with Debian (keyboard problems) and Gentoo (nothing to see on the screen).Mac OSX runs perfectly,so the HW seems OK.

Please be more specific. Do you get a yaboot prompt? Does the kernel start loading? Or do you start the computer, press the key-combo for cd-boot and it hangs?

Re: arch install on Imac G5-SOLVED

It gets the yaboot prompt,as far as I can see the kernel boots (on a white characters on black screen) then the colors invert with following messages:

found display etc; etc ...done

building dt sttructure ...
Device tree strings 0x02fcc000 -> 0x02fcd4e0

END OF THE MESSAGE AS SEEN ONSCREEN

At this prompt it is impossible to give any command.

Hope this can help you.
So long.

Re: arch install on Imac G5-SOLVED

To add to the story:I installed kubuntu,it works but veryyyy slooowwlyyy,completely unuseable.

Latest opensuse for ppc (network install), works perfectly but I do not like Suse,I want Archppc.

Also retried Archppc with all kinds of variants but to no avail.Some people must have installed Arch on an Imac-G5,it should work,just "HOW?"The machine can do Linux perfectly as the Suse install proves so what is wrong with Archppc or the installation wiki?

Re: arch install on Imac G5-SOLVED

You could try to reset nvram+pram: power on the machine and press command+option+o+f  to get an OF- prompt and enter:

reset-nvram
reset-all

Pressing cmd+opt+p+r during power on and wait until it reboots should also work.

If this doesn't help, then you might need a 64 bit kernel.

Re: arch install on Imac G5-SOLVED

The reset gymnastics did not work, so it will be as you suggested (and as I already suspected) so it will be a 64-bit problem.The installs that succeed fully or to some degree are all 64-bit versions and that made me somehow suspicious.

Has someone already done an install on PPC/64 Imac and can share his experience?

So long

Re: arch install on Imac G5-SOLVED

This may work, maybe someone else could expand/modify/crush it.  Since the SuSE install works, maybe you could get it going by:

-install SuSE
-set up arch in a chroot environment; recompiling the arch kernel could give some reassurance.
-wreck the SuSE install with the arch one (overwrite / with /path/to/chroot/ )
-make sure yaboot is set to the arch kernel

Either way, this could be answered a lot quicker if someone with a G5 system were to chime in on the subject.

My roomates said they were going to get me rims for Christmas, or a CB radio so I can talk to other car beds; that'll be hot. Might get a stereo, too.  My sister said I should get an alarm.

Re: arch install on Imac G5-SOLVED

maybe you'll receive more help on ppclinux.info. There are some other iMac/ArchPPC users.
btw, does cruxppc succesfully boot on your imac g5?

Re: arch install on Imac G5-SOLVED

Consider this thread closed as we have 64-bit archlinuxppc now.
