I'm currently trying to install gentoo on an old IBM 43P-150 workstation using the install-ppc-universal-2005.1 CD.

Booting directly from the cd does not work.

I tried starting yaboot directly from the OpenFirmware-Prompt with boot cdrom:\boot\yaboot, that did not work either.
Same with trying to start the kernel-file (ppc32) directly. All I got was the message "unrecognized Client Program formatstate not valid".

I tried setting the load-base to 0x1000000 and even reduced the installed memory to 512 MB down from 1 GB.

The firmware has been update to the latest available (TCP05287).

Is there any way I could possibly install gentoo or any other linux-distribution on this machine ?

Update:

When I set the load-base to 100000 I was able to start yaboot, but it did not find neither its config-file nor any of the kernel-lfiles specified directly on the command-prompt (yaboots prompt that is).
Trying to boot the ppc32-kernelimage yields:

Unexpected Firmware Error:
DEFAULT CATCH!, code=fff00300 at %SRR0: 00c1b030 %SRR1: 00003030

and returns to the OF-Prompt.

Well, I don't know what kind of hard disc controller that machine has, but if its IDE or SCSI, why not unplug it and stick it in an x86 or ppc box, with linux already installed (or using a knoppix-like liveCD as the host install environment)

Then you can just fdisk, format, mount, untar the tarballs and chroot to do the install, provided you know what architecture tarball is the one to use for IBM 43P-150.

Once your done, move the HD back across to the 43P and see where it fails. (Cos unless your a genuine genius we both know at least the first 3 attempts to boot something like that are destined to fail!!!)

Good luck

It's a SCSI-Harddrive, and as I do not have a compatible hd-controller (at least afaik, i have some really old scsi-controllers lying around, but these probably wont do), that is not an option. Even if I could connect the disc, I dont have another ppc machine around, so chroot wont work.

If seen a few people in this forum claim to have linux running on a IBM RS/6000 43P-150, so there should be a way to install it without resorting to harddrive-swapping.

Could anyone who has gentoo running on a 43P-150 give my some pointers please ?

Have you seen this one? Debian 3.0 Woody installed on my IBM RS/6000 Mod. 7024-E30:

According to one post I saw on a debian list, the user found the zImage could only be booted using bootp server:

I was finally able to boot into the rocklinux installer.

Using drock-2.0.1-rev3163-ppc_cd1.iso and directly starting the file yaboot.rs6k I was able to start into the second stage installer which in turn enabled me to download a stage3-tbz2, from which i am currently installing the system (compiling takes a looong time on this machine).

I now have a working gentoo 2005.1 running on my IBM RS/6000 43P-150. :D

Here is what i did:

1. I booted from an older Rocklinux-ppc-iso (drock-2.0.1-rev3163-ppc_cd1.iso), using:
Code:
boot cdrom:\boot\yaboot.rs6k


2. When Rocklinux had started, I essentially did a normal gentoo stage 3 install.

3. Kernel-config was pretty straightforward, the kernel i built has support for pcnet32 and scsi builtin, the config-file is available on request.
I used the kernelimage named zImage.chrp-rs6k.

4. yaboot: Installing and setting up yaboot was quite an adventure but what finally worked was:

First I created a bootstrap-partition, type 0x41. Then I emerged yaboot with "ibm" in USE.
I used following yaboot.conf-file:
Code:

boot=/dev/sda1  # The bootstrap-partition
device=disk:      # Important! the default hd: did not work for me
nonvram

partition=2        # Number of the partition where the kernel resides, in this case /dev/sda2. (Only ext2 worked for me)

delay=10

timeout=40
install=/usr/lib/yaboot/yaboot

image=/kernel # Kernel-Image relative to the boot-partition
        label=Linux
        root=/dev/sda4
        read-only


Afterwards I set yaboot up using:
Code:

mkofboot --filesystem raw -b /dev/sda1
ybin --filesystem -b /dev/sda1


Afterwards the OpenFirmware started yaboot directly from the harddisk.

I am currently emerge xorg-x11 and will update this post when I know how to setup it up on this machine.

You're my hero :-) I have exactly the same machine at home, I think I'll give it a try using that RockLinux CD you mentioned!
