Dear Sebastian Schroeer! Your workaround is usable - at least partially. In general it is still possible to have a bootable Debian beside a bootable MacOS 9 at the same disk, as long as the Hard Disk is smaller than 128 GB. The last 3 days I did 8 or 9 complete installations of MacOS 9 AND Debian, so let me report what happened.

I was referring to the "Debian GNU/Linux Installationsanleitung" http://debian.org/releases/stable/powerpc/ch03s05.html.de#id2726490 As I already knew the tip with restarting, after Debian installation, with the MacOS CD and using "update the driver" ("Treiber aktualisieren") from within drive setup ("Laufwerke konfigurieren") from earlier debian list postings (see above: http://lists.debian.org/debian-powerpc/2008/05/msg00047.html ), I began by repartitioning the entire HD, and putting the Linux partitons at the end of the HD like you suggested. Who knows maybe the partitions at the end would have worked, ... but they didn't. I tried manualy partitioning from within the Debian installer, and also automatically partitioning of the "biggest free space". When I did the automatically partitioning at the end of the HD I recognised that Debian installer reports the entire HD as valid - a 250GB Seagate disk - while some G4 computers, like mine, have only controllers for 128GB onboard, what is always reported correctly by MacOSs "drive setup". But I could use, and even start to install at entire 250 GB with Debian installer. So I tried to repartition the drive with "drive setup" by doing 3 partitions. A small one at the end (of the 128 GB), and having 80GB for Debian before that last small one, as I thought maybe debian will only use that 80GB inside the part of the HD which is usable by the controller. After every repartitioning -> installing MacOS 9 -> installing Debian -> I used a MacOS 9.2.2 CD, and as it didn't work, the original MacOS 9.1 CD that belongs to the machine, for trying if I can update the drivers. But it never worked. I followed the idea that the problem is the "too big HD", and tried repartitioning the HD from within MacOS, with all partitions that Debian will need. A small one for yaboot, a big one for "/" and a Swap partition. Doing this, the debian installer should have only changed the filesystems but not changed the partitioning itselve. But also with the disc partitioned by MacOS and not by the Debian installer, I was not able to use or boot my MacOS 9! I was also not able to use the drive setup for updating the driver. That is really strange, as the partition table was not touched by Debian, only the filesystems at some partitions, ... So I finally switched to another 80GB HardDisk, used "drive setup" for creating 2 partitions. One 30 GB HFS+ and one 50 GB "undefined". Rebooted into Debian installer from CD (the one I used at my first try -> see the first report here at #604134) and used atomatically partitioning of the greatest free space, as I did several times before with the other HD. After installing Debian, I changed the yaboot.conf and added macos (like also done many times before), used "ybin" and rebooted with the MacOS 9.2.2 CD. It was immediatly possible to use drive setup, and update the driver. Now I have a working MacOS 9/ Debian dualboot system. Later I tried to veryfy everything, but my old Maxtor 20GB HD seems to be broken. I could not install Debian at all, and I have no further empty HD. So I am not absolutely sure, but belive the following (also because many other people reported to use MacOS 9 successfully beside Debian): -) The bug I reported only occures if the physical size of the disc is bigger than the maximum possible size that the controller, built in to the Mac, can handle. Only early G4s are limited to 128 GB. Later G4s even supported 48-Bit-LBA at the onboard IDE controller. -) There is no dataloss under circumstances that the disk fits to the maxiumum possible size, usable by the built in controller (128GB at early G4s). -) If the disk is bigger than the size the controller can handle, there is recently no way to correctly use it. You would need to do a manually partitioning to the maximum of 128 GB (at early G4s) and you will not be able to use MacOS 9 and Debian at the same disk - means you will loose your MacOS 9 installation and never be possible to restart it again, even when access to the data in general is possible through Debian. -) You need to update the driver in every case from the MacOS CD after Debian installation, to be able to reboot into MacOS 9 (or 8.6) again, but this workaround only works if the disc is smaller than 128 GB (if you use the onboard controller of the early G4s). I would suggest the following: -) write a huge warning into the installation manuals -) trying to fix the problem when using bigger disks at the original built in controllers (but beware, as recent Terrabyte disks are no problems throught PCI cards, and seem to be used often at G4s) -) downgrade the bug if needed, as it only affects early G4 Macs with upgraded HDs bigger than 128 GB which do not use the availaible space over 128 GB. A case that might be rarely, as users normally use addon cards for using bigger SATA or IDE disks. kind regards Mathias Wittau -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
