Linux on RS/6000 E20
Hi all! I want to install Debian GNU/Linux on an IBM RS/6000, model E20. The problem is that I don't have access to technical data about this machine. Oh, and the machine does not have a graphics card :-). Right now I have a serial console working. I have used the "current" PReP boot disks from people.debian.org/~aph/. When switching on the machine, Linux/PPC loads and shows a command line. After pressing enter, the kernel is loaded. But after the message "Okay, now booting the kernel." nothing more seems to happen. Does anyone know what could cause this problem? I can supply a complete boot log if you wish. regards, Benny.

Okay, now I have got some boot messages, but they do not look very good :-( (see attached file). It seems the linux kernel on the boot disk does not cope very well with this machine :-((. regards, Benny Siegert. rs6000-bootlog Description: Binary data

The problem is that it does not load beyond the SCSI initialization. Boot log is attached (again :-( ). regards, Benny Siegert.

Since my last tries with Linux, I have booted the freshly-installed AIX. Unfortunately, I get no login prompt on the serial console, and the machine does not seem to have an IP address set :(. --benny.

Nor do I :-). Seriously, I haven't got a kernel to fully boot yet. At some time during my tests, I installed AIX. When I switch on the RS/6K now, I get AIX boot messages, but no login prompt on the serial console. Oh, and the machine does not have an IP address set either, so I cannot even use telnet. And since then, it has been ignoring the boot floppies I stuffed into the drive, always booting the broken AIX. I am not an RS/6000 expert, and I don't know what to do next :-(. Back when I could boot from floppy, I used a zImage.prep written (with rawrite under Windows) to a disk. Olaf Hering <[EMAIL PROTECTED]> provided me with some advice: > Dont try to run 2.2 on non-IBM PRePs. > Try http://master.penguinppc.org/~olaf/2.4.12/zImage.prep or > ftp://ftp.suse.com/pub/suse/ppc/kernel/2.4.2/zImage-2.4.2.prep Unfortunately, both kernels did not work for me. For my machine, it is crucial that only one of the 53C8XX SCSI drivers be enabled. Later, one developer provided me a cross-compiling environment as a tarball to download. Unfortunately, the download always timed out. I think I will try to get a friend of mine, who is a PowerPC developer, to build a kernel for me. --benny.

A few weeks ago, I set up a cross-compiling environment too. My aim was to compile a Linux/PPC kernel under OpenBSD/i386 (crazy enough, I know :) ). What I did was the following (IIRC): 1. Download binutils sources (I used stock 2.11.2). ./configure --prefix=$HOME/cross --target=ppc-linux ; make ; make install. 2. Download gcc-core-2.95.3.tar.gz (or, at your option, any newer version) from gcc.gnu.org. export PATH=$HOME/cross/bin:$PATH ; ./configure --prefix=$HOME/cross --target=ppc-linux --with-newlib ; make ; make install. 3. In the linux kernel source tree, edit main Makefile: The 'ARCH' line has to read: "ARCH = ppc" (or, in your case, m68k). gmake xconfig (it is necessary under OpenBSD to use gmake -- under Debian GNU/Linux you just use make) ; gmake dep clean zImage. This was simple enough, and it worked fine, though I had expected it not to ;-). --benny.

Don't know about the E30 or the B50, but I have an E20 here. Do you have a model with a graphics card? If not, you have to explicitly tell the kernel to use a serial console. The command line goes like this: root=/dev/fd0 load_ramdisk=1 console=ttyS0,9600 If you want, I have a 2.4.17 kernel with Ramdisk and SCSI support. However, it does not fully boot for me: The scsi driver (no matter which one I choose) hangs at startup :-(. Without scsi, I can start the installer, but its useless without disk access :-(.

Alas, I have lost most of the RS/6000 kernel files in a hard disk crash, so I do not have the config file for this kernel. The driver that fails is the one under CONFIG_SCSI_SYM53C8XX_2. The other 53C8XX drivers available also hang. Has anyone got an idea what could be wrong? Regards, --benny. screenlog.1 Description: Binary data

The machine has got 64 MiB of RAM. But I do need the SCSI drivers, as there is no IDE controller or a similar thing :-(. Ideas, anyone? Regards, Benny.

Oh, so I'm not the only one out there with an E20 :-). You have a
difficult task in front of you, but YMMV.
I assume you have a model with serial console. When you power up the
machine, you should see some lines like this:
dskt. OK
mem.. OK
etc. Before you hear the beep, press the "5" key on the keyboard. You
should see the firmware menu. The topmost two lines contain the
revision number. You should have firmware version VIC97216, dated
03/10/97. If the firmware is older, go to
http://techsupport.services.ibm.com/server/mdownload2/download.html
and download a newer version. Instructions are at
http://techsupport.services.ibm.com/server/mdownload2/7024e20.html .
To boot a kernel, you just have to take a zImage.prep file and dd it
onto a floppy disk (e.g.: dd if=zImage.prep of=/dev/fd0 bs=1k). Then
insert the disk while booting. If this does not work, you might try
the following procedure:
1. Go to the firmware (as above).
2. Select point 1 (Select Boot Device).
3. Select "Other boot device" and then "3,5 Floppy".
4. Select "Boot".
You will see a screen like the following:

At the moment, I have a stock 2.4.17 kernel. It boots, but hangs after
loading the SCSI driver ("SYM53C8XX Version 2 SCSI Support"). It seems
that this driver does not work reliably on PReP machine (someone else
on this list had problems with it on a Motorola PReP box).
Today, I made some experiments with the linuxppc-2_4-devel (bitkeeper)
tree. But the disk would not even boot :-(.
If you want, I can send you one of my kernels for testing. It would be
interesting to see if you have any success.

Benny Siegert.
