I tried it with all vmlinuz-prep.initrd but it hasn't worked so far. I'm sure it has no MCA Subsystem but a PCI. I have also heard that the original AIX Version 4.3.3 won't work with the Bull even it is a RS/6000 clone. It won't boot from the AIX CD's. Maybe this is a hint that there are some differences between these systems. I have also tried the powerpc Mac port because of the openfirmware of this machine.
I also tried the netbooting option from the openfirmware but without a result. I had a problem with the networkinterface of Bull.
