SuSE Linux on RS/6000

Hello. I installed SuSE 7.0 Linux for PPC on an RS/6000 43p model 150. Before installing SuSE I had AIX 4.3.3 in that box so, I had to format the hard disk with the AIX diagnostics CD, because if you don't do that, you cannot install SuSE. Later I had to install again AIX in that box, but I'm not able. I've tried to format the hard disk, but is useless. Has anyone tried to install SuSE in an RS/6000 and after, tried to install AIX? I'm not even able to restore the backup copy of the operating system done with mksysb (aix smitty) Thanks in advance Regards, Jorge Cambra
