SUSE9.1 install problem

Hello guys I have experienced a problem during SUSE9.1 install. I have a PIII 833, 256+128MB RAM, grafic card card i815. The problem is that I put in the first CD into the drive, it starts and I choose install from the menu. It starts to load the kernel, after the kernel has been loaded(not started) the machine reboots. I have tried to choose another menu entry: manual install, safe install the problem remains the same. A have also tried to disable the splash screen (splash=0, acpi=off, idedma=off) no use. I have also tried to remove the 128MB RAM no change, I have removed the 256MB RAM no change. Any help would be appreciated. Thanks Zsolt
