One thing I noticed and find very strange: when I zap the PRAM (alt-cmd P R) I almost immediatly get the white screen with the arrow and then the Mac searches for a bootable disk (Linux boot-floppy or MacOS-disk). >From the moment I make a change in the PRAM (ie the boot-device ata/[EMAIL PROTECTED]:0 and boot-file Linux to boot the Linux-disk), either with nvsetenv or bootvars, and reboot : I get a garbled screen : I even don't get the initial white screen : it's garbled too. I would suspect a hardware problem but then why don't I get the garbled screen with the Debian boot floppy? I'm puzzled.
