Problem installing on PowerMac 8600

[Patrick Bachmann <patrickbachmann@gmx.net>]

Hi folks,

This OldWorld-maschine doesn't want to boot the floppies, I'm trying to feed 
it with.
There are various floppies I have tried, e.g. the woody and sarge boot 
floppies and the floppies of the rc2 of the debian installer. 
The only floppy, that gives me some kind of feedback is the 
boot-floppy-hfs.img. After being read, an icon of a floppy with tux on it, 
apears. But nothing else happens. 
Can someone please give me a pointer at what to do? I really want to resolve 
this issue, it has been occupiing me for a while.
I found comments of people using similar hardware, who were successful with 
floppy-images that just don't work for my machine.

Cheers,

Patrick
