How to boot Power Macintosh (Performa) 6200 from a floppy?
Just found in my parent's house old Power Macintosh 6200/75, 16 MB of Ram, no CD, some custom Ethernet card (something like Dyna), apple 500 MB hdd.
It runs Mac OS 7.5.1 and has At Ease for Workgroups 3.0.1 installed with everything locked except KidPix and Claris Works.
I want to get rid of At Ease, but administartor password is gone.
Recently I found an article in internet with advice to boot from floppy.
I've created a boot floppy from System 7.5 Network Access image with DD command in Terminal, but when I try to boot it says that "This startup disk will not work on this Macintosh model. Use the latest installer to update this disk for this model." Then I found, that there is a special boot floppy for At Ease 3, but with it I still get the same message. Floppy drive is OK and reads and writes disk perfectly.
Is there any way to boot that crap? (It reminds me about my childhood when I used it).
