Yes, you *can* boot Linux from a floppy on an OldWorld PowerPC without
needing MacOS.
I have Debian 3.0 installed on a PPC 9500 and the steps to create a boot
floppy are outlined in the Debian install guide for PowerPC.
You can get the floppy disk image from here:
http://ftp.us.debian.org/debian/dists/stable/main/disks-powerpc/current/powermac/images-1.44/boot-floppy-hfs.img
You can use their provided perl script to edit the kernel arguments in
that image.
Instructions and a link to the script are here:
http://www.debian.org/releases/stable/powerpc/ch-init-config.en.html#s8.1
For instance, to boot into /dev/sda5 (my linux root partition), you'd do
perl patch-floppy-image.pl 'root=/dev/sda5' boot-floppy-hfs.img >
boot-floppy-hfs-sda5.img
Then you'd write that image onto a Mac-formatted floppy. I use NTrawrite
which is available on sourceforge, but there are plenty of other ways.
Now you'll boot straight into Linux. Their installer uses it, so you can
wipe out all your MacOS partitions during the install and have a pure
Linux system (which is what I did).
Now, unfortunately Debian is pretty user-unfriendly. Does anyone know
how I could boot the YellowDog installer from the floppy image? Do you
need a second disk (ramdisk image), like the Debian install does? Or can
you do it simply by changing the kernel arguments, e.g. 'root=/dev/scd0'?
