I am going mad, since I have tried to make these Performa boot for may be 2
months now...
My situation is the following: these Performa are for use in a
university, and since I can't make them boot from the harddrive (I tested near
everything possible), I need a boot floppy. But I would like the boot process to
be possible whithout any user intervention. So could you please explain me the
whole process for creating a boot disk like the one Debian use for installation?

What kernel to use exactly: vmlinux.coff? vmlinux.gz? ....
How to make the boot disk? using Miboot?

What I have tried for now is to change the kernel of the Debian bootdisk,
then bless the floppy with hattrib and try to boot on it. But none of my kernels
worked, althought I used the .config from kernel-patch-2.2.19-powerpc and I
correctly patched the kernel sources with the patch.

a good explanation (or a link to an Howto or a FAQ on it) would be greatly
appreciated. I really need to solve this problem...

thanks in advance.
