Debian MacOldWorld installation

[Jerome Le Saux]

Hi all,
I imagine you might be bored to see such mail. I'm sorry but I read the Debian Manual but also on the net via google to try to find an answer to my problem.
I used to install Debian distribution on other architecture such Intel, so my question is only on the CDrom boot.
I downloaded miboot floppy to boot.
Miboot returned me : Kernel Panic VFS unable to mount root FS on 08:01.
What's wrong, my harddrive are not supported ?
Must I add specific driver for them ?

My machine :
Machintosh ppc 7600
CDROM
FLOPPY
2 harddrives (2.1 GB and 9 GB scsi, both recognized under Macos 8.5)

Thank you for your help.

Sincerely
Jerome
