installing on PPC Mac Mini without any OS installed (sent to http://www.lists.debian.org/~debian-powerpc)

[http://www.sneakemail.com/~bccme]

I had to have my hard drive disk on my Mac Mini replaced.  It is now blank.

Is there a way to install Debian without any OS installed?  From all I've read, it seems like MacOSX needs to be installed before Debian can be installed.  Is this still true?  I may be able to get my hands on a Mac OS CD, but I'd prefer to get install Debian from scratch.

Thanks!
