If you are making a new installation of Debian, you should read the installation manual, which is available on the Official CD at:
/dists/potato/main/disks-sparc/current/install.txt (or .html)
Or on the Internet at:
http://www.debian.org/releases/2.2/sparc/install
The Debian installation system, which is called the boot-floppies
(even though it is for more than just floppies), has been further streamlined
and upgraded for users' convenience.
