Can Mac OS X or Linux be used on a bootable floppy or CD?
Linux can be booted from a floppy or a CD, although very few modern distros are actually booted or installed from floppies. Mac OS X cannot be booted or installed from a floppy; the last version of the Mac operating system that could be reasonably booted from a floppy was System 6. Mac OS X versions up to 10.4 could be installed with CDs; 10.5 and later require a DVD.
