[newbie] cdrom bootdisk?

[Mr. Smith]

I would like to know if it is possible (I am pretty sure it is) to create a
bootdisk on a cd.  I would like to know because I am using Mandrake, BeOS
(free), and Winblows.  I find the floppy slightly...slow.  So I was just
wondering how I could create a bootdisk to launch linux from a cd instead of
the floppy I created.

Thanks in advance,
Mr. Smith
