If your system supports booting from a CD-ROM, you don’t need any
floppies. Put the CD-ROM into the drive, turn your computer off, and
then turn it back on. You should see a Welcome screen with a boot
prompt at the bottom. Now you can skip down to section 2.5.
If your computer didn’t “see” the Debian CD-ROM, the easiest option
is to make two floppies for booting (described in section 2.4.2) and
then use them to start Debian. Don’t worry; after Debian is finished
with those two floppies, it will find your CD-ROM with no trouble.
