You need the Ultimate Boot CD if you want to:
Run
floppy-based diagnostic tools from CDROM drives. More and more PCs are
shipped without floppy drives these days, and it is such a royal pain
when you need to run diagnostic tools on them.
Free yourself from the slow loading speed of the floppy
drive. Even if you do have a floppy drive, it is still much much faster
to run your diagnostic tools from the CDROM drive, rather than wait for
the tool to load from the floppy drive.
Consolidate as many
diagnostic tools as possible into one bootable CD. Wouldn't you like to
avoid digging into the dusty box to look for the right floppy disk, but
simply run them all from a single CD? Then the Ultimate Boot CD is for
you!
This will create an ISO image which you can use to create a bootable CD with your favorite CD burning software.
