MultiBootCD (MBCD)
"MBCD is a shell script to make a customised CD-ROM that can boot any kind and number of image files.
Currently 4 types of images are supported:
* Floppy images (1.2M, 1.44M or 2.88M)
* Knoppix-like image (one per CD)
* Kernel-binary images (e.g. memtest86)
* Windows XP Recovery Console
Note that using more than one Knoppix image is currently not possible, but may be in a future version. And of course you can't use the original 700MB Knoppix version (unless you use 800MB CDR blanks). See below for some smaller alternatives.
MBCD is licensed under the GNU GPL (http://www.gnu.org/copyleft/gpl.html)."
