El Torito extension: From http://www.mscience.com/faq27.html:

The El Torito extension is based upon a boot record volume descriptor in sector 17 that points to a boot catalog containing entries enabling systems with the proper BIOS to boot directly from the disc. The BIOS utilizes the INT 19 function to recognize the CD-ROM device, loads a command interpreter and device driver, and then emulates a floppy or hard disk.

I think there are alternate standards which allow booting from a CD-Rom.
