Abootable CD-ROM may have either a floppy disk for- mat or a hard drive format. When the bootable CD- ROM is used, the drive allocations change automatically without changing the BIOS setup. If a floppy disk for- mat CD-ROM is used, the CD-ROM becomes Drive A. The CD-ROM will only take Drive C: (hard drive for- mat) if the internal hard drive is not present or is dis- abled. The bootable CD-ROM can never use a C: designation if a formatted internal hard drive is present, since the C: designator is always reserved for the inter- nal hard drive.The boot sequence ignores the new drive designations; however, your application software will use the new designations.

Be careful of the operating environment when booting from a CD-ROM or you may overwrite files by mistake.
