Hard drive has DDO

If you have installed your hard drive using a DDO (Disk Drive Overlay), the computer may not see the hard drive using a bootable diskette.

To determine if you are using a DDO and to utilize that DDO with a bootable diskette, reboot the computer without any bootable diskette or CD in the computer. As the computer is booting, you should receive a message "Press *key sequence* to boot from a bootable diskette." The *key sequence* can vary depending upon the DDO installed on the computer. An example of such a key sequence is Ctrl+Esc. If you do not see this message when your computer is booting, it is likely that a DDO is not installed on the computer.
