Unable to access the CD-ROM drive or floppy disk from the EFI shell

SYMPTOMS

After an Itanium (IA64)-based PC boot into the EFI shell, you are not able to see the CD-ROM device or the floppy device by using the map command.

CAUSE

This happens because the drive was not installed. To access these devices from EFI shell, you must insert media into CD-ROM drive or floppy prior to run PC.

STATUS

This behavior is intentionally.
