Changing the boot order also changes the logical drive
designations. For example, if you start up from a hard drive in the
MultiBay, it becomes drive C and a hard drive in the primary hard
drive bay becomes drive D. Starting up from a network card does
not affect logical drive designations.
The diskette drive reads and writes information onto a
3.5-inch/8,89-cm diskette.
The MultiBay also accommodates an optional LS-120 drive.
Each drive accepts the following diskettes:
