If you are replacing the 1.44-MB diskette drive with an LS-120 drive, the system board-end of
the flat ribbon cable should be attached to the secondary IDE connector.

upper position and is restricted in use to a Slimline CD-ROM drive.
The Deskpro 4000N computer has only a single 3.5-inch third height drive bay that houses the
