<p>PROBLEM TO BE SOLVED: To optimize the miniaturization of a portable computer, and to prevent the generation of any malfunction. SOLUTION: An inside FDD unit 14 and an inside CDROM drive unit 15 are selectively mounted on an FDD/CDROM slot 13. In this case, when the inside CDROM drive unit is mounted, an outside FDD port for connecting an outside FDD unit 16 is automatically set to an enable state, and the outside FDD unit 16 is made to be usable. Also, when the inside FDD unit 14 is mounted instead of the inside CDROM drive unit, the outside FDD port is automatically made to be disabled.</p> |
