This is the modular option bay. A second battery pack, floppy
drive, or CD-ROM drive can be installed into this bay. This bay accepts
the modular CD-ROM drive, the modular internal floppy disk drive,
or an optional additional battery pack. The modular option bay
houses either drive or the battery pack, but only one at a time.
To use CD-ROM drive and floppy disk drive functions simultaneously,
install the modular CD-ROM drive and connect an external floppy disk
drive to the floppy/parallel port on the rear of the computer or
the optional docking station, or use the optional external floppy disk
drive adapter for the floppy disk drive module.
