FDD can be removed and swapped with CD-ROM drive or 2nd battery. When CD-ROM drive or 2nd battery is installed, you may still use FDD by connecting it via the rear DB-25 port.

LS-120 Drive (optional)

LS-120 drive plugs to the same connector of FDD/CD-ROM drive. It cannot attach to the rear Printer/FDD connector. LS-120 interface is via IDE so there is no connector for external connection. It must be installed in the FDD/CD- ROM/2nd Battery compartment only.

No device driver needed under Window 98/2000/ME. Driver loading is necessary when working under non-Windows OS.

To boot up from LS-120 drive you should set boot sequence as “LS-120, C” in “Advanced BIOS Feature”.

For first time use, the computer will recognize LS-120 as a conventional 1.44MB FDD and boot up normally. Then you may install Windows or load driver for DOS depending on your needs.

The diskette for LS120 is either 1.44MB or Super Disk 120MB.

Diskette eject is controlled by electric motor mechanism. Insert/Remove diskette when the power is ON.

Printer Cable

For most printers there is no special requirement in connection. However, some printer cable does not contain all 25 wires. To avoid malfunction, the printer adapter cable comes with your computer should be attached to the printer cable. The purpose is to re-connect all the ground pins. Devices equivalent to printer such as scanner, Laplink cable, etc. also need this cable.
