4.5.2. Installing Internal CD-ROM for OPEN 150
Aside from connecting to an external CD-ROM, the OPEN
150 can also accommodate an internal slim type CD-ROM,
depending on the system requirement. The CD-ROM
drive used in the OPEN 150 II is not the common 5.25”
CD-ROM drive seen in computer stores. Rather, it is a
slim type CD-ROM widely used in notebook computers.
To install a compact CD-ROM to the OPEN 150 system,
refer to the following figure and follow the steps below:
1. Detach and remove the rear cover.
2. There is an FDD/CD-ROM bracket holding the CD-
ROM.
3. Remove the bracket from the system compartment.
4. Fix the slim type CD-ROM drive to the small CD-ROM
metal bracket with 2 screws. Please note that the 2
screws need to be incased with 2 plastic washers.
5. Insert the CD-ROM module to FDD/CD-ROM bracket
and fix them with 4 screws.
6. Fix the whole unit to the system compartment
7. Use a 50 pin CD-ROM cable to connect the CD-ROM
to the 50 pin IDE connector on the FDD/CD-ROM
board.
8. Make sure the 4 pin audio cable and 5V power cable is
properly connected from the PC 660A2 to all the
connectors on the FDD/IDE board (Also refer to the
figure on Sec. 4.2.2).
