CD-ROM Drives

To use an internal CD-ROM drive with the integrated
audio controller, do the following:
1. Install the CD-ROM drive in your computer.
For instructions on installing a CD-ROM drive that
uses the computer's enhanced integrated drive elec-
tronics (EIDE) interface, see "Installing a Drive in a
5.25-Inch Drive Bay" in Chapter 9.
For instructions on installing a small computer sys-
tem interface (SCSI) CD-ROM drive, see "Installing
SCSI Devices" in Chapter 9.
2. Connect the audio cable from the CD-ROM drive
to the CD-ROM drive audio interface connector
(labeled "CD-IN") on the system board.
See Figure 8-1 for the location of the CD-IN connec-
tor on the system board.
NOTES: The integrated audio controller allows you to
manipulate musical instrument digital interface (MIDI)
files on your computer and to hear output from those files
on external speakers. However, to communicate with an
external MIDI device, such as a synthesizer or other
musical instrument, you must install a MIDI-compatible
expansion card. (For instructions, see "Installing an
Expansion Card" in Chapter 8.) If you use a MIDI card,
set the Sound category in the System Setup program to
Off. (See Chapter 3, "Using the System Setup Program,"
for information on changing System Setup categories.)
To use a joystick, install a joystick-compatible expansion
card in your computer. (For instructions, see "Installing
an Expansion Card" in Chapter 8.) If you use a joystick
card with sound capabilities, set the Sound category in
the System Setup program to Off. (See Chapter 3, "Using
the System Setup Program," for information on changing
System Setup categories.)
