2-26 Chapter 2: Hardware information
13. Internal audio connectors (4-pin CD1, AUX1, MODEM1)
(on audio models only)
These connectors allow you to receive stereo audio input from sound
sources such as a CD-ROM, TV tuner, or MPEG card. The MODEM
connector allows the onboard audio to interface with a voice modem
card with a similar connector. It also allows the sharing of mono_in
(such as a phone) and a mono_out (such as a speaker) between the
audio and a voice modem card.
12. GAME/MIDI connector (16-1 pin GAME1)
This connector supports a GAME/MIDI module. If your package came
with the optional USB 2.0/GAME module, connect the GAME/MIDI
cable to this connector. The GAME/MIDI port on the module connects
a joystick or a game pad for playing games, and MIDI devices for
playing or editing audio files.
