Infrared Header (IrDA)
This connector supports wireless transmitting and receiving. Before using this function,
configure the settings for IR Address, IR Mode and IR IRQ from the “INTEGRATED PERIPH-
ERALS” section of the BIOS.
Audio Connectors (CD_IN1, CD_IN2, MODEM)(Optional)
CD_IN1 and CD_IN2 are Sony standard CD audio connectors, each of them can be
connected to a CD-ROM drive through a CD audio cable. The Modem_IN connector allows
the onboard audio to interface with a voice modem card with a similar connector. It allows
connecting the mono_in (such as a phone) or mono_out (such as a speaker) between the
onboard audio and the voice modem card.
