Figure 2.  Back Panel Audio Connectors 
 
NOTE 
The back panel audio line out connector is designed to power headphones or amplified 
speakers only.  Poor audio quality occurs if passive (non-amplified) speakers are 
connected to this output. 
Legacy Input/Output (I/O) Controller 
The legacy I/O controller provides the following: 
•  Two serial ports (one via a back panel connector and one via an onboard header) 
•  One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port 
(EPP) support via a back panel connector 
•  Serial IRQ interface compatible with serialized IRQ support for PCI systems 
•  PS/2-style keyboard and mouse ports 
•  Intelligent power management, including a programmable wake up event interface 
•  PCI power management support 
The BIOS Setup program provides configuration options for the legacy I/O controller.
