The board provides four internal SATA connectors through the PCH for internal 
storage. 

The PCH provides independent SATA ports with a theoretical maximum transfer rate of 
3 Gb/s per port.  A point-to-point interface is used for host to device connections. 

The underlying SATA functionality is transparent to the operating system.  The SATA 
controller can operate in both legacy and native modes.  In legacy mode, standard IDE 
I/O and IRQ resources are assigned (IRQ 14 and 15).  In Native mode, standard PCI 
Conventional bus resource steering is used.  Native mode is the preferred mode for 
configurations using the Windows* XP, Windows Vista*, and Windows 7* operating 
systems.

The Legacy I/O Controller provides the following features: 
•  One serial port 
•  One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port 

(EPP) support 

•  Serial IRQ interface compatible with serialized IRQ support for PCI Conventional 

bus systems 

•  PS/2-style keyboard/mouse interface 
•  Intelligent power management, including a programmable wake-up event interface 
•  PCI Conventional bus power management support 
The BIOS Setup program provides configuration options for the Legacy I/O controller. 

The serial port is implemented as a 10-pin header on the board.  The serial port 
supports data transfers at speeds up to 115.2 kbits/s with BIOS support.
