2.2.4.1Super I/O (U28)

The Super I/O device (SIO) is an SMSC LPC47B272 enhanced Super I/O controller. The SIO connects to the ICH3 through its LPC bus connection. The SIO provides support for the front panel serial port (J17, see page 80). There is no front-panel connection to the legacy keyboard and mouse PS/2 ports. Keyboard and mouse support are provided by the USB connection (J12, see page 87). See Figure 13 for connector locations.

To facilitate debug and BIOS development, SIO connections such as legacy (PS/2) keyboard/ mouse and floppy may be provided on initial board revisions. Software must not rely on the presence of these connections on future board revisions.
