Super 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.
