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
). 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
).
See
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.
