IR Receiver
The UDOO BOLT board embeds an IR receiver, which allows using a remote control when the board is placed in an enclosure (like, i.e., on Set Top Boxes).
The Infrared Receiver is SMD Type, p/n TSOP75238TR, and works with 38kHz carrier frequency.
The IR port is managed by the embedded microcontroller.

UEFI BIOS Default Restore switch
In some cases, a wrong configuration of BIOS parameters could lead the module in an unusable state (i.e. no video output, all USB HID devices disabled).
For these cases, on the module it has been placed a 3-way switch which can be used to restore the BIOS to factory default configuration. To do so, it
is necessary to place the contact of the switch in 1-2 position, then turn on the module, wait until the board resets itself then turn off the module. The
contact MUST be now placed back to 2-3 position.
During normal use, the contact MUST be always placed in 2-3 position.
