3.2.4
BIOS 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 has started regularly 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.
