2.4.12.2 BIOS defaults
The BIOS comes with a set of configuration parameters when shipped by Advantech referred
to as “Optimized Defaults” or “factory defaults”. The user can change BIOS settings via the
setup menu either temporarily or permanently by saving the changes as “User defaults”.
The BIOS loads Optimized Defaults by the option “Restore Defaults; and loads User defaults
by the option “Restore User Defaults”. If no User defaults have been defined, the BIOS will
do nothing.
2.4.12.3 PCIe Tree
The BIOS also performs an enumeration of all PCIe resources, builds a bus/device map
and assigns resources to the PCIe devices. Most OSs performs a reallocation of
resources during start up. However, the PCIe bus/device map will not be changed by
the OS. The table below gives an overview of the PCIe devices and their
corresponding system function:
DMI2 x4 Link from Processor to PCH

Express* Port 1
