How to configure the general purpose PCIe port on QM57 from PCIe X1 to PCIe X4 on SOM-5788?
Answer: Advantech can achieve this changing in PCI express ports but requires using customized BIOS. There is no selection item in BIOS setup menu to configure the PCI express lane depth. Therefore, if PCIE X4 port is needed, please contact Advantech FAE or sales respresentive for BIOS customization.
