Additional Information PCI port
The PCIe menu refers to the different PCIe lanes using their chipset based numbers. For
every lane, the number used on the COMe connector is mentioned. Take care to select the
PCIe lane you require as numbering varies strongly.
The standard layout for PCIe consists of 8 PCIe x 1 lanes. Other layouts may be programmed
by flashing a different descriptor to the Intel firmware on the BIOS SPI flash. Contact
Kontron Support if you require a different PCIe layout with your project.
The PCIe BIOS layout for COMe PCIe lanes consists of a default BIOS built to fit most
customer applications and offers two additional BIOS binaries for further common PCIe
layouts.
