3. If you have a CR100-PCIE16 carrier board, insert a PCI Express graphics card into the PCI
Express x16 graphics slot.
4. The 2-pin boot BIOS selection header specifies whether the system will use the BIOS on
the carrier board or the BIOS on the module when booting:
• Pins 1 and 2 open (default)—The system will boot from the COM Express module BIOS,
which is based on the Phoenix
extensions.
• Pins 1 and 2 jumpered—The system will boot from the carrier board BIOS.
Refer to the Procelerant CR100 FlexATX Carrier Board Product Manual if you plan to install a BIOS chip
on the CR100 carrier board.
5. Connect the power supply to the 24-pin ATX PSU connector on the CR100 carrier board.
The power supply connector must be a 24-pin or 20-pin
Specification Version 2.2.
6. Connect the power switch and LED indicator cables to the front panel I/O header. Pin #1 is
marked by an asterisk (*) on the CR100 carrier board.

The CR100 carrier board does not support the power LED indicator. If you have a custom carrier board
that supports this function, make sure that you connect the cathode and anode of the power LED cable
correctly.

If a 20-pin cable is used, plug the 20-pin cable in to the pin #1 end of the connector, and leave the
two pairs of pins on the other end exposed. No adaptor is required. Pin #1 is marked by an asterisk
(*) on the CR100 carrier board.
