Question #372:

If QNX is booted with PnP enabled in the BIOS, starting of the Photon GUI fails with the following error message: "io-display is not running"
If QNX is booted with PnP disabled, the Photon GUI works. What's wrong?

If QNX is booted with PnP enabled in the BIOS, QNX does recognize (according to the QNX "pci" tool) the ethernet controller(s), but the network does not work correctly.
If QNX is booted with PnP disabled, network is working. What's wrong?

Answer:

The PnP enumerator of QNX seems to handle PCI bridges with sub-type "PCI (4)" only, but completely ignoring sub-type "HOST (0)".

Add the following line (below the existing "device(pnpbios, ...)") to the "/etc/system/enum/devices/bridge" file:
device(pnpbios, .type=$(PNPBIOS_TYPE_BRIDGE), .subtype=$(PNPBIOS_BRIDGE_HOST))

Question #369:	I'm having some troubles to get one or both of the serial lines to work. Whatever I tried, nothing is transmitted nor received on this interfaces.
Answer:	Chances are that the serial port modules (SERIF) are not installed in your CEC. As written in the "Serial Connector(s)" chapter of the corresponding "CECx Technical Reference Manual", these modules are optional. If you did not order these modules preinstalled in the CEC, you can order them belatedly.

Question #361:	Two USB ports of the CEC are not working if a Low- or Full-Speed USB device (like keyboard, mouse, floppy, ...) is connected. But any Hi-Speed USB device is working properly. What's wrong?
Answer:	You are using a CECx-11, correct? As written in the CEC User Manual", 2 out of the 7 USB ports support USB 2.0 only. For more details, please check the manual.

Question #360:	The CEC seems to boot normally and works properly afterwards but there is nothing displayed on the screen.
Answer:	Is an analog monitor connected to the CEC? As written in the CEC User Manual", the CEC supports DVI-D only! Please check again using a digital monitor.
