2.5.8 AI Slot Detector
This motherboard comes with on-board LEDs that light up when the PCIE/
PCI devices are not correctly installed. This is a reminder that you should
reinstall these devices. Refer to the figure below for the location of the LEDs.
• If you install two VGA cards, we recommend that you plug the rear chassis
fan cable to the motherboard connector labeled CHA_FAN3 or CHA_FAN4
for better thermal environment. See page 2-32 for the connector location.
• Some PCI Express devices cannot operate on x4/x1 mode.
