4.4 PCI Express x16 Graphics Slot
A PCIe x16 graphics slot is provided for insertion of PEG graphics cards.
Depending on the chipset the PCIe signals are multiplexed with SDVO signals, thus
SDVO modules can be run in this slot as well. SDVO or PCIe graphics will be activated
automatically via PullUps of the SDVO I²C interface on the SDVO module.
