4.6.2.3ADD2 Slot

When not being used for PCI Express, the x16 slots can be used for Serial Digital Video Out (SDVO), which is also sometimes referred to as ADD2 (Advanced Digital Display

2nd generation). SDVO cards provide for a third party vendor secondary graphics add- on such as a digital panel interface. It is important to note that the Mobile Intel® 915GME Express Chipset does not support lane reversal of its SDVO interface and since the slot is routed lane reversed, a special SDVO card which un-reverses the lanes must be used. These cards are sometimes referred to as ADD2-R (“R” for reversed) cards.

Note: ADD2-N (“N” for normal) cards are not compatible with the board.
