ADD2 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
nd
2
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.
