Functional Description
10.3.2.3
PCI Express* and Internal Graphics Simultaneous
Operation
10.3.2.3.1 Standard PCI Express* Cards and Internal Graphics
BIOS control of simultaneous operation is needed to ensure the PCI Express is
configured appropriately.
10.3.2.3.2 MEDIA EXPANSION Cards (Concurrent SDVO and PCI Express*)
SDVO lane reversal is supported on the GMCH. This functionality allows current SDVO
ADD2 cards to work in current ATX and BTX systems instead of requiring a separate
card. The GMCH will allow SDVO and PCI Express to operate concurrently on the PCI
Express Port. The card that plugs into the x16 connector in this case is called an Media
Expansion card. It uses 4 or 8 lanes for SDVO and up to 8 lanes of standard PCI
Express.
For the GMCH, the only supported PCI Express width when SDVO is present is x1.
This concurrency is supported in reversed and non-reversed configurations.
Mirroring/Reversing is always about the axis.
