Special Device and Function Routing
All devices in the Intel® 5000X chipset MCH reside on Bus 0. The following table
describes the devices and functions that the MCH implements or routes specially. The
DIMM component designator consists of a three-digit code: the first digit is the branch,
the second digit is the channel on the branch, and the third digit is the DIMM (FB-DIMM
command “DS” field) on the channel.
Functions Specially Handled by the MCH
To comply with the PCI specification, accesses to non-existent functions, registers, and
bits will be master aborted. This behavior is defined in the following table:
