Direct Media Interface (DMI) RCRB
6 Direct Media Interface (DMI) RCRB
This Root Complex Register Block (RCRB) controls the (G)MCH-ICH7 serial interconnect. The
base address of this space is programmed in DMIBAR in D0:F0 configuration space. Table 6-1
provides an address map of the DMI registers listed by address offset in ascending order.
Section 6.1 provides a detailed bit description of the registers.
Note: All RCRB register spaces need to remain organized as they are here.
