9.1 PCI Devices and Functions
The PCH incorporates a variety of PCI devices and functions, as shown in Table 9-1.
If for some reason, the particular system platform does not want to support any one of
the Device Functions, with the exception of D30:F0, can individually be disabled. The
integrated Gigabit Ethernet controller will be disabled if no Platform LAN Connect
component is detected (See Section 5.3). When a function is disabled, it does not
appear at all to the software. A disabled function will not respond to any register reads
or writes, insuring that these devices appear hidden to software.

NOTES:
1. The PCI-to-LPC bridge contains registers that control LPC, Power Management, System
Management, GPIO, Processor Interface, RTC, Interrupts, Timers, and DMA.
2. SATA controller 2 (D31:F5) is only visible when D31:F2 CC.SCC=01h.
3. Prior to BIOS initialization of the PCH USB subsystem, the EHCI controllers will appear as
Function 7. After BIOS initialization, the EHCI controllers will be Function 0.
4. This table shows the default PCI Express Function Number-to-Root Port mapping. Function
numbers for a given root port are assignable through the “Root Port Function Number and
Hide for PCI Express Root Ports” register (RCBA+0404h).
