Notes: PCI can be defined by configuration mechanism 1 or 2. However, mechanism 2 is deprecated as of PCI version 2.1; only mechanism 1 should be used for new systems. The Intel "Saturn" and "Neptune" chipsets use configuration mechanism 2.

Bitfields for PCI configuration address port: Bit(s) Description (Table P207) 1-0 reserved (00) 7-2 configuration register number (see #0597) 10-8 function 15-11 device number 23-16 bus number 30-24 reserved (0) 31 enable configuration space mapping Configuration registers are considered DWORDs, so the number in bits 7-2 is the configuration space address shifted right two bits.
