Technical Reference Guide
The register index (CF8h, bits <7..2>) identifies the 32-bit location within the configuration space
of the PCI device to be accessed. All PCI devices can contain up to 256 bytes of configuration
data (Figure 4-3), of which the first 64 bytes comprise the configuration space header.

Each PCI device is identified with a vendor ID (assigned to the vendor by the PCI Special Interest
Group) and a device ID (assigned by the vendor). The device and vendor IDs for the devices on
the system board are listed in Table 4-2 (NOTE: Only device IDs that are implemented in these
systems are listed. nu = not used. n/a = not available).
