While defining legacy PCI compatible mode and O.S., this kind of (0-fff) space is not available. 0-3f is PCIe Compatibility Configuration Space. PCIe Capability Structure determines if Entended Configuration space for PCI is present or not. SpletThe extended configuration space of the PCIe bus stores some of the Capability structures unique to the PCIe device. The PCI device cannot use this space. In the x86 processor, the config_address and config_data registers are used to access 0x00-0xff, while the ECAM method is used to access the space of 0x000-0xfff.
