Table 3: Cardbus/PCI configuration space default values
1
For cardbus applications, the PC Card Standard 7.x defines these fields as “Allocated”. However, for cardbus support in
Windows, these fields need to be defined to fully support the PCI configuration Space.
2
For cardbus applications, the PC Card Standard 7.x defines these fields as “Reserved”. However, for cardbus support in
Windows, these fields need to be defined to fully support the PCI configuration Space.
3
Relocate is a bit in the local configuration registers that can locate the start of the cardbus information structure at DWORD18
or DWORD 32 in the PCI configuration region. This bit is writable only via the optional EEPROM. The default state is 0, so the
CIS is available at DWORD18 in the PCI configuration region.
