NOTE:
1. Indicates the number of physical electrical lanes running to a PCIe ® connector.
2. CPU 2 indicates that a second CPU is required to access that specific PCIe ® slot.
3. Default bus assignment (in decimal). Inserting cards with PCI™ bridges may alter the actual bus
assignment number.
4. Slots are enumerated differently based on the operating system. Microsoft® operating systems
enumerate Device ID by bus starting from the lowest bus to the highest.
