Memory Proximity Reporting for I/O

Use this option to set whether the system ROM reports the proximity relationship between I/O devices and system memory to the operating system. Most operating systems can use this information to efficiently assign memory resources for devices, such as network controllers and storage devices.

NOTE:

Certain I/O devices might not be able to take advantage of I/O handling benefits if their OS drivers are not properly optimized to support this feature. For more information, see your operating system and I/O device documentation.
