.B setpci
is a utility for querying and configuring PCI devices.
-To make use of all the features of this program, you need to have Linux kernel
-2.1.82 or newer which supports the /proc/bus/pci interface. With older kernels,
-the PCI utilities have to use direct hardware access which is available
-only to root and it suffers from numerous race conditions and other problems.
