PCI Sniffer scans all PCI busses in the computer and detects automatically which devices are present. You can comfortably browse the detected devices and list all functions of these devices in a detailed display. Since the installed operating system will not be booted, it has no possibility to alter the configuration, thus allowing you direct access to the data. This makes it possible to detect resource conflicts and solve them. Even if your computer runs problem-free it is often interesting to know which devices are installed.
