Many times when debugging both PCI hardware and software it is very useful to easily be able to browse the available PCI devices in the system without having to use WinDbg or a similar kernel debugger. The PCI Explorer application enables you to graphically view all the PCI devices and the buses they reside on accordingly to the actual hierarchy of the various devices on the buses. The PCI Explorer application also enables you to easily edit memory, I/O registers and Configuration Space Registers assigned to any PCI device in your system.
