PCItree is a graphical Windows tool to look at all the hardware devices of the PCIbus. The devices are displayed in a tree like view. Information about the devices and its vendors is obtained from a seperate database. PCItree gives you read and write access to the config registers of each device and even to each device's memory given by the BAR.
This tool helps you to figure out problems with your PC, or lets you debug your custom PCI chip.
