PCI devices

[King64]

Hi guys, lately I am interested in PC hardware, especially for detecting and setting of PCI devices. Surfing on the web, I found phymem.dll, an interesting dll which should read and write from/to PCI devices and other things. So I wrote a simple program to take advantage of the functions exported by the dll. Unfortunately the nice dll doesn't its job about PCI devices. Any suggestions would be greatly appreciated.
