I'm currently building a user mode application that need to know the "resource map" (i.e. the I/O map and memory map) of windows 2K/XP. I need to know how to obtain the I/O space or memory space that is consumed by PCI devices. This is needed since we can not invoke the BAR (base address register) sizing algorithm from within windows, if we attempt to do so, the system will eventually or directly hang. I presume that this information is available from the PnP manager of win2K/XP, but how to do it :?

Thx in advance
