enumerate PCI devices in WDM

How I could enumerate PCI devices and get vendor ID, matching BusNumber
and SlotNumber with the list of PCI devices, using WDM model and numega
driver studio(version 2.6)?

WDM does not support such functionality.
In SoftICE, type PCI.
In WinDbg, type !pci.

Leandro,

You can always do i/o directly to the bus, take a look at Shanley’s
PCI book edited by Mindspring. You’re going to have to use some
kind of lock to keep other processors out of it between the time
you write to the control register and the time you read from the
data register, but that’s a small inconvenience. In Linux there are
macros cli( ) and __cli( ), but in Windows you may be on your own.
This is not that bad if all you’re doing is to read the bus, but if you
want to use it to write the bus, know what you’re doing ! There are
sharp corners all over that track.
