Ethernet (Cardbus) Card detection.

Hi All,

I need a small doubt to be clarified regarding the Cardbus
Ethernet card detection on Windows-2000. I just wanted
more information on how the Cardbus detection is done in
Windows-2000. Like how exactly the configuration of
cardbus is read and how exactly it enumerates these device.
If any one can point me to some URL or explain me it would
be of great help for me.
one more thing is that i wanted to know whether windows-
2000 detects the PCI Devices by polling method or by some
interrupt mechanism for each slot?
Hope i will get some guidance on this.

Thanks & Regards,
Vishwanath Maram
