[RajeshSE]

Hi,
I wrote the Device Drivers for PCI Card in C.It is working fine now.But i want the same driver is going to work in PCI Express Card.So I want it to write in Memory Mapped I/O.Can anyone suggest me to help regarding this?

AFAIK, this is transparent for driver deleloper. This means, it doesn't matter whether device is PCI or PCI Express card.
Anyway, the best place to get information about Windows driver development is http://www.osronline.com/
