Hi

I wrote message couple days before but i didn't receive any answer.
I'll try to get more details for the problem.

I'm writing application and driver for PCI/PCI Express extender (like
this one: http://www.amfeltec.com/index.php?id=1&subid=6 www.amfeltec.com/index.php?id=1&subid=6>). The extender is used for
testing/debugging PCI/PCI Express cards.
The application is execute IOCTL call to my driver that reads PCI/PCI
express configuration registers (PCI_COMMON_CONFIG structure) of
tested card (there is no connection between my driver and driver of
tested card). Than, the user can switch off the extender and remove
the tested card from the extender. After this, the user can put back
tested card and restore PCI/PCI Express configuration register using
my application by executing call into my driver. At this point, the
user can use the tested card as before.
