Hi, I have written a filter driver for a regular PCI-to-PCI bridge (
actually this is a i960RN PCI card which has a secondary PCI bus on it).
The system recognizes this as a P-to-P device and installs pci.sys as the
driver for it. That sounds good. I have written my driver and I am running
into problems running the INF file on it.
The PCI vendor id for this device is 8086(intel) and the device id is
0964. I have reproduced the INF file below. Could someone take a look at
it and let me know if this INF file would actually install my driver as
the filter driver for the PCI-to-PCI bridge?. For the life of me, I cannot
figure out why my driver’s DriverEntry does not even get invoked.
All I want is to play with some configuration space registers that are not
visible to the OS by default.
PS :- I got this INF file from the apg440 driver in the win2k DDK. The
driver in the samples also installs as an upper filter driver so I thought
I will modify it to suit my own purposes. I ran the agp440.inf file
through chkinf and it gives a couple of errors and some warnings. The
chkinf tool does the same on my inf file as well so I thought it was no
big deal. Obviously since I copied this from the agp440.inf, I have not
bothered to replace the comments with my own.
I would appreciate any help.
Thanks,
RK
