Installing drivers for PCI card with same signature for more than 1 card in windows-xp

Hi All,

I have developed drivers for PCI card in windows-xp.I am able to install for 1 PCI card , but i am unable to install for second card with same signature (VendorId and DeviceId ).How can i change the installation inf file.

Please help me regarding this issue.

Thanks in advance.

I don't write windohs drivers, but isn't that up to the driver? The driver should see two different pci bus addresses and act accordingly. The PID and VID aren't enough to uniquely identify anything.

I can't think of anything in the INF file that determines how many devices the driver will support. You should be able to simply install the driver twice.

Regards,

Not sure with PCI but with USB (which has vendor and product id) there is also a serial number field.

Nope; no serial # in PCI. One uses the slot number to tell identical cards apart during configuration.
