PCI resource detection problem in Windows XP
vasanth <vasantharajg[ at ]nestec.net> 16.05.2007 10:19:29
Hi!

We have a problem in PCI driver development with Windows XP SP2. The
problem is that windows is not assigning memory mapped IO address to
the PCI card. My bus-mastering capable card requires 3 memory IO
addresses for 512, 2M and 8M bytes. I dumped the PCI config space
using pci32.exe utility and found that the address is assigned there.
But windows is showing only the IRQ assigned in the resource tab from
the device manger. In my sample driver (on top of PCI) we tried
printing the resource list (while getting IRP_MN_START_DEVICE) and
found that only the IRQ is assigned ( the assigned IRQ matches with
the pci dump created as explained earlier). Also when took the pci
dump from linux and got the same base adresses for the memory space.
Please help me how to make windows detect the resource for my card.

thanks in advance,

regards,
vasanth.
