PCI_ENABLE_PARITY for PCIs

NTFSD
1

Hi all,

I am very new to DRIVER space and I am trying to set the PCI_ENABLE_PARITY command on all available PCI adapters in W2K and WS03. This is to enable parity checking on the data each PCI transfers to maintain data integrity.

Any help to develop a functional driver to accomplish this task is much appreciated. I did start up with HalGetBusData and HalSetBusData, that didn’t work well for me. These API’s are deprecated and found that the article http://support.microsoft.com/support/kb/articles/q253/2/32.asp http: has the answer. The problem in using the interface is that I don’t have PDOs for each PCI to supply to those interfaces. I would appreciate help in creating PDOs for each PCI adapters on a system so that I can then use the above URL’s interface to read and write into the Config Space.

Frankly am I doing the right thing by using the PCI_COMMON_CONFIG to enable the parity checking?

Thanks

There’s nothing wrong to turn on the PARITY check on the device you own.

You write a functional driver for your PCI adapter. You will get the PDO
created by the PCI bus driver in your AddDevice routine. Then you can send
PNP commands to RW the PCI config space preferably after you had received an
IRP_MN_START_DEVICE.

If you were writing a driver from scratch, I’d recommend using the WDF
interface.

HTH,

Only, problem is the framework still appears to be highly in flux. So using
WDF right now, means you will have to rewrite in the future.
