If you get a Warning dialog about installing driver that’s not compatible with the hardware. If you have questions on using or adapting this sample for your project, you can either contact Microsoft Technical Support or post your questions in the Microsoft driver development newsgroup. If you run it on a device that’s installed as a miniport, you will get an error message. Now on machine B, you can assume For example, let us say you have a test machine A and another machine B development box.

The Windows XP and Windows Server and later operating systems have exclusive control over the configuration space header, as defined by the PCI Local Bus specification, as well as all of the capabilities in the capabilities linked list.

Accessing PCI Device Configuration Space

Or, you can install the sample in the miniport configuration and browse the internet. However once I have the memory address VirtualI would then like to read and write from kmdd memory. If the ioctl cannot be satisfied immediately, the request is put into a manual parallel queue. Some operations on a peripheral component interconnect PCI device are reserved for the device’s function driver.

The sample has been written in such a way, separating all the hardware specific code in separate modules and isolating them in a subdirectory, it can be easily adapted to work for any PCI and PCMCIA device. I will choose the driver to installand then click Next.

Detail about two different configurations in which these samples can be used is given below. This command lets you terminate active ping threads and close handle to all the device and reenumerate the devices again and display their names with index numbers.

If the machine B has more than one adapter and if the second adapter is connected to the internet Corporate Networkinstead of assigning static IP address to the adapter that’s connected to the test machine, you can install Internet Connection Sharing ICS on it and get an IP address for ICS.

The following code example shows how to query for the power management capability data of a device: Real driver for network devices should be written using NDIS.

This included a keyboard driver Interrupt driven hard disk driver command line console file system gaphical windows manager. But then this approach delays the system boot because the devices are powered up serially, waiting for the S0 IRP sent on a device to be completed before moving on to another device. That data will come from an IORequest Buffer.

If the build succeeds, the driver will be placed in the binary output directory specified for the build environment. If a device does not have an extended configuration space or the platform does not define a path for an extended configuration space on a device, the read requests will return 0xFFFF and the write requests will have no effect.


This sample provides an example of a minimal driver intended for educational purposes. This allows the system to complete resuming while the driver performs device-specific re-initialization in the background. Toaster Framework-based versions of the WDM toaster sample drivers. Sign up using Email and Password. Drivers must not attempt to modify these registers. Read Boot-Time tracing section in this document for more information on how to enable that.

Home Timeline Software Company Info. Product feedback Sign in to give documentation feedback. The choice of Intel Ethernet Adapter is made because the hardware is relatively inexpensive, easily available, supports advanced hardware features such as scatter-gather DMA, full fledge power management – ability to wake the machine on external event Wait-Wakeability to power down the device when not in use Idle detection – hardware specification is publicly available, and the source code to interface with the hardware is also available in the DDK.

Sign up using Facebook. This number will be used in identifying the interface when you invoke ping dialog. Post as a guest Name. Pck then protocols can bind and perform network transfer. As a result, it is better to connect the network device to a private hub and ping another machine connected to that hub.
