This article is a thesis of the Operating System Course written by Yang Zhao (software College of Xi'an University of Electronic Science and Technology). According to his introduction, at present, there is almost no information on the principle of plug-and-play on the Internet. He wrote this paper in reference to a Ms document and hoped to be useful to readers.PNP (Plug and Play, plug-and-play) means that users do not have to intervene in the distribution of system resources by peripheral device

A hardware can have only one PDO, but multiple fdo. In the driver, the corresponding PDO and fdo are not the hardware. In terms of user-state and kernel-State communication, the system packs an IRP structure for each user request and se

In order to resolve this device conflict, we can follow the following steps to set up: First in the Settings window will be COM2 screen, and forced to interrupt the network card to 3; If you encounter a PCI interface network card and video card conflict, we can use do not assign IRQ to display card solution, is to set the Assign IRQ for VGA in CMOS to "Disable".

Here is a tip: if you do not set your machine name, x windows will wait for a long time for the first time, only a gray screen and X-type cursor will appear, just like a crash. Please be patient and try drinking water or smoke a cigarette. Of course, the direct method is to set your machine name, edit/etc/host

MSDN Original:https://msdn.microsoft.com/zh-cn/library/windows/hardware/ff554721 (v=vs.85). aspxIn Windows, a device is represented by a device node in the Plug and Play (PnP) device tree. Typically, when you send an I/O request to a device, some drivers help handle the request. Each of these drivers is associated with a device object that is arranged in the stack. The order of device objects is called the device stack along with their associated driv

3 If you use this card under WINDOWS98, you can use the Device Manager settings card, and then use Loadlin hot boot into Linux to determine Windows98 and Linux using the same set parameters.
4 If in DOS with this card, you can use the Sound Blaster card 16PnP card attached to the ICU utility, set in DOS, and then with Loadlin hot boot into Linux, to determine the DOS and Linux with the same set parameters.
The commercial version of the OSS sound driver supports Sound Blaster 16PnP, whi

3) if this type of card is used in Windows 98, use the Device Manager to set the card, and then use LOADLIN to start the card in Linux. Make sure that Windows 98 and Linux use the same set parameters.
4) if this type of card is used in DOS, you can use the icu public program attached to the 16PnP card of the audio card, set it in DOS, and then use LOADLIN to start
first, the basic concept
Its main function is the current amplification (analog circuit) and the switching function (digital circuit).
The transistor consists of two PN structures, and a common electrode becomes the base of the transistor (denoted by the letter B). The other two electrodes become collector (denoted by the letter C) and emitter (denoted by the letter e). Due to different combinations, a kind of transistor with NPN type is formed, and the other is

Set the NIC correctly
If the network media is correct but cannot be connected, return to the NIC settings. Check whether there are device resource conflicts. If there are many conflicts, there are not all prompts. Possible device resource conflicts include: The NE2000 compatible nic and COM2 both use IRQ3
First, the multimeter to the test diode end, with the multimeter of the Red pen to one of the transistor's pin, and the other side of the multimeter to test the remaining pins, until the following results are tested:
1, if the transistor's black form pen to connect one of the pins, and the Red Watch pen to test the other two pins are on the voltage display, then this transistor is PNP transistor, and the black pen is connected to the foot of the tran
. attributes are like member variables in C ++ classes, the method is like a member function in the C ++ class. An event is a callback function;
2) whether it is a kernel-mode driver or a user-mode driver, it is constructed using the same object model and carries the same base. This is based on WDF. WDF includes kmdf and umdf, both of which inherit WDF, regardless of the Framework, internal encapsulation method or WDM.
3) the WDF Driver Model encapsulates many common functions, such as

Set the NIC correctly
If the network media is correct but cannot be connected, return to the NIC settings. Check whether there are device resource conflicts. If there are many conflicts, there are not all prompts. Possible device resource conflicts include: The NE2000 compatible nic and COM2 both use IRQ3 and (Realtek RT8029) PCI Ethernet NIC and display card "like" IRQ10. To solve the conflict, follow these steps: first, block COM2 in the settings window and forcibly set the NIC in

When you are sure that the network media is not a problem, but still cannot be connected, return to the network card settings. See if there are conflicting device resources, and there are many times when conflicts are not always prompt. Possible device resource conflicts are: NE2000 compatible NIC and COM2 are in conflict, all using IRQ3, (Realtek RT8029) PCI Ethernet network cards and dis
