Eight, VxD initialization When VMM Initializes a VxD, do the following: 1, load Real mode initialization section and invoke the real mode initialization process. This process can be done to prevent the Mount VxD from starting Windows, specifying device instance data and selecting pages in memory to Equipment-specific work. 2, load the other segment of VxD to

I recently learned the operating mechanism of the device model and trained books and online materials. it seems that I have modified my network weight. so I wrote down and sorted out my ideas.

Execute PS-A | grep khubd on the terminal, and the khubd process is displayed. This is the hub daemon process. Our device is inserted into the USB interface (whether it is inserted with the hub, after the sub-hub), the daemon detects the issue and then notifies the master controller of the interruption. The master controller then calls the hub detection function to parse the device. After the hub

Recently somehow, the CD-ROM drive and the virtual optical drive letter are missing, see the system found hardware front there is a yellow exclamation point, can not be used, search on the internet, found that a lot of people appear the same problem, just solve the wrong way, looking for two days, finally found a solution: Fixed "optical drive icon missing" record The computer did not use a few days, suddenly found that the CD-ROM icon is missing, the system prompts:

For example, you can write control commands to shut down or restart the machine.

The WIN8 system updates the driver for a device as follows: 1, right click on the desktop space, under the desktop pop-up "All applications" option, left click "All applications." 2, left click "Control Panel". 3, the second way into the "Control Panel" method. Press the Windows and X keys on

Method One 1, double click to open the "Computer" icon; 2, click "Uninstall or change the program"; 3. Select the driver to uninstall (here to uninstall the Intel 1000N Wireless network card driver for example), click the right mouse button, select "Uninstall", follow the on-screen prompts to complete the uninstall.

Although there are already many Linux device-driven development learning articles and blogs on the network, there are many classic Linux devices that drive openHair of the books, writing these posts seems to be of little significance, but the learning process, learning experience recorded, on the one hand has strengthened and consolidatedMeaning, on the other hand, is one of the necessary ways to turn what we have learned into our own income, which is

Method One 1, double click to open the "Computer" icon; 2, click "Uninstall or change the program"; 3, the choice needs to uninstall the driver (here to uninstall Realtek NIC driver for example), find the name with Realtek Ethernet Controller name software, click the right mouse button, select "Uninstall", follow the screen prompts to c

1. Overview L The device model is a new feature introduced by kernel 2.6. It provides an independent mechanism to specifically represent the device and describe its topological structure in the system, so that the system has the following advantages: N code duplication Minimization N provides a unified mechanism such as reference count N you can list all the devi
