motherboard drivers

If we are ready to assemble the computer DIY, then we first need to determine their own needs, confirm the use of computers, and then according to their own budget to determine the price of the machine. In addition to determining the price and performance of the machine, one thing we need to determine is the size of the machine. The choice of host size is mainly based on two reasons, one is to place the host space, the other is a personal preference. Some people like behemoths, some like small a

How to use the device tree of linux drivers and how to use the device tree of linux drivers The Device Tree describes the hardware from the software perspective, and DTS is the Device Tree source file. DTC is responsible for converting DTS to DTB, and DTB is the binary form of DTS for machine use. The Device Tree is a tree structure. Each child node except the root node has a unique parent node, which can h

Intel's sixth-generation Skylake processor requires a 10-series motherboard, while the 10-series motherboard has Z170, B150, H170, H110, and C232 motherboards, B150 positioning the mainstream, C232 mainly with the six major server boards. So these two processors are different, small series in the computer Configuration B150 platform recommended many netizens commented that why not choose V5 Processor, and c

So, how do I get the motherboard jumper? In fact, it is very simple, we just have a reason to think, one by one, it is easy to connect. Generally speaking, the main board jumper on the needle mainly includes switch power switch, reset switch (coincidence), power light, hard drive lights, speakers, audio, USB interface, and so on, seemingly a lot, but one to, it is not difficult, the following detailed introduction. How to connect the cha

1 BIOS chipThe BIOS (basic input Output system) is a basic input U-out system that serves the hardware in your computer. The BIOS is a read-only memory that contains the system boot program, the drivers for the hardware devices that are required for system startup, and the basic hardware interface device drivers. Currently, the BIOS chip in the motherboard is mai

device in the private_data member that represents the opened file pointer filp for other operation functions. Release Operation: int yjpLED_release(struct inode *inode, struct file *filp){filp->private_data = NULL;return 0;} Release the content allocated by open in filp-> private_data. Write operation: ssize_t yjpLED_write(struct file *filp, const char __user *buf, size_t count, loff_t *f_pos){ssize_t retval;struct yjpLED *dev;dev = filp->private_data;if(down_interruptible(dev->sem))return -ERE

Poll for linux drivers and poll for linux driversPOLL operations 1. POLL execution process: Poll is a system call. Its kernel entry function is sys_poll. sys_poll calls do_sys_poll directly without any processing. The execution process of do_sys_poll can be divided into three parts: 1. Copy the input pollfd array to the kernel space. Because the copy operation is related to the array length, this is an O (n) operation, in do_sys_poll, the code in this

This document describes how to use ctl_code to communicate with a Windows NT driver. generally, user-Mode Applications can communicate with kernel-mode drivers by calling createfile and deviceiocontrol, if a driver in the kernel state wants to perform similar operations with another driver, how can this problem be achieved? Next, we will provide a detailed description. The main idea is to first get the handle of another driver, then construct an IRP,

overheating. Solution: To take overclocking should be reduced frequency, over-temperature should be cooled. In fact, not all of the failures are so complex, sometimes from a simple aspect of consideration, can also be a good solution to the problem  to learn analogy. All things to nip in the bud, the following is the author summed up some of the experience available for your reference: 1 regularly to the important registry files for manual backup, to avoid system errors, can not be replaced

What is the difference between a H67 motherboard and a H77 motherboard? As shown below: H67 and H77 The difference is big, I want to buy a can use Ivy Bridge processor motherboard, is going to buy a new i5 3550 of the processor, want to know with the motherboard to choose which Compare the price H67 and H77 The diffe

is not available, requiring a restart of the computer. When restarted, it sometimes works properly and sometimes goes into safe mode. If you go into safe mode and restart your computer again, it will work. But shutdown one night, and then turn on the fault again, using a variety of anti-virus software are reported no virus, Reload win 98 can not solve the fault. Because the machine can start normally and go into safe mode, it is estimated that the device that is loading the driver is out of th

Lenovo G31 Motherboard does not boot how to do Lenovo G31 Motherboard does not boot the solution one: Can be divided into three kinds of situations: The first is power after the black screen, there is no self-test of the "lap" and self-test error of the bell, this situation shows that the motherboard system does not work, to check the power is normal, the CPU

The motherboard diagnostic card is also called the post card, which is an essential tool for mainboard repair. Every time the motherboard BIOS is started, all components of the system, such as the circuit, memory, keyboard, video, hard disk, and soft drive, are strictly tested and analyzed, initialize the configured Basic I/O settings, and import the system to the operating system after the configuration is

administrator. Uninstall the driver, go to "Add Remove Program" in Control Panel, uninstall all related drivers, and reboot. To disable ACPI, right-click on my Computer--manage--Device Manager--"Computer"--"advancedconfigurationandpowerinterface (ACPI) PC". 　　Step Three: Right--Update drive--select "From list or position"--next--"Do not search my own choice"--Next--select "STANDARDPC" and then determine that the system will be prompted to restart t

Under Windows 9x, drivers can be divided into sound card drivers, graphics drivers, mouse drivers, motherboard drivers, network device drivers, printer

", to view the "properties", found that both of the device drivers are not properly installed, so the author concluded that the problem is here. Need to explain: PCI bridge is "PCI Bridges", mainly for the Eide interface between the high-speed connection between the channel, so that the Eide interface to better support high-speed data transfer mode (that is, Ultra DMA 33), in order to significantly improve the Eide interface transmission speed (in ge

ASUS Motherboard Light can't start solution Reason Analysis and solution: If we press the power button, only the power indicator light, the computer screen without any reflection, there is no alarm sound; So how should we solve this situation? The screen is not displayed, there is no alarm sound, we can not from the post self-test function to get the appropriate information; As we all know, the computer is a complex and sophisticated product mix, s

I. No display at startup No display is displayed when the microcomputer is started. The first consideration is BIOS. The BIOS of the motherboard stores important hardware data, which is also a delicate part of the motherboard and is vulnerable to damage. Once damaged, the system may fail to run, this type of fault occurs generally because the BIOS of the motherboard
