Q: Through the short-circuit motherboard of the CMOS jumper to clear the BIOS set the power-on password, you can repeatedly set the jumper status to short-circuit location, after the boot found that the password still exists. How can i solve this problem?A: From what you said, you should be in the short of the CMOS jumper, did not cut off the motherboard's power

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 intro

If you forget the password to enter the CMOS Setup program, in addition to using the jumper short removal method on the motherboard, you can also use the method of software removal, this article has sorted out the five methods of eliminating the CMOS password under DOS. Open the chassis, locate the battery on the motherboard, disconnect it from the motherboard (that is, remove the battery), and the CMOS will lose all information stored internally bec

In the advanced main menu of the BIOS, the first item is an ASUS motherboard-specific option jumperfree, which means jumper-free. Other manufacturers recommend products are basically the project, but the name is generally Jumperfree Configuration. After entering the jumperfree configuration option, you can see a lot of content. The following options are generally available. 1.Ai overclock Tuner: Manual only overclocking (recommended set to Auto). 2

Connect to the chassis When installing the motherboard, many readers do not need to put the motherboard into the chassis and fix it, but how to use the chassis connection line! Next let's take a look at the chassis connection line -- ① The

responsible for the maintenance of the operator, the client cabinet is mainly by the customer's own maintenance, or co-operation with the operator to maintain.IDC's managed data center focuses on physical link maintenance by adding physical link and link troubleshooting. The connection jumper completes the work order task by allocating the original idle link, and the alarm is removed by switching the link and inserting the

the trunk cable in the park. This article focuses on a type of testing method that is widely used to verify the performance of optical fiber cabling systems. Purpose of Reference Value Setting The types of optical fiber connectors for each project are different, and the models of the tested links are also different. To increase the flexibility and operability of the test and reduce the wear and tear of the light source and optical power meter ports during the measurement process, an important s

, Fluke Cable certification integrated Cabling System tester at the same time to obtain the accuracy of these two institutions certification, the investment for customers, is a good protection. Two, why should fluke use that "expensive" adapter Some manufacturers have introduced the Integrated Cabling System test scheme without adapters, and the principle is to set reference values in reference to the optical fiber integrated wiring system test method. Theoretically, it does have its own uni

cable factory, has introduced a number of production lines for a number of foreign brand products for domestic fixed-point OEM production, in the IT industry jargon, this is called OEM. I have been invited to visit some of these plants, found that many foreign brands of twisted-pair (including five, five and six categories) are in this production, the same production line made of products, brand different, the price difference is also very large, OEM products are usually the original brand prod

principle of designing an electronic distribution frame, that is, to help network administrators manage the wiring system. When talking about management, the first step is to have a link database. No matter whether the database is written on paper or stored on a computer disk, it is impossible for network administrators without this database to talk about wiring management. In the face of the wire distribution frame of the webshell, the network administrator will feel a sigh of relief. However,
