to start the machine, there are two ways to purge frequency settings, one is to clear the CMOS settings (for the way you can set the CPU operating frequency in the CMOS), as long as the CMOS purge jumper is found on the motherboard (typically, next to the motherboard battery, for the 13-pin jumper), after the CMOS is removed, Re-restore the jumper position to re

debug copy to the boot disk transport The specific actions are as follows: C:>debug ―o 70 10 ―o 71 01 ―q 　　Two. When overclocking does not boot up or enter the system or previously in the CMSO setting, set the security option to system, which can be used to discharge the CMOS. (1) Use CMOS to clear jumper Turn off the power, open the chassis, and locate the CMOS removal jumper on the motherboard, w

memory strips once or in a different slot, or replace the new memory strips. If there is a problem with the memory bar, the computer will have a continuous "beep" sound when it starts. The beep is different because the motherboard is different. 7. Check CPU and motherboard CPU block contact is good? Due to moving or other factors, so that the CPU and SLOT1 socket or SOCKE370 socket bad contact. It is best to press the CPU by hand or remove the CPU and reinstall it again. 8. Check the CPU FSB,

look at the PCB screen printing, if it is not found, you can search the master chip pin definition diagram to find Earse and TST. wipe Flash with a USB cable to connect the PC, if there are j-link firmware, the board LED will be lit. Use jumper caps to shorten the Earse two pin, and if you do not have a soldering pin, you can use tweezers or wire to short connect. After the LED is off, unplug the jumper ca

Checksum error-defaults Loaded", that is to prompt you "CMOS in the inspection of the error, has loaded the system default value" BIOS password cracked successfully. The third trick: jumper short Connection If the motherboard CMOS chip and the battery is integrated in a piece, or the battery is directly welded to die on the motherboard, there is the second way we use the "CMOS discharge method", the results do not work, then we will use

clear the password. Open the main enclosure cover and locate the CMOS jumper on the motherboard. The jumper has 3 pins and is identified next to the jumper. Jumper caps are inserted on 1, 2 pins when normal. To the computer discharge, the CMOS discharge jumper cap from 1,

performance, while a photoelectric conversion device is cheaper. Therefore, the device to be used should be determined based on the network's data transmission needs and investment quotas. Note that not all optical fiber transceiver supports full duplex, and some products only support half duplex. Therefore, you should pay attention to identification during the purchase. In addition, considering compatibility, we recommend that you use products of the same brand and type. One end of the optical

Today, people need to process, store, and connect more data in a smaller area. The best way that everyone can think of is to make good use of each rack unit and make full use of its potential. This situation also applies to passive connection products. How to plan the capacity, growth, space and power supply of the data center, and how to achieve high stability and reliability in a high-density environment requires meticulous work. Requirement: ensures secure and reliable information transmissio

The system BIOS does not correctly recognize the IDE hard disk. If the system BIOS does not correctly identify the IDE hard disk, check whether all hardware devices, disks, data lines, or motherboard are working properly. 1. If a controller works properly on another motherboard, connect the hard disk to the Controller and check whether the hard disk can be identified in the BIOS. 2. Re-unplug the hard disk data and power connections. If possible, try other data and power cables. 3. Check the

Select one based on your needs. Hope to help you. Intelligent Management of smart cabling systems mainly involves information recording and updating, error identification, configuration changes, and error alarms. Specifically, automatically detects and discovers cabling ports, automatically detects connections between ports, understands port statuses, records jumper Connection events, manages remote smart cabling systems in real time, and determines w

We often see 0 euro resistance in the circuit. For new users, it is often confusing: since it is a 0 euro resistance, it is a wire, why should we install it? Is there such a resistance market available? In fact, 0 euro resistance is quite useful. The following functions are available:① Used as jumper. This is both beautiful and easy to install.② In digital and analog hybrid circuits, it is often necessary to separate the two and single point connectio

When dealing with computer networks, it is inevitable that network cables should be used frequently. In fact, the production of Network cables is very simple, that is, to insert the 4-to-8-Core Cable of twisted pair wires into the crystal head according to certain rules, therefore, the materials required for the production of such network cables only need twisted pair wires and crystal heads. The required tools are also relatively simple. Generally, only one dedicated crimping clamp is required.

step.Explanation: this is because the second, third, and fourth tests of the memory are not set to be skipped in the CMOs, and four memory tests are executed at startup. Of course, you can also Press ESC to end the memory check, however, this is too troublesome every time. You can select BIOS featurs setup after entering coms settings, set quick power on self test to enabled, and store and restart. 4. keyboard error or no keyboard presentChinese: the keyboard is incorrect or not connected.Expla

doubling, but modifying the frequency doubling improves the CPU performance as well as the external frequency. The external frequency speed is usually closely related to the speed of the front-end bus and memory. Therefore, when you increase the CPU external frequency, the performance of the CPU, system, and memory is also improved. There are two main ways to overclock the CPU:One is hardware settings, and the other is software settings. Hardware settings are commonly used, and they are divided

Hard drives with different SCSI specifications: With 68-pins Wide SCSI connectors, you can transfer data using the 16-bit channel width. With 60-pins narrow SCSI connectors, data can only be transmitted in a 8-bit channel width. Jimper (jumper) settings, mainly used to adjust the ID of the hard drive, terminal resistor switches and so on. SCSI hard drives are very ex
