BIOS is the primary information reading direction when the IPC is started, if it is not set properly, the IPC will not be able to boot normally. When the IPC fails to start normally, it can complete the repair of unknown faults by restoring the BIOS factory settings. So how to restore the factory settings of the industrial motherboard BIOS?
1. Enter the main interface of BIOS settings to operate, the process is as follows:
1. Press the Delete button to enter the BIOS setting interface.
2. Select "Load Setup Defaults" under the "Exit" menu and press Enter, select "Yes", and press Enter again.
3. Press the "F10" button, select "Yes" and press Enter, the system will restart at this moment, and the BIOS will be successfully restored to factory settings.
2. Discharge operation on the industrial motherboard in the following ways:
1. Use CMOS discharge jumpers
At present, most industrial motherboards are planned with CMOS discharge jumpers to facilitate the discharge operation of users, which is the most commonly used CMOS discharge method. The discharge jumper is usually a three-pin and is located near the CMOS battery socket of the industrial motherboard, and is accompanied by a battery discharge statement. With the tacit consent of the industrial motherboard, the jumper cap is attached to the pins marked "1" and "2", and it can be known from the discharge clarification that it is "Normal", that is, the normal usage condition.
To use this jumper to discharge, first pull the jumper cap from the pins "1" and "2" with tweezers or something else, and then attach them to the pins identified as "2" and "3", and the discharge clarifies that the condition is "Clear CMOS", that is, the CMOS is removed. After a short period of contact, the user's various manual settings in the BIOS can be erased and the default settings of the industrial motherboard can be restored to the factory default.
After discharging the CMOS, the jumper cap needs to be removed from the "2" and "3" pins, and then rehabilitated to the original "1" and "2" pins. Note that if the jumper cap is not restored to normal condition, the IPC will not be able to be started and there will be an alarm sound.
2. Take out the CMOS battery
Find the CMOS battery socket on the industrial motherboard, and then press the clip on the socket to hold the power supply battery to the side, and the CMOS battery will actively pop out at this moment, and take out the battery carefully. Then start the IPC, and the screen will prompt that the data in the BIOS has been erased, and you need to enter the BIOS to set it from scratch.
3. Short the positive and negative poles of the battery socket
The CMOS battery socket is divided into positive and negative poles, and they can be shorted to achieve the discharge intention.

The causes and solutions of EVOC industrial computer crash
1. The industrial computer "crashes" due to hardware reasons
Reason analysis: When the industrial computer processes too many on-site signals transmitted by the PLC, the CPU frequency of the industrial computer is low, and the memory is small, so it is impossible to identify and process so many signals together, so that these signals "crash" and form an industrial ...

The difference between parallel port and serial port of industrial computer
Parallel interface, referred to as parallel port. The parallel port of the industrial computer uses a 25-pin D-connector. The so-called "parallel" means that 8-bit data is transmitted together through parallel lines, so that the data transmission speed is greatly improved, but the length of the parallel transmission line is limited, and due to the increase in length, the disturbance will increase.
