POST power on the test: Almost all hardware for the system is detected. How is POST for self testing? The main board is connected to the power supply, the system first by On Self Test Power, on the power of the test Seanix KM266-D1 Chipset check the internal devices. When the power supply stable power supply of course from unstable to stable process is only momentarilychipset and removed reset signal if it is manually pressing the reset button on the panel of the computer to restart the machine, then release the button when the chip set will be removed from the reset signal, the CPU immediately on from the address FFFF0H began execution instructions and the address in the system BIOS address range, whether it is award BIOS or AMI BIOS, put in here just a jump instruction, jump to the system BIOS boot code in the real office.

System BIOS start code first thing to do is to carry out POST On Self Test Power, plus electric self-testdue to the computer's hardware devices including memory, interrupt, expansion cardso to detect the work of these devices is normal.

Git - - share/misc/pci_vendors

If a device does not pass the test, then the CODE POST will be retained in the 80H, the test program will be suspended, and according to the alarm sound of the alarm BIOS vendors are also defined for the alarm, the alarm sound is different, we can according to Seanix KM266-D1 Chipset alarm sound, the fault location. What is the order of the POST self-test?


Detection of the previous process of graphics card said key parts testing, if the key parts of the problem, the computer will be in a state of suspension, known as the core failure. In normal circumstances, the POST process is very fast, and we can hardly feel this process. What is the meaning Seanix KM266-D1 Chipset POST self testing code? When the system detects the error, it will be reported in two ways, that is, the error message is displayed on the screen or the number of times of the alarm sound.


This is usually because of the lack of battery power, so you might as well Seanix KM266-D1 Chipset to change the battery to try. Switch is set incorrectly Display display switch configuration error. Please wait for a moment.

But on the old hard drive, its start is slower, so will appear this problem. Slave hard fail Secondary detected from disk failure. Disk diagnosis s fail Hard hard disk diagnostics. You can put the hard disk to Seanix KM266-D1 Chipset computer to try, if the problem is the same, then had to repair the.

Power cable is not good? If it's all right, buy a new one. Keyboard Seanix KM266-D1 Chipset or no keyboard present keyboard error or no keyboard Reason: Is the connecting line damaged? Test fail Memory memory test failure Reason: But on the old hard drive, the action is slow, so you'll see the message.

POST - number of rings is how to define? POST on the electric self-test will be the number of times through the alarm sound to detect the Seanix KM266-D1 Chipset. POST how to indicate the error after the discovery? POST self check if there is a mistake, will be in two cases: If we press the power button, only the power indicator light, the computer screen is not any reflection, nor the sound of the alarm; so for this situation, we should be how to solve it? The screen did not show, nor the sound of the alarm, we can not get the appropriate information from the POST self-test function; we all know that the computer is a complex and sophisticated product mix, Seanix KM266-D1 Chipset a link problems, may not start the machine we mainly talk about hard parts. Therefore, such as the emergence of a black screen, no alarm sound fault phenomenon, we should according to the computer's startup process to analyze the problem.

What is the starting process of the computer? When we press the start button, the first to start the power supply because if there is no power supply, then all the main components are unable to work. But in order to ensure the safe use of power supply part of a series of safety protection measures; so the switching power supply from the vibration to the stability of a period of delay, wait for each part of the voltage is stable, the power supply of a detection signal, the signal is high power usually said that part of the normal voltage, these parts, including the input voltage and output voltage.

Actually board Seanix KM266-D1 Chipset this time, but also according to the defined combination of CPU VID0VID3 pin, the CPU provided VID0VID3 signals sent to the corresponding port of the power management module; if the motherboard BIOS can set the CPU voltage function, the motherboard will in time set voltage and vid corresponding relations new vid signal is generated and sent to the power management chip module, power management module will according to the set and through the DAC voltage will be converted to voltage reference, through the field effect pipe rotating guide pass on and off, energy through the inductance coil is delivered to a CPU.

Finally, after regulating circuit and the output voltage and the voltage setting value. Because CPU also need to be based on the frequency of their own, through the IC bus to detect the frequency generator set up the frequency of support; because the computer to carry out the correct data transmission and normal operation, no clock signal is not good, the main role of the clock signal in the circuit Seanix KM266-D1 Chipset synchronized, because in the process of data transmission, the timing has strict requirements, only in order to ensure that the data in the transmission process is not error. The clock signal is first set a benchmark, we can use it to determine the width of the other signal, the other clock signal to ensure the synchronization between the Seanix KM266-D1 Chipset and receiving data.

For CPU, the clock signal as a benchmark, CPU internal signal processing to it as a yardstick, so it determines the speed of execution of the Seanix KM266-D1 Chipset command; if the CPU itself is not able to adapt to the frequency of the frequency generator provided by the high frequency, but also can not work. How to judge and solve the problem? Because if you do not accept the GOOD POWER signal, the system has been processing RESET reset cycle, so the motherboard can not be started, the corresponding other hardware, such as graphics can not work, because the display is not receiving the video signal, so it is not shown, a straight in standby mode. At this point, we should detect power, do not assume that the power light, it is normal, because as long as there is a signal of the fault the part of the circuit is not normal or not stablethe input GOOD POWER signal is low, which means that the power supply is still not in a stable state, although the power indicator light, but because the motherboard is not normal GOOD POWER signal, it can not start.

We detect the power of the method is to use the normal work Seanix KM266-D1 Chipset the power test.

Such as power supply for the ATX type we can use the wire will be 13 and 14 pin short, such as the power supply fan can run normally, it shows that the power is in good condition, the fault should be on the motherboard. Replacement of the normal power supply, imaging systems, such as a job or not, should according to the above board to start the process, test the CPU power management module, and a frequency generator. But because we can't have a sound device to test the power and frequency modules on the motherboard most computer enthusiasts can't have this kind of setup, and have the ability to detect. So we have to use the exclusion method, that is, the other normal on the motherboard CPU.

Testing to exclude the CPU fault, but also to detect the motherboard frequency settings. To adjust the working frequency of Seanix KM266-D1 Chipset CPU.
