Abstract

The present invention relates to an error detection display method for electronic components of data processing systems. Once a data processing system is powered on, the basic input-output system (BIOS) will start testing the data processing system, especially before the screen display of the monitor of the data processing system. If an error is found on any dynamic random access memory (DRAM), BIOS, or video graphics access (VGA) card, the light emitting diodes (LED) for power indication equipped on the case of the host of the data processing system will start flashing in various frequencies to indicate fault or improper installation of the components.

H The source diode 1 was recorded on the outside of the host of the lean material processing system. The forward diode (LED) flickered at different frequencies, indicating that the above items were damaged or the device was incorrect. Methods. N Background of the Invention In the architecture of the data processing system, the so-called basic input-output system (BI0s) is the first program to be executed after the data processing system, which guards the first system for the entire system. If this is not possible, completing the BIOS program usually means that some hardware may be defective. Whenever we turn on the data processing system, the central processing unit (cpu) automatically executes a series of instructions. These instructions are divided into: (a) System Configuration Analysis • Analysis of CPU model and memory size , The number and type of hard disk drives, whether to install floating-point arithmetic units, etc., as important reference materials for subsequent actions. (2) Power-on Self Test (POST): Tests hardware such as memory, chipset, CMOS storage data, keyboard, and drive.

The input and output system (bios) device test system is as follows: first, dynamic random access memory (DRAM), the basic input and output system (BI0s) device itself, the display (VGA) card, and then other peripheral devices to detect ... | ★ If an error occurs before the video card is detected, it cannot be known from the monitor (monitor) that the B 10S itself, the dynamic random pure memory, and the video card have any errors. The user must use the data processing system The casing is opened and confirmed. Even if it is sent to the maintenance department, if it is impossible to know in advance which parts are faulty or the device is wrong, it must take time to test one by one, causing user confusion, and increasing the maintenance time of the maintenance staff. In solving the above-mentioned detection problems, I know a good way to do it. 鑀 {£ No, it is based on the test machine accesses the memory BIOS 1 and the display (VGA) card 3 after the computer is turned on one by one. 告, 卞], For the above, an error brick + is transmitted through the south bridge chip 4 in the system chipset to the elephant speaker, and (speaker) 5 emits beeps of different frequencies f, indicating that the dagger has an error, but in fact it is not used. The speaker does not allow "sound resolution": different. You two know: Method one, as shown in Figure two, is attached to the ㈣m machine board, install light-emitting diodes of different colors (15, κ ,, Yu After booting up, the disk test machine accesses the memory one by one (DRAMM2, basic output = system device (RT0S) 1), and displays 0 to 1. Card 13 When the above components issue a system error, they are captured by the system chipset. Nanxun Jingyue 14 was transmitted to the main board. No-cabinet color, light-emitting diodes, 1 &, m, show different: the correct I pieces are wrong, but the method of this conventional technology must increase the emitter , Increased manufacturing and Chengtai, 1 due to installation on the motherboard, only; 5 12275 V. Description of the invention (3) The test in the production test stage 'After the data processing system is assembled and delivered to the consumer, the consumer must still disassemble the housing of the data processing system to be able to-to-learn techniques What is the jitter? Yuan ♦ ^ It is the reason for my post.

Summary of the Invention This case also provides two types of cases without the need to add an additional light-emitting two-body body, as well as the user and the maintenance of the stripe or testing arts without the need to disassemble the housing of the system. Next, after the monitor is turned on, before the monitor displays the screen, the light-emitting diodes located on the housing of the data processing system flash at different frequencies to display the errors that occurred during the basic input-output system test at this stage. According to the idea of this case, it is to provide a Electronic method, the computer shell is equipped with the DEL key.) The test result of the polar body placement test indicates that the moving wheel is delivered to the second electronic unit # It is located in a data processing system (desktop computer or note or server). The data processing system has a host. The host is equipped with a light-emitting diode. When the data processing system is turned on (including a warm boot (simultaneously press 2CTRL key, ALT key on the computer keyboard, or press the reset key of the host computer), set the power supply to the initial state of the light to the full light state, the basic wheel into the wheel is also like a line ^ The first electronic component ( (Such as dynamic random access memory), for example, if the error (in the case of dynamic random access memory is not the correct, state random access memory specification model), the basic round-robin system device transmits the first signal to Once the reef is set, the reef is installed next to the light-emitting diode so that the light-emitting diode flashes at the first frequency.

If Shuo can correctly determine the specifications of the remote dynamic random access memory, check whether the second type of electronic components (such as the basic input / output system device) is incorrect. Check the result-for the error (the basic input / output) The system device is a program in the basic input-output system device. When checking the checksum value of the basic input-output system device, the third signal is transmitted to the 忒 decoding device, and the decoding device transmits the fourth signal to The light-emitting diode flashes at the first frequency, if the check result is correct (in the case of a basic input-output system device, it is a program in the basic input-output system device, and the checksum value of the basic input-output system device is correct) When the second > electrical sub-component (such as a graphics card) is wrong, if the detection result is an error (in the case of a display card, it is impossible to correctly determine the specification model of the display (VGA) card) ^ , The third signal is transmitted to the decoding device, and the decoding device transmits the fourth signal to the _. The light-emitting diode flashes at the third frequency. If the good result is correct (display When the card is correctly judged in terms of the VGA card gauge eligible models), then continue with other basic input output system testing. ^ As long as it is not a CPU error and the BIOS executes the self-test part of the program, =, = I performs the BIOS self-test procedure; if the CPU error or BI0s failure occurs (the self-test cannot be performed), the initial setting of the power LED is 2 On, if there is a p-month condition when the power LED is fully on and the monitor has no picture after powering on, it can be seen that the CPU error or M0s is completely damaged. As for shame, BI 0S and VGA errors, you can learn from this creation based on the blinking frequency of the power LED: ， ΓίΓί: 'After the test is completed, the electronic components can be informed by the monitor.

The third and fifth signals passed are command signals. , Σ describes the first and the number. The first, fourth, and sixth signals are hardware signals. The flashing frequency of the light-emitting diodes can be a single time, followed by continuous lighting for 3 seconds and off for 3 seconds. Lian and Ge redundant 1 second off 1 second 2 The difference between the above Ϊ is judged by the naked eye, so the difference between the two is the same as: u ^ single-frequency is not the same day, the inner eye ρ π a \ mother The number of flashes in the second is more than 20 times, and the number of flashes is more than 20. Therefore, the above-mentioned flashing frequency is based on the number of flashings per second.
