Problems solved by technology
During the research and development stage, users often change the settings and configurations, so each time before using the motherboard, it is necessary to reconfirm whether the connection method of the setting jumper is correct, so as to avoid problems with the operation of the device due to mismatched settings and configurations However, in the R&D test, if different users operate, it is often impossible to determine whether the current jumper setting method conforms to the original setting, or the jumper is set incorrectly, resulting in the operation of the computer device or server device Exceptions also increase the difficulty of debugging
[0003]
On the other hand, during the R&D test, the central processing unit on the main board may also be replaced due to the needs of different users, and therefore there is often a problem that the central processing unit and the socket on the main board are loose.
Especially in some cases, it may be that the central processing unit is installed improperly or skewed, and only some pins are not connected to the slots on the motherboard, which makes a small number of functions invalid. In some cases, it is not easy to find faults. problem, but still distort test results
In addition, if there is an error in the operation of the central processing unit, it may also cause serious damage to the system

Embodiment Construction
[0014] see figure 1 As shown, the present invention provides a method for detecting the connection status of motherboard components. A motherboard 100 includes a micro-processing unit 110, a central processing unit slot 120, jumpers J1, J2, . . . , Jn, and light-emitting units LED1, LED2, ..., LEDn. In this embodiment, the microprocessing unit 110 can be a complex programmable logic device (CPLD) on the motherboard 100 to control the power-on procedure, and the central processing unit slot 120 is used to set the central processing unit 200, and across The connectors J1, J2, . . . , Jn are used to provide setting voltage levels V1, V2, . It should be understood that the set voltage levels V1, V2, . , the types, quantities, and pins of the connected components may also be different. The light emitting units L1, L2, . . . , Ln are arranged beside the jumpers J1, J2, .
[0015] In this embodiment, the memory unit 112 of the micro-processing unit 110 stores a preset set value g...

A method for detecting the connection state of mainboard elements is suitable for a mainboard with a micro-processing unit and at least one jumper, wherein the set voltage of the jumper is used for determining at least one set configuration of the mainboard, and a preset voltage level is pre-stored in a memory unit of the micro-processing unit. The method for detecting the connection state of mainboard elements comprises the following steps: arranging a light-emitting unit beside each jumper; judging whether the set voltage level of each jumper accords with a corresponding preset voltage levelor not; and if the set voltage level of the jumper does not accord with the corresponding preset voltage level, controlling the corresponding light-emitting unit to emit light in a specific mode to warn a user. In addition, when the central processing unit is installed incorrectly, an alarm is given out.
Description
technical field [0001] The invention relates to a method for detecting the connection status of mainboard components, in particular to a method for detecting whether a jumper on the mainboard and a central processing unit are correctly connected to the mainboard. Background technique [0002] At present, the motherboards on computer devices or server devices usually have some jumpers. During the research and development stage, users can adjust the connection method of the jumpers to change the settings related to the motherboard (for example, clear CMOS, network port settings, VGA activation or other specific functions of the motherboard, etc.), to meet the current operating mode of the user, and with the different specifications of the motherboard, the number of jumpers and the corresponding functions of the settings also vary. may be different. Generally speaking, a jumper selectively connects a node to a high voltage level or a low voltage level through its connection me...
