Motherboard detection method

The present invention relates to a detection method, in particular to a motherboard detection method for detecting whether a processor installed on a motherboard is improperly installed.

During the epidemic, in order to avoid the risk of the spread of the epidemic, various companies will control the flow of people by reducing the flow of people. As a result, when the factory is mass-producing motherboards, technicians may not be able to go to the site to observe the production status. When a problem occurs when the motherboard is turned on, one can only rely on the production staff's oral complaints, photos, videos, or log files (logs) generated by the BIOS (Basic Input/Output System) to initially determine the cause of the error, and debugging is often time-consuming. Count hours or even days.

One of the common types of errors is that the production end may not be able to tell what type of processor the CPU to be installed is, and the compatibility between processors and between the processor and the motherboard is not properly considered. After the computer was installed, it was discovered that the computer could not be booted. At this time, the technician needed to spend time and energy to find the cause of the error from lengthy videos and logs. Therefore, it was necessary to come up with a solution to quickly identify the problem due to the compatibility of the processor. The cause of the error that causes the computer to fail to boot.

Therefore, the purpose of the present invention is to provide a motherboard detection method that can quickly identify whether the processor installed on the motherboard cannot be started normally due to improper installation.

Therefore, a motherboard detection method of the present invention is implemented by a complex programmable logic device installed on a motherboard. The motherboard is also equipped with at least one central processing unit and a circuit electrically connected to the complex programmable logic device. A light unit connected to the complex programmable logic device and including at least one pair of indicator lights corresponding to at least one central processing unit, the motherboard detection method includes a step (A), a step (B), and a step (C) , one step (D), and one step (E).

In step (A), the complex programmable logic device obtains compatibility information indicating whether the motherboard is designed to allow the installation of a CPU that supports high-bandwidth memory.

In step (B), the complex programmable logic device determines whether the motherboard is designed to allow the installation of a central processor that supports high-bandwidth memory based on the compatibility information.

This step (C) is when the complex programmable logic device determines that the design of the motherboard does not allow the installation of a central processor that supports high-bandwidth memory. For each central processor, the complex programmable logic device starts from the central processor. The processor obtains type information indicating that the CPU is one of a high-bandwidth CPU that supports high-bandwidth memory and a general-type CPU that does not support high-bandwidth memory.

The step (D) is for the complex programmable logic device to determine whether there is at least one high-bandwidth CPU in the at least one CPU based on the at least one type of information.

The step (E) is when the complex programmable logic device determines that the at least one high-bandwidth central processor exists, the complex programmable logic device controls the on and off of the at least one indicator light according to the obtained type information, where the corresponding The indicator light of the high-bandwidth type CPU turns on and off in a first way, while the indicator light corresponding to the general type CPU turns on and off in a second way that is different from the first way.

The function of the present invention is to obtain the compatibility information through the complex programmable logic device, and determine whether the motherboard is designed to allow the installation of a central processor that supports high-bandwidth memory. When it is determined that it does not support it, it is determined that the motherboard is not supported. Whether the at least one high-bandwidth central processing unit exists in at least one central processing unit, and when it is determined that it exists, control the on and off of the at least one indicator light to quickly identify incompatible central processing units based on the on and off of the at least one indicator light. The processor can be used to quickly identify whether the processor installed on the motherboard is improperly installed.

Before the present invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

Referring to Figure 1, an embodiment of the motherboard detection method of the present invention is implemented by a motherboard 1. The motherboard 1 is equipped with a complex programmable logic device 11 (Complex Programmable Logic Device, CPLD for short), at least one electrical coupling The central processing unit 12 (Central Processing Unit, CPU for short) of the complex programmable logic device 11, a light electrically coupled to the complex programmable logic device 11 and including at least one pair of indicator lights 141 corresponding to at least one central processing unit 12 unit 14, and a circuit module 13 electrically coupled to the complex programmable logic device 11. In this embodiment, each CPU 12 includes a type output module 121 for outputting a type of information. The type information indicates that the type of the corresponding CPU is one that supports High Bandwidth Memory. A high-bandwidth central processor (HBM for short) or a general-purpose central processor that does not support high-bandwidth memory. The central processor 12 may be a server processor (Sapphire Rapids) produced by Intel Semiconductor Manufacturing Company. SPR). In this embodiment, each type of output module of each central processor 12 includes three pins (pin BN64; AY63; BL64), but it is not limited to this; it can also be four pins or two pins. Pins, etc., depending on the number of categories of a series of central processors 12, the number of pins included in the output module 121 of each type of central processor 12 may also be different, and the corresponding electrical coupling method may also be specified in the output connector. Pins plus pull-up resistors (not shown) are not limited to this. For example, each type of information indicates the package type identification code (Package ID) of the corresponding central processor 12, and the package type identification code indicates the package type (Package Type) of the corresponding central processor 12, for example: Pin grid array package (Ceramic Pin Grid Array Package, PGA package), ball grid array package (Ball Grid Array Package, BGA package) or plastic flat package (Plastic Flat Package, PFP package), etc., are not regarded as Limitation, in this embodiment, the packaging form of the general-type central processing unit is different from the packaging form of the high-bandwidth type central processing unit. That is to say, the general-type central processing unit and the high-bandwidth type central processing unit respectively correspond to different Package type identification code (that is, type information), therefore, the general CPU and the high-bandwidth CPU can be generated by the three potential pins corresponding to each CPU 12 type information to distinguish.

It is worthy of special explanation that when the voltage logic levels output by the three pins of the type output module 121 of one of the at least one central processor 12 together form a voltage logic level such as 000 (also That is, when this type of information), it means that the corresponding CPU 12 is a general-type CPU that does not support high-bandwidth memory, wherein the general-type CPU is a central processing unit designed to operate with non-high-bandwidth memory. That is to say, when the general CPU (the CPU that does not support high-bandwidth memory) is used to boot or operate with high-bandwidth memory, the general-type CPU cannot make better use of the high bandwidth. Memory, for example, cannot transmit data with the high-bandwidth memory at the highest bandwidth allowed by the high-bandwidth memory, because the data transmission speed between the general CPU and the high-bandwidth memory cannot reach the high-bandwidth memory. The faster data transmission speed that the body can provide; when the voltage logic levels output by the three pins of the central processor 12 together form, for example, 010, it represents the corresponding central processor 12 In order to support the high-bandwidth CPU of high-bandwidth memory, the high-bandwidth CPU is designed to be a CPU that can operate with high-bandwidth memory. That is to say, when using the high-bandwidth CPU (supporting high-bandwidth memory) When the body's CPU) is booted or operated with non-high-bandwidth memory, the high-bandwidth CPU (the CPU that supports high-bandwidth memory) may generate a transmission error message and fail to complete the boot initialization process. It can even cause memory or system damage. The circuit module 13 electrically coupled to the complex programmable logic device 11 is used to output a compatibility information, the compatibility information indicates whether the motherboard is designed to allow the installation of a central processor that supports high-bandwidth memory, In other words, whether the motherboard 1 allows the installation of the high-bandwidth central processing unit (a central processing unit that supports high-bandwidth memory). For example, the circuit module 13 electrically coupled to the complex programmable logic device 11 is used to indicate the project identification code (Project ID) of the motherboard in the development stage. Motherboards with different project identification codes have central processing units installed thereon. The CPU models/types may be different, and if the CPU models on the two motherboards are the same but correspond to different project identification codes, it means that the CPUs on the two motherboards execute the Basic Input and Output Systems respectively. /Output System, BIOS) firmware programs are different. The circuit module 13 is a circuit composed of at least one of a pull-up resistor and a pull-down resistor, and the circuit module 13 includes three potential pins. The three potential pins are respectively The output voltage levels together form a category identification code related to the motherboard system, such as a project identification code or a product identification code (Product ID), as the compatibility information. That is to say, the compatibility information has different The motherboards corresponding to the information also have different hardware configurations. That is, motherboards with different compatibility information may be equipped with different types of central processors 12 . In this embodiment, when the three potential pins output, such as 001, 011, 101, and 111, it means that the motherboard is designed to allow the installation of a high-bandwidth central processor that supports high-bandwidth memory, and the motherboard can also be installed. General CPU; when these three potential pins output, such as, 000, it means that the motherboard is designed not to allow the installation of high-bandwidth CPUs that support high-bandwidth memory (that is, it only allows the installation of high-bandwidth CPUs that do not support high-bandwidth memory). General CPU with memory).

Referring to Figures 1 and 2, an embodiment of the motherboard detection method of the present invention includes steps 601 to 611.

In step 601, the complex programmable logic device 11 obtains the compatibility information based on the outputs of the potential pins.

In step 602 , the complex programmable logic device 11 determines whether the design of the motherboard 1 allows the installation of a CPU 12 that supports high-bandwidth memory based on the compatibility information obtained from the circuit module 13 , that is, , the complex programmable logic device 11 determines based on the compatibility information whether the motherboard 1 is designed to allow the installation of the high-bandwidth central processor that supports high-bandwidth memory, or is designed not to allow the installation of the high-bandwidth central processor, and Only general-purpose CPUs that do not support high-bandwidth memory can be installed. When the complex programmable logic device 11 determines that the design of the motherboard 1 does not allow the installation of the high-bandwidth CPU, it means that the motherboard 1 is designed to only install the general CPU that does not support high-bandwidth memory. , then the process proceeds to step 603; when the complex programmable logic device 11 determines that the motherboard 1 is designed to allow the installation of the high-bandwidth CPU, it means that the motherboard 1 allows the installation of the high-bandwidth CPU that only supports high-bandwidth memory. processor, or allows only the installation of the general CPU that does not support high-bandwidth memory. When the motherboard 1 is designed to allow the installation of the high-bandwidth CPU, compared with the installation of only the high-bandwidth CPU Compared with the operating performance of the motherboard that only installs the general central processor, the motherboard that only installs the high-bandwidth central processor can use a higher bandwidth to electrically couple with the high-bandwidth central processor 12 provided on the motherboard. The memory transfers data to achieve better operating performance, and the process proceeds to step 607.

In step 603, for each CPU 12, the complex programmable logic device 11 obtains an indication from the CPU 12 that the CPU 12 is a high-bandwidth CPU or a general CPU. information of this type.

In step 604, the complex programmable logic device 11 determines whether there is at least one high-bandwidth CPU in the at least one CPU 12 based on the at least one type information. When the complex programmable logic device 11 determines that the at least one high-bandwidth central processor exists, it means that the at least one high-bandwidth central processor is an incorrectly installed central processor 12, and the process proceeds to step 605; when the complex programmable logic device 11 When it is determined that the at least one high-bandwidth central processor does not exist, it means that all the central processors 12 on the motherboard 1 are correctly installed central processors 12 (general central processors), and the process proceeds to step 606. For example, if the number of the at least one CPU 12 is 4, and among the corresponding 4 types of information, one of the types of information indicates that the corresponding CPU 12 is a high-bandwidth CPU. When , it is determined that the four central processors 12 are mixed (that is, three central processors 12 are general central processors, and one central processor 12 is a high-bandwidth central processor). Step 605 will then be performed.

In step 605, the complex programmable logic device 11 controls the at least one indicator light 141 to turn on and off according to the at least one type of information, wherein the indicator light 141 corresponding to the high-bandwidth central processor turns on and off in a first manner, and the corresponding indicator light 141 turns on and off in a first manner. In a general CPU, the indicator light 141 turns on and off in a second manner that is different from the first manner. That is to say, the complex programmable logic device 11 controls the indicator light 141 corresponding to each general CPU to turn on and off in a second manner, such as a constant light or constant dark mode without flashing, and controls each high-bandwidth The indicator light 141 corresponding to the type of central processing unit flashes at the first frequency of the first mode, for example, at a frequency of 2 Hertz (Hz), or may flash at a frequency of 3Hz, 4Hz, etc., but is not limited to this. This is to assist the user to quickly distinguish between a correctly installed general CPU and an incorrectly installed high-bandwidth CPU, but is not limited to this. Through this, it is possible to know which CPU 12 in the motherboard 1 is an incorrectly installed CPU mixed with a high-bandwidth CPU under the premise that the motherboard 1 does not support a high-bandwidth CPU. 12.

In step 606, the complex programmable logic device 11 performs a power-on sequence related to the motherboard 1 and corresponding to the at least one general CPU. At this time, the complex programmable logic device 11 performs a power-on sequence corresponding to the The firmware and setting parameters of the general CPU are used to activate/deactivate the corresponding functions and continue the boot process accordingly. It is worth mentioning that the complex programmable logic device 11 in addition to performing the at least one general CPU The electrical sequence also simultaneously controls the indicator light 141 corresponding to the general CPU to turn on and off in a second manner, such as a constant light or a constant dark mode without flashing, but is not limited to this.

In step 607, for each CPU 12, the complex programmable logic device 11 obtains an indication from the CPU 12 that the CPU 12 is one of the high-bandwidth CPU and the general CPU. information of this type.

In step 608, the complex programmable logic device 11 determines whether there is at least one high-bandwidth CPU in the at least one CPU based on the at least one type information. When the complex programmable logic device 11 determines that the at least one high-bandwidth central processor does not exist, it means that the motherboard 1 is designed to only allow the installation of the at least one general-purpose central processor, and all the processors on the motherboard 1 The central processors 12 are all correctly installed central processors 12 (general central processors), and the process proceeds to step 606; when the complex programmable logic device 11 determines that there is at least one high-bandwidth central processor, it represents the The motherboard 1 is designed to only allow the installation of at least one high-bandwidth central processing unit, and the possible situation is that all the central processing units 12 on the motherboard 1 are correctly installed central processing units 12 (high-bandwidth central processing units). ), or if all the CPUs 12 on the motherboard 1 have a mixture of high-bandwidth CPUs and general CPUs, the process proceeds to step 609.

In step 609, the complex programmable logic device 11 determines whether there is at least one general-type CPU in the at least one CPU 12 based on the at least one type information. In the case where the motherboard 1 is designed to only allow the installation of the at least one high-bandwidth central processing unit, when the complex programmable logic device 11 determines that the at least one general type central processing unit is present, it represents the at least one general type central processing unit. The CPU 12 is the wrongly installed one, and the process proceeds to step 610; when the complex programmable logic device 11 determines that there is no at least one general CPU, it represents all the CPUs on the motherboard 1. The processor 12 is a correctly installed central processing unit 12 (high-bandwidth central processing unit), and the process proceeds to step 611.

In step 610, the complex programmable logic device 11 controls the at least one indicator light 141 to turn on and off according to the at least one type of information, wherein the indicator light 141 corresponding to the high-bandwidth central processor turns on and off in the first manner, and the corresponding indicator light 141 turns on and off in the first manner. In a general CPU, the indicator light 141 turns on and off in a third way that is different from the first way and the second way. Since the at least one high-bandwidth CPU can make the motherboard 1 operate better, the complex programmable logic device 11 controls the indicator light 141 corresponding to each high-bandwidth CPU in the first manner. A frequency, for example, flashes at a frequency of 2 Hertz (Hz), or may flash at a frequency of 3Hz, 4Hz, etc., but is not limited thereto, and controls the indicator light 141 corresponding to each general-type central processing unit to operate in different ways. Flashing in the third mode of the first frequency and the second frequency, but is not limited to this. From this, it can be known that the motherboard 1 supports a high-bandwidth central processor according to the flashing of the indicator light 141 Depending on the frequency, it is known which of the CPUs 12 of the motherboard 1 is a high-bandwidth CPU and which one is a mixed general-type CPU.

Furthermore, during the booting process of the motherboard 1, if the motherboard 1 mixes a general CPU and a high-bandwidth CPU, the motherboard 1 will not be able to boot smoothly (that is, some (the central processing unit 12 cannot be initialized). At this time, through the motherboard detection method of the present invention, it is possible to quickly identify whether a mixed use situation occurs based on the flashing state of the indicator light 141 corresponding to each central processing unit 12, and to clearly identify whether a mixed use situation occurs. To find out the location/number of the central processing unit 12, for example, the corresponding indicator lights 141 are arranged in sequence according to the number corresponding to each central processor 12. Thus, the corresponding indicator light 141 can be found based on the flashing state of the corresponding indicator light 141. The central processing unit 12 further obtains the corresponding installation position according to the number of the central processing unit 12 .

In step 611, the complex programmable logic device 11 performs a power-on sequence related to the motherboard 1 and corresponding to the at least one high-bandwidth central processing unit. At this time, the complex programmable logic device 11 performs a power-on sequence corresponding to the The firmware and setting parameters of the high-bandwidth central processor are used to enable/disable corresponding functions and continue the boot process accordingly. In other words, because all the central processors 12 on the motherboard 1 are correctly installed central processors 12 (high-bandwidth central processing unit), so the complex programmable logic device 11 can perform a power-on sequence related to the motherboard 1 and corresponding to the at least one high-bandwidth central processing unit. It is worth mentioning that the complex programmable logic device 11 In addition to performing the power-on sequence of the at least one high-bandwidth CPU, the logic device 11 also simultaneously controls the indicator light 141 corresponding to the high-bandwidth CPU to turn on and off in a second manner, such as a constant light or constant dark mode without flashing. , but not limited to this.

To sum up, the motherboard detection method of the present invention obtains the compatibility information through the complex programmable logic device 11 to determine whether the design of the motherboard 1 is allowed to support high-bandwidth memory based on the compatibility data. CPU 12, and obtains the type information of all CPUs 12 to determine whether there is at least one high-bandwidth CPU in all CPUs 12. The design of the motherboard 1 does not allow installation to support high bandwidth. Under the premise that the central processor 12 of the memory is located, when it is determined that the at least one high-bandwidth central processor exists in all the central processors 12, the at least one high-bandwidth central processor is controlled according to the at least one type of information. The indicator light 141 turns on and off in the first manner, and the indicator light 141 corresponding to the general central processing unit is controlled to turn on and off in the second manner, whereby the motherboard 1 is designed to not allow the installation of a high-bandwidth central processing unit. Under the premise of using a high-bandwidth CPU, you can quickly know which CPU 12 in the motherboard 1 is mixed with a high-bandwidth CPU through the on and off status of the indicator light 141, thus causing the motherboard 1 to be unable to complete the boot process. In addition, Under the premise that the motherboard 1 is designed to allow the installation of a central processor 12 that supports high-bandwidth memory, when it is determined that the at least one high-bandwidth central processor exists in the at least one central processor 12, it will also continue to determine whether the at least one central processor 12 has a high-bandwidth memory. Whether the at least one general-type central processor exists in at least one central processor, so that when it is determined that the at least one general-type central processor exists, the at least one indicator light 141 is controlled to turn on and off according to the at least one type of information, thereby In order to know which CPU 12 in the motherboard 1 is a high-bandwidth CPU and which one is mixed with a general CPU, it can also quickly identify the motherboard 1 that cannot be started due to improper mixing. factors, so the purpose of the present invention can indeed be achieved.
