Fig. 1 is a block diagram illustrating an embodiment of a motherboard according to the present invention.
FIG. 2 is a flowchart illustrating an embodiment of the data loading method of the present invention.
[ detailed description ] embodiments
Referring to fig. 1, an embodiment of the motherboard of the present invention is suitable for a server, and includes a Field Replaceable Unit (FRU) 2 and a Baseboard Management Controller (BMC) 1.
The field replaceable unit 2 records a first product identifier 21 and a second product identifier 22 associated with the motherboard, where the first product identifier 21 is, for example, a product name (product name), and the second product identifier 22 is, for example, a motherboard identifier (board ID). The field replaceable unit 2 may be a non-volatile storage device such as a flash memory (flash memory) or other types of electrically erasable programmable read-only memory (EEPROM), and is electrically connected to the baseboard management controller 1 by a bus such as I2C (Inter-Integrated Circuit) or spi (serial Peripheral interface).
The baseboard management controller 1 supports the industry standard of Intelligent Platform Management Interface (IPMI), and is suitable for monitoring the operation status of the server, such as monitoring the temperature of the chassis, the rotation speed of the fan, the voltage status of the power supply, the temperature … of the motherboard, and so on. The baseboard management controller 1 includes a storage module 10, such as a Flash memory (Flash ROM), for storing a plurality of system image (image) data 11, 12 and a plurality of candidate image data 13, 14, and the baseboard management controller 1 determines which monitoring functions are enabled by loading one of the system image data 11, 12 and the candidate image data 13, 14 of the storage module 10. The multiple system image data 11, 12 are respectively related to the first product identifiers 21 of different motherboards, and the baseboard management controller 1 respectively executes different system monitoring functions according to the multiple system image data 11, 12, such as the system image data 11 is applied to the operation of the A motherboard and records monitoring items (sensor list) corresponding to the hardware design of the A motherboard, such as motherboard temperature, fan speed, CPU temperature, voltage supply status, the number of CPUs of the A motherboard, the number of dual in-line memory modules (dimm), the number of fans, etc., and the system image data 12 is applied to the operation of the B motherboard and corresponds to the monitoring items of the hardware design of the B motherboard, such as motherboard temperature, fan speed, CPU temperature, voltage supply status, etc., the number of CPUs of the B motherboard, The number of dual inline memory modules, the number of fans, etc. The multiple candidate image data 13, 14 may be different versions of at least one system image data 11, 12, for example, the candidate image data 13 is an updated version of the system image data 11, that is, for example, when a developer updates hardware of a motherboard to be an a 'motherboard, the candidate image data 13 can be used by the updated a' motherboard.
Referring to fig. 2, the data loading method of the present invention, executed on the motherboard of the server shown in fig. 1, includes the following steps.
In step a, the storage module 10 of the bmc 1 stores the system image data 11, 12 and the candidate image data 13, 14.
In step B, the bmc 1 determines to load one of the system image data 11 and 12 of the storage module 10 according to the first product identifier 21 recorded by the field replaceable unit 2, so as to perform a corresponding system monitoring function. In detail, the step B includes the following substeps.
At step B1, baseboard management controller 1 reads field replaceable unit 2 and performs analysis (parse) to obtain first product identifier 21.
In step B2, the bmc 1 determines whether there is a corresponding one of the stored system image data 11, 12 that matches the first product id 21.
In step B3, if the determination result in step B2 is yes, the bmc 1 determines to load the corresponding one of the system image data 11 and 12 of the storage module 10.
In step B4, if the determination result in step B2 is negative, the bmc 1 determines to load a predetermined one of the system image data 11, 12 of the storage module 10.
For example, the bmc 1 takes the system image data 11 applied to the a motherboard as the default, and when the first product identifier 21 read by the bmc 1 indicates the a motherboard, the bmc 1 determines to load the system image data 11 correspondingly; however, when the first product id read by the bmc 1 indicates a C motherboard different from the a motherboard, the bmc determines to load the system image data 11 because the system image data corresponding to the C motherboard cannot be found.
In step C, the bmc 1 further determines whether to load one of the candidate image data 13 and 14 to replace the one of the system image data 11 and 12 according to the second product identifier 22 recorded by the field replaceable unit 2.
For example, when the bmc 1 reads the motherboard a indicated as the original version by the second product identifier 22, the bmc 1 determines to keep loading the system image data 11; however, when the second product id 22 is read to indicate an updated version of the a' motherboard, the bmc does not load the system image 11 but determines to load the alternative image 13.
It should be noted that, generally, the system image data 11 for developing the a motherboard needs one source code, and the system image data 12 for developing the B motherboard needs another source code, where the source code is, for example, a program code written by a developer in C language, and the system image data 11, 12 is a binary code generated by compiling the source code, and after the developer writes two source codes for monitoring items of the a motherboard and the B motherboard and finishes compiling with a computer, two firmware mapping files (iso files) are generated, one is to record the system image data 11, and the other is to record the system image data 12, and the developer writes the two firmware mapping files into the storage module 100 of the baseboard management controller 1 of A, B motherboard respectively, and maintains the two source codes at the same time, such as debug, update, etc.
In other embodiments of the present invention, a developer may also write the same original code for the monitoring items of the a motherboard and the B motherboard, and generate a firmware mapping file after compiling, the firmware mapping file records the system mapping data 11 and the system mapping data 12 at the same time, and the a motherboard and the B motherboard store the firmware mapping file at the same time, and the substrate management controllers 1 of the a motherboard and the B motherboard determine which of the system mapping data 11 and 12 is to be loaded according to the first product identification code 21 read by the field replaceable unit 2, respectively. Therefore, for production line personnel, only one firmware mapping file needs to be recorded to the storage module 100 of the baseboard management controller 1 for different mainboards, so that the recording error probability can be reduced; for the developers, when the bmc 1 executes the system image data 11, 12 with errors, the same source code is shared, so the developers only need to modify the error once, and do not need to find out the respective source code for modification.
As can be seen from the above description, the baseboard management controller 1 of the present invention stores the system image data 11, 12 of the motherboards applied to different servers, and determines to load the motherboard according to the first product identification code 21, so that it is not necessary to perform recording according to the storage module 100 of the baseboard management controller 1 used by different motherboards during factory shipment, thereby effectively reducing the probability of recording errors. In addition, the system image data 11, 12 can share the same source code, because the research and development personnel do not need to correct the error for the respective source code, the research and development personnel can conveniently perform the firmware maintenance on the baseboard management controller 1, so that the baseboard management controller 1 can be applied to different servers, thereby achieving the purpose of the invention.
In summary, the above embodiments and drawings are only preferred embodiments of the present invention, but not intended to limit the scope of the present invention, and all equivalent changes and modifications made by the claims of the present invention should fall within the scope of the present invention.
