[ detailed description ] embodiments
Fig. 1 is a block diagram illustrating an embodiment of a server apparatus according to the present disclosure. Referring to fig. 1, the server device includes a motherboard 11, a first non-volatile memory unit 12, a second non-volatile memory unit 13, and a processing unit 14. The main board 11 has a version number (hereinafter referred to as a first version number), the first non-volatile memory unit 12, the second non-volatile memory unit 13 and the processing unit 14 are disposed on the main board 11, and the processing unit 14 is coupled to the first non-volatile memory unit 12 and the second non-volatile memory unit 13.
The first NVM unit 12 stores a Basic Input/Output System (BIOS) program code having another version number (hereinafter referred to as a second version number).
After the server device is powered on, the processing unit 14 reads the first nonvolatile memory unit 12 to execute the BIOS program code, and the processing unit 14 executes a Power On Self Test (POST) procedure of the server device. In the boot self-test procedure, referring to fig. 1 and 2, the processing unit 14 determines whether the first version number matches the second version number according to the first version number and the second version number (step S01), when the first version number does not match the second version number (the determination result is "no"), the processing unit 14 stores the determination result (hereinafter referred to as the first determination result) indicating that the first version number does not match the second version number in the second nonvolatile memory unit 13 (step S02), and the processing unit 14 stops executing the boot self-test procedure of the server apparatus (step S03), so that the boot self-test procedure is suspended.
For example, taking the example that the processing unit 14 determines whether the first version number is the same as the second version number in step S01 to determine whether the first version number is matched with the second version number, taking two digits represented by binary codes as an example, when the first version number and the second version number are "01" and "11", respectively, the processing unit 14 determines that the first version number is not the same as the second version number, and the processing unit 14 generates a determination result that the first version number is not matched with the second version number.
Herein, if the BIOS program code and the motherboard 11 with unmatched version numbers are used when the server device is manufactured at the factory, when the server device is tested, the tester can know that the BIOS program code and the version number of the motherboard 11 are unmatched according to the suspended power-on self-test procedure at the power-on self-test stage of the server device; on the other hand, if the BIOS program code with the version number matching with the motherboard 11 is used at the factory, after the server device is sold (hereinafter referred to as the consumer), if the BIOS program code is updated by the user, which causes the BIOS program code not matching with the version number of the motherboard 11, the user can know that the BIOS program code does not match with the version number of the motherboard 11 during the power-on self-test stage of the server device according to the suspended power-on self-test procedure. Therefore, no matter at the factory or the consumer, the tester and the user can immediately know that the BIOS program code is not matched with the version number of the motherboard 11, so as to know in advance and avoid the problem of unstable server device caused by the operation of the server device based on the BIOS program code with the version number not matched with the motherboard 11.
In one embodiment, the first version number and the second version number may represent manufacturer information or firmware version information. The second nonvolatile memory unit 13 may be a field-replaceable unit (FRU).
In one embodiment, in step S01, if the processing unit 14 determines that the first version number is the same as the second version number (yes), the processing unit 14 may store another determination result (hereinafter referred to as a second determination result) indicating that the first version number and the second version number are matched in the second nonvolatile memory unit 13 (step S04), and the second determination result and the first determination result are not mutually overlapped. For example, if the first version number and the second version number which are correctly matched are used when the server device is manufactured at the factory, the processing unit 14 executes step S04 according to the matched first version number and second version number (yes) in the power-on self-test procedure at the test stage to store the second determination result in the second nonvolatile memory unit 13; as for the customer end, if the user updates the wrong BIOS program code by himself, the processing unit 14 executes step S02 to store the first determination result in the second non-volatile memory unit 13 according to the first version number and the second version number that are not matched (the determination result is "no") in the power on self-test procedure, at this time, the second non-volatile memory unit 13 stores the first determination result and the second determination result, if the user wants to repair the server device, the maintainer of the server device can further perform debugging and repair according to the first determination result and the second determination result that exist at the same time.
In one embodiment, taking the example that "0" at low logic level and "1" at high logic level respectively indicate that the first version number and the second version number match or do not match, in step S04, processing unit 14 may store "0" at low logic level in second nonvolatile memory unit 13, and in step S02, processing unit 14 may store "1" at high logic level in second nonvolatile memory unit 13 to distinguish the determination result that the first version number matches or does not match the second version number.
In summary, if the first version number and the second version number that are correctly matched are used when the server device is manufactured at the factory and the BIOS program code is not updated by the user, after the processing unit 14 determines that the first version number matches the second version number (the determination result is yes), the processing unit 14 continues to execute the power-on self-test program (step S05), and after the power-on self-test program is completed, the processing unit 14 executes an Operating System (OS). In the operating system, the second non-volatile memory unit 13 is in the read and write locked state, that is, the user of the server device cannot obtain the second determination result stored in the second non-volatile memory unit 13 by reading the second non-volatile memory unit 13 in the operating system, that is, the user cannot change the second determination result stored in the second non-volatile memory unit 13, in other words, the second determination result is hidden information, so that the determination result that the user has determined that the BIOS program code matches the version number of the motherboard 11 in the test stage by the modification processing unit 14 can be avoided.
In one embodiment, as shown in fig. 1, the server device further includes a display unit 16 coupled to the processing unit 14, and referring to fig. 3, when the processing unit 14 determines that the first version number does not match the second version number after performing step S01 (the determination result is "no"), the processing unit 14 may drive the display unit 16 to display an alert message (step S07) to prompt the manufacturer or user of the server device that the BIOS program code currently used by the manufacturer or user does not match the motherboard 11. Wherein the warning message can be a text, a pattern or a combination of text and pattern.
In one embodiment, in step S04, the processing unit 14 may further store time information in the second non-volatile memory unit 13, wherein the time information includes a date and a time when the version number of the motherboard 11 matches the version number of the BIOS program code; in step S04, the processing unit 14 may further store the matched BIOS program code and the version number of the motherboard 11 in the second non-volatile memory unit 13. Then, if the processing unit 14 determines that the BIOS program code does not match the version number of the motherboard 11, in step S07, the processing unit 14 may further drive the display unit 16 to display the BIOS program code that is previously matched with the version number of the motherboard 11 and the previous time information according to the information stored in the second nonvolatile memory unit 13, and drive the display unit 16 to display the BIOS program code that is currently unmatched with the version number of the motherboard 11, so that the inspector of the server device may confirm that the time when the BIOS program code is unmatched with the version number of the motherboard 11 is later than the previous time information according to the time information displayed by the display unit 16, and perform maintenance and debugging according to the previously matched version number and the current version number.
For example, if the manufacturer uses the version number of the motherboard 11 and the version number of the BIOS program code (hereinafter referred to as the fourth version number) that are correctly matched, for example, two digits represented by binary code, the fourth version number may be "01", in the test procedure, taking the aforementioned first version number of the motherboard 11 as "01", as an example, if the processing unit 14 executes the power on self test procedure in 1 month and 1 day of 107 years, the processing unit 14 executes step S04 according to the first version number and the fourth version number that are both "01" and correctly matched after executing step S01, and the processing unit 14 stores the first version number and the fourth version number that are both "01" and the time information of 1 month and 1 day of 107 years in the second nonvolatile memory unit 13 in step S04; then, when the server device is sold to the consumer, if the user of the server device updates the wrong BIOS program code by himself/herself, so that the first version number of the motherboard 11 does not match the version number of the BIOS program code (hereinafter referred to as the second version number), for example, the second version number is "11", the processing unit 14 executes step S07 according to the erroneously matched first version number and second version number after executing steps S01 and S02, and the processing unit 14 drives the display unit 16 to display the warning message, the fourth version number of "" 01 ", the time information of 1 month and 1 day in 107 years, and the first version number and the second version number, which are" 01 "", "11" respectively at present in step S07. Thus, the inspector of the server device can perform maintenance and debugging according to the display information.
In one embodiment, as shown in FIG. 3, when the processing unit 14 determines in step S01 that the version number of the motherboard 11 does not match the version number of the BIOS program code (NO), the display unit 16 further displays a password input screen in step S07. When the user keys in the password in the server device, the processing unit 14 receives the input password keyed in by the user, and the processing unit 14 further compares the input password with the default password to determine whether the user has the authority to refresh the BIOS program code according to the input password keyed in by the user. Then, the processing unit 14 determines whether the input password is the same as the default password (step S06), when the input password is the same as the default password (yes), it indicates that the user has the authority to refresh the BIOS program code, the processing unit 14 continues to execute the power-on self-test program of the server device (step S05), and after the power-on self-test program is completed, the user can refresh the BIOS program code again to update the version number of the BIOS program code; when the input password is different from the default password (no), it indicates that the user does not have the authority to refresh the BIOS program code, the processing unit 14 does not continue to execute the power-on self-test procedure of the server device, so that the power-on self-test procedure of the server device is maintained in a suspended state (step S03), and the user cannot refresh the BIOS program code again.
In one embodiment, the default password is held by a service provider of the server device, and only the service provider has the authority to refresh the BIOS program code; alternatively, the user of the server device can obtain the default password from the service provider to refresh the BIOS program code by itself.
In one embodiment, the version number of the motherboard 11 can be represented by binary code, and as shown in fig. 1, the processing unit 14 includes a processor 141 and a platform Path Controller (PCH) 142, wherein the processor 141 is coupled to the PCH 142. The stage path controller 142 includes a number generation circuit composed of a pull-up resistor and a ground resistor. After the server device is powered on, the pull-up resistor and the ground resistor can generate a version number (e.g., the aforementioned first version number) of the motherboard 11 represented by binary codes. Accordingly, in step S01, the processing unit 14 executes the BIOS program code to actively send a request signal requesting the version number of the motherboard 11 to the platform path controller 142 when executing the power on self-test procedure, and when the processor 141 sends the request signal, the number generation circuit of the platform path controller 142 outputs the version number of the motherboard 11 represented by binary code. After the processing unit 14 obtains the version number of the motherboard 11 from the platform path controller 142, the processing unit 14 executes step S01 according to the version number included in the BIOS program code to determine whether the version number of the motherboard 11 matches the version number of the BIOS program code.
In one embodiment, when the version number of the motherboard 11 is not matched with the version number of the BIOS program code, the processing unit 14 triggers a System Event Log (SEL) of the server device, where the System Event Log at least includes abnormal information that the version number of the motherboard 11 is not matched with the version number of the BIOS program code. In detail, as shown in fig. 1, the server device further includes a baseboard management control unit (BMC) 15 coupled to the processing unit 14, taking the first version number and the second version number as an example, when the processing unit 14 determines that the first version number and the second version number are not matched, the processing unit 14 triggers the baseboard management control unit 15 (step S07), so that the baseboard management control unit 15 records the second determination result, the corresponding fourth version number, the warning message, the time information, and the first version number and the second version number that are not matched currently in the system event log, so that a manager of the server device can query the system event log by using the baseboard management control unit 15 in a remote connection manner.
In summary, according to an embodiment of the server apparatus in the present disclosure, the processing unit can determine whether the version number of the motherboard matches the version number of the BIOS program code, and whether the processing unit is at a factory or a consumer, the processing unit can detect the unmatched version number in the power-on self-detection procedure, so as to avoid the problem of unstable operation of the server apparatus, and can prompt the user that the version number of the BIOS program code does not match the version number of the motherboard by displaying an alert message. Furthermore, the processing unit can record the judgment result that the version numbers of the main board and the BIOS program code are matched or not matched in the non-volatile memory, and the two judgment results are hidden information which are not mutually covered, so that the inspector can perform the maintenance and debugging of the server device accordingly.
Although the present disclosure has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the disclosure, and the scope of the disclosure is to be determined by the appended claims.
