[ detailed description ] of the invention
FIG. 1 is a block diagram of an embodiment of a server to which the BIOS setup menu generation method of the present invention is applied, refer to FIG. 1. The server includes a memory unit 11 and a processing circuit 12 coupled to the memory unit 11. The memory unit 11 stores BIOS program codes, settable BIOS setting options, default management passwords and default maintenance passwords. The default management password corresponds to the highest operation authority of the server, and an administrator of the server can freely select each settable BIOS setting option in a BIOS setting menu (BIOS setting menu) by means of the default management password and modify the set value of the selected BIOS setting option, for example, set the BIOS setting option to be enabled (enabled) or disabled (disabled); and, the manager of the server can view the confidential information of the server in the BIOS setting menu by default management password.
The default maintenance password is the lowest operation authority of the corresponding server, that is, the operation authority of the default maintenance password is lower than the operation authority of the default management password, the default maintenance password is used by external maintenance personnel for maintaining the server, when the external maintenance personnel enter the BIOS setting menu by the default maintenance password, the maintenance personnel cannot freely select the settable BIOS setting option, the server can shield (for example, hide display or gray display) the BIOS setting option irrelevant to the maintenance server, the server hides the confidential information of the server, that is, the server only provides the BIOS setting option required for maintenance, so as to avoid the external maintenance personnel from unauthorized modification of the BIOS setting option irrelevant to the maintenance server without approval of the manager, and avoid the external maintenance personnel from acquiring the confidential information of the server in the BIOS setting menu by means of the maintenance server.
Therefore, the processing circuit 12 can read the memory unit 11 to obtain the BIOS program code, and execute the BIOS program code to generate a password input field in the power-on self-detection program of the server for the operator to execute the password input action, after the operator executes the password input action, the processing circuit 12 receives the input password, and the processing circuit 12 determines that the input password is input, and the processing circuit 12 provides corresponding different BIOS setting menus (hereinafter referred to as a first BIOS setting menu and a second BIOS setting menu for convenience of description) for the default maintenance password or the default management password according to the input password. Referring to fig. 1 and 2 in combination, in the power-on self-test procedure of the server, the processing circuit 12 determines that the received input password is a default management password or a default maintenance password, the processing circuit 12 compares the input password with the default management password to determine whether the input password meets the default management password (step S01), and the processing circuit 12 compares the input password with the default maintenance password to determine whether the input password meets the default maintenance password (step S02).
When the processing circuit 12 determines in step S01 that the input password meets the default management password (yes in the determination result), the processing circuit 12 executes the first BIOS setting menu (step S03), the first BIOS setting menu displays each settable BIOS setting option and the confidential information of the server, the manager can freely select the BIOS setting option to be set in the first BIOS setting menu, and the manager can confirm whether the confidential information is correct. On the other hand, when the processing circuit 12 determines in step S02 that the input password matches the default maintenance password (yes in the determination result), the processing circuit 12 executes the second BIOS setting menu, as shown in fig. 3, in which the second BIOS setting menu displays the boot device setting option 2 and the BIOS setting Save and Exit (Save and Exit) option 3 related to the maintenance server, and shields the BIOS setting option unrelated to the maintenance server and hides the related option of the confidential information of the server.
Thus, the external serviceman can only modify the boot device setting option 2, for example, as shown in fig. 3, the boot device used For booting the server, the priority order (Boot OptionPriorities) between the boot devices (For example, executing the boot program with an optical drive, a flash drive or a hard disk), adding or deleting the boot device, the "quick boot" option defined by the Unified Extensible Firmware Interface (UEFI), the "Endlessboot" option and the "Wait For" ESC "If Error" option, the external serviceman can select the BIOS setting storage and the leaving option 3 after modifying the boot device setting option 2, the processing circuit 12 executes the BIOS setting storage and the leaving option 3, so that the server stores the modified boot device setting and restarts, and the modified boot device setting is validated. Therefore, the second BIOS setting menu can avoid that an external serviceman does not have the consent of the manager and does not have permission to modify BIOS setting options irrelevant to the maintenance server, and avoid that the external serviceman obtains confidential information of the server when the external serviceman is used for maintaining the server.
In one embodiment, the confidential information of the server is information that does not allow maintenance personnel to know, and the designer of the server can design the confidential information by himself. For example, as shown in FIG. 4, the confidential information may be the system date and time of the server, the version number of the BIOS program code, the product name and memory unit capacity of the server, and the default management password (not shown), and as shown in FIG. 5, the confidential information may be an authentication key used to authenticate the operating system software and hardware drivers (i.e., security Boot). As can be seen from comparing FIGS. 3 and 4, the processing circuit 12 may not display the confidential information when executing the second BIOS setting menu to mask the options of the confidential information.
In an embodiment, a designer of the server may implement the first BIOS setting menu and the second BIOS setting menu with different program codes in advance, the different program codes corresponding to the first BIOS setting menu and the second BIOS setting menu may be stored in the memory unit 11, and the program codes of the first BIOS setting menu and the second BIOS setting menu may be a part of the BIOS program codes. Then, in steps S03 and S04, the processing circuit 12 determines whether each BIOS setting option is displayed on the first BIOS setting menu and the second BIOS setting menu according to the program codes corresponding to the first BIOS setting menu and the second BIOS setting menu, and determines whether the confidential information of the server is displayed on the first BIOS setting menu and the second BIOS setting menu. The processing circuit 12 can read the memory unit 11 to obtain the program code corresponding to the first BIOS setting menu in step S03, and the processing circuit 12 can read the memory unit 11 to obtain the program code corresponding to the second BIOS setting menu in step S04, that is, the processing circuit 12 determines to read the program code of the first BIOS setting menu or the program code of the second BIOS setting menu from the memory unit 11 according to the input password as the management password or the maintenance password.
In one embodiment, the server designer may set a custom page 4 in the second BIOS settings menu and store the boot device settings option 2 and BIOS settings associated with the maintenance server and leave option 3 in custom page 4. FIG. 6 is a diagram of a custom page of one embodiment of a second BIOS setting menu, please refer to FIG. 6. When the processing circuit 12 executes the second BIOS setting menu in step S04, the original pages defined by EFI or UEFI in the second BIOS setting menu (hereinafter referred to as EFI definition page and UEFI definition page) may be set to gray-scale display, for example, the original pages of "Advanced page", "Chipset page", "ServerMgmt page" and "Security page" may be gray-scale display, so that the external serviceman cannot modify the BIOS setting options in the original pages, and the external serviceman can only use the boot device setting option 2 and BIOS setting store in the custom page 4 and leave the option 3 setting. Alternatively, the EFI definition page or UEFI definition page 5 may be set as a hidden display, that is, the original page cannot be viewed by the external serviceman in the second BIOS setting menu, so as to truly hide the BIOS setting page irrelevant to maintenance.
Alternatively, in another embodiment, the Boot device setting option 2 and the BIOS setting storage and the leaving option 3 related to the maintenance server may also be set in the EFI definition page or the UEFI definition page 5, for example, as shown in fig. 3, the Boot device setting option 2 may be set in the EFI definition page or the UEFI definition page 5 of the "Boot page", the BIOS setting storage and the leaving option 3 may be set in the EFI definition page or the UEFI definition page 5 of the "Save & Exit page", and the EFI definition page or the UEFI definition page 5 further includes other BIOS setting options unrelated to maintenance, and the other BIOS setting options unrelated to maintenance may be set as gray-scale display or hidden display. As shown in fig. 3 and 4, the BIOS setting pages "Advanced page", "Chipset page", "Server Mgmt page" and "Security page" which are not related to maintenance are shown in the first BIOS setting menu only, and the BIOS setting pages which are not related to maintenance are not shown in the second BIOS setting menu.
In one embodiment, in the power-on self-test procedure, the operator of the server may press a keyboard key in the power-on self-test procedure to generate a first key information for hot key information to trigger the processing circuit 12 to execute the BIOS setting menu determining procedure in the power-on self-test procedure, so as to determine whether to execute the first BIOS setting menu or the second BIOS setting menu. Thus, in the BIOS setting menu decision program, the operator can press a different key of the keyboard according to the operator or an external maintenance person to generate the second key information, which is the first key information or the second key information, and the first key information and the second key information can trigger the processing circuit 12 to selectively execute the step S01 or the step S02, respectively, so as to compare the input password with the default management password (step S01) or the input password with the default maintenance password (step S02).
Specifically, the memory unit 11 may store the hot key information, the first key information and the second key information, the processing circuit 12 may determine whether the first key information corresponds to the hot key information in the power-on self-test procedure (step S05), when the first key information corresponds to the hot key information (yes in the determination result), the processing circuit 12 executes the BIOS setting menu decision procedure, in the BIOS setting menu decision procedure, the processing circuit 12 further determines whether the second key information corresponds to the first key information (step S06), when the second key information corresponds to the first key information (yes in the determination result), the processing circuit 12 generates a password input field for the operator to perform the password input operation, and the processing circuit 12 determines whether the input password corresponds to the default management password after receiving the input password (step S01); on the other hand, in the BIOS setting menu decision program, the processing circuit 12 may determine that the second key input information corresponds to the second key input information (step S07), and when the second key input information corresponds to the second key input information (yes), the processing circuit 12 generates a password input field for the operator to perform the password input operation, and the processing circuit 12 determines whether the input password corresponds to the default maintenance password after receiving the input password (step S02). In which the order of steps S06 and S07 may be exchanged or parallel, fig. 2 is only for illustration, and the processing circuit 12 performs step S06 and then step S07.
In one embodiment, the hot key information may correspond to the "Del" key or the "F2" key of the keyboard, the first key information may correspond to the "F1" key of the keyboard, and the second key information may correspond to the "F10" key of the keyboard. When the operator presses the "Del" button or the "F2" button, the processing circuit 12 executes the BIOS setting menu decision procedure, when the operator presses the "F1" button in the BIOS setting menu decision procedure, the processing circuit 12 compares the input password with the default management password (step S01), and when the operator presses the "F10" button in the BIOS setting menu decision procedure, the processing circuit 12 compares the input password with the default maintenance password (step S02).
Accordingly, when the processing circuit 12 determines in step S01 that the input password does not conform to the default management password (no), the processing circuit 12 may provide the password input field again to prompt the operator to re-input the password, at this time, the processing circuit 12 may count the number of password errors and determine whether the number of password errors reaches the preset number (step S08), if the number of password errors does not reach the preset number (no), the processing circuit 12 repeatedly provides the password input field to prompt the operator to re-input the password and repeatedly determines whether the input password conforms to the default management password (step S01), until the processing circuit 12 determines in step S08 that the number of password errors reaches the default number (yes), the processing circuit 12 generates an error message (step S09), and the error message may be displayed on the display of the server.
Similarly, when the processing circuit 12 determines in step S02 that the input password does not meet the default maintenance password (no), the processing circuit 12 may provide the password input field again to prompt the operator to input the password again, at this time, the processing circuit 12 may count the number of password errors and determine whether the number of password errors reaches the preset number (step S10), if the number of password errors does not reach the preset number (no), the processing circuit 12 repeatedly provides the password input field to prompt the operator to input the password again and repeatedly determines whether the input password meets the default maintenance password (step S02), until the processing circuit 12 determines in step S10 that the number of password errors reaches the default number (yes), the processing circuit 12 generates an error message (step S11), and the error message may be displayed on the display of the server.
In one embodiment, taking the foregoing hot key information corresponding to the "Del" key or the "F2" key of the keyboard as an example, if the operator does not press the "Del" key or the "F2" key in the power-on self-test procedure to generate the hot key information, it means that the processing circuit 12 does not need to execute the BIOS setting menu decision procedure in the power-on self-test procedure, that is, the processing circuit 12 does not need to generate the password input field in the power-on self-test procedure, in other words, if the external serviceman does not need to enter the second BIOS setting menu, the external serviceman can complete the power-on operation of the server without inputting the maintenance password, and the external serviceman does not need to repeatedly input the maintenance password in the power-on self-test procedure other than the BIOS setting menu decision procedure to perform the power-on operation of the server. Then, when the external serviceman does not press the key of the keyboard in the power-on self-test procedure and does not generate the first key input information or the external serviceman presses the wrong key of the keyboard to cause the first key input information not to conform to the hot key information (NO in the judgment result of the step S05), the processing circuit 12 can continue to execute the power-on self-test procedure (step S12) so as to successfully complete the power-on operation of the server; when the processing circuit 12 determines that the second key input information does not match the first key input information and the second key input information (no in both steps S06 and S07), the processing circuit 12 does not execute the first BIOS setting menu and the second BIOS setting menu, and the processing circuit 12 may continue to execute the power-on self-detection procedure (step S12).
In one embodiment, processing circuitry 12 may be a Central Processing Unit (CPU) or a system on a chip (SOC). The memory cell 11 may be a non-volatile memory cell, such as a flash memory cell or an electrically erasable and rewritable read only memory (EEPROM) cell.
In summary, according to an embodiment of the BIOS setting menu generation method of the present invention, the second BIOS setting menu can mask the BIOS setting options irrelevant to maintenance and can hide the default management password of the server, so as to avoid the problem of unstable operation of the server caused by unauthorized modification of the BIOS setting options irrelevant to the maintenance server by an external maintenance personnel through the default management password. In addition, the second BIOS setting menu can also hide the key information of the authentication key, so as to avoid the problem that the server cannot identify illegal programs after the external maintenance personnel unauthorized replacement of the authentication key, thereby causing unstable operation of the server and avoiding the server from being implanted with Trojan programs. Furthermore, the processing circuit generates a password input field in the BIOS setting menu decision program according to the key input information of the keyboard key, if the keyboard key is not pressed, the external maintenance personnel can complete the startup operation of the server without inputting the maintenance password, and the external maintenance personnel does not need to repeatedly input the maintenance password in the startup self-detection program to perform the startup operation of the server.
Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but rather by the scope of the appended claims.
