Embodiment 1

[0071] Such as figure 1 As shown, the present invention provides a kind of solution AFU tool refreshes the method that BIOS carries out password verification, comprises the steps:

[0072] The S1.BIOS end defines a password function inspection module, and the password function inspection module checks whether there is a password information flag at the BIOS end, and when there is a password information flag, establishes a link between the password function inspection module and the AFU tool;

[0073] S2. When running the AFU tool to refresh the BIOS, the password function inspection module at the BIOS end is automatically triggered, and the password function inspection module interrupts the BIOS refresh operation, starts a password request, and judges whether there is a password and whether the requested password is the same as the pre-stored password;

[0074] S3. When the requested password is the same as the pre-stored password, the password function inspection module on th...

Embodiment 2

[0077] Such as figure 2 As shown, the present invention provides a kind of solution AFU tool refreshes the method that BIOS carries out password verification, comprises the steps:

[0078] S1.BIOS end defines password function inspection module, whether password function inspection module checks BIOS end and whether there is password information flag bit, and when there is password information flag bit, establishes the link of password function inspection module and AFU tool; Concrete steps are as follows:

[0079] S11. Register the instruction signal of the AFU tool communicating with the BIOS at the BIOS end and the AFU end, including a password existence signal, a password acquisition signal, and a password verification signal;

[0080] S12. define the password existence mark position, password acquisition mark position and password verification mark position at BIOS end; The password existence mark position is used to indicate whether the password existence signal exists,...

Embodiment 3

[0103] Such as figure 2 As shown, the present invention provides a kind of solution AFU tool refreshes the method that BIOS carries out password verification, comprises the steps:

[0104] S1.BIOS end defines password function inspection module, whether password function inspection module checks BIOS end and whether there is password information flag bit, and when there is password information flag bit, establishes the link of password function inspection module and AFU tool; Concrete steps are as follows:

[0105]S11. Register the command signal of the AFU tool and BIOS communication at the BIOS end and the AFU end, including the existence of the PasswordExist signal of the password, the password acquisition of the PasswordGet signal and the password verification PassworCheck signal;

[0106] S12. define the password existence mark position, password acquisition mark position and password verification mark position at BIOS end; The password existence mark position is used to...

Abstract

The invention provides a method and a device for achieving password verification by refreshing a BIOS through an AFU tool. The method comprises the following steps: defining a password function verification module at a BIOS end, checking whether a password flag bit exists or not, and building a link between the password function verification module and the AFU tool when the password flag bit exists; when the AFU tool is operated to carry out BIOS refreshing, automatically triggering the password function verification module, interrupting BIOS refreshing operation, starting a password request, and judging whether a password exists or not and whether a requested password is the same as a pre-stored password or not; when the request password is the same as the pre-stored password, notifying the AFU to continue BIOS refreshing; when the request password is different from the pre-stored password and a requesting number of times of password exceeds a limit number, stopping the AFU tool from BIOS refreshing. According to the method and the device, the user password verification is carried out when the AFU tool is used for refreshing in the band, so that a series of problems caused by improper BIOS refreshing are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of BIOS refreshing, and in particular relates to a method and a device for solving the problem of password verification for AFU tools refreshing BIOS. Background technique [0002] BIOS is the abbreviation of Basic Input Output System, basic input output system. As the bottom layer of the server motherboard, the BIOS is the most direct hardware setting and control management terminal, which can provide more simple and easy-to-use functions for the server. The BIOS can be refreshed in two ways, in-band and out-of-band. The commonly used tool for in-band BIOS refresh is the AFU tool. [0003] The AFU tool is a utility toolkit used to update the system BIOS under various systems, and it can help users update the BIOS under EFI Shell, Linux and Windows. At present, there is no security verification mechanism when using the AFU tool to update the BIOS. No matter ordinary users or administrators, as long as they...
