Method, apparatus and device for sharing password between BIOS and operating system

An apparatus for sharing a password between a basic input output system (BIOS) and an operating system, the apparatus applied to a Legacy boot mode and comprising:

• a password inputting module configured to prompt a logon user to input a password of the BIOS if it is detected in a process of power-on self-test that a password is set for the BIOS;
• a first verifying module configured to receive the password of the BIOS inputted by the logon user and verify the received password of the BIOS;
• a configuration table creating module configured to store the verified password of the BIOS in a predetermined target memory and create E820H information in a case that the received password of the BIOS is verified as correct, wherein address data in the E820H information points to an address of the target memory;
• a memory content acquiring module configured to determine the address of the target memory based on the created E820H information and acquire memory contents stored in the target memory, if it is detected that a password is set for the operating system;
• and
• a second verifying module configured to permit the logon user to log on the operating system in a case that the acquired memory contents are verified as correct.

A device for sharing a password between a basic input output system (BIOS) and an operating system, comprising:

• a memory configured to store programs;
• and
• a processor configured to execute the programs to perform operations of:
• prompting a logon user to input a password of the BIOS if it is detected in a process of power-on self-test that a password is set for the BIOS;
• receiving the password of the BIOS inputted by the logon user, and verifying the received password of the BIOS;
• storing the verified password of the BIOS in a predetermined target memory and creating E820H information in a case that the received password of the BIOS is verified as correct, wherein address data in the E820H information points to an address of the target memory;
• determining the address of the target memory based on the created E820H information and acquiring memory contents stored in the target memory, if it is detected that a password is set for the operating system;
• and
• permitting the logon user to log on the operating system in a case that the acquired memory contents are verified as correct.
