Problems solved by technology

[0002] In the existing method for obtaining the system signature, the reading time of the system signature is too long, that is, it needs to be read after the system is started. At this time, a long time has passed, causing the system to be unsafe; and the computer starts from the disk or winpe Programs installed in the operating system, such as booting from the CD-ROM, cannot obtain feature codes

Embodiment 1

[0037] The method for obtaining feature codes safely and quickly by extending the BIOS of the present embodiment includes the following steps:

[0038] (1) Power on the computer system by powering on the system;

[0039] (2) Perform operations such as computer system self-inspection initialization by system self-inspection;

[0040] (3) The main BIOS (Basic Input Output System) performs self-test and calls the extended BIOS;

[0041] (4) Read the system feature code by the extended BIOS, save the obtained system feature code in the main BIOS, and transmit it through the communication interface; return the control right to the main BIOS, and the main BIOS will continue to execute ;

[0042] (5) It will be executed according to the corresponding system feature code and preset restrictions.

[0043] The connection interface between the extended BIOS and the main BIOS is a PIC interface. The transmission is output through the serial port. The system feature code read in the s...

Embodiment 2

[0045] The method for obtaining feature codes safely and quickly by extending the BIOS of the present embodiment includes the following steps:

[0046] (1) Power on the computer system by powering on the system;

[0047] (2) Perform operations such as computer system self-inspection initialization by system self-inspection;

[0048] (3) The main BIOS (Basic Input Output System) performs self-test and calls the extended BIOS;

[0049] (4) Read the system feature code by the extended BIOS, save the obtained system feature code in the main BIOS, and transmit it through the communication interface; return the control right to the main BIOS, and the main BIOS will continue to execute ;

[0050] (5) It will be executed according to the corresponding system feature code and preset restrictions.

[0051] The connection interface between the extended BIOS and the main BIOS is a PIC interface. The transfer is output via USB. The system feature code read in the step (4) includes the...

Embodiment 3

[0053] The method for obtaining feature codes safely and quickly by extending the BIOS of the present embodiment includes the following steps:

[0054] (1) Power on the computer system by powering on the system;

[0055] (2) Perform operations such as computer system self-inspection initialization by system self-inspection;

[0056] (3) The main BIOS (Basic Input Output System) performs self-test and calls the extended BIOS;

[0057] (4) Read the system feature code by the extended BIOS, save the obtained system feature code in the main BIOS, and transmit it through the communication interface; return the control right to the main BIOS, and the main BIOS will continue to execute ;

[0058] (5) It will be executed according to the corresponding system feature code and preset restrictions.

[0059] The connection interface between the extended BIOS and the main BIOS is a SATA interface. The transmission is output through the serial port. The system feature code read in the ...

Abstract

A method for shortening time from starting to feature code obtaining and safely and quickly obtaining feature codes through an extended BIOS comprises the following steps of (1) electrifying a computer system through system electrification; (2) performing computer system self-inspection initialization and other operations through system self-inspection; (3) performing self-inspection execution through a main BIOS (Basic Input Output System) and invoking the extended BIOS; (4) reading the system feature codes through the extended BIOS and transmitting the system feature codes through a communication interface; (5) performing execution according to the corresponding system feature codes and the preset limiting condition. The computer system feature codes can be quickly obtained through the extended BIOS, and the time from starting to feature code obtaining is shortened. The problem that program in an operating system can be used after disk starting, winpe starting, CD-ROM starting and other operation and the time for feature code obtaining is long is solved. In addition, the obtaining operation does not completely depend on the operating system, and the influence of virus, Trojan and the like is avoided, so that the feature code obtaining operation is safe.

Description

technical field [0001] The invention relates to a method for acquiring a feature code, in particular to a method for safely and quickly acquiring a feature code by extending BIOS. Background technique [0002] In the existing method for obtaining the system signature, the reading time of the system signature is too long, that is, it needs to be read after the system is started. At this time, a long time has passed, causing the system to be unsafe; and the computer starts from the disk or winpe Programs installed in the operating system, such as booting from the CD-ROM, cannot obtain feature codes. Contents of the invention [0003] The invention provides a method for securely and quickly acquiring feature codes by extending the BIOS and reducing the time from booting to acquiring feature codes. [0004] Realize the method for obtaining feature code safely and quickly by expanding BIOS of the purpose of the present invention, comprise the steps: [0005] (1) Power on the ...
