Embodiment Construction

[0010] Please refer to figure 1 , is a flowchart of a method for establishing a system licensing internal code (System licensing internal code, SLIC table) according to the first embodiment of the present invention. Wherein, the system authorized internal code is used in a basic input / output system. The BIOS includes a system management module. First, step 100 is executed to determine whether a preloaded system lock (System locked preinstallation, SLP) location in the system management module has data. In this embodiment, the judging process is based on whether the preloaded system lock location is FFFF or not. If it is FFFF, it means that there is no data, which means that the basic input / output system has not been started after the manufacturing is completed, so no data has been written, so that the preloaded system lock position remains at the default FFFF. Conversely, if the preloaded system lock position is not FFFF, it means that the basic input / output system has been...

Abstract

The invention discloses a method for establishing a system licensed internal code, which is applied to a basic input / output system, wherein the basic input / output system comprises a system management module. The method for establishing the system licensed internal code comprises the following steps: judging whether the position of a preloaded system lock in the system management module has data, and if the position has the data, judging whether the data of the position of the preloaded system lock is a specific data; and if the data is not the specific data, establishing the system licensed internal code according to the data of the position of the preloaded system lock.

Description

technical field [0001] The present invention relates to a method of establishing a system authorized internal code, and in particular relates to a method of establishing a system authorized internal code for a basic input / output system. Background technique [0002] The ever-changing development of computer software has also brought about an increasingly serious problem of piracy. Especially on the operating system, the problem of piracy is becoming more and more rampant. Piracy techniques of operating systems emerge in endlessly, the most well-known of which is to steal verification information through original equipment manufacturer (OEM). [0003] After a mainboard is turned on, the BIOS will create a system licensed internal code (Systemlicensing internal code, SLIC table), and the verification information will be read from the BIOS and established in the system licensed internal code . Then the operating system is compared according to the licensed internal code of t...
