Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0016] The first embodiment of the present invention relates to a method for locating BIOS codes during a shutdown. The specific process is as figure 1 shown.

[0017] Step 101: Initialize M storage locations pre-selected from the non-volatile memory.

[0018] In order to prevent the stored data from being lost when the terminal is down,...

Abstract

The invention relates to the technical field of information processing, and discloses a method and device for positioning downtime BIOS codes. The method comprises the steps of initializing M preselected storage locations in a non-volatile memory, wherein the M storage locations include a first storage location which is used for storing a BIOS code which is output when a BIOS is operated for starting up; moving the data stored in the first storage location to a corresponding offset location for storage after every start-up and before a first BIOS code is output, wherein the offset location is a storage location other than the first storage location in the M storage locations; if a crash occurs in the process of outputting the BIOS code, reading data in an offset position corresponding to the first storage location after a next start-up, and adopting the BIOS code as the last output BIOS code before the crash. According to the embodiment, no hardware is needed to be added, which position the codes in the BIOS runs to can be clearly understood when the crash occurs in a start-up stage, and therefore the reduction of the cost is facilitated.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and a device for locating BIOS codes during downtime. Background technique [0002] In the research and development process of terminals such as notebook computers, the problem of downtime often occurs during the process of booting and running BIOS (Basic Input Output System, that is, Basic Input Output System) code. At this time, it is necessary to locate the BIOS in the case of downtime Where did the code go, in order to troubleshoot (ie debug). [0003] The existing technology generally inserts a specific 80 card to check where the problem is, and where the code in the BIOS went when the system crashed. But customizing a special 80 card will undoubtedly increase the cost, and for probabilistic problems, not every computer can solve the problem by plugging in an 80 card and turning it on. Contents of the invention [0004] The purpose of the embodime...
