Abstract

The invention discloses a computer device with mobile basic input and output system which is distributed with a containing groove. A mobile basic input and output system stores a basic input and output system code, the basic input and output system possesses signal feet corresponding with connecting point of the containing groove seat, and it can be inserted into the basic input and output system containing groove seat, and makes the signal feet connected with connecting point. When the computer device is started, central processor images the basic input and output system to the main memory, and system code of the basic input and output system can be executed. The computer device provided by the invention can fulfill high-safety requirement, high-stability requirement or army requirement.

Description

technical field [0001] The present invention relates to a computer device, in particular to a computer device with a pluggable basic input / output system. Background technique [0002] At present, when a typical computer device is turned on, it will firstly perform a standard system basic startup procedure. In order to achieve this system basic startup procedure, a basic input-output system (Basic Input and Output System, referred to as BIOS) is provided on the motherboard of the computer device, and the basic input-output system is pre-stored in the basic input-output system. Code, and the BIOS code includes the BIOS program and the system self-test program. Therefore, when the computer device is turned on, the CPU will load and execute the BIOS program and the system self-test program from the BIOS memory. In the current design, the CPU of the computer device shadows the BIOS code in the BIOS to the system memory, and executes the BIOS code. [0003] After the computer d...
