A kind of collocation method of aforesaid computer system is characterized in that may further comprise the steps:
A) computing machine powers up when starting, and central processing unit at first extracts instruction from basic input/output system memory and begins to carry out part in it;
B) this subprogram initialization and drive the Computer Communications Interface hardware circuit;
C) search the Basic Input or Output System (BIOS) external memory by Computer Communications Interface;
D) find and check the remainder that wherein whether has the correct complete Basic Input or Output System (BIOS) of this computer system behind the Basic Input or Output System (BIOS) external memory;
E) there is then remainder read in the computing machine, carries out jumping to remainder the complete Basic Input or Output System (BIOS) of computer system.
A kind of collocation method of aforesaid computer system, if described step C does not find the Basic Input or Output System (BIOS) external memory, then program is out of service, system in case of system halt.
A kind of collocation method of aforesaid computer system, if described step D does not find the remainder of the complete Basic Input or Output System (BIOS) of this computer system, then program is out of service, system in case of system halt.
A kind of collocation method of aforesaid computer system, this collocation method also comprise from the Basic Input or Output System (BIOS) external memory and read the computer hardware configuration information, the step that computer hardware is configured.
Beneficial effect of the present invention is: the present invention is by storing the BIOS separated into two parts of computer system, and transforms bios program, thereby makes the people who only holds correct BIOS external memory could open computing machine; By the computer hardware configuration information is stored in the BIOS external memory, use different B IOS external memory to open computing machine thereby reach, hardware configuration is inequality.
Description of drawings
Fig. 1 is the principle block diagram of computer system of the present invention and collocation method thereof.
Embodiment
See also Fig. 1, computer system of the present invention comprises central processing unit (CPU) 1, Basic Input or Output System (BIOS) (BIOS) storer 2 and Basic Input or Output System (BIOS) (BIOS) external memory 3.BIOS storer 2 is connected with central processing unit 1 by bus; BIOS external memory 3 is connected with central processing unit 1 by Computer Communications Interface 4.
Be appreciated that in computing machine, BIOS be computing machine carry out the earliest, to the basic software that computer hardware detects and disposes, each type computer has its BIOS that matches, BIOS can be limited to and can only be used for a certain computing machine by customization.Bios program can separated into two parts, a part is performed the earliest, the most basic computer hardware is carried out initial configuration, it executes the back computing machine and still can not normally use, another part is the main part of BIOS, usually all compress storage, be responsible for decompress(ion) by a preceding part and contract to be loaded in the calculator memory and move.BIOS two parts are one to one, can not obscure with other program code, otherwise program can not be carried out.Computer system of the present invention is utilized this characteristic, by adding a BIOS external memory 3 and transforming the part that BIOS is performed the earliest, with the bios program separate storage.
The principle of work of the collocation method of computer system of the present invention is: computing machine powers up when starting, central processing unit 1 at first extracts instruction from BIOS storer 2 and begins to carry out the BIOS forward part, this subprogram initialization also drives the Computer Communications Interface hardware circuit, search BIOS external memory 3 by Computer Communications Interface, find BIOS external memory 3 backs to check the remainder that wherein whether has the correct complete BIOS of this computer system, there is then remainder read in the computing machine with the complete BIOS of computer system, execution jumps to remainder, read the computer hardware configuration information from BIOS external memory 3, computer hardware is configured.If the remainder that does not find BIOS external memory 3 or do not have the complete BIOS of this correct computing machine in the middle of this, then program is out of service, system in case of system halt.
