Abstract

The present invention is used in the burning in the system assembling stage during computer production. The burning method includes the at least the steps of: providing one burning program with the function of judging the specification of PROM; establishing several PROM burning modules; selecting corresponding PROM burning module based on the burning program; and burning the burning module corresponding to the PROM into the ROM.

Description

Method for burn-recording with selectively burning module

The present invention relates to a kind of method for burn-recording, particularly a kind of to have that selectivity burns be the method for burn-recording of module.

Fast erasable basic input/output (Flash BIOS) the content in the middle of the BIOS that refers to can control by software, this class BIOS is with voltage cancelling programmable read only memory (Electrical lyErasable Programmable Read-Only Memory usually; EEPROM) form occurs, and just computer system can use the power of electric current to change the central program of BIOS, and like this, the program in the middle of the BIOS also can " be upgraded " and be become newer version.

Flash BIOS the earliest occurs on motherboard, present every interface card that BIOS is arranged, also can make with flash BIOS, so that revise the program error (bug) of original bios program or be suitable for upgrading, for example display card, modem, SCSI card or the like, nearest many modems all claim and can be standard V.90 by K56 flex standard upgrade, use be the upgrade technique of flash BIOS.Programmable ROM (read-only memory) (Programmable Read-Only Memory; PROM) be divided into voltage cancelling programmable read only memory (EEPROM) but and cancelling programmable read only memory (Erasable Programmable Read-OnlyMemory; EPROM) function basically is identical, and when it disappeared at power supply, stored data still existed.In the time of only will eliminating the content that is stored in the inside, EEPROM directly eliminates with electronic signal to get final product, and EPROM is the mode with the ultraviolet ray irradiation.

Present many firmwares can use the content among the software change EEPROM, described content often is not easy the data that change for some, for example nonvolatile RAM (Non-Volatilty RandomAccess Memory) (NVRAM), program in the middle of the BIOS of motherboard and modem can use special program to change central firmware microprogram.Because each tame manufacturer does not have a standard to what EEPROM, so rewrite the stage in burning, everybody flow process and order and inequality, so add among the what BIOS if desired and write flow process, must write a procedure code (code) especially at employed manufacturer, but because BIOS storage area problem can not add the procedure code of supporting too many family, at most one to two family.If but because of producing and the buying factor, must use the EEPROM more than five to six families, will cause production and software engineer's puzzlement.

The purpose of this invention is to provide a kind of method for burn-recording, to be applicable to the EEPROM of how tame manufacturer with selectively burning module.

For achieving the above object, the method for burn-recording with selectively burning module of the present invention comprises the following step at least: provide one to have the burning program of judging different programmable read only memory specifications; Set up the burning module of several described programmable read only memory; Described burning module according to the selected corresponding described programmable read only memory of described burning program; The described burning module that reaches corresponding described programmable read only memory is burned onto in the ROM (read-only memory).

Adopt such scheme of the present invention, identification label and model in the burning program module that can write at each tame manufacturer in process of production, by the identification code (ID) that reads each label and model, burning module when selecting corresponding EEPROM as system assembles, and selected module is burned onto ROM (read-only memory) (Read-OnlyMemory; ROM) in.Can reach following effect according to the method that the present invention carried: (1) the present invention adds in the ROM (read-only memory) according to employed EEPROM, therefore, at EEPROM, only need write a burning program, has therefore saved many procedure codes.(2) solve the variability issues of the EEPROM of how tame manufacturer, the selection function when system assembles in the production run is provided is recognized the EEPROM that is supported, and also selects its corresponding burning module and be burned onto in the ROM (read-only memory).

Be clearer understanding purpose of the present invention, characteristics and advantage, the present invention is described in detail below in conjunction with accompanying drawing.

Fig. 1 is the arrangement plan of existing system BIOS;

Fig. 2 is the arrangement plan of system bios of the present invention: and

Fig. 3 is the process flow diagram according to method of the present invention.

The configuration of the Basic Input or Output System (BIOS) of computer (BIOS) in the past is divided into start-up routine block (Boot Block) 10 and 20 liang of parts of system's Basic Input or Output System (BIOS) (Svstem BIOS) as shown in Figure 1 haply.Basic Input or Output System (BIOS) storage area by the what computer is limited, can not add the procedure code of supporting too many family, at most the procedure code of one to two family, therefore the present invention will utilize one of them zone of computer Basic Input or Output System (BIOS) independently to divide out, the burning program 30 of the independent writable EEPROM of storage, as shown in Figure 2, burning data enters in the ROM (read-only memory) (ROM) if desired when system's Basic Input or Output System (BIOS) (System BIOS) 20 runnings, then can call out this burning program 30, corresponding EEPROM burning module is burned onto in the ROM (read-only memory) (ROM), to save unnecessary procedure code.

And Fig. 3 is the process flow diagram according to method of the present invention, wherein, system assembles is during the stage in the computer production run, at first must prepare a determining program (step 100), wherein said determining program also comprises a burning program 30, identification label and model (step 110) in the burning program module of writing at each tame manufacturer, by the identification code (ID) that reads each label and model, burning module (step 120) when selecting corresponding EEPROM as system assembles, and selected module is burned onto ROM (read-only memory) (Read-onlv Memory by described burning program 30; ROM) in (step 130).

Though the present invention is disclosed with described preferred embodiment; right its is not in order to limit the present invention; any person skilled in the art person; under the prerequisite that does not break away from spirit of the present invention; also can make all equivalences and change and the equivalence replacement, these equivalences change and equivalent replacement all should be included in the protection domain of patented claim of the present invention.
