In this regard, the technical solution adopted by the present invention is：
A kind of method that machine system updates SMBIOS static informations, the backboard of the cabinet of the machine system is provided withEEPROM, the EEPROM are connected to by backboard in the SMBUS buses of the PCH chips of mainboard；There is storage in the EEPROMSMBUS controllers inside the type identification of machine system, PCH obtain the type identification data inside EEPROM, so as to recognizeCorresponding machine system；Then according to the proprietary attribute of machine system, SMBIOS data structure tables are updated.
Using this technical scheme, by setting EEPROM in backboard, cabinet and mainboard are connected, communication is set up, knownOther machine system, adds machine system identification marking, BIOS obtains mark, and recognizes machine system according to mark, then updatesThe proprietary SMBIOS static informations of machine system.By so designing, without for same mainboard, different cabinets and difference are matched somebody with somebody againThe machine system put makes corresponding BIOS, and mainboard and BIOS are corresponded, and solve the numerous and diverse confusion of numerous software version managementsThe problem of, solve the problem of production process is error-prone.
As a further improvement on the present invention, the method for the machine system renewal SMBIOS static informations includes following stepSuddenly：
Step S1, starts BIOS, SMBUS controllers is initialized；
Step S2, SMBUS controller communicates with EEPROM, and obtains the type identification of the machine system in EEPROM, according to classType mark judges current machine system model, then according to the proprietary attribute of machine system, sets up proprietary SMBIOS staticInformation, next starts to update SMBIOS data structure tables.
As a further improvement on the present invention, the proprietary attribute of the machine system include systematic name, cabinet title,PCIE device splits classifying type and PCIE slot quantity.
As a further improvement on the present invention, the renewal SMBIOS data structure tables comprise the following steps：
Step S201, finds the memory address location where SMBIOS data structure tables；
Step S202, the memory address space of SMBIOS data structure tables is unlocked, and data structure table can be changed；
Step S203, according to the Type types for the SMBIOS data structure tables to be updated, scans in data structure table, looks forTo this Type type structure tables position, the static information just set up is updated into this Type tables of data；
Step S204, finds next Type type data structure tables to be updated, continue to update, until renewal in needType type data structure tables.
As a further improvement on the present invention, in addition to step S205, after renewal is finished, by the internal memory of data structure tableLocation space is pinned, and prevents from being changed by mistake.
As a further improvement on the present invention, in step S2, SMBUS controllers according to the SMBUS addresses of EEPROM device,Communication is set up, if although feedback does not find that EEPROM device or discovering device obtain complete machine mark and actual complete machine markKnow unmatched result, then end operation.
Compared with prior art, beneficial effects of the present invention are：
Using technical scheme, by setting EEPROM in backboard, and cabinet and mainboard are connected, set up logicalLetter, recognizes machine system, and automatic modification can be also carried out to static information and is updated, and makes whole SMBIOS data structure tables all in canModification state；A bios software is only needed to, just all machine systems corresponding to same money mainboard can be applicable, be provided for systemAccurate SMBIOS information；Hardware information can only be collected and then update in start process originally by solving prior art BIOSSMBIOS multidate informations, the problem of static information can not be changed.
