Description
Technical field
The present invention relates to server field, it is specifically a kind of update after BIOS the method that is not updated of DMI synchronizing information and
System, for after updating BIOS DMI synchronizing information be not updated.
Background technique
The chief component of DMI (Desktop Management Interface, Desktop Management Interface) is
Management InformationFormat (MIF) database.This database includes all in relation to computer system and matching
The information of part.By DMI, the available sequence number of user, manufacturer computer, Serial Port Information and other system accessories information.DMI
The collection of information must strictly in accordance with SMBIOS (System Management BIOS, SMBIOS) specification under the premise of into
Row.
EEPROM (Electrically Erasable Programmable read only memory), band electrically erasable
The storage chip that data are not lost after a kind of programmable read only memory -- power down.EEPROM can on computers or dedicated be set
Standby upper wipe has information, reprograms.It is commonly used in plug and play.
FRU(Field Replaceable Unit, Field Replaceable Unit), it includes Chassis, Board and
The fields such as Product, each field respectively correspond to different information, specifically include manufacturer server, server ID number, clothes
Device asset number, the server date of production, server be engaged in Host equipment room etc., therefore whether the FRU information of server keeps
It is constant that there is related important function for server in machine room updating maintenance.
Usually, DMI information is present in server HOST main system, FRU information preservation is in server B MC system
In.For the ease of system administration, configuration information in general DMI is synchronous with FRU information.But in actual use process

Wherein, each field (including each field name and its corresponding field value) of DMI is stored in server HOST
In main system.
It should be noted that each field of DMI involved in the present invention is read from server HOST main system, tool
Body can be selected correlation technique any in the prior art and be read out.
In addition, the method not being updated with DMI synchronizing information after above-mentioned update BIOS is correspondingly, the present invention also provides
A kind of system for not being updated of DMI synchronizing information after updating BIOS, including the first synchronization unit, the second synchronization unit and EEPROM
Storage unit.Wherein: the first synchronization unit is used in BIOS start-up course, according to DMI field predetermined and FRU word
The corresponding relationship of section, by the field value of the synchronous FRU of the present field value of DMI.Second synchronization unit, for completing to update in BIOS
Afterwards in restarting procedure, according to the corresponding relationship of the DMI field and FRU field predetermined, by the current word of DMI
The field value of the synchronous FRU of segment value.EEPROM memory cell, using EEPROM storage chip, with first synchronization unit and
Second synchronization unit is connected, for storing the field and its field value of the FRU.
In use, in BIOS start-up course, by the first synchronization unit according to DMI field predetermined and FRU word
The corresponding relationship of section, by the field value of the synchronous FRU of the present field value of DMI；After BIOS completes to update in restarting procedure,
According to the corresponding relationship of the DMI field and FRU field predetermined, by the field of the synchronous FRU of the present field value of DMI
Value.
In the present embodiment, the EEPROM memory cell is also stored with the mapping table pre-established, described
The corresponding relationship of DMI field and FRU field predetermined corresponding be stored in the mapping table.Correspondence is described right
Answer a kind of embodiment of relation table as shown in Figure 3.Wherein in a table as shown in figure 3, each DMI field predetermined and its
In the corresponding corresponding same record row being stored in Fig. 3 of corresponding FRU field.Such as in table shown in Fig. 3 serial number 1 note
In record row, there is the Manufacturer field of DMI predetermined opposite with the Product Manufacturer field of FRU
It answers；For another example in table shown in Fig. 3 in the record row of serial number 2, the Product Name field of DMI predetermined and FRU's
Product Name field is corresponding.Wherein in table shown in Fig. 3: the corresponding DMI field of the record row of serial number 1-5 is DMI
System Information relevant field, serial number 6-10 the corresponding DMI field of record row be DMI Base Board
The Chassis for recording the corresponding DMI field of row and being DMI of Information relevant field, serial number 11-15
Information relevant field.
