Embodiment
BIOS method for refreshing of the present invention and system are used for an object computer 1 is carried out refreshing of BIOS, described BIOS method for refreshing and system carry out the BIOS refresh operation by the master control computer 3 that stores the BIOS refreshing file to described object computer 1, and described master control computer 3 is to realize communicating with one another by USB (Universal Serial BUS, USB (universal serial bus)) data bridge cable 2 with described object computer 1.
As shown in Figure 1, be the Organization Chart of BIOS updating system of the present invention preferred embodiment.
As shown in Figure 2, be the functional block diagram of BIOS updating system of the present invention preferred embodiment.
Described BIOS updating system 10 comprises structure module 100, detecting module 101, read module 102 and refresh module 103.The function of each module will describe in detail in conjunction with the process flow diagram of Fig. 3.
As shown in Figure 3, be the process flow diagram of BIOS method for refreshing of the present invention preferred embodiment.
Step S10, described structure module 100 enters the SHELL environment in object computer 1 (this SHELL environment is operating system and outside topmost interface, be the outmost one deck of operating system, mutual between SHELL leading subscriber and the operating system), and make up virtual hard disk.
The step that described structure module 100 makes up virtual hard disk is as follows: load hard drive, the load document system enters the virtual hard disk under the SHELL environment.Above step because the virtual hard disk technology is prior art, makes up principle so no longer specifically introduce it for making up the step of virtual hard disk.
Step S12, whether described detecting module 101 detecting master control computers 3 have sent the BIOS refreshing file to a USB controller 11 of object computer 1, when master control computer 3 has sent the BIOS refreshing file to a USB controller 11 of object computer 1, and execution in step S14, otherwise, return and continue detecting.
Detecting process in this step is as follows: whether detecting module 101 detectings the one USB controller 11 receives the BIOS refreshing file, when a USB controller 11 receives the BIOS refreshing file, detecting module 101 judges that master control computer 3 has sent the BIOS refreshing file to a USB controller 11 of object computer 1, otherwise detecting module 101 judges that master control computer 3 does not send the BIOS refreshing file to a USB controller 11 of object computer 1.
Master control computer 3 sends the BIOS refreshing file to the process of object computer 1, will describe in detail in Fig. 4.
Step S14, described read module 102 reads to internal memory 12 with the BIOS refreshing file from the buffer zone of a USB controller 11.
Step S16, described refresh module 103 writes virtual hard disk with the BIOS refreshing file in the internal memory 12, and utilizes the BIOS updating software to carry out refreshing of BIOS in virtual hard disk.
In this step, when refresh module 103 will utilize the BIOS updating software to carry out the refresh operation of BIOS, should guarantee to store the BIOS refreshing file in the file read-write position of virtual hard disk.When refresh module 103 writes virtual hard disk with the BIOS refreshing file, exactly the BIOS refreshing file is write the file read-write position of virtual hard disk.
Need to prove that therefore described BIOS method for refreshing and system need will guarantee that the BIOS updating software can be performed with BIOS updating software complete operation.If object computer 1 can't normal boot-strap before operation, then this BIOS method for refreshing and system are inapplicable.
As shown in Figure 4, be that the master control computer transmission BIOS refreshing file of BIOS method for refreshing of the present invention preferred embodiment is to the process flow diagram of object computer.
Step S120, master control computer 3 obtain the BIOS refreshing file from hard disk 30.
Step S121, master control computer 3 call the USB driver this BIOS refreshing file that gets access to are sent to the 2nd USB controller 31.
Step S122, described the 2nd USB controller 31 is sent to usb data bridge cable 2 with this BIOS refreshing file.
Step S123, described usb data bridge cable 2 is sent to a USB controller 11 with this BIOS refreshing file.
Need to prove the stationkeeping of described BIOS refreshing file.When master control computer 3 needed to send the BIOS refreshing file to object computer 1, this master control computer 3 produced a BIOS refreshing file with the BIOS source code through the compilation tool compiling, and this BIOS refreshing file is stored in the hard disk 30 of master control computer 3.
BIOS method for refreshing of the present invention and system are connected with object computer 1 described master control computer 3 earlier by usb data bridge cable 2; Master control computer 3 reads the BIOS refreshing file, and this BIOS refreshing file is sent to object computer 1 by usb data bridge cable 2; Object computer 1 receives this BIOS refreshing file, thereby realizes the BIOS refresh operation to object computer 1.The present invention also utilizes the virtual hard disk technology, a virtual hard disk on object computer 1, and then finish the refresh operation of BIOS.The present invention does not need the auxiliary of movable storage devices such as CD, USB flash disk in carrying out the process that BIOS refreshes, the cost-effective while, can realize that BIOS refreshes under not by the situation of External memory equipment.Because usb data bridge cable 2 has been a kind of very ripe interfacing, be easy to realize; And the volume of transmitted data of usb data bridge cable 2 is big, data transfer rate is fast, has improved the efficient that BIOS refreshes.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
