During concrete enforcement realizes, described BIOS image file can be stored directly in BMC's
In first storage medium, then when obtaining described BIOS image file, straight by baseboard management controller BMC
Connect the BIOS image file read in storage medium, then be sent out by interface, but in order to enter
One step reduces the amount of storage of file and avoids causing BIOS successfully to add during BIOS image file fault
Carry problem, the present embodiment on the basis of embodiment one to BIOS image file acquisition side of the present invention
Method has carried out further improvement:
As in figure 2 it is shown, the BIOS image file acquisition methods described in the present embodiment comprises the following steps:
Step S210: the interface BIOS of baseboard management controller loads instruction；
Step S220: described BIOS is loaded instruction and is forwarded to the processor of baseboard management controller by interface;
Step S230: after described processor receives described BIOS loading instruction, from baseboard management controller
Storage medium obtains BIOS image file；
Step S240: described processor sends described BIOS image file by described interface.
Wherein, described step S230 includes again step S231, step S232 and step S233;Concrete,
Described step S231 is that described processor reads second storage Jie being positioned at described baseboard management controller
BIOS mirror image compressed file in matter；Described second memory mechanism is non-volatile memory medium；
Described step S232 is that described BIOS mirror image compressed file is decompressed as BIOS mirror image by described processor
File is also stored in described first storage medium；
Described step S233 is that described processor reads BIOS image file from the first storage medium.
Described non-volatile memory medium is that system power supply disconnects, and the storage medium that data will not be lost is concrete
Can be any in flash memory, electrically rewritable storage medium and ROM (read only memory)；After decompression
BIOS image file is still stored in the storage medium of described baseboard management controller.
When described baseboard management controller BMC only includes the first storage medium, the most described first storage is situated between
Matter is non-volatile storage medium, and that concrete can be ROM；Storage can be BIOS image file
Maybe can generate the alternative document of BIOS image file, the compressed file of concrete BIOS image file；
BIOS image file is being obtained by decompression；
When described baseboard management controller BMC includes the first storage medium and the second storage medium, then
First storage medium can be non-volatile storage medium such as ROM, it is possible to be the storage medium of volatibility
Such as RAM；If the first storage medium is non-volatile storage medium, that can directly store is BIOS
Image file；If the first storage medium is the storage medium of volatibility, then the second storage medium is non-volatile
Storage medium；In second storage medium, storage can be BIOS mirror image compressed file or BIOS mirror image
