The BIOS image file: the program of Basic Input or Output System (BIOS) operation guiding is for computing machine provides the program of direct hardware controls of lowermost level, has realized the loading of BIOS, could further carry out the startup of system.
In the described BIOS image file of the present embodiment acquisition methods, from the first storage medium of BMC, obtain, thereby store as can be known the spanned file of BIOS image file or BIOS image file among the BMC, thereby reduced the application that is used for storage SPI Flash, thereby taken full advantage of the storage medium of BMC, reduced SPI Flash, thereby reduced system overhead, save hardware cost, simplified the structure of system, be conducive to the integrated and miniaturization of system.
Embodiment two:
In concrete enforcement implementation procedure, described BIOS image file can directly be stored in the first storage medium of BMC, when then obtaining described BIOS image file, directly read BIOS image file in the storage medium by baseboard management controller BMC, outwards send by interface again and get final product, but the problem that causes BIOS successfully to load in order further to reduce the memory space of file and to avoid BIOS image file fault, the present embodiment has carried out further improvement on the basis of embodiment one to BIOS image file acquisition methods of the present invention:
As shown in Figure 2, the described BIOS image file of the present embodiment acquisition methods may further comprise the steps:
Step S210: the interface of baseboard management controller receives the BIOS load instructions;
Step S220: interface is forwarded to described BIOS load instructions the processor of baseboard management controller;
Step S230: after described processor is received described BIOS load instructions, from the storage medium of baseboard management controller, obtain the BIOS image file;
Step S240: described processor sends described BIOS image file by described interface.
Wherein, described step S230 comprises again step S231, step S232 and step S233; Concrete,
Described step S231 is the BIOS mirror image compressed file that described processor reads the second storage medium that is arranged in described baseboard management controller; Described the second memory mechanism is non-volatile memory medium;
Described step S232 is that described processor is the BIOS image file with described BIOS mirror image compressed file decompress(ion) and is stored in described the first storage medium;
Described step S233 is that described processor reads the BIOS image file from the first storage medium.
Described non-volatile memory medium is that system power supply disconnects, the storage medium that data can not be lost, and concrete can be any among flash memory, electrically rewritable storage medium and the ROM (ROM (read-only memory)); BIOS image file behind the decompress(ion) still is stored in the storage medium of described baseboard management controller.
When described baseboard management controller BMC only comprised the first storage medium, then described the first storage medium was non-volatile storage medium, and that concrete can be ROM; What store can be the alternative document that the BIOS image file maybe can generate the BIOS image file, the compressed file of concrete BIOS image file; Obtaining the BIOS image file by decompress(ion);
When described baseboard management controller BMC comprised the first storage medium and the second storage medium, then the first storage medium can be non-volatile storage medium such as ROM, also storage medium such as the RAM of volatibility; If the first storage medium is non-volatile storage medium, what can directly store is the BIOS image file; If the first storage medium is the storage medium of volatibility, then the second storage medium is non-volatile storage medium; What store in the second storage medium can be BIOS mirror image compressed file or BIOS image file; The second storage medium is used for storage BIOS mirror image compressed file or BIOS image file; BIOS image file or direct storage that described the first storage medium stores is used for the generation of storage BIOS mirror image compressed file turn the BIOS image file that copies from the second storage medium.
And what store in described baseboard management controller in the present embodiment is BIOS mirror image compressed file, memory space after the compression of BIOS image file is very little, be generally about 1M, thereby the storage space of the baseboard management controller that occupies is little, thereby can be because of the execution that affects other original functions of BMC.And with respect to traditional SPI Flash the inside that the BIOS image file directly is stored in, because what write is BIOS image file itself, BIOS image file itself is large compared to BIOS mirror image compressed file, it is also high thereby wrong probability to occur, if the BIOS image file error probability of storage is high, the unsuccessful probability that directly causes BIOS to load is risen, so the described BIOS image file of the present embodiment acquisition methods, because the BIOS mirror image compressed file of storage, thereby the problems referred to above have effectively been avoided, thereby promoted the success ratio of BIOS loading and the success ratio that system successfully starts, promoted user's experience.In this external traditional BIOS image file acquisition methods, directly from SPI Flash, read the BIOS image file, in case mistake appears in the BIOS image file, as suffer that the people is the destruction of BIOS refresh tool, then system just can't normally start, and store in the present embodiment BIOS mirror image compressed file, when the BIOS image file is destroyed, still can load the startup that BIOS reaches system by re-powering, thereby can be quick and easy reach reloading of BIOS, with respect to adopt two BIOS image files of two SPI Flash storages in order to prevent that the BIOS image file from being destroyed, or adopt BMC to store the loading method of the BIOS image file of two kinds of versions, need not in the present embodiment to adopt selector (such as CPLD:Complex Programmable Logic Device CPLD) when reloading, to select not destroyed BIOS, thereby again reduced hardware spending.In addition BIOS mirror image compressed file is stored in the non-volatile memory medium, be conducive to avoid the System Sudden power down, cause BIOS mirror image compressed file to be lost, cause BIOS to load and failure that system starts, thus raising again the stability that loads of BIOS.
In addition, because baseboard management controller BMC inside is integrated with processor, can realize the function of compressing, decompressing.Among the present embodiment and other embodiment that BIOS image file has been carried out compressing, used cleverly the processing power of BMC, when storing into again among the BMC after therefore can compressing the BIOS image file, thereby reduce taking of storage space, and storage space is less, and the possibility of the loss of data that is brought by the storage space fault is less.And in the prior art, the BIOS image file is stored among the SPI Flash, and SPI Flash is a kind of flash memory storage medium, and itself does not have processing capacity, can't carry out compression, decompression operation; In addition, when needs read the BIOS image file, the interface of SPI Flash was occupied, therefore also can't send out data and use outside processing unit execution decompression operation; If therefore the BIOS image file after the store compressed can't normally be read.
Embodiment three:
In concrete application process, usually need upgrading BIOS, the performance parameter of elevator system and increase new function and realize, therefore at the present embodiment on embodiment one and embodiment two described described BIOS image file acquisition methods bases, in order to realize that BIOS upgrades and further improvement is made in upgrading, concrete scheme is as follows:
Described BIOS image file acquisition methods also comprises:
Whether described processor detects the BIOS image file online needs to upgrade, and needs to upgrade then described processor down loading updating file and adds in the described BIOS mirror image compressed file when detecting.Thereby after baseboard management controller is opened, direct-detection upgrades then down loading updating to having, and add in the BIOS mirror image compressed file, when described interface receives the BIOS load instructions, what then processing was obtained is the BIOS image file that obtains according to the BIOS mirror image compressed file after upgrading, thereby has realized the optimization of systemic-function and the reparation of upgrading or some system risks or defective.Whether concrete online detection BIOS image file needs time of upgrading, and can arrange as required, usually can be arranged on the unlatching of baseboard management controller after.The flow process that concrete realization loads still is:
The interface of baseboard management controller receives the BIOS load instructions;
Interface is forwarded to described BIOS load instructions the processor of baseboard management controller;
After described processor is received described BIOS load instructions, from the second storage medium of baseboard management controller, read BIOS mirror image compressed file and at the first storage medium decompress(ion) of BMC, thereby obtain the BIOS image file, send described BIOS image file by described interface again.
When electronic equipment starts usually, started after the baseboard management controller BMC, could realize the loading to BIOS, and usually BMC's restarts the loading that is accompanied by BIOS, the flow process of the method that described BIOS image file obtains is, after BMC started, whether the processor of BMC detects needed to upgrade; Need to upgrade then down loading updating file, recompression is in BIOS mirror image compressed file, and decompress(ion) BIOS mirror image compressed file obtains the BIOS image file, is sending the BIOS loading position of described BIOS image file to appointment.Wherein, described BIOS load instructions dispensing device can be common South Bridge chip or Input/Output Control Center etc.; The concrete position of also usually having followed BIOS to load in the BIOS load instructions.
In the present embodiment, upgrade the easy renewal that has realized the BIOS image file by checking, how to judge whether the BIOS image file needs to upgrade, the common BIOS image file that can work as in the network has had can be for the version that upgrades, will be automatically with renewable sign or triggering message, send to for detection of application program or software or upgrade the medium method of device, concrete can upgrading with reference to existing BIOS detects, and just repeats no more at this.By the detection before loading, can realize easily the renewal upgrading of BIOS, thereby the function after the assurance system starts is upgraded and is optimized.
