Abstract
The embodiment of the invention discloses a method for controlling the starting of the BIOS (a basic input/output system) of an electronic device. The method comprises the following steps: after receiving a BIOS reading request from a processor, a controller decodes a BIOS reading request; the controller selects one memory region from at least two memory regions according to a decoding result to start the BIOS of the selected memory region; the controller detects the starting status of the BIOS of the selected memory region to judge whether the BIOS is successfully started; and when the BIOS of the selected memory region fails to be started, the controlling selects the other memory region from at least two memory regions to start the BIOS of the selected other memory region. When one BIOS fails to be started, the method can start the other selected BIOS without impacting the utilization of a user.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of control method, controller and control system of controlling BIOS start-up of electronic apparatus.
Background technology
BIOS (Basic Input Output System, Basic Input or Output System (BIOS)) is one group of program on a ROM (Read Only Memory, the ROM (read-only memory)) chip that is solidificated on the computer motherboard.Mainly comprise the most important basic input/output routine of computing machine, system information setting, startup power on self detection program and system start-up bootstrap routine etc.
BIOS suffers to destroy (computer virus destroys, and perhaps fails in the escalation process) then whole computer system and just can't guide, thereby cause whole computer system to use.At present, if the BIOS of computing machine is thoroughly destroyed, generally all be that the BIOS chip is taken off, use third-party programming tool (Flash programmable device etc.) that correct BIOS programming is entered then, and then be arranged to former computing machine and get on.This method is complicated operation not only, and needs extra instrument and relevant knowledge.Incompatibility general user's operation.For preventing that BIOS from being destroyed, some computer vendors has been used not scalable BIOS on mainboard, adopts the not reproducible firmware ROM that writes.
In realizing process of the present invention, the inventor finds that there is following problem at least in prior art:
Existing method BIOS is destroyed back (BIOS starts failure) and the BIOS chip need be taken off, the more complicated that operates, and need relevant professional knowledge and instrument, therefore be not easy to general user's operation.

Present embodiment is further comprising the steps of:
Present embodiment has the following advantages:
When BIOS starts failure, can select other BIOS to start, do not influence the user and use.
The embodiment of the invention two is a kind of control BIOS start-up of electronic apparatus systems, as shown in Figure 2, comprise controller 220, processor 210 and storer 230, storer 230 comprises at least two memory areas 231,232, at this is first memory zone 231 and second memory zone 232, and each memory area is used to store the bios program that the described electronic equipment of guiding starts, and processor 210 and storer 230 electrically connect by controller 220;
Please in the lump with reference to figure 3, controller 220 comprises:
Communication unit 221, the BIOS that is used for receiving processor 210 transmissions reads request;
Decoding selected cell 222, the described BIOS request of reading that is used for communication unit 221 is received is deciphered, from described two memory areas, select a memory area storer at least according to described decode results, can be storer 231 at this, start the BIOS in storer 231 zones of selecting;
State detection unit 223 is used to detect the storer 231 of selection or the BIOS starting state in 232 zones, judges whether described BIOS starts successful.
State detection unit 223 regularly detects described BIOS starting state.
Communication unit 221 starts under the situation of failure at the BIOS of the memory area of described selection, and to processor 210 transmission information, request processor 210 sends BIOS once more and reads request;
Decoding selected cell 222 receives after BIOS that described processor 210 sends once more reads request, the request of reading is deciphered to described BIOS, from described two memory areas, select another memory area at least according to decode results, start the BIOS of another memory area of described selection, can be storer 232 at this, start the BIOS in storer 232 zones of selecting.
Present embodiment has the following advantages:
When BIOS starts failure, use native system and controller and can select other BIOS to start, do not influence the user and use.
As shown in Figure 4, the embodiment of the invention three is a kind of BIOS control system, storer 330 specifically comprises at least two storage areas, and each storage area is a rom chip in the present embodiment, stores the bios program that the described electronic equipment of guiding starts in each rom chip respectively.At this, be example only, but do not represent storer 330 to only limit to two rom chips with two rom chips.Embodiment of the invention middle controller 320 is CPLD, and processor 310 is CPU, and storer 330 electrically connects by CPLD 320 with processor 310.
In the rom chip 330 of depositing BIOS, place two same bios programs.One is placed on rom chip address most significant digit is in 0 the storage space, to be referred to as BIOS 0; It is 1 place that another one is placed on the rom chip highest addresses, is referred to as BIOS 1.The highest addresses line of rom chip is by CPLD 320 control, can't help CPU 310 directly to control.During initial start-up, the reading command order of CPU 310 is after deciphering through north bridge chips, suppose that the address that provides is to add one 0 in most significant digit behind the Address_CPU.CPLD address decoding, pass to storer 330 then, so just choose BIOS 0 zone, start the BIOS in described BIOS 0 zone according to decode results.
If BIOS starts failure, then CPLD 320 sends repositioning information, and CPU210 resets.CPU210 sends BIOS again and reads request, and at this moment the address that provides of CPU210 still is Address_CPU.This time, after CPLD 320 decodings, add one 1, pass to rom chip 320 then, choose BIOS 1 zone, start the BIOS in described BIOS 1 zone according to decode results in most significant digit.Like this, when BIOS 0 because of certain reason when destroyed, system can start from BIOS 1 automatically, and need not manual intervention.
In the time of upgrading, by a software control upgrading BIOS 0 district, it is constant to keep BIOS 1 district.After the BIOS upgrading failure, still can clog-freely start like this.
The technical scheme of the embodiment of the invention has the following advantages:
This programme adopts a plurality of memory areas, each memory area is deposited a BIOS system respectively, utilize controller that described memory area is selected, prevent effectively that to reach BIOS is destroyed, effectively guiding BIOS upgrades, and when BIOS starts failure, can select other BIOS to start, not influence the user and use.
Through the above description of the embodiments, those skilled in the art can be well understood to the present invention and can realize by hardware, also can realize based on such understanding by the mode that software adds necessary general hardware platform, technical scheme of the present invention can embody with the form of software product, it (can be CD-ROM that this software product can be stored in a non-volatile memory medium, USB flash disk, portable hard drive etc.) in, comprise that some instructions are with so that a computer equipment (can be a personal computer, server, the perhaps network equipment etc.) carry out the described method of each embodiment of the present invention.
It will be appreciated by those skilled in the art that accompanying drawing is the synoptic diagram of a preferred embodiment, module in the accompanying drawing or flow process might not be that enforcement the present invention is necessary.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be looked protection scope of the present invention.
