Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of BIOS initialization method, apparatus, equipment and computer readable storage medium, with
Realize the stability for improving BIOS.
Referring to Fig. 1, a kind of BIOS initialization method provided in an embodiment of the present invention, which comprises
S101, the starting state that BIOS chip operational objective described in process detection starts mirror image is monitored by IPMI；Wherein,
At least two starting mirror image of storage in BIOS chip；
Specifically, IPMI (Intelligent Platform Management Interface) is Intelligent Platform pipe
The abbreviation for managing interface is a kind of industry mark for managing the use of peripheral equipment used in the business system based on Intel structure
It is quasi-.IPMI can provide standard commands and OEM order management control system and hardware device, such as temperature, voltage, fan work shape
State, power supply status etc., it is easy to use when needing to operate machine large batch of in computer room.As can be seen that as service
Monitoring management tool on device, IPMI protocol are applied to monitoring management software and hardware information, and provide unified, pond interface
To outside, it is more convenient for managing.Therefore this BIOS redundancy scheme based on IPMI protocol design that this programme proposes, is compared to
It is a kind of feasible and convenient and fast scheme for current other technologies.
This programme needs to guarantee to store at least two starting mirrors in BIOS chip to realize to the switching of starting mirror image
Picture is known as target start mirror image for the starting mirror image run first in S101；Therefore, it is in power-up state in system,
There are at least two starting mirror images in BIOS chip, and when IPMI process normal operation, if triggering power-on operation,
IPMI process can create monitoring thread after detecting system boot, pass through the monitoring thread real-time monitoring BIOS operating status.
Wherein, starting state includes abnormality and normal condition, and under abnormality, operating system is unable to normal boot-strap, and just
In normal situation, system can normal boot-strap.
If S102, detecting that starting state is abnormality, switching removes the target start from the BIOS chip
Other starting mirror images except mirror image, re-execute initialization operation.
It should be noted that the quantity of the starting mirror image in BIOS chip is at least two, that is to say, that start mirror image
Quantity can be two, or be greater than two；Therefore, when it is abnormal for detecting starting state, time of the handover operation of execution
Number is starting mirror image quantity -1, such as: if the quantity of starting mirror image is two, then IPMI process cuts BIOS starting mirror image
Changing operation at most only will do it once, and system will be unable to normally start when switching times are greater than 1, because switching times are more than one
When, show that two BIOS mirror images are all destroyed, machine can not normally start in this state.
As can be seen that this method based on IPMI switching BIOS starting mirror image that this programme proposes, when one of them is opened
When index glass picture breaks down during startup, another starting mirror image that can switch BIOS by IPMI order is restarted, from
And restore system from exception；Also, since this programme is realized based on IPMI protocol, so with other BIOS redundancy schemes
It compares, this programme design is more simple and more easy to maintain.
Referring to fig. 2, another BIOS initialization method provided in an embodiment of the present invention, which comprises
If S11, the IPMI monitor process detection to system boot, judge from the first scheduled duration after system boot
It is interior, if to receive the first receipt signal that the BIOS chip is sent；
If being not received by, S12 is executed；If receiving, S13 is executed；
S12, the starting state for determining the BIOS chip operational objective starting mirror image are abnormality, and continue to execute
S15；
Specifically, creating IPMI monitoring process just after system boot to be monitored to starting state；BIOS starts to hold
Row initialization operation, under normal condition, when BIOS chip runs the first scheduled duration by target start mirror image, just to IPMI into
Journey sends a receipt signal, for showing that BIOS starting at this time is normal；If being not received by receipt in the first scheduled duration
Signal then illustrates that starting state is abnormality, and executes S15；If receiving receipt signal, continue to monitor.
S13, judge out of, the second scheduled duration that receive the first receipt signal, if receive the BIOS core
The second receipt signal that piece is sent；
If being not received by, the S12 is executed；If receiving, S14 is executed；
S14, the starting state for determining the BIOS chip operational objective starting mirror image are normal condition；
It should be noted that under normal circumstances, understand after completing CPU and various hardware initializations after BIOS starting, then
It is secondary to send receipt signal to IPMI process；If IPMI monitoring process receives receipt signal, illustrate that initialization operation executes
Success；If IPMI monitoring process is not received by receipt signal in the second scheduled duration, illustrate that starting state is abnormal
State, and execute S15.
It is understood that the first scheduled duration and the second scheduled duration in this programme can voluntarily be set according to demand
It is fixed, such as: settable first scheduled duration is 5 seconds, and the second scheduled duration of setting is 20 minutes；It should be noted that in addition to this
Starting state described in embodiment determines except method, can also determine starting state by other means, such as: setting
BIOS only sends a receipt signal to IPMI monitoring process, that is to say, that only after BIOS initialization success, just supervises to IPMI
Survey process sends receipt signal, although this mode also may be implemented the monitoring to BIOS starting state, the waiting time compared with
It is long, by taking the second scheduled duration is 20 minutes as an example, if BIOS sends receipt signal twice, it was not received by 5 seconds
Receipt signal can execute S15-S16；If BIOS sends a receipt signal, need not receive in 20 minutes
When to receipt signal, S15-S16 just can be performed.
S15, determine that the code name of other starting mirror images in the BIOS chip in addition to the target start mirror image identifies；
S16, the EEPROM that the code name is identified to write-in mirror image switch chip, so that the BIOS chip is turning back on
Afterwards, corresponding starting mirror image is read by the code name that stores in EEPROM mark, re-executes initialization operation, and will be with
The code name identifies corresponding starting mirror image as target start mirror image, continues to execute the S11.Wherein, the mirror image switch
Chip is CY8C9 chip.
In the present solution, IPMI process can control hardware shutdown at this time, then switch if starting state is abnormality
BIOS starts mirror image to another, then turns back on, continues to execute initialization operation, and continue to execute S11, monitoring starting shape
State.
Also, this programme, can be by IPMI Process flowchart mirror image switch chip to BIOS's when executing handover operation
Starting mirror image is selected；The mirror image switch chip is specially the CY8C9 chip of programmable systemonchip PsoC, in we
In case, mirror image switch chip is not defined, as long as the mirror image switch chip can interact with BIOS and interior set memory, energy
Realize the switching to mirror image.In the present embodiment, it is only illustrated so that mirror image switch chip is CY8C9 chip as an example.
In the present solution, each starting mirror image in BIOS chip is corresponding with a code name mark, therefore, pass through
When CY8C9 chip executes mirror image switch operation, it is necessary first to which into the EEPROM of the chip, filling enables the code name mark of mirror image；
It is by the benefit that EEPROM is written in mirror image code name: will not be lost after currently needing the code name mark power-off of starting mirror image to be applied
It loses, even if power operation occurs, when being switched on again, BIOS still can read the code name mark of starting mirror image from the EEPROM of chip
Know, boots up operation by other starting mirror images.
As can be seen that this programme by IPMI process monitoring BIOS initialization starting state, if detecting that BIOS is opened
When dynamic abnormal, then switch the starting mirror image of BIOS, to realize the redundancy scheme of BIOS, avoiding the occurrence of operating system cannot be just
The phenomenon that normally opened machine.
