Detailed Description
The embodiment of the invention provides a switching method of a BIOS chip and a substrate management controller, which are used for quickly solving the problem that a server system cannot be started due to the fault of the BIOS chip.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the BIOS startup process, a BMC (Baseboard Management Controller) sets two monitoring points to the BIOS startup process, where the first monitoring point is the early stage of the BIOS startup, the BMC starts to time after detecting a system startup signal, and if a startup start signal sent by the BIOS is not received within a certain time, for example, about 5 seconds, the BMC considers that the startup BIOS chip cannot normally start the system, so as to automatically switch the BIOS chip to a redundant chip. The second monitoring point is the later stage of system startup, when the first monitoring point signal is received, the timer is re-timed, and after a period of time, for example, the signal that the BIOS is started up cannot be received by the BMC within 10 minutes after the first signal is received, so that the BMC considers that the BIOS cannot normally start up the system, automatically switches the BIOS chip to the redundant chip, and starts up the system again. The signals for the BIOS to communicate with the BMC may be changed in state by GPIO (General Purpose Input/Output) or may be sent to the BMC in a series of manners such as sending a log.
Two BIOS chips are installed on the server, and BIOS programs capable of being started are burnt. By the method for monitoring the BIOS starting signal through the BMC, when one BIOS chip cannot be normally started, the BIOS chip is automatically switched to the redundant BIOS chip for starting, so that the time for manual detection and manual switching of the BIOS is shortened, and the problem that a server cannot be started is automatically and quickly solved.
Referring to fig. 1, fig. 1 is a schematic diagram of an embodiment of a switching method of a BIOS chip according to an embodiment of the present invention, including:
101. the BMC receives the operation instruction.

102. The BMC monitors whether a first signal sent by the first BIOS chip is received within a first time period and whether a second signal sent by the first BIOS chip is received within a second time period, if the BMC does not receive the first signal within the first time period or the BMC does not receive the second signal within the second time period, step 103 is executed, and if the BMC receives the first signal within the first time period and the BMC receives the second signal within the second time period, step 104 is executed.
In this embodiment, the BMC may monitor whether a first signal sent by the first BIOS chip is received within a first duration in real time, and monitor whether a second signal sent by the first BIOS chip is received within a second duration, where the first duration and the second duration are different durations, and the second duration is a duration after the first duration, and the specific first duration may be less than the second duration. That is, the BMC may monitor in real time whether the signal sent by the first BIOS chip is received within the first duration and the second duration, and if the BMC receives the first start signal (i.e., the signal for starting the server) sent by the first BIOS chip within the first duration, for example, within about 5 seconds, no operation is performed. If the first signal is not received, step 103 is executed, and after receiving the first signal, the BMC counts again, and if the BMC does not receive the second signal (i.e., the signal that the start of the server is completed) sent by the first BIOS chip, that is, the second signal, within a second duration, for example, 10 minutes, step 103 is also executed.
When it needs to be described, when monitoring whether a first signal sent by a first BIOS chip is received by the BMC within a first time period and whether a second signal sent by the first BIOS chip is received within a second time period, the BMC may determine whether the first signal is received within the first time period and whether the second signal is received within the second time period by monitoring a state change of a General Purpose Input/Output (GPIO) between the first time period and the first BIOS chip; similarly, the BMC may also monitor a log sent between the first time duration and the first BIOS chip to determine whether the first signal is received in the first time duration, and whether the BMC receives the second signal in the second time duration, which may be determined in other manners, and the two manners are described as examples, and are not limited specifically.
103. The BMC switches the first BIOS chip into a second BIOS chip to restart the server.
In this embodiment, when the BMC does not receive the first signal within the first duration or does not receive the second signal within the second duration, the boot chip of the server is switched from the first BIOS chip to the second BIOS chip to reboot the server.
104. The BMC determines that the server boot is complete.
In this embodiment, when the BMC receives the first signal within the first time period and the BMC receives the second signal within the second time period, it is determined that the server is normally started.
In summary, in the embodiment of the present invention, the second BIOS chip and the second BIOS chip are set in the server, and two monitoring points are set for the BIOS chip: the starting and the starting are completed to monitor the two monitoring points, whether the BIOS chip can be normally started or not is automatically detected, and the BIOS chip is automatically switched to the second BIOS chip under the condition that the first BIOS chip is abnormally started, so that the problem that a server system cannot be normally started is quickly solved, and manpower and material resources are saved.

or monitoring a sending log between the first time length and the first BIOS chip, and monitoring a sending log between the second time length and the first BIOS chip, so as to judge whether the first signal is received in the first time length, and whether the second signal is received in the second time length.
7. The BMC of claim 5 or 6, further comprising:
a determining unit, configured to determine that the server is started up when the first signal is received within the first duration and the second signal is received within the second duration.
8. The BMC of claim 5 or 6, wherein the first time period is less than the second time period.
9. A processor for executing a computer program, the computer program executing the steps of the method according to any of claims 1 to 4.
10. A computer-readable storage medium having stored thereon a computer program, characterized in that: the computer program when executed by a processor implementing the steps of the method according to any one of claims 1 to 4.
