s11: after the programmable logic device is powered on, the BIOS and the BMC are controlled to be powered on through the programmable logic device; and the power-on time of the BIOS is not later than that of the BMC.
After the server is powered on to enable the programmable logic device in the server to be powered on, the programmable logic device can be used for controlling the BIOS and the BMC to be powered on, so that the BIOS and the BMC can be powered on and started without locking a BIOS starting signal firstly to enable the BMC to be started preferentially, and the recovery time of the BIOS is shortened conveniently.
When the programmable logic device is used for controlling the power-on of the BIOS and the BMC, the BIOS and the BMC can be controlled to be powered on at the same time, so that the BIOS and the BMC can be powered on and started at the same time, or the BIOS can be controlled to be powered on preferentially to the BMC, so that the BIOS is powered on preferentially to the BMC, that is, the power-on time of the BIOS is not later than that of the BMC, the recovery time of the BIOS is shortened conveniently, and the recovery efficiency of the BIOS is improved.
S12: when the BIOS detects that the BIOS has errors or is tampered in the power-on starting process, the BIOS error flag bit is set.
The BIOS can detect whether the BIOS has errors or is tampered in the power-on starting process, and if the BIOS has errors or is tampered, the BIOS error zone bit can be set, so that the problem of the BIOS in the power-on starting process can be timely known through the BIOS error zone bit.
S13: reading the BIOS error zone bit through BMC, and starting the operating system kernel and reading and writing backup BIOS file service.
After the BIOS error flag is set, the BMC may obtain the BIOS error flag in an Input/Output (IO) mode during a power-on process, and start in a minimum mode after reading the BIOS error flag, that is, preferentially start a service related to BIOS recovery, specifically, start an operating system kernel (kernel) (specifically, an operating system kernel of the BMC itself), read a backup BIOS file, and write a backup BIOS file service (the start of the service is less than 1 minute), without waiting for the BMC to completely initialize and start all services in the BMC, so as to shorten the recovery time of the BIOS.
S14: and reading the backup BIOS file from the self storage block through the BMC, and writing the backup BIOS file into a BIOS chip so as to realize the recovery of the BIOS through the backup BIOS file.
After the BMC preferentially starts the service related to the BIOS recovery, the BMC can read the backup BIOS file from the self storage block, write the read backup BIOS file into the BIOS chip, shut down the BMC and automatically start the BIOS after the BIOS is recovered so as to realize the recovery of the BIOS.
As can be seen from the above, compared to the prior art in which the BIOS can be powered on to start detecting whether the BIOS is faulty after the BIOS power-on signal is locked after the BMC is completely initialized (the time spent on powering on the BIOS is more than 6 minutes), and the BIOS is recovered when the BIOS is faulty, the present application controls the BIOS and the BMC to be powered on simultaneously after the programmable logic device is powered on, and preferentially starts the service related to the BIOS recovery after the BMC reads the BIOS error flag (the time spent on reading the BIOS error flag is shorter than 1 minute) to perform the BIOS recovery, so that the present application can shorten the time spent on the BIOS recovery.
According to the technical scheme disclosed by the application, the BIOS and the BMC are controlled to be powered on simultaneously after the programmable logic device is powered on or the BIOS is controlled to be powered on earlier than the BMC, and when the BMC reads the BIOS error zone bit, the BIOS is recovered only by starting the kernel of the operating system and reading and writing the service of the backup BIOS file, namely the BIOS can be recovered without completely initializing the BMC, so that the recovery time of the BIOS can be shortened, the server can be rapidly recovered from the error state to the normal working state, and the performance of the server can be improved.
