BMC, execution server remote management controller, english name Baseboard Management controller. The method can perform firmware upgrade, check machine equipment and other operations on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller and RAM for data storage, flash memory for non-volatile data storage, and firmware to provide basic remote manageability in terms of secure remote reboot, secure re-power-up, LAN alerting, and system health monitoring. In addition to the basic IPMI and system operation monitoring functions, the mBMC can also enable BIOS flash element selection and protection by storing the previous BIOS using one of the 2 flash memories. For example, when the system fails to boot after a remote BIOS upgrade, the remote administrator may switch back to the previously-working BIOS image to boot the system. Once BIOS is upgraded, the BIOS image can be locked, so as to effectively prevent virus from invading it.
