Structure and method for supporting BMC flash change during startup of server

The invention particularly relates to a structure and method for supporting BMC flash change during startup of a server. The structure comprises a BMC, a signal control chip and a flash slot, whereinthe BMC is connected with the flash slot through a signal control switch; a power supply is connected with the flash slot through a power control switch; the signal control chip is connected with a control end of the signal control switch, a control end of the power control switch and a reset signal end of the BMC; and anti-static circuits are connected between the signal control switch and the flash slot and between the power control switch and the flash slot. According to the structure and server for supporting BMC flash change during startup of the server, the direct change of a flash chipis realized under the startup state of the server, and the problems that the flash chip is damaged by static electricity and data in the flash chip is disordered as the flash chip is changed is avoided at the same time, thereb
