Abstract:
1. A method of fail safe flashing a management device of a computer system, the management device comprising a volatile memory and a non-volatile memory, wherein the non-volatile memory is a flash memory, and wherein the non-volatile memory stores a current firmware, a backup critical information, and an actual critical information, the method comprising: launching a flasher module to operate the management device in a flash mode; copying the actual critical information from the non-volatile memory to the volatile memory, and erasing the actual critical information stored in the non-volatile memory; upgrading the current firmware by a replacement firmware received from a remote computing device; mixing and matching the actual critical information with a new critical information; requesting a user input to write the mixed and matched critical information back to the non-volatile memory as the actual critical information; writing the mixed and matched critical information back to the non-volatile memory as the actual critical information when the user input is not received after a first predetermined time period; and restarting the management device in a booting mode, wherein the backup critical information is read-only in the flash mode and rewritable in the booting mode; and wherein the step of restarting the management device in a booting mode comprises:
