Abstract: A method of updating a firmware of a computer including a motherboard that has a BMC and a first CPLD, and a backplane that has a second CPLD having a flash memory. The method including steps of: the first CPLD changing a logical value of a signal when the first CPLD determines that a power of the computer is in a desired range; the BMC receiving the signal, and being initiated once the logical value of the signal has been changed; when the BMC is to update a firmware of the second CPLD, the BMC changing a logical value of a register of the first CPLD; and when the first CPLD determines that the logical value of the register has been changed, the first CPLD decoding and verifying a firmware code that is received from the BMC, and updating the firmware code thus decoded and verified to the flash memory.
