Abstract: A computing device adapted to a server having a baseboard management controller. The computing device includes a first inter-integrated circuit (I2C) bus, a storage unit, a second I2C bus, and a first register. The first I2C is configured to connect to the baseboard management controller. The storage unit is connected to the first I2C and configured to store firmware data of the computing device. The second I2C is configured to connect to the baseboard management controller. The first register is connected to the second I2C and a first set of general-purpose input/output (GPIO) pins. The first register is configured to obtain and store a first status message of a first system device through the GPIO pins. The baseboard management controller programs the firmware data into the storage unit through the first I2C, and read the first status message through the second I2C.
