The application provides a
system, method and device for clearing
CMOS settings on a domestic
Feiteng platform, belonging to the technical field of
CMOS setting clearing, and the
system comprises an MCU, a BMC, a CPU, a first Flash
chip, a second Flash
chip, a button
cell and a
server mainboard power supply; the CPU is connected with a first
chip selection switch, and the first chip selection switch is connected with the first Flash chip, the second Flash chip and the MCU; the BMC is connected with a second chip selection switch, and the second chip selection switch is connected with the first Flash chip and the second Flash chip; the MCU is connected with the button
cell, the
server mainboard power supply and the BMC, and the MCU is further connected with a power-on button and a short-circuit PIN. In the case of
AC power failure, the application restores the factory settings of the
BIOS firmware through the
backup Flash chip, reduces the risk of human operation, reduces the loss, and improves the maintenance convenience.
