Summary:The present application discloses a processing method for a brute force hot unplug operation on a U.2 NVMe solid-state disk, including: predefining a short signal pin for detecting whether an NVMe solid-state disk is in place; presetting to trigger an operation of calling a SMI program according to input state change information of GPIO of a PCH chip, where an input state value of the GPIO is determined according to a connection state of the short signal pin and a U.2 slot; calling the SMI program when a change in an input state of the GPIO is detected, and reading the input state value of the GPIO; and breaking a link between a PCIe root bridge and the NVMe solid-state disk by using the SMI program if the input state value of the GPIO is a corresponding value about the NVMe solid-state disk not in place.
