This invention relates to the field of server order firmware version management, specifically disclosing a method, device, terminal, and medium for server order firmware version management. When the entire machine is powered on and testing begins, the system acquires the order placement time, the latest firmware release time, and the order test start time. It then determines whether the order placement time is later than the latest firmware release time; if so, the order is considered a new order; otherwise, it determines whether the order test start time is later than the latest firmware release time; if so, the order is considered a new order; otherwise, it is considered a last order. If it is a new order, the latest firmware is used for firmware update management during the entire machine test; if it is a last order, the old firmware is retrieved for firmware update management during the entire machine test. This invention intelligently identifies the firmware to be updated during the entire machine power-on test using timestamp information, achieving intelligent switching of firmware upgrade imports from the entire machine factory, eliminating the need for manual processing of each order, reducing manpower, and lowering the risk of omissions.
