Abstract: A method of remotely modifying a basic input/output system (BIOS) configuration setting includes steps of: transmitting, by a remote computer, a modification instruction to a cloud server; transmitting, by the cloud server to a POS system, a new configuration value of the BIOS configuration setting contained in the modification instruction; determining, by an embedded controller of the POS system, whether the new configuration value is identical to an original configuration value of the BIOS configuration setting; and by the embedded controller when a result of the determination is negative, updating the BIOS configuration setting and transmitting a response instruction to the remote computer.

Abstract: A system includes a switch unit that is connected to a host connector of a computer, an embedded controller (EC) that connected to the switch unit, and a management device that includes a device connector and a microcontroller. The device connector is connected to the host connector. The microcontroller is connected to the device connector, and sends external data via the device connector to the EC. When the EC is supplied with electricity, the EC controls the switch unit to establish an electrical connection between the EC and the host connector so as to allow the EC to communicate with the microcontroller through the EC and the host connector to receive the external data from the microcontroller.

Abstract: A computer program product embodied on a non-transitory computer readable medium of a control system includes a firmware program file, a signature detection module that causes a processor to detect whether a pre-defined signature is present; a booting module that causes the processor to perform, after it is determined that the pre-defined signature is not present in the main block, operations of power management and pin initiation included in the booting sequence; and a flashing module that causes the processor to perform, in response to receipt of a flashing command, a flashing operation that includes overwriting the firmware program file with an update firmware program file.
