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 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.
