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 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.

Abstract: A communication interface adapter is provided to include a first communication interface to be electrically connected to a computer device, a second communication interface to be electrically connected to the peripheral device, a microcontroller, a communication interface hub electrically connected to the first communication interface and the microcontroller, and a switch unit electrically connected between the communication interface hub and the second communication interface. The switch unit is controlled by the microcontroller to make or break connection between the communication interface hub and the second communication interface.
