Abstract
An operation method of a system platform includes steps of: transmitting, by an infrared receiver, a received infrared signal to a transmission interface; transmitting, by the transmission interface, an interrupt notification signal to an operation system power management agent (OSPM) through an advanced configuration and power interface (ACPI); receiving, by an infrared application program of an operating system, the interrupt notification signal from the OSPM, so as to generate a system management interrupt (SMI) in a universal extensible firmware interface (UEFI) basic input output system (BIOS) to execute a system management mode (SMM) program; and executing, by the UEFI BIOS, a decoding driver program, and receiving the infrared signal from the transmission interface, so as to decode the infrared signal into event data, and store the event data in a storage device.
