Title: Method for restoring system configuration information of a network attached storage

Abstract: A method for restoring system configuration information of a network attached storage includes the steps of: setting system configuration information of an network attached storage as a backup file; registering an interrupt handler; pressing down an input key (16) to turn off a power switch (K1) and generate an interrupt signal; invoking the interrupt handler to process the interrupt signal and returning interrupt GPIO information; determining whether an operating system receives the interrupt GPIO information from the interrupt handler; sending a periodical voltage to a second pin (P2) for blinking a LED (L1) if the operating system receives the interrupt GPIO information from the interrupt handler; invoking the backup file to restore the system configuration information of the network attached storage; and sending a high voltage command to the second pin for powering off the LED, which indicates that the system configuration information has been restored.
