Abstract: A booting method capable of executing a warm boot or a cold boot when a CPU crash occurs in a computer system having a CPU and a memory. First, when the CPU is in a crash state, it is detected that a user wants to execute a hardware reset function or a software reset function. Next, a hardware reset operation is executed to reboot the CPU. Then, when the user chooses to execute the hardware reset function, data and predefined values of the memory are deleted to make the computer system return to a default state. Thereafter, when the user chooses to execute the software reset function, the hardware reset operation is regarded as an operation to replace a software reset operation, and the computer system holds the data and predefined values to make the computer system return to a setting state before the computer system is crashed.

Abstract: A method for an HTML document to access local system resources, which receives an HTTP request and judges whether the HTTP request includes a predetermined keyword. A system-resource-accessing portion of the HTTP request is processed when the HTTP request includes the predetermined keyword. Then, the HTTP request is checked whether it contains a Referer field. If the header of the HTTP request includes the Referer field, the HTTP request will be treated as an external request, and the local system resource accessing will be denied even when the HTTP request includes the predetermined keyword.

Abstract: An electronic device has a cavity in which a stylus can be slidably inserted. The stylus has a retaining slot thereon. Being inserted in the cavity, the stylus firstly pushes a retainer to be moved resiliently. The stylus further presses on a stylus-releasing device that terminates the cavity, thereby engaging the stylus-releasing device in a stable configuration with a resilient force. Meanwhile the retainer inserts into the retaining slot of the stylus to hold and immobilize the stylus in the cavity. To extract the stylus, a short pressing action is exerted on the stylus, which disengages the stylus-releasing device from the stable configuration, thereby the stylus-releasing device exerts a resilient force on the stylus that is ejected partially out of the cavity to facilitate a grasp of the stylus.
