Abstract

A keyboard definition updating method for a computer system includes generating an updating scan code; storing the updating scan code into a storage device of the computer system; and accessing the updating scan code when the updating scan code stored in the storage device is detected and utilizing the updating scan code for the scan code of the computer system.

Claims

1. A keyboard definition updating method without updating BIOS for a computer system comprising:

generating an updating scan code corresponding to a new keyboard function;

storing the updating scan code into a storage device of the computer system;

detecting whether the updating scan code is stored in the storage device during a boot process of the computer system; and

if the updating scan code is in the storage device, accessing the updating scan code and utilizing the updating scan code for the computer system for realizing the new keyboard function, without updating BIOS.

2. The keyboard definition updating method of claim 1, wherein the step of generating the updating scan code comprises utilizing a text editor to generate the updating scan code.

3. The keyboard definition updating method of claim 1, wherein the step of storing the updating scan code to the storage device of the computer system comprises executing a burning program to burn the updating scan code to the storage device of the computer system.

4. The keyboard definition updating method of claim 1, wherein the step of detecting whether the updating scan code is stored in the storage device during the boot process of the computer system comprises detecting whether the updating scan code is stored in the storage device when an embedded controller of the computer system performs the boot process.

5. The keyboard definition updating method of claim 1 further comprising:

accessing an original scan code and utilizing the original scan code for the scan code of the computer system when the updating scan code is not detected in the storage device.

6. The keyboard definition updating method of claim 1, wherein the updating scan code corresponds to a keyboard of the computer system.

7. A computer system for updating keyboard definition without updating BIOS, comprising:

a processor for controlling operation of the computer system;

a keyboard for sending signals to the processor when the keyboard is pressed; and

a storage device;

wherein an updating scan code corresponding to a new keyboard function of the keyboard is generated by the computer system and stored into the storage device, the computer system detects whether the updating scan code is stored in the storage device during a boot process and after the updating scan code is detected in the storage device, the computer system accesses the updating scan code from the storage device and utilizes the updating scan code for the computer system for realizing the new keyboard function, without updating BIOS.

8. The computer system of claim 7, wherein the computer system utilizes a text editor for generating the updating scan code.

9. The computer system of claim 7, wherein the computer system utilizes the processor to execute a burning program to burn the updating scan code to the storage device.

10. The computer system of claim 7 further comprising an embedded controller for detecting whether the updating scan code is stored in the storage device while performing the boot process.

11. The computer system of claim 7, wherein when the updating scan code is not detected in the storage device, the computer system accesses an original scan code and utilizes the original scan code for the computer system.

12. The computer system of claim 7, wherein the updating scan code corresponds to the keyboard.
