Abstract

A system for updating a sign-on logo image file in a computer includes: a storage medium (7) for storing image files; application software (1) for loading a selected image file, converting the selected image file into a designated format image file, and compressing the designated format image file into a corresponding sign-on logo image file; a dynamic link library (DLL) (2) for receiving the sign-on logo image file from the application software; a basic input/output system (BIOS) (4) for receiving the sign-on logo image file from the DLL through a driver model (3) which connects the DLL with the BIOS, determining whether the sign-on logo image file is valid according a size of the sign-on logo image file, and updating the sign-on logo image file in the computer if the sign-on logo image file is valid; and a read only memory (5) for storing the sign-on logo image file. A related method is also disclosed.

Claims

1. A system for updating a sign-on logo image file in a computer, comprising:

a storage medium for storing various kinds of image files;

application software for loading a selected image file, converting the selected image file into a designated format image file, and compressing the designated format image file into a corresponding sign-on logo image file;

a dynamic link library (DLL) for receiving the sign-on logo image file from the application software;

a basic input/output system (BIOS) for receiving the sign-on logo image file from the DLL through a driver model which connects the DLL with the BIOS, determining whether the sign-on logo image file are valid according a size of the sign-on logo image file, and updating the sign-on logo image file in the computer if the sign-on logo image file is valid; and

a read only memory for storing the sign-on logo image file.

2. The system according to claim 1, wherein the application software comprises:

an image loading module for loading the selected image file from the storage medium;

an image converting module for converting the selected image file into the designated format image file;

an image compressing module for compressing the designated format image file into the sign-on logo image file; and

a communicating module for transmitting the sign-on logo image file to the DLL.

3. The system according to claim 2, wherein the application software further comprises:

an image saving module for saving the designated format image file in the storage medium.

4. The system according to claim 2, wherein the application software further comprises:

an image previewing module for previewing a display of the selected image file before updating the sign-on logo image file.

5. The system according to claim 2, wherein the system is connected with a remote server through a network, the remote server controlling the application software through the network.

6. A computer-based method for updating a sign-on logo image file in a computer and displaying the updated image file, comprising the steps of:

loading a selected image file from a storage medium;

converting the selected image file into a designated format image file;

compressing the designated format image file into a sign-on logo image file;

transmitting the sign-on logo image file to a dynamic link library (DLL);

transmitting the sign-on logo image file to a basic input/output system (BIOS) through a driver model;

determining whether the sign-on logo image file is valid according to a size of the sign-on logo image file;

updating the sign-on logo image file stored in a read only memory (ROM) with the selected image file, if the sign-on logo image file is valid;

returning to the step of loading a selected image file, if the sign-on logo image file is not valid; and

restarting the computer to display the selected image file.

7. The method according to claim 6, further comprising the step of:

saving the designated format image file in the storage medium.

8. The method according to claim 6, further comprising the steps of:

previewing the selected image file to determine whether the display of the selected image file is correct;

returning to the step of loading a selected image file, if the display of the selected image file is not correct; and

updating the sign-on logo image file stored in the ROM with the selected image file, if the display of the selected image file is correct.

9. A method for updating and displaying a sign-on logo image file of a computer, comprising the steps of:

initializing a graphic interface under an operating system (OS) environment;

loading a selected image file from a storage medium of said computer via said graphic interface;

updating said sign-on logo image file stored in a read only memory (ROM) of said computer with said selected image file; and

restarting said computer to display said updated sign-on logo image file.

10. The method according to claim 9, further comprising the step of previewing said updated sign-on logo image file via said graphic interface before said restarting step.

11. The method according to claim 9, further comprising the step of transmitting said image file to said ROM via a basic input/output system (BIOS) which acquires said image file through a dynamic link library (DLL) and a driver model before said updating step.

12. The method according to claim 11, further comprising the step of verifying validity of said image file by said BIOS.

13. The method according to claim 9, wherein said OS is one of the group consisting of Windows 98, Windows 2000, Windows XP, and other graphic-interface OSs.

14. The method according to claim 9, further comprising the step of connecting to a remote server through a network and allowing users of said remote server to remotely control fulfillment of said method via said graphic interface.
