1. Field of the Invention
The present disclosure relates to a basic input output system (BIOS) refresh apparatus.
2. Description of Related Art
At present, a traditional way to solve problems of a motherboard caused by BIOS failure is replacing the BIOS, which requires specialized tools and professional skill. While another way is having two separate BIOSes on the motherboard, which requires additional real estate on the motherboard, thus, reducing the efficiency and the number of components on the motherboard.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the drawings, is illustrated by way of example and not by limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
In use, when the BIOS refresh apparatus 100 is used to refresh the BIOS chip 11 of the motherboard 2, a good BIOS chip 21 is mounted to the slave BIOS socket 20, and the master BIOS socket 10 covers on and electrically connects to the BIOS chip 11 of the motherboard 2. The first pin 1 and the fourth pin 4 of the jumper device 30 are connected together through a first jumper (not shown), and the second pin 2 and the third pin 3 of the jumper device 30 are connected together through a second jumper (not shown). The motherboard 2 is powered on, the BIOS chip 21 mounted on the slave BIOS socket 20 receives a high level signal from the signal pin INITJ of the slave BIOS socket 20 to guide the motherboard into a disk operating system (DOS) mode or a Windows mode. After that, the first pin 1 and the second pin 2 of the jumper device 30 are connected together through the first jumper, and the third pin 3 and the fourth pin 4 of the jumper device 30 are connected together through the second jumper. Thus, the signal pin INITJ of the master BIOS socket 20 receives a low level signal, and at the same time, the motherboard is in the DOS mode or the Windows mode, therefore, a BIOS program stored in the motherboard can automatically refresh the BIOS chip 11 of the motherboard 2. The BIOS refresh apparatus 100 can be removed after the BIOS chip 11 is refreshed. The motherboard 2 is powered on again, the BIOS chip 11 of the motherboard 2 guides the motherboard 2 into the DOS mode or the Windows mode, namely, the BIOS chip 11 of the motherboard 2 is restored.
When the BIOS refresh apparatus 100 is used to copy the BIOS file from the BIOS chip 11 of the motherboard 2 to a blank BIOS chip 21, the blank BIOS chip 21 is mounted to the slave BIOS socket 20, and the master BIOS socket 10 covers on and electrically connects to the BIOS chip 11 of the motherboard 2. The first pin 1 and the second pin 2 of the jumper device 30 are connected together through a first jumper (not shown), and the third pin 3 and the fourth pin 4 of the jumper device 30 are connected together through a second jumper (not shown). The motherboard 2 is powered on, and the BIOS chip 11 of the motherboard 2 receives a high level signal through the signal pin INITJ of the master BIOS socket 10, to guide the motherboard 2 into a DOS mode or a Windows mode. After that, the first pin 1 and the fourth pin 4 of the jumper device 30 are connected together through the first jumper, and the second pin 2 and the third pin 3 of the jumper device 30 are connected together through the second jumper. The signal pin INITJ of the slave BIOS socket 20 receives a high level signal, and at the same time, the motherboard 2 is in the DOS mode or the Windows mode, therefore, a BIOS program stored in the motherboard 2 can automatically copy the BIOS file from the BIOS chip 11 of the motherboard 2 to the blank BIOS chip 21. The BIOS refresh apparatus 100 can be removed after the BIOS file of the BIOS chip 11 is copied, and then the blank BIOS chip 21 mounted on the slave BIOS socket 20 can be removed.
The BIOS refresh apparatus 100 can automatically refresh the BIOS chip 11 of the motherboard 2 and copy the BIOS file of the BIOS chip 11 of the motherboard 2 to a blank BIOS chip 21. Therefore, the BIOS refresh apparatus 100 is simple and cost effective.
It is to be understood, however, that even though numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
