Description

Motherboard with a display device capable of displaying power-on status

The invention relates to a mainboard, in particular to a mainboard with a display device capable of displaying the power-on state.

Generally, the specifications of motherboards used in industrial computers are quite different from the specifications of motherboards used in personal computers. Therefore, when producing motherboards, the methods of testing and debugging the motherboards used in industrial computers will also be different from those used in personal computers. The use of the motherboard is not the same. When testing and debugging a mainboard used by an industrial computer, the mainboard must be inserted into the backboard of an industrial computer, and a test card must be connected externally to test the mainboard. When the test result of this main board is that there is a bug (bug) and cannot be started normally, it will cause a crash phenomenon and be difficult to debug. Testers usually cannot know exactly which part of the motherboard is wrong, and must spend a lot of time and effort to find out the wrong part for debugging. Therefore, the testing and debugging work of the mainboard for the existing industrial computer is very troublesome and inefficient.

The purpose of the present invention is to provide a motherboard with a display device capable of displaying the power-on state, so that testers can directly know the state of the processor from the information displayed on the display device for testing and debugging.

The object of the present invention is achieved by providing a motherboard, which includes: a bus, used to transmit data signals and address signals; a memory, electrically connected to the bus, used to store a boot program; a socket , electrically connected to the bus; a display device, installed on the socket in a pluggable manner, which includes: a display, used to display the data signal of the bus; and a position identifier, used to identify the bus address signal of the bus, wherein when the address signal of the bus is a specific position, the position recognizer will activate the display so that it can display the data signal of the bus; accessing the boot program in the memory; wherein when the boot program is executed by the processor, the boot program can output its information data to the specific location via the bus, and the position identifier of the display device will recognize the specific location and activate the display to display the informational data.

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein:

Fig. 1 is the functional block diagram of motherboard of the present invention;

Fig. 2 is a schematic diagram of a display device pluggable on the motherboard of Fig. 1;

FIG. 3 is a functional block diagram of the display device in FIG. 2 .

Please refer to Figure 1. FIG. 1 is a functional block diagram of a motherboard 10 of the present invention. The motherboard 10 includes a bus 12 for transmitting data signals and address signals, a memory 14 electrically connected to the bus 12 for storing a boot program 16, a socket 18 electrically connected to the bus 12, and a processor 20 . The processor 20 can access the boot program 16 in the memory 14 through the bus 12 when booting. Bus 12 is an ISA bus. The boot program 16 is a basic input/output program (Basic input/output system-BIOS). The memory 14 is a flash memory (flash memory).

Please refer to Figure 2 and Figure 3. FIG. 2 is a schematic diagram of a pluggable display device 22 on the motherboard 10 of FIG. 1 . FIG. 3 is a functional block diagram of the display device 22 of FIG. 2 . The motherboard 10 further includes a display device 22 installed on the socket 18 in a pluggable manner. The display device 22 includes a display 24 for displaying the data signal of the bus 12, a position identifier 26 for identifying the address signal of the bus 12, a memory 28 for storing an identification code, and two digital display elements 30 , used to display the data signal of the bus 12 with several numbers. Both the memory 28 and the display 24 of the display device 22 are controlled by a read/write signal.

When the processor 20 is executing the boot program 16 , the boot program 16 will first detect whether the display device 22 has been installed in the socket 18 . When the position recognizer 26 recognizes that the address signal of the bus 12 is a specific position, and a read/write signal of the bus 12 is an input (read) state, the identification code in the memory 28 can be read into the bus 12, so that the boot program 16 It can be known that the display device 22 has been installed in the socket 18 by reading the identification code and confirming.

When the boot program 16 outputs the information data to the specific location via the bus 12 , the location recognizer 26 will recognize the specific location, and activate the display 24 to display the information data. When the position recognizer 26 recognizes that the address signal of the bus 12 is the specific position, and a read/write signal of the bus 12 is output (write), the display 24 will display the data signal of the bus 12 in numbers.

Since the display device 22 and the memory 14 storing the BIOS are located on the same bus 12 . When the motherboard 10 is turned on, the processor 20 reads the BIOS via the bus 12 to the memory 14 and executes it. That is to say, as long as the bus 12 can normally transmit data and address signals, when the processor 20 reads and executes the BIOS via the bus 12, the display device 22 can digitally display the data signals transmitted on the bus 12. Therefore, testers can directly know the state of the processor 20 from the information displayed on the display device 22 for testing and debugging, so that the testing and debugging of the motherboard 10 are more efficient.

The motherboard 10 of the present invention includes a display device 22 , and the display device 22 and the memory 14 storing the boot program 16 are electrically connected to the same bus 12 . When the boot program 16 is executed by the processor 20, the boot program 16 can output its information data to a specific position via the bus 12, and the display device 22 will recognize the specific position, and use the data signal transmitted on the bus 12 The numbers are displayed, so testers can directly know the execution status of the processor 20 through the information displayed on the display device 22 . The testers can not only immediately know the test results of each stage, but also know exactly which part is wrong, so that the testing and debugging work of the motherboard 10 is more efficient.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention should fall within the scope of the patent of the present invention.
