## Background
FIELD OF THE INVENTION
The present invention relates to computer motherboards, and more particularly, to a computer motherboard with a Basic Input Output System (BIOS) capable of built-in configuration display.
BACKGROUND OF THE INVENTION
Despite its interfaces, a conventional Basic Input Output System (BIOS) does not give a complete picture of a central processing unit (CPU) and memory but only displays some usual functional information thereof. CPUs and memory are increasingly powerful and therefore involve creating an increasingly large amount of information. To gain insight into information related to the CPU and memory installed in a computer system, a user has to execute a special software under an operating system and look for the information of the CPU and memory. The user cannot, however, peruse the information related to the CPU, memory, and their functions after gaining access to the BIOS settings during a boot procedure performed on the computer system.
Conventional CPU-Z application software enables users to gain insight into information related to the CPU and memory installed in the computer system. However, to execute conventional CPU-Z application software, a computer motherboard has to enter the operating system. Information about conventional CPU-Z application software is available on the Website http://www.cpuid.com/cpuz.php.
The inventor of the present invention realized the aforesaid drawbacks of the conventional computer motherboard and endeavored to overcome the aforesaid drawbacks by inventing a computer motherboard with a BIOS capable of built-in configuration display whereby a user selects, upon entry into a BIOS setup utility, an option of executing operation of built-in configuration display so as for configuration of the CPU and memory to be displayed without using an operating system.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, which is a schematic view of the framework of a computer motherboard of the present invention, a computer motherboard 10 of the present invention is characterized in that: a Basic Input Output System (BIOS) 20 is capable of built-in configuration display so as to allow a user to enter the BIOS screen after the computer is powered on (for example, by pressing the Del key on a keyboard) and gain insight into information related to a central processing unit (CPU), memory and functions thereof by following operation instructions displayed on the BIOS screen.
The computer motherboard 10 of the present invention comprises the BIOS 20, a central processing unit (CPU) 101, and at least a memory module 30. Unlike a conventional BIOS, the BIOS 20 comprises a first means 201 and a second means 203. The computer motherboard 10 of the present invention is described hereunder.
The first means 201 is code integral to the BIOS 20. The first means 201 is executable by the CPU 101 of the computer motherboard 10. In an execution environment of the BIOS 20, the CPU 101 executes the first means 201 and thereby enables acquisition of CPU configuration data stored on the CPU 101 and configuration data for displaying the CPU 101. The CPU configuration data displayed by means of the first means 201 comprises a type of cache memory, quantity of cache memory, and a type of support for multimedia extensions.
The second means 203 is code integral to the BIOS 20. The second means 203 is executable by the CPU 101 of the computer motherboard 10. In an execution environment of the BIOS 20, the CPU 101 executes the second means 203 and thereby enables acquisition of memory module configuration data stored on the memory modules 30 and configuration data for displaying the memory modules 30. The memory module configuration data displayed by means of the second means 203 each comprises Serial Presence Detect (SPD) data stored on the at least a memory module 30.
Referring to FIG. 2, which is a flow chart of configuration display executed by the computer motherboard 10 of the present invention, after the computer motherboard 10 is powered on (S201), the BIOS 20 checks the keyboard to determine whether the Del key has been pressed (S202), and a TRUE determination is followed by entry into a BIOS setup utility (S203), or else booting continues (S204). Referring to FIG. 3, which is a screen shot of commencement of operation of configuration display upon the user's entry into a BIOS setup utility in step S203 of the present invention, the CPU 101 executes the first means 201 and the second means 203 to detect and read the CPU configuration data stored on the CPU 101 and the Serial Presence Detect (SPD) data stored on the at least a memory module 30 (S205).
Afterward, the user selects options available in the BIOS 20 to execute CPU or memory configuration display, or, alternatively, the user presses a preset hot key on the keyboard to execute CPU or memory configuration display (S206).
Referring to FIG. 3 again, in step S205, the user selects CPU configuration display options available in the BIOS 20 to execute CPU configuration display. Referring to FIGS. 4 and 5, the CPU 101 executes the first means 201 to display the CPU configuration data. Referring to FIG. 6, alternatively, the user presses a preset hot key, such as key F4, on the keyboard to execute CPU configuration display.
Referring to FIG. 3 again, in step S205, the user selects memory configuration display options available in the BIOS 20 to execute memory configuration display. Referring to FIG. 7, the CPU 101 executes the second means 203 to display the SPD data of the memory module 30. Referring to FIG. 8, the user presses a preset hot key, such as key F5, on the keyboard to determine whether the memory modules 30 have been inserted into memory slots.
Step S207 involves determining whether to exit the BIOS setup utility, wherein a TRUE determination is followed by rebooting the computer motherboard 10 (S208), and a FALSE determination is followed by going back to step S206.
The type of support for multimedia extensions depends on the CPU 101 and is, for example, one selected from the group consisting of multimedia extensions (MMX), Streaming SIMD Extensions (SSE), Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3), Streaming SIMD Extensions 4 (SSE4), and Streaming SIMD Extensions 5 (SSE5).
The CPU configuration data depend on the CPU 101 and further comprise support for a page attribute table (PAT), support for a page size extension (PSE), and a version of a memory controller.
The at least a memory module 30 is, for example, a single in-line memory module (SIMM) or a double in-line memory module (DIMM).
The computer motherboard of the present invention enables detailed information related to a CPU and memory to be displayed in a BIOS and enables users to gain insight into performance of the CPU and memory without using an operating system—the advantages of the present invention.
The above description serves to expound preferred embodiments of the present invention rather than limit the scope of application of the present invention.
