Problems solved by technology

[0011] (1) Since the central processing unit of the personal computer is not completely unloaded, considerable power must be consumed;
[0012] (2) The power consumption of the central processing unit will generate high waste heat, so the central processing unit needs a set of fans and heat sinks. The fans often generate high-frequency noise, which greatly reduces the listening quality;
[0014] (4) Depending on the size and complexity of the operating system that the user enters, considerable loading time is required, which is quite inconvenient for users who only want to use the built-in CD-ROM drive of the personal computer to listen to music CDs

Embodiment Construction

[0023] Please refer to figure 1 , figure 1 is a schematic diagram of the computer system 10 of the present invention. The computer system 10 includes a power button 12 for turning on the computer system 10, an optical drive 14 for playing a CD 18 placed on a tray 16, a BIOS 20 for executing the boot program of the computer system 10, and a central The processor 22, a heat dissipation fan 24 are used to reduce the temperature of the central processing unit 22, a speaker 26 is electrically connected to the optical drive 14, and a keyboard 28 and a mouse 30 are used for inputting control signals. The BIOS 20 stores a CD playing program code 32 and a panel graphics file 34 . The interface of the optical disc drive 14 in this embodiment is a basic communication protocol which is an AT Attachment Packet Interface (ATAPI, AT Attachment Packet Interface).

Abstract

The invention provides a method for reading data stored in a CD-ROM for computers, wherein during the self testing of the basic input output system (BIOS) when the computer is booting, a CD-ROM playing program stored in the BIOS is entered, and the operation is performed under the low energy consuming condition.

Description

technical field [0001] The invention provides a method for a computer system to read data stored in a CD, so that the computer can enter a CD stored in the BIOS during the BIOS self-test stage when the computer is turned on In the playback program, and play the disc operation under the condition of low power consumption. Background technique [0002] The substantial development of personal computer technology in the past two decades has enabled personal computers to have super powerful computing capabilities and various derived functions. Almost all current computers are equipped with a central processing unit above GFLOPS level, a 3D display card that can process millions of polygons in one second and other 3D real-time calculations, and a sound card that can support stereo surround field and environmental sound effects . These functions, which were equipped with at least workstation-level computers in the past, are not news in the personal compu...
