摘要： A computer system is capable of playing audio CDs in a CD-ROM drive independent of the operating system by using an embedded CD-ROM drive application or a CD-ROM drive controller. When an audio CD mode switch of the computer system is in an “on” state and the main power switch of the computer is in an “off state” the computer system is in an audio CD mode. When the computer is placed in such an audio CD mode, the computer either loads the embedded CD application from a non-volatile memory region such as read-only-memory (ROM) region or enables the CD-ROM drive controller of the CD-ROM drive to receive a CD selection and transmit the selections to the CD-ROM drive. The embedded CD application includes an embedded CD-ROM device driver for driving the CD-ROM drive to process audio CDs, power-on-self test (POST) code for selectively powering and initializing hardware device in the computer system, initialization code for the embedded CD-ROM device driver, and system management interrupt/keyboard controller interface code used for processing the selection of a CD button of the computer system.
