Abstract

A control apparatus for driving different types of CD-ROMs includes a control panel provided at the front panel of the computer frame. The control panel has a plurality of keys and a display window for outputting key signals representative of driving a specific CD-ROM title and the operation of the CD-ROM drive, and for displaying a message representing the kind of CD-ROM and icons representing the functions of the respective keys. A micro-controller cooperates with the control panel and the central processing unit (CPU) of the computer system for displaying the icons and the kind of CD-ROM on the display window, and in response to a key signal produces preset command signals for driving the CD-ROM title and the operation of the CD-ROM drive. The control panel of the invention simplifies the driving operations of various CD-ROMs, which results in easy access to the multimedia computer for beginners.

8. A method of controlling a CD-ROM drive of a computer system to drive different types of CD-ROMs, said method comprising the steps of:

providing a display panel and a plurality of input keys disposed adjacent to said display panel in a control panel;

displaying icons designating CD-ROM titles on said display panel, each icon being disposed adjacent to different corresponding ones of said input keys;

inserting a CD-ROM into the CD-ROM drive;

displaying a message indicating CD-ROM by type inserted in the CD-ROM drive, said message disposed adjacent to said corresponding one of said input keys;

determining whether said input key designated for driving the specific type of CD-ROM is selected by a user; and

respectively displaying sub-icons on the display panel, said sub-icons disposed adjacent to said corresponding ones of input keys, said icons indicating available control functions designated by each respective input key when one of CD-ROM driving input keys is selected by the user.

9. The method of claim 8, further comprising the steps of:

determining whether an input key designated for tray open/close operation of the CD-ROM drive is selected before displaying a message indicating the type of CD-ROM; and

outputting a command signal for opening/closing the tray of the CD-ROM drive when the tray open/close key is selected by the user.

10. A control apparatus for controlling a CD-ROM drive of a computer system to drive different types of CD-ROMs in the computer system, comprising:
