在實務運用上，系統供電開關3同樣是介於電源(圖未示)與基本輸入輸出系統6之間的切換開關，即平台控制中樞2與基本輸入輸出系統6為同一系統內部群組，而在基本輸入輸出系統6啟動後，基本輸入輸出系統6會依據內建的邏輯程式去檢測並判斷是否為光碟機托盤彈出的請求，或者是電腦開機的指令，然而由於嵌入式控制器5僅啟動系統供電開關3，因此基本輸入輸出系統6會判斷是光碟機托盤彈出的請求，此時基本輸入輸出系統6便會依據內建的邏輯程式去驅動平台控制器中樞2先發送光碟機供電啟動訊號S2至光碟機供電開關4，以使電源供電至光碟機1而使光碟機1啟動，接著在 驅動平台控制器中樞2發送托盤彈出指令S3至光碟機1，進而使光碟機1之托盤彈出。 In practical practice, the system power supply switch 3 is also a switch between the power source (not shown) and the basic input/output system 6, that is, the platform control center 2 and the basic input/output system 6 are the same system internal group, and After the basic input/output system 6 is started, the basic input/output system 6 detects and determines whether the request is ejected from the disc tray according to the built-in logic program, or the instruction to turn on the computer, but since the embedded controller 5 only starts The system power switch 3, so the basic input and output system 6 will judge the request of the disc tray ejecting, at this time, the basic input and output system 6 will drive the platform controller hub 2 according to the built-in logic program to first send the disc machine power supply start signal. S2 to the CD player power supply switch 4, so that the power supply to the optical disk drive 1 causes the optical disk drive 1 to start, and then The drive platform controller hub 2 sends a tray eject command S3 to the optical disc drive 1, thereby ejecting the tray of the optical disc drive 1.
請繼續參閱第五圖，第五圖係顯示本發明較佳實施例所提供之光碟機托盤彈出方法之步驟流程圖。如圖所示，在電腦主機處於關機狀態下時，本實施例所提供之光碟機托盤彈出方法包含以下步驟：步驟S101是在光碟機1之彈出鍵11被按壓時，光碟機1觸發嵌入式控制器5發送一系統供電啟動訊號S1至一系統供電開關3，使系統供電開關3開啟，以啟動基本輸入輸出系統6並進一步啟動平台控制器中樞2。 Please refer to the fifth figure, which is a flow chart showing the steps of the disc tray ejecting method provided by the preferred embodiment of the present invention. As shown in the figure, when the host computer is in the off state, the disc tray ejecting method provided in this embodiment includes the following steps: Step S101 is when the eject button 11 of the disc player 1 is pressed, the disc player 1 triggers the embedding. The controller 5 sends a system power supply start signal S1 to a system power supply switch 3 to turn on the system power supply switch 3 to activate the basic input/output system 6 and further activate the platform controller hub 2.
步驟S102是基本輸入輸出系統6驅動平台控制器中樞2發送一光碟機供電啟動訊號S2至一光碟機供電開關4，使光碟機供電開關4開啟並啟動光碟機1；在實務運用上，由於光碟機1之彈出鍵11係透過裝置注意引腳12直接電性連結於嵌入式控制器5，因此當彈出鍵11被按壓時，會發送觸發訊息直接驅使嵌入式控制器5發送系統供電啟動訊號S1至系統供電開關3。 Step S102 is that the basic input/output system 6 drives the platform controller hub 2 to send a CD player power supply start signal S2 to a CD player power supply switch 4, so that the CD player power supply switch 4 is turned on and the CD player 1 is started; in practice, due to the optical disc The pop-up button 11 of the machine 1 is directly electrically connected to the embedded controller 5 through the device attention pin 12, so when the pop-up button 11 is pressed, the trigger message is sent to directly drive the embedded controller 5 to send the system power-on start signal S1. To the system power switch 3.
步驟S103是基本輸入輸出系統6初始化平台控制器中樞2之匯流排介面21，並驅動平台控制器中樞2經由匯流排介面21發送托盤彈出指令S3至光碟機1，藉以使光碟機1之托盤彈出。在實務運用上，由於基本輸入輸出系統6與平台控制器中樞2為同一內部系統群組，因此當系統供電開關3開啟時，電源會直接供電至基本輸入輸出系統6與平台控制器中樞2，以使基本輸入輸出系統6與平台控制器中樞2運作。 Step S103 is that the basic input/output system 6 initializes the bus interface interface 21 of the platform controller hub 2, and drives the platform controller hub 2 to send the tray pop-up command S3 to the optical disk drive 1 via the bus bar interface 21, so that the tray of the optical disk drive 1 is ejected. . In practice, since the basic input/output system 6 and the platform controller hub 2 are the same internal system group, when the system power supply switch 3 is turned on, the power supply is directly supplied to the basic input/output system 6 and the platform controller hub 2, In order to operate the basic input/output system 6 and the platform controller hub 2.
步驟S104是基本輸入輸出系統6驅使平台控制器中樞2發送光碟機供電啟動訊號S2至光碟機供電開關4。在實務運用上，基本輸入輸出系統6啟動後會依據內建的邏輯程式去檢測判斷狀況為何，當判斷是光碟機托盤彈出的請求而非作業系統啟動的請求時，便會驅使平台控制器中樞2發送光碟機供電啟動訊號S2至光碟機供電開關4。 Step S104 is that the basic input/output system 6 drives the platform controller hub 2 to transmit the CD player power supply start signal S2 to the CD player power supply switch 4. In practice, after the basic input/output system 6 is started, it will detect the judgment status according to the built-in logic program. When it is judged that the disc tray tray is ejected instead of the operation system startup request, the platform controller hub will be driven. 2 Send the CD player power supply start signal S2 to the CD player power supply switch 4.
步驟S105是光碟機供電開關4開啟，並啟動光碟機1。在實務運用上，由於光碟機供電開關4是用來控制電源是否供電至光碟機1，因此當光碟機供電開關4啟動後，便會使電源供電至光碟機1。 In step S105, the power supply switch 4 of the optical disk drive is turned on, and the optical disk drive 1 is started. In practice, since the CD-ROM power supply switch 4 is used to control whether the power supply is supplied to the optical disk drive 1, when the optical disk drive power switch 4 is activated, the power supply is supplied to the optical disk drive 1.
步驟S106是基本輸入輸出系統6初始化平台控制器中樞2之匯流排介面21。在實務運用上，由於光碟機1是透過匯流排電性連結於平台控制器中樞2之匯流排介面21，因此為了使平台控制器中樞2可以傳送指令至光碟機1，基本輸入輸出系統6會先初始化平台控制器中樞2之匯流排介面21。 Step S106 is that the basic input/output system 6 initializes the bus interface interface 21 of the platform controller hub 2. In practical practice, since the optical disk drive 1 is electrically connected to the busbar interface 21 of the platform controller hub 2 through the busbar, in order to enable the platform controller hub 2 to transmit commands to the optical disk drive 1, the basic input/output system 6 The bus interface interface 21 of the platform controller hub 2 is initialized first.
步驟S107是基本輸入輸出系統6驅使平台控制器中樞2經由匯流排介面21發送一托盤彈出指令S3至光碟機1，使光碟機1之托盤彈出。在實務運用上，當基本輸入輸出系統6驅使平台控制器中樞2去啟動光碟機供電開關4以及初始化平台控制器中樞2之匯流排介面21後，便會驅使平台控制器中樞2經由匯流排介面21發送托盤彈出指令S3至光碟機1，藉以此光碟機1之托盤彈出。 Step S107 is that the basic input/output system 6 drives the platform controller hub 2 to send a tray ejecting command S3 to the optical disk drive 1 via the bus bar interface 21 to eject the tray of the optical disk drive 1. In practice, when the basic input/output system 6 drives the platform controller hub 2 to start the CD player power supply switch 4 and initialize the bus controller interface 21 of the platform controller hub 2, the platform controller hub 2 is driven via the bus bar interface. 21 The tray ejecting instruction S3 is sent to the disc player 1 to eject the tray of the disc player 1.
承上所述，當基本輸入輸出系統6完成驅使平台控制器 中樞2發送托盤彈出指令S3至光碟機1之作業後，基本輸入輸出系統6更可驅使平台控制器中樞2發送光碟機供電關閉訊號至光碟機供電開關4，以及發送系統供電關閉訊號至系統供電開關3，藉以使光碟機1、平台控制器中樞2以及基本輸入輸出系統6回到原本的關閉狀態。 As described above, when the basic input/output system 6 completes driving the platform controller After the hub 2 sends the tray pop-up command S3 to the operation of the optical disk drive 1, the basic input/output system 6 can further drive the platform controller hub 2 to transmit the power supply off signal of the optical disk drive to the power supply switch 4 of the optical disk drive, and send the system power supply off signal to the system power supply. The switch 3 is used to return the optical disk drive 1, the platform controller hub 2, and the basic input/output system 6 to the original closed state.
綜上所述，相較於先前技術之光碟機托盤彈出系統必須要在電腦主機處於開機狀態下才能開啟光碟機之托盤，本發明是將光碟機之彈出鍵電性連結於嵌入式控制器，以使彈出鍵可直接觸動嵌入式控制器去啟動平台控制器中樞與基本輸入輸出系統，進而完成光碟機的啟動作業，藉此，本發明之電子裝置及光碟機托盤彈出方法可以在電腦主機處於關機狀態下使光碟機之托盤彈出，而不需要為了拿出光碟片而再次開啟電腦主機，有效的增加使用上的便利性。 In summary, the optical disc tray ejecting system of the prior art must open the tray of the optical disc drive when the computer mainframe is powered on. The present invention electrically connects the eject button of the optical disc drive to the embedded controller. So that the eject button can directly contact the embedded controller to start the platform controller hub and the basic input and output system, thereby completing the booting operation of the optical disc drive, whereby the electronic device and the disc tray ejecting method of the present invention can be located at the host computer When the machine is turned off, the tray of the optical disk drive is ejected, and the computer host is not required to be opened again in order to take out the optical disk, thereby effectively increasing the convenience of use.
藉由以上較佳具體實施例之詳述，係希望能更加清楚描述本發明之特徵與精神，而並非以上述所揭露的較佳具體實施例來對本發明之範疇加以限制。相反地，其目的是希望能涵蓋各種改變及具相等性的安排於本發明所欲申請之專利範圍的範疇內。 The features and spirit of the present invention will be more apparent from the detailed description of the preferred embodiments. On the contrary, the intention is to cover various modifications and equivalents within the scope of the invention as claimed.
