由於 PC 可以發出的蜂鳴代碼數量較多，超級使用者上有很多關於蜂鳴代碼的問題！我希望這篇文章將有助於為所有（我敢說全部嗎？）蜂鳴代碼以及我的虛構問題提供社區答案。
當我嘗試打開電腦時，我聽到一些蜂鳴聲。這不是硬碟或風扇發出的蜂鳴聲，而是主機板發出的蜂鳴聲。不管蜂鳴聲有多少次，蜂鳴聲代表什麼？
答案1
蜂鳴聲通常稱為蜂鳴代碼。它們提供指示，通常是關於某些硬體的狀態。
蜂鳴代碼是電腦發出的音訊訊號，用於宣布電腦首次加電時執行的簡短診斷測試序列的結果（稱為開機自我檢測或 POST）。 POST 是電腦基本輸入/輸出作業系統 (BIOS) 中包含的一個小程序，用於檢查以確保必要的硬體存在並且所需的記憶體可存取。如果一切測試正確，計算機通常會發出蜂鳴聲並繼續啟動過程。如果出現問題，電腦將在顯示器螢幕上顯示錯誤訊息，並透過一系列音調、數量和持續時間各不相同的蜂鳴聲以聲音方式宣布錯誤（當顯示器或圖形組件存在錯誤時，這特別有用） 。蜂鳴序列實際上是一條編碼訊息（蜂鳴代碼），旨在告訴使用者電腦出了什麼問題。
蜂鳴代碼沒有官方標準；音訊模式因電腦 BIOS 程式的製造商而異。如果啟動時發出錯誤訊息，使用者必須先確定電腦正在執行哪種 BIOS（Phoenix 或 AMI 是最受歡迎的），並使用該資訊來尋找正在傳送的特定蜂鳴代碼序列。 BIOS 資訊和蜂鳴代碼解釋可以在電腦附帶的手冊和製造商的網站上找到。
因此，要了解它，您需要做的第一件事就是找出您擁有的BIOS（這可以透過閱讀手冊來實現。如果您沒有，製造商通常會在他們的網站上保留電子副本。另外看如何知道我的電腦使用的是什麼主機板？
