由于 PC 可以发出大量哔声代码，因此超级用户中有很多关于哔声代码的问题！我希望这篇文章能够通过我虚构的问题，帮助社区解答所有（我敢说所有吗？）哔声代码的问题。
当我尝试打开 PC 时，我听到一些哔哔声。这不是硬盘或风扇发出的哔哔声，而是主板发出的哔哔声。无论哔哔声次数多少，这些哔哔声代表什么？
答案1
蜂鸣声通常称为蜂鸣代码。它们通常用于指示某些硬件的状态。
蜂鸣代码是计算机发出的音频信号，用于宣布计算机首次开机时执行的简短诊断测试序列（称为开机自检或 POST）的结果。 POST 是计算机基本输入/输出操作系统 ( BIOS ) 中包含的一个小程序，用于检查以确保必要的硬件存在并且所需的内存可以访问。 如果所有测试都正确无误，计算机通常会发出一声蜂鸣并继续启动过程。 如果出现问题，计算机将在显示器屏幕上显示一条错误消息，并通过一系列音调、数量和持续时间不同的蜂鸣声以声音形式宣布错误（当显示器或图形组件出现错误时，这尤其有用）。 蜂鸣序列实际上是一种编码信息（蜂鸣代码），旨在告诉用户计算机出了什么问题。
蜂鸣代码没有官方标准；音频模式因计算机 BIOS 程序制造商而异。如果在启动时发出错误消息，用户必须首先确定计算机运行的是哪种 BIOS（Phoenix 或 AMI 最受欢迎），然后使用该信息查找正在发送的特定蜂鸣代码序列。BIOS 信息和蜂鸣代码解释可以在计算机随附的手册和制造商的网站上找到。
因此，要理解它，您需要做的第一件事就是找出您拥有的 BIOS（这可以通过阅读手册来实现。如果您没有手册，制造商通常会在其网站上保留一份电子版。另请参阅我如何才能知道我的电脑是什么主板？
现在，蜂鸣代码：
