52、BM兼容PC机后，BIOS首先执行一系列任务，即自检。任务完成硬件的检测和初始化。每次自检开始，BIOS都输出检测点到80h端口。程序员或技术人员利用这个代码来解决相应的系统错 误或者判断正在执行何种程序。有些主板通过配置的LED灯来显示80h位的电流状态，如若没有，可通 过购买80h端口卡来实现此功能。如果BIOS发现终端错误，便会再显示设备的左上角显示相应的错误 信息。不过在CGA上有时会显示一堆杂乱信息。在BIOS自检之前死机，屏幕不显示任何提示信息。终端自检错误自检过程通过几个相应的程序完成，如果某个程序出错，自检程序会建立一个终端错误并关闭系统。关 闭系统之前，错误处理机制通过鸣音来

53、表示检测点错误，并把错误信息输出到80h端口，同时尝试初始 化VIDEO设备，在屏幕的左上角显示出现的错误。鸣音码表示错误的规划如下：8位错误代码被拆分成4位一组的两组。每组约定4进制（逢四进一）每组数字通过短音表示。例如：检测点16h=00 01 01 10 =1-2-3自检规则如下列出输出到80h的检测点代码，鸣音码显示终端错误，代码对Phoenexbios 4.0 Release 6.0有效。注：如下排在BIOS代码中显示的检测点数字，在自检过程中顺序差异可能很大.鸣音码自检码说明/检测点1-1-1-302Verify Real Mode开启实模式1-1-2-104Get CPU typ
