代码含义说明C0关闭Chipset 的Cache关闭OEM厂商设计的Cache控制器CPU状态(1 FLAGS)检验
1
微处理器测试1测试CPU下列状态：carry,zero,sign,overflow. BIOS设定各项状态并进行检验。把各项状态设为OFF并确认设定成功。
2微处理器测试2读/写/检验所有CPU的缓存器, SS, SP及BP缓存器含有FF及00的数据式不做此检验.
3初始化芯片组关闭NMI,PIE,AIE,UEI,SQWV.关闭video,parity checking,DMA.重置点运算器(math coprpcessor).清除有分页缓存器,  CMOS关闭位组.初始化定时器0, 1, 2, 包括设定EISA定时器成可认别状态.初始化DMA控制器0秘1，初始化中断控制器0与1，初始化EISA延伸缓存器
4记忆体测试测试RAM可以正常进行Refreshed，确保记忆体的Refresh功能可以运作. 5初化键盘及清除屏幕画面键盘控制器初始化，并清除屏幕画面.( IOR*. IOW*.  RESET .Clock SA2 ) 6保留保留
7测试CMOS接口以及电池状态确认CMOS可正常运作，并侦测电池状态是否良好.
