1.Whenever you turn on your Computer, the first thing you see is the BIOS software which is running.

启动计算机,你所看到的第一件事就是BIOS 软件正在执行他的操作。

2. The BIOS will try to initiate the boot sequence from the first device .

BIOS 会从第一个启动设备开始这个启动过程。

3.You are probably very familiar with two different types of software :the operating system and the applications. 

你可能对两种类型的软件很熟悉:操作系统和应用软件。

4.Inside the above-mentioned ROM three different programs are stored (actually burned).The Basic Input and Output System (BIOS)that is responsible for teaching the main processor how to deal with basic devices,such as floppy unit or hard disk and so on:the Power on Self Test (POST) which is the program in charge of the self test that is executed every time PC is powered up (like memory counting,for instance);and the Setup which is the program that allows the alteration of the parameters stered-n-he-eonfigration memog.(CMOS).

在上述只读存储器中存储着三种不同类型的程序（事实上是烧录上去的）。基本的输入输出系统（BIOS程序负责指导主处理器如何控制像软盘驱动器、硬盘之类的基本设备。加电自检程序（POST)是负责在每次计算机开机时执行

自检测的程序（比如内存容量检测）.设置程序（Setup）则是种专门用来修改CMOS中存储参数的程序。

5.The BIOS software has a numher of different roles,but its most important role is to load the perating -sytem.

BIOS 软件要执行许多不同的任务，但最重要的任务是载人操作系统

6.When you tum on your computer,the BIOS performs the following tasks.This is its usuat sequence:

1.Check the CMOS Setup for custom settings

2..Load the interrupt handlers and device drivers

3.Initialize registers and power management

4.Perform the Power on Self Test (POST)

5.Display system settings

6.Determine which devices are bootable

7.Initiate the beetstrap sequence

当你启动让算机时，BIOS就执行如下几项任务，并通常按下列顺序执行:

1检测CMOS 常规设，

2.载人中断处理程序和设备驱动程序；

3.初始化寄存器和电源管理：

4.执行加白检程序(POST)；

5.显元系统设置；

6.确定可启动设备；

7.开始自举程序。
