最新AMIBIOS详解分析解析

最新 AMI Bios 设置全程图解先以华硕的AMI Bios为例，介绍一下AMI Bios的设置：开启计算机或重新启动计算机后，在屏幕显示如下时，按下“Del”键就可以进入Bios的设置界面图片（1）要注意的是，如果按得太晚，计算机将会启动系统，这时只有重新启动计算机了。

大家可在开机后立刻按住Delete键直到进入Bios。

有些品牌机是按F1进入Bios设置的，这里请大家注意！进入后，你可以用方向键移动光标选择Bios设置界面上的选项，然后按Enter进入子菜单，用ESC键来返回主单，用PAGE UP和PAGE DOWN键或上下( ↑↓ )方向键来选择具体选项回车键确认选择，F10键保留并退出Bios设置。

接下来就正式进入Bios的设置了！首先我们会看到（如图2）一．Main(标准设定)此菜单可对基本的系统配置进行设定。

如时间，日期等图片（2）其中Primary/Secondary IDE Master/Slave 是从主IDE装置。

如果你的主板支持SATA接口就会有Third/Fourth IDE Mastert或者更多，他们分别管理例电脑里面各个IDE驱动装置的，如硬盘，光驱等等！因为各个主板的设置不同，所以在此就不详细解说这里的设置了，但是这些一般不用用户自己去设置，一般用默认的就可以，如果有特殊要求，建议用户自己对照说明书的说明进行设置，或者在论坛里单独提问！System Information这是显示系统基本硬件信息的，没有什么好讲（如图3）图片（3）基本设置了解后就进入高级设置了！二．Advanced（进阶设置）如图4：图片（4）这里就是Bios的核心设置了,新手一定要小心的设置，因为其直接关系系统的稳定和硬件的安全，千万不可以盲目乱设！1.大家先看到的是“JumperFree Configuration”（不同品牌的主板有可能不同，也可能没有）再这里可以设置CPU的一些参数，对于喜欢超频的朋友来说这里就是主攻地！(如图)大家可以看到有一个“AI Overclock Tumer”的选项，其中有一些选项，如上图，其中又以“Manual”为关键，选择后会看到如下图：对于CPU超频爱好者这些东西应该了如指掌，CPU的外频设置（CPU External Frequency）是超频的关键之一，CPU的主频（即我们平时所说的P4 3.0G等等之内的频率）是由外频和倍频相乘所得的值，比如一颗3.0G的CPU在外频为200的时候他的倍频就是15,(200MHz*15＝3000MHz)。

AMIBIOS模块结构详解完整版AMI BIOS模块结构详解完整版首先在讲AMI BIOS模块结构前,需要向大家说一样东西,就是逻辑地址.逻辑地址的形式如:XXXX:XXXX,其中前四位是段地址,后四位是偏移地址,比如ABCD:1234 物理地址=段地址*10H+偏移地址所以ABCD:1234的物理地址=ABCDH*10H+1234H=ACF04H 而ACF04H这个物理地址是相对于1M噶地址空间的如果你的BIOS大小是1M噶话那么物理地址就是ACF04H如果BIOS不是1M的话那么就要对物理地址进行换算好有条公式: BIOS文件在WINHEX中的地址 = BIOS文件相对于1M空间的地址- 常数,注:常数是根据每个BIOS的大小而确定的常数=(1024-你BIOS的大小(KB))*1024.比如你的BIOS是512KB的话那么常数就是常数=(1024-512)*1024=524288D=80000H所以ABCD:1234在512KB的BIOS中 BIOS文件在WINHEX中的地址就=ABCDH*10H+1234H-80000H=2CF04HOK 现在各位应该明白逻辑地址转化为物理地址的方法了用WINHEX打开AMI BIOS可以搜索到AMIBIOSC的字符串这里隐含很多秘密如下:(这个BIOS 512KB的)用WINHEX打开AMI BIOS可以搜索到AMIBIOSC的字符串这里隐含很多秘密.如下:(这个BIOS 512KB的)Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F00067FE0 00 00 00 00 00 00 00 00 08 0A 41 4D 49 42 494F ..........AMIBIO00067FF0 53 43 30 38 30 30 06 CE 21 40 BC 75 0C 00 83 E7 SC0800.?@紆..冪这里一共20H具体结构如下:0-2H 保留供将来使用3H 一般都是00 如果不是00的话发BIOS给我4-5H BIOS映像版本8H 都是08的9H 都是0A的 (AMIBIOSC08的长度)A-13H AMIBIOSC14-17H BIOS 核心版本18-1BH BIOS校验位1C-1DH 第一个模块的偏移地址1E-1FH 第一个模块的段地址由此可知在这个BIOS里面第一个模块的逻辑地址是 E783:000C 所以物理地址=E7830H+000CH-80000H=6783CH6783CH-8H就是第一个模块的地址了至于为什么要-8H 你自己看一下就知道了OK 第一个模块的地址找到了继续研究一下第一个模块的头部看看有什么秘密Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F 00067830 00 FF FF FF 98 07 00 00 F3 C3 B9 AA 10 00 1B E2 00067840 98 07 08 80 00 00 00 00 01 00 0C 00 20 35 01 00其中红色部分的14H就是模块头了单独提取出来Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F 00000000 98 07 00 00 F3 C3 B9 AA 10 00 1B E2 98 07 08 80 00000010 00 00 00 00 0-3H 模块大小4-7H 校验位8-9H 下一个模块的偏移地址A-BH 下一个模块的段地址C-DH 模块大小EH 模块IDFH 模块属性由此可知该模块的模块大小是0798H 校验位AAB9C3F3 下一个模块的地址为E21B:0010 模块ID为08从此可以得知下一个模块的位置如此类推......................直到最后一个模块Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F00000FD0 44 00 00 00 92 9F 03 15 FF FF FF FF 44 00 80 80 00000FE0 00 00 00 00 07 00 10 02 01 00 00 14 00 20 08 01 红色的就是模块头最后一个模块的模块头的8-BH都是FF FF FF FF的表示是最后一个模块了OK AMI BIOS模块机构详解到此完毕。

Such as time, date etc.amongPrimary/Secondary IDE Master/Slave is a device from the main IDE.If your motherboard supports SATA interface will haveThird/Fourth IDE Mastert or more, they are all inside the computer management cases of IDE driving device, such as a hard disk, CD-ROM etc.! Because each motherboard is different, so this is not a detailed explanation of the set, but the general users do not have to use the default settings, the general can, if there are special requirements, it is recommended that users control instructions that are set up in the forum, or separate questions!System InformationThis is the basic hardware information display system, not what good (Figure 3)Understand the basic settings after entering the advanced settings!Two.Advanced (advanced settings) as shown in figure 4:Here is the core of Bios is set, the novice must be carefully set, because of the direct relationship between the stability of the system and the safety of the hardware, do not blindly set!1. we first see is the "JumperFree Configuration" (different brands of the motherboard may be different, there may be no longer) here can set some parameters of CPU, for the love of friends here is the main overclocking! (Figure)You can see a "AI Overclock Tumer" option, in which there are some options, as shown above, the "Manual" as the key, you will see the following chart selection:For CPU overclocking enthusiasts these things should be well known, CPU (CPU External Frequency) the FSB set is one of the key of overclocking, CPU frequency (i.e. within we usually said P4 3.0G frequency) is multiplied by the value of frequency and frequency, such as a 3.0G CPU in the FSB is 200 time of his frequency is 15 (200MHz*15 = 3000MHz). The range can be set for general FSB 100MHz to 400MHz, but the real 300 CPU are not many, so do not blindly set high FSB, a general setting range is about 100-250 about users set to have a little bit of heightening patient, it is best to 1MHz step, plus a little bit, to to prevent excessive one-time system cannot be used normally oreven damage CPU!Memory frequency setting (DRAM Frequency) using this set of installed memory clock, set the options: 200MHz, 266MHz, 333MHz, 400MHz, Auto.AGP/PCI (AGP/PCI Frequency), the frequency setting operation frequency of this project can modify the AGP/PCI equipment, in order to obtain better system performance and overclocking performance, setting value: [Auto], [66.66/33.33],[72.73/36.36]. But please set the appropriate user, if improper setting may cause AGP/PCI equipment can not be used normally!Needless to say the voltage setting,Is the working voltage setting device, recommended for most users do not easily modify, so as to prevent damage to the unit because the voltage is not correct! Is the user to modify must not blindly, to step the way a little bit of pressure, the maximum value should not exceed 0.3V.2. CPU Configuration (CPU) of this project can let you know the related index of CPU and change CPU.Here you can get all kinds of information CPU, because this is the latest ASUS Bios program, so it increased the number of new CPU information, such as the three level cache, and adds to the enhanced options Intel64 CPU! But these projects for the general CPU is not what meaning! Some of the options here basically don't change, but here is the most meaningful option is the last Hyper Threading Technology option, which isswitched on P4 CPU hyper threading, hyper threading CPU with P4 user should know that some programs can not well support hyper threading technology, and sometimes even lead to crashes, such as the Internet WinXP SP1 IE P4 hyperthreaded users have frequent crashes the CPU occupancy rate of 100%, this is because it cannot fully support hyper threading technology (but as long as the update to the SP2 update or upgrade the system without this problem.) then we can close the hyper threading technology CPU, as long as the value of the can be set to Disabled! But this will not be able to fully play the performance of P4 hyper threading CPU!3. Chipset (Advanced chipset features) using this menu you can modify the chipset registers, the performance optimization system.Configure SDRAM Timing bySetting determines whether the SDRAM clock is set by reading the memory module of SPD (SerialPresence Detect) EEPROM content. According to the SPD set to Enabled will automatically set the project, if you have the option not to Disabled, will appear the following items: SDRAM CAS# Latency, DRAM RAS Precharge, DRAM RAS to CAS Delay DRAM, precharge Delay and DRAM Burst Length. If you are not familiar with these settings do not modify the chip group.SDRAM CAS# Latency (SDRAM CAS# delay)Control and accept the start delay time after read command in SDRAM (in clock cycles). Set value: 2, 2.5, 3 (clocks). Thesmaller the value of the more powerful performance! But the relative decline of stability!DRAM RAS Precharge (Precharge command delay)The project control when SDREM sends a Precharge command, how much time will no longer send command. Set value: 4, 3, 2 (clocks)RAS to CAS Delay (delay RAS to CAS)When DRAM refresh after all ranks to separate addressing. This setting allows you to decide from RAS (row address filtering) conversion to CAS (column address filtering) delay time. A smaller clock cycle will make DRAM performance faster. Set value: 4, 3, 2 (clocks)DRAM precharge Delay (pulse cycle)This setting is used to control for SDRAM clock cycle using SDRAM parameters! Set value: 8, 7, 6, 5 (clocks)SDRAM Burst Length (SDRAM access burst length)This setting allows you to set the length of the size of the outbreak of DRAM access. The outbreak is characterized in that the DRAM forecast their location of each memory access technology in the first address. Using this feature, you must define the burst length, is the beginning of the actual length of the pulse burst. At the same time allows the internal address counter can correctly generate the next address location. Thelarger the size of memory more quickly. Setting: 4, 8 (clocks).AGP Aperture Size (AGP memory allocation)This system is used to control the number of memory can be allocated to the AGP display card. The aperture is used for graphics memory address space of a part of the PCI memory address range. Enter the aperture within the scope of the master clock cycle will be translated directly to AGP. Setting: 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and MB 256.4.OnBoard Devices Configuration (integrated equipment set)Here are some options to manage a variety of integrated motherboard hardware facilities, users basically do not change the settings! This is no longer so paralepsis! Such as the need to change, please check the motherboard manual!5.PCI Pnp (plug and play device settings)Here is the setting plug project advanced settings and PCI, users do not need to change any item, you can keep the default. In this set, incorrect values will lead to damage to the system!B Configuration (USB device)USB port device settings, everyone can understand, no need to say more! Only the transmission mode which has a FullSpeed and HiSpeed, if we USB2.0 it is set to HiSpeed, FullSpeed is a simulation of high speed transmission, no HiSpeed fast!Three.Power (power management settings) figure:In front of four without what good talk, because the motherboard brand is different, so there may be some users do not have the above options, including APM Configuration (advanced power setting) and Hardware Monitor (monitoring system) two options.1. APM Configuration (advanced power setting)2.Hardware Monitor (monitoring system)Four.Boot (boot device)This menu is to change the system boot device and related settings, are more important in Bios.1. Boot Device Priority (boot device)This project is set to start when the system starts the memory order, such as we have to start from the CD-ROM during installation of the operating system, we must take the 1st Device Priority is set to become your CD-ROM, figure is arranged on the hard disk, so when the system boots the first startup is hard, if not to suggest that you start from the CD-ROM. The first startup settings become hard disk, other startup items set to Disable, this system will start relatively quickly, because the system not to search for other redundant hardware device!TwoBoot Settings Configuration (startup options)Here are some of the startup project settings system! It is convenient for users to better habits and improve the system performance.1. QuickBoot (quick start set)This project can set whether the computer self-test function at startup, and to accelerate the speed of system, if set to "Disable" system will be in the implementation of all self boot time, but it will start slowing down! The general setting is Enabled"2. Full Screen Logo (fulllogo display settings)Here is the set whether to open the boot Logo settings, if you don't want to boot Logo can be set to Disable"3. Add On ROM Display Mode (accessory software display)This project is the accessory device software allows you to set the display mode, the general is set to "Force BIOS" on it.4. Bootup NunLock (keypad lock switch)Is to set the boot is automatically opened on the keypad NumLock. General settings for On5. PS/2 Mouse SupportSet whether the PS/2 mouse support function of this project. Can be set to AUTO.6. Typematic Rate (keyboard settings reflect the frequency)This is to let you choose the keyboard to reflect the speed of frequency options, usually set to "fast"7. Boot To OS/2 (OS/2 system)This project allows you to choose whether to activate the OS/2 operating system compatibility mode, generally set to No"8. Wait For "F1" If Error (ErrorMessage)This project is set if an error occurs when the system starts to display press the "F1" button to confirm to continue the boot, usually set to "Enabled"9. Hit "DEL" Messgae Display (press DEL prompt)This option is displayed by pressing the Del key to enter Bios setup tips at boot time, if you choose "Disable" will not see this article at the beginning of the sentence "Press DEL to Run Steup, Presss TAB to display BIOS Post Message" message, usually set to "Enabled"10. Interrupt 19 Capture (PCI built in program startup settings)When the card comes with software you use PCI when you set thisto "Enabled"3. Security (safety performance options)1.Change Supervisor Password (administrator password)The administrator password set, when setting the password after several options, including a "User Password" option, which is the user password settings, like the Windows user password, they can be set into a variety of different access rights (Use Access Level), whichNo Access users to store Bios settingsView Only users can only view Bios settings cannot change settingsLimited allows the user to change the settingsFull Access users can change Bios settingsThere are several common optionsClear User Password clear password更改密码密码检查2。
