I have already learned some basic BIOS basics, and settings, so in this article I will give a more detailed introduction of the BIOS overclocking settings, I hope for those who want to overclocking but did not pick up the overclocking player can have some help.
As with the AMI bios, press the "Del" key to enter the BIOS setup menu (some press the F1 key) when the screen is powered on:
After entering, you will see the following menu, there may be some differences, but basically the same, and the name is different, but basically the same effect
We can use the arrow keys to move the cursor, enter confirm, Esc key back, with Pageup,pagedown and the number of keys to adjust settings, in any settings menu can press the F10 key to exit and save settings, these and AMI BIOS settings almost! Then it is the entry setting!
A Softmenu Setup (soft overclocking settings)
In fact, this soft Menu Setup, is a technical board unique technology, here provides a rich CPU FSB, frequency modulation (requires CPU support), AGP/PCI bus frequency and cpu/memory/AGP voltage regulation frequency and so on. This project is equivalent to "Frequency/voltage control" in some motherboards
There are some basic information about the CPU, the following options are the main CPU overclocking options!
1. CPU operating Speed (CPU FSB settings):
This project shows how fast the processor is operating based on the type of processor you use and the speed at which you can select the user Define option to manually enter its operating speed. As shown in figure:
All right, I'm going to put down the BIOS settings first, and I'll explain to you how overclocking and overclocking are the principles that will allow you to better enter the next step of the BIOS setup overclocking!
CPU overclocking, its main purpose is to improve the CPU's working frequency, that is, CPU frequency. The CPU's frequency is also the product of FSB (FSB) and frequency multiplier (multiplier Factor). For example, a CPU FSB 200MHz, frequency multiplier of 10, you can calculate its frequency = FSB x frequency multiplier =200mhzx10 = 2000MHz, that is 2.0GHz.
The frequency of the CPU can be increased by changing the CPU frequency multiplier or FSB to achieve. But if you're using an Intel CPU, you can ignore the multiplier because Intelcpu uses a special manufacturing process to prevent it from changing the multiplier. But there is a part of Intel's engineering samples that do not have a lock on the frequency multiplier, AMD's CPU can modify the multiplier. Although the upgrade CPU FSB or multiplier can make the CPU to achieve the same frequency, such as a 2.0GHz CPU, it with 200*10=2.0, we can increase the frequency to 20, and the FSB to 100MHz, or the FSB can be raised to 250, and to reduce the frequency to 8. Both of these methods can bring the frequency to 2.0G, but the performance is not the same. Because FSB (FSB) is the channel that the system uses to communicate with the processor, it should be made as much as possible. So if the FSB is lowered to 100MHz and the frequency multiplier is raised to 20, there will still be 2.0GHz clock frequency, but the rest of the system and the processor communication will be much slower than before, resulting in system performance loss, so if the user's CPU can reduce the frequency multiplier, may wish to try!
The speed of FSB is usually closely associated with the speed of the front-end bus and memory. So when you raise the CPU FSB, the CPU, system and memory performance also increases, which is why DIYer like to overclocking.
Well, to go back to the BIOS setup, after you select the "Use Defined" option in "CPU operating Speed", you will see that the previously optional CPU option is now ready to be set!
1.ext.clock (CPU/AGP/PCI)
This is the FSB adjustment settings option, manually enter the number of CPU FSB you want to set, which allows you to enter a range of values between 100-412, you can increase the frequency per 1MHz for linear overclocking, maximum mining potential of the CPU. In general, the CPU FSB in 100 to 250 more normal, generally not more than 300MHz, so users should not be a one-time FSB to the highest, in principle, the first overclocking CPU because it is not clear how high the CPU can work under the FSB, So setting the FSB value can be increased from three to five MHz for steps to test slowly, here for demonstration, set the FSB directly to the standard FSB, set the correct FSB number, and then press ENTER to determine.
If the CPU frequency multiplier is not locked, pull the Ext.clock (CPU/AGP/PCI) menu will show a multiplier Factor (frequency multiplier setting) option this item selects the CPU frequency.
2.Estimated New CPU Clock:
This item shows the total frequency of the first two [Ext. Clock] and [multiplier Factor].
3. N/b Strap CPU as:
This section allows you to set up a front-end bus that is assigned to the MCH (memory controller). Options are: [PSB400], [PSB533], [PSB800], and [by CPU]. The default value is by CPU.
To manually set this part:
If the CPU frequency of 100MHz FSB, you can choose [PSB400].
If the CPU frequency of 133MHz FSB, you can choose [PSB533].
If the CPU frequency of 200MHz FSB, you can choose [PSB800].
4.DRAM Ratio (Cpu:dram):
This part can determine the frequency ratio between the CPU and the DRAM.
Here, we have to explain the relationship between the CPU and memory, the working frequency of memory is determined by FSB (FSB), so we have to CPU overclocking at the same time to the memory also increased the frequency of operation, set FSB and memory bus frequency ratio. If you are using DDR333 memory, its standard operating frequency can reach 166MHz, because we have already set the FSB to 133MHz, so we can choose "4:5", so that the memory also run at the highest frequency.
5. Fixed Agp/pci Frequency:
This project can be used to determine the frequency of the AGP/PCI bus, which allows you to maintain your AGP/PCI frequency on a number of fixed frequencies to improve system stability.
6. CPU Power Supply:
This option allows users to switch between the processor preset voltage value and the user-defined voltage value, and do not randomly change this preset voltage value unless you have some adjustment experience, select "user define" option "CPU Core voltage" You can select the voltage that the CPU core uses to allow you to manually select the core voltage value of the processor. As shown in figure:
Here is a brief introduction to CPU core voltage, P4 CPU rated core operating voltage of 1.5V, usually not more than 1.65V voltage is safe, of course, overclocking to improve the voltage is to ensure stable work under the premise of minimizing the voltage, this is from the thermal aspects of the CPU in order to control the temperature as low as possible. Voltage can also be a little bit of the gradual attempt to improve, do not need to rush to one-step, here we first choose 1.55V to try. Please note that more than 1.70V voltage for the North Wood core of the P4 is dangerous, it may burn the CPU, so the voltage should not be added too high!
7.DDR SDRAM Voltage:
This section allows you to select a DRAM slot operating voltage.
is to improve the DDR memory power supply voltage, the default voltage of the DIMM module is 2.5V, if the memory quality is not good, or overclocking the memory, then you can appropriately improve a bit of memory voltage, pressure range as far as possible do not exceed 0.5V, or it may damage the memory!
Finally, you can also see the option to increase the working voltage of the AGP display card, if you are overclocking for the standard FSB, also let the display Casue frequency work, then you can consider the appropriate increase in some AGP voltage, the AGP default voltage of 1.5V. As shown in figure:
Well, having said so many overclocking BIOS settings, continue to explain the BIOS settings for the other options, and of course, the content also has a description of how to optimize overclocking!
Two. Standard CMOS Features (standard CMOS parameter setting)
There's no need to talk about it! I guess we all can understand! The following is the "IDE device Settings" inside the option to explain, generally do not use user settings, to keep the default on it!
Three Advanced BIOS Features (BIOS advanced function setting)
1.Quick Power on Self Test (Quick Launch selection):
When set to [enabled], this project accelerates the application of post (power on Self Test) after the system is powered on. The BIOS shortens or skips some of the check items during the post process, speeding up the time to start waiting!
2.Hard disk boot Priority (hard drive boot sequence):
This item can select the priority of the hard drive to boot, press the button, you can go to its submenu, it will show the detected to allow you to choose the boot sequence of the hard drive, to start the system. Of course, this option will be installed in your two or more than two pieces of the system to choose!
3. HDD Change Message:
When set to [enabled], if the hard disk installed in your system changes, a prompt message will appear on the screen during post.
4. Boot device/second boot device/third boot device/boot other Device:
Select the first, second, and third sequence of devices to be turned on in the projects in [primary boot Device], [Second boot Device], and [third boot Device]. The BIOS will start the operating system in sequence according to the boot device you choose! The equipment you can choose depends on the equipment you have installed! As shown in figure:
Three. Advanced chipset Features (chipset setting)
Chipset setting is also a key setting in the BIOS setup, here is a detailed description!
1.DRAM Timing selectable (memory parameter setting option):
Depending on the memory module, this project sets the best timing for the next four items. The default value is "by spd". This default value reads the contents of the SPD (serial Presence detect) appliance and sets these four projects according to the SPD content. The EEPROM (read-only memory) on the memory module stores important parameter information about the module, such as memory type, size, speed, voltage interface, and module storage area.
2.CAS Latency Time:
This project controls the latency between the DRAM read instruction and the time when the data becomes truly available. A lower CAs cycle reduces the latency of memory to increase memory productivity. Therefore, as long as the operating system can be stabilized, we should try to lower the CAS parameters, so as to improve the running speed of memory. Conversely, if the memory is running unstable, you can set this parameter large to improve memory stability.
3. Act to Precharge Delay:
This project controls the number of DRAM frequencies used for DRAM parameters. Similarly, the value of small performance is high, but the quality of memory also requires strict!
4.DRAM ras# to cas# Delay:
This project can control the latency between the DRAM action and the read/write instruction, and there are several 2,3,4 options. The smaller the number, the better the performance.
5. DRAM ras# Precharge:
This project is used to control the waiting time for the frequency to start after the Precharge command is sent to DRAM. The smaller the pre charge parameter, the faster the memory reads and writes.
The above memory parameter settings generally can not move! Let the default be on, but overclocking players are definitely not going to miss anything that can improve performance, so if you want to let your computer improve a little bit of performance, you have to experiment slowly and choose an appropriate parameter to make your computer achieve the best performance and stability!
6.Video BIOS cacheable (video cache):
As with the system BIOS cache feature, the Enable cache feature of the imaging BIOS allows access to the image bios from c0000h to C7FFFH with cache, if the cache controller is enabled. The larger the size of the cache, the faster the image performance will be.
7.Memory Hole at 15m-16m (expansion card memory allocation):
When set to [enabled], there will be a 15m-16m memory space reserved for the ISA expansion card that specifically requires this setting. This will make the memory more than MB of space can not be used by the system, this project please use the system's default values.
8.Delay Prior to thermal (activation delay setting):
This project can be used to select the delay time before the action of the selective temperature probe (thermal) device.
9.AGP Aperture Size (AGP card slot memory allocation settings):
This project specifies the size of the system memory to be used by the AGP appliance, which is a portion of the PCI memory address range that can be allocated to the graphics memory space.
10.Init Display A:
This project can choose to initialize the AGP or PCI slot when the system is powered on.
[AGP]: When the system is powered on, it will initialize the AGP slot first.
[PCI Slot]: When the system is powered on, it will first initialize the PCI slots.
11.AGP Data Transfer Rate (AGP speed setting):
This project allows you to choose the data transfer rate of the AGP device, and the higher data transfer rate can provide faster and better graphics processing capability for your system. Verify that your display card supports the mode you have chosen. The majority of the cards bought now are 8X, generally with the default can be.
Four. Integrated peripherals (Integrated device setup)
This is the option to manage the computer's motherboard integration devices and ports, specific items because the motherboard is different, so the settings will be a difference, here is not explained in detail, just translate to the reader, each user when necessary, please follow the motherboard instructions to set, but in general, these settings are not necessary to adjust!
1.OnChip IDE Device:
2.OnChip PCI Device
1.OnChip USB Controller:
This option toggles the USB port on or off.
2. USB 2.0 Controller:
This option turns on or off the USB 2. Port transfer mode.
3.USB keyboard Support Via:
This project allows you to select [BIOS] so that you can use a USB keyboard in a DOS environment, or choose OS to use in an OS environment.
4.USB Mouse Support Via:
This project allows you to select [BIOS] to allow you to use a USB mouse in a DOS environment, or choose OS to use in an OS environment.
5.OnChip Audio Controller:
This option turns on or off the integrated sound device.
3.SuperIO Device:
4.Onboard Parallel Port:
Five. Wer Management Features (power management mode setting)
Oh, there is no need to say more! I can understand it! Everyone can set these power management options according to their own preferences! Just to introduce "CPI Suspend Type"
Six. PNP/PCI configurations (PNP/PCI configuration set)
1.Resources controlled by:
This project can perform configuration actions for all power on and plug-and-play compatible devices.
[Auto]: The system will automatically detect all settings.
[Manual]: Select a specific IRQ resource in the "irq resources" menu.
2.IRQ Resources:
This project may set the interruption of individual systems to either [PCI Device] or one in [Reserved].
3.PCI/VGA Palette Snoop:
This project will determine which MPEG Isa/vesa VGA cards can (or cannot) work with PCI/VGA.
[Enabled]: MPEG Isa/vesa VGA cards can work with PCI/VGA.
[Disabled]: the MPEG Isa/vesa VGA card does not work with PCI/VGA.
Seven. PC Health status (computer health settings)
Here the specific settings are not much to say! The previous AMI BIOS setup article has been described in detail! There are a number of other COMs settings here is no longer, are some very simple settings, everyone just look at my Chinese interpretation can understand.
BIOS setup Illustrated tutorial on AMI Chapter
(Currently the main motherboard of the BIOS mainly for AMI and award two series, how to identify the BIOS brand series please, this article explains the AMI series of BIOS setup diagram tutorial, if your BIOS for the award series Please go to "BIOS Setup Illustrated Tutorial Award Chapter", The important part of the article has been marked red, fast reading please cooperate with the picture check red speed font can be
For many beginners, the BIOS setup is a very headache thing, facing the full screen of E, it is impossible. However, set the BIOS in the eyes of the master, but nothing.
When you look at the master's fingertips on the keyboard skilled beat, and the blue screen characters are constantly changing, you must be very envious, isn't it?
In fact,BIOS settings are not particularly mysterious , but why do beginners have such a headache? According to induction, summed up a number of reasons, I hope beginners can avoid being swayed by these factors.
I heard people say it's dangerous to operate the BIOS.
Here, I do not deny that the operation of the BIOS has a certain risk, the BIOS is basic Input Output
System abbreviation, is the basic input/output system meaning, that is, the computer's most basic boot system, if the BIOS setup error, the hardware will not work properly.
Is it really dangerous to operate the BIOS?
I hear a lot of friends are saying, set the BIOS is very dangerous, from a person to contact the computer began, was the predecessor of the BIOS in a layer of mysterious veil. Can say that almost everyone knows set
The BIOS is a very dangerous operation, and it is because of this, the rookie can not easily try. But if you don't try, you'll never learn how to set it up. Therefore, in this I suggest, again dangerous things we also want to try, dare to try to be a rookie to become a master of the necessary psychological quality.
No confidence when you see the English-language interface
A lot of rookie to see Mansi English, there is no set of confidence, is not willing to look at the content, so naturally will not go to in-depth study. But in fact, there are many settings in the BIOS English is very simple, in the school English is not particularly poor people, are basically able to understand the general effect, do not know also do not have to debug, after all, the BIOS is often modified in so many projects. Therefore, when you enter the BIOS, do not be in the full screen of the E-text intimidated , so as to slowly learn to train the BIOS.
be used to asking for help from others
Rookie and Master in the early days is no difference, but rookie in the face of the problem, turn to others to help fix, but the master likes to query their own information. Setting the BIOS is the same, many people use the computer for 10 years, do not know how to set the first boot device in the BIOS setup, causing even the operating system will not be installed. Apparently, 10 years later, he's still a rookie. And like to study the master, presumably in the computer for half a year, will be familiar with the installation of various operating systems, debugging the most basic BIOS. It is not exaggerated to say that the author in the use of computer three months later, has already known dozens of DOS command (the author from the win 3.1 times use the computer).
Baidu, Google are a good helper to solve the problem
In the daily use of the computer is the same, such as the computer suddenly popped out a false hint, rookie and master performance is completely different. In general, the rookie is directly off the error prompts, waiting for the computer to restart, or waiting for someone to help him solve. And the master will be wrong tips copied down, to Baidu, Google search error prompted content, seek solutions. This is the master and rookie the biggest difference, so rookie want to become a master, must find their own data to solve problems, or other people to help solve the time to ask why to do so , rather than drinking coffee aside.
If you have a personal computer for more than 3 years, is still a rookie words, I believe you will have the above mentioned problem exists, need to pay attention to! Today, we want to talk about the main content is rookie how to tune the BIOS, as long as you carefully read this article, you will find that the BIOS is not so mysterious, it is not so dangerous.
What is BIOS?
BIOS is English "Basic Input Output
System "abbreviation, the Chinese name is" basic input and output system "after literal translation. Its full name should be Rom-bios, which means read-only memory basic input and output system. In fact, it is a group of curing to the computer motherboard on the previous ROM chip program, it holds the computer's most important basic input and output of the program, system settings information, power-on on the Self-Test program and the system to start the bootstrap process.
Its main function is to provide the lowest, most direct hardware setup and control for the computer.
BIOS Setup program Interface
What is the difference between the BIOS and the CMOS?
CMOS (Complementary metel-oxide
Semiconductor) is an abbreviation for complementary metal oxide semiconductors. It is meant to be a technology used in the manufacture of LSI chips or chips made from this technology. This usually refers to a read-write RAM chip on the computer's motherboard. It stores the real-time clock information and hardware configuration information of the computer system. When the system is booting the machine, it reads the CMOS information to initialize the state of each part of the machine. It relies on the system power supply and back-up battery to power, the system will not lose the power of information lost.
Cmos
RAM storage Device
Since the CMOS and BIOS are closely related to the computer system settings, there is the idea of CMOS settings and BIOS settings. As a result, beginners often confuse the two. Cmos
RAM is where the system parameters are stored, and the System Setup program in the BIOS is the means to complete the parameter setup. Therefore, the accurate statement should be through the BIOS setup program to set the CMOS parameters. What we normally say about CMOS settings and BIOS settings is its simplified version, which in some ways creates confusion between the two concepts.
In fact, the BIOS program is stored in the CMOS memory, CMOS is a semiconductor technology, can be a pair of metal oxide semiconductor field effect transistor (MOSFET) integrated on a piece of silicon. This technique is commonly used in the production of RAM and switching applications, and the products produced by it are very quickly consumed with very low power consumption and have a high tolerance for interference with power supply. Specifically to us this refers to the computer host board a special RAM chip, this small block of RAM is usually 128k bytes or 256k bytes, but now with the development of the computer, this RAM capacity is also increasing, many motherboards are currently using 2M or even 4M of memory. Of course, the role of CMOS RAM is to save the hardware configuration of the system and user settings for certain parameters.
If you do not understand, then the simplest to tell you that the BIOS is a set of procedures, can be understood as software, and CMOS is a memory chip.
Why is it dangerous to set up a BIOS?
As we said earlier, CMOS has the most basic information of computer equipment, that is, the lowest level of information, and the BIOS setup program is to regulate these low-level information. The BIOS setting directly determines the work of the hardware and is a set of programs that deal directly with the hardware. The operating system needs the BIOS to control the hardware, so the BIOS can be understood as a bridge between the hardware and the operating system, so the BIOS setting is really dangerous because of the direct control of the hardware.
What are the main functions of the BIOS?
Self-Test and initialization:
After the boot, the BIOS is first started, and then it will be the computer hardware equipment for complete and thorough test and testing. If the problem is found, it will be handled in two cases: a serious outage, no hint or signal, or a ScreenTip or sound alarm signal, waiting for the user to process. If the problem is not found, set the hardware to standby, and then start the operating system to give control of the computer to the user.
Program Services:
The BIOS directly deals with the computer's I/O (input/output, input/output) device, sends commands through a specific data port, transmits or receives data from various external devices, and realizes the direct operation of the software program to the hardware.
Set Interrupt:
When the boot, the BIOS will tell the CPU the hardware device interrupt number, when the user issued instructions to use a device, the CPU based on the interrupt number using the corresponding hardware to complete the work, and then jump back to the original work according to the interrupt number.
BIOS type and motherboard BIOS branding
Due to the BIOS on many devices, the BIOS is also very diverse, except for the motherboards we know, graphics cards, televisions, DVD players and other devices will have BIOS programs and related CMOS hardware. But what we are talking about today is the bios of the motherboard, not too far from here.
From the present point of view,
Motherboard BIOS has two main brands, award and Ami, some friends may see the Award-phoenix bios, in fact this is the award program, because Phoenix has been award acquired. On some servers or workstation computers, we often see Award-phoenix bios programs.
Award BIOS Program Interface
AMI BIOS Program Interface
The most accurate way to distinguish a motherboard from a award BIOS or an AMI BIOS is to look at the relevant fields in the BIOS interface. But for the rookie, there is a simpler way to differentiate: The BIOS program Interface is blue-white, usually award BIOS program, and the BIOS program interface for Gray-bottom blue word, is generally an AMI BIOS program (as shown above). Today, our main focus is to tell you about Ami.
Some settings in the BIOS.
First, let's take a look at the contents of the first menu main:
In this menu, there is actually no particularly important information, the first is to adjust the system time, the second is to adjust the system date, in fact, both of these steps can be operated in Windows.
We see the third line of the menu legacy diskette A, which is an option to configure the floppy disk drive. You can choose the type of floppy drive you have here, such as 1.44M
3.5in. Of course, at present, more than 80% of the users do not need to install the floppy disk drive, the use of the floppy drive is also getting lower, the USB disk almost replaced everything. For
A computer without a floppy drive, set here to Disabled, turn off the floppy drive detection.
Further down the menu, there are four SATA configurations, which are actually directly related to the SATA interface on the motherboard. Generally speaking
SATA
interface can be automatically identified to the device installed on this port, so there is very little need to set it, of course, do not rule out special circumstances.
Sataconfiguration literally means to understand the SATA configuration, which is the interface that goes directly into this project. Here, we can adjust the SATA working mode on the motherboard, or even turn off the function of SATA interface.
SATA working mode is generally divided into two types: compatible and enhanced, from the Chinese meaning to understand, that is, "Compatibility Mode" and "enhanced mode", what exactly does that mean?
A lot of friends are having Windows 98 installed, Windows
Me, Linux system, there is no hard to find the situation, in fact, this is the SATA mode of work is not adjusted well. In general, some older operating systems for SATA hard disk support is very low, before installing the system, be sure to set the SATA mode to compatible. Compatible mode when the SATA interface can be directly mapped to the IDE channel, that is, SATA hard disk is recognized as an IDE hard disk, if the computer also has a PATA hard drive, you need to do the relevant master and slave disk jumper set. Of course, the enhanced mode is enhanced mode, with each device having its own SATA channel, not occupying the IDE channel, for Windows
XP installation of the operating system above.
The following is a hard drive write protection settings, where the main set is to prevent the BIOS to the hard disk, in fact, is to guard against the famous CIH virus many years ago. But now there are very few bios viruses, so hard drive write protection is not useful, suggested disabled.
Return to main main menu,
the last project is System Information, this project is actually not useful,
to see some basic configuration of the current computer。 such as CPU model, frequency, number of threads, memory capacity, and other information.
Because there are so many items in the Advanced menu, if one of the words is a waste of time and space, and many of the settings are not useful, we mainly talk about the focus of the Advanced menu.
When we select this menu, we can see several major sections of the above advanced.
Jumperfree
Configuration (free jumper configuration)
The first item is an ASUS motherboard specific project, Jumperfree, translated into Chinese is free jumper meaning. So, this project is a jumper-free setup item. However, the products introduced by other manufacturers are basically the project, but the name is generally not called Jumperfree configration.
After entering the Jumperfree configuration, you can see the interface as shown above, with a very wide range of content. Let's look at what they mean by the first number:
Ai overclock tuner--asus Artificial Intelligence overclocking (recommended set to Auto)
CPU ratio setting--cpu frequency setting (recommended to auto, overclocking required)
FSP Strap to North bridge--ASUS Special frequency modulation (recommended value auto)
Some of the following DRAM-related items are all tuned to memory, and if not overclocking, these recommendations are set to auto status.
Looking down, we can see the adjustment of the CPU, north-South Bridge, memory and other equipment voltage items, these are to be used in the overclocking. There is not much to tell.
Jumperfree
Configuration's content has been introduced, we then look at the contents of the USB conguration.
USB Configuration (USB configuration)
There is not much content in the USB conguration, where the USB
Functions is the project that configures whether USB function is turned on, for the ordinary user, of course should turn on this function. But the Internet café machine, here should choose disabled.
The second is the USB 2.0 controller adjustment, if you choose the Enabled,usb interface will work in the USB 2.0 transmission mode, if the disabled, it will be degraded to USB 1.1, the speed will be much slower. Presumably the vast majority of users will be enabled by this bar! The next one is the USB 2.0 controller operating mode, with both high speed mode and full speed mode, but this is not very significant.
Items fourth and fifth are of little use to ordinary users, and keeping the defaults is good.
The sixth item is a little bit important, Legacy USB
Support, translated into Chinese can be understood as "traditional USB device Support", this must not be set to disabled, no one you connect to the USB keyboard can not be recognized in the BIOS and DOS. It is recommended to choose Auto, which is turned on when the computer is connected to a traditional USB device, otherwise it is automatically turned off.
CPU Configuration (CPU configuration)
Next we return to the main menu and go to the CPU Configuration page:
CPU Configuration page for ordinary users, not much use, the first is set CPU frequency, which in the Jumperfree
Configuration is already there, overclocking players can use.
Some of the other options are not very useful, and the last item is
Intel's well-known SpeedStep technology, if this technology, you can realize the CPU in idle time automatically reduce frequency, thereby saving electricity,Laptop users are strongly recommended to turn on this option.
Chipset (chipset)
Since the North Bridge chip related settings have been in the Advanced menu of Jumperfree
Configuration in the end, so
The main chipset here is the configuration of the South Bridge chip.
But here we often adjust only the second item, Initiate Graphic
Adapter, Chinese meaning is starting from what graphics card. That is, when we have a PCI video card in our computer and a PCI-E video card in the same time, let that piece of graphics work to boot the system. In general, the adjustment item here in the consolidated motherboard is pci-e/on board, i.e. booting from a stand-alone video card or from an integrated video card.
onboard Devices Configuration (onboard equipment configuration)
This menu is mainly about the integration of some devices on the motherboard, including sound card, network card, 1394 controller and other devices. One day, you suddenly found that the sound card disappeared, or the network card disappeared, then you should come to the BIOS to see if this is blocked. The image above is adjusting high-fidelity audio, if you do not have an independent sound card, choose enabled.
The Front Panel type is about the types of front audio, which can be set to AC 97 or HD Audio. If your home does not have more than 5.1 channels of audio equipment, it is recommended to set the AC97, because the audio before and after is independent. If you choose HD Audio, the front audio can only be used as two small speakers in the 5.1-channel system.
The author tested this ASUS P5K/EPU motherboard, because of the use of P35 chipset, the bridge chip does not provide direct IDE support. However, Asus P5K/EPU uses an IDE control chip provided by the Marvell Company, which provides support for an IDE interface through this chip. If you do not have an IDE hard drive or optical drive, you can choose to disabled this option.
The next item is the Marvell Gigabit NIC Controller setting, which is recommended to be enabled unless you have a stand-alone network card with more robust performance.
PCI/PNP
The next item in the main menu is the PCIPNP configuration, mainly to the hardware interrupt request manually assigned, set slightly improper, may cause the hardware can not run, the non-senior users recommend not to try, this part of the content we also skipped.
There are so many items in the Advanced menu that it's important to write two pages. Let's take a look at some of the key items in the Power menu.
The first item in the Power menu is the suspend mode, and for the PC it is recommended to choose S3
Only or auto, and for POS machines, it is recommended to select S1.
Several other items can be kept at the default value, but the author is here to mention the ACPI APIC
Support this one. A lot of people have met,
the point of shutting down in Windows
after the computer is logged off, but it does not shutdown, you must press the power switch again, the computer will be closed. If this is the case, then 80% of the above is due to not open the ACPI APIC support, so this item must be opened.
P.S. ACPI is the meaning of advanced power management.
APM Configuration
Many friends have encountered such a problem, that is, as long as a plug in the power cord, the computer will automatically boot , for the rookie, to solve this problem looks difficult, in fact, otherwise. in the BIOS power, there is the restore on AC power loss, which can actually fix the problem above.
Let's take a look at the Chinese meaning of the restore on AC power loss , which can be understood when the disconnected AC source is restored to the age state. The main function here is, when the computer is not normal power, after the current recovery, the computer will be in what state. There are three options:
Power off (when the current is restored, the computer is in the shutdown state)
Power on (when the current is restored, the computer is in the power-on State)
Last state (most recent status, i.e. state when power is lost)
If you really understand the friend of restore on AC power loss, I'm sure I've learned why it's automatically turned on when you plug in the cord computer, which is because it's chosen to be on, and of course you might be able to do that with the last state. If you are still bothered by this problem, then you can solve it now.
The following items are some boot method settings, such as a regular boot, remote modem control boot, PCI device control boot, keyboard boot, mouse boot and so on. Use the same method all the same. Here we take the keyboard to boot as an example of the knowledge here. The keyboard is powered on by using one of the keys on the keyboard to turn on the computer, without having to press the power button on the front of the chassis. To enable the keyboard to boot, not only the motherboard to support the keyboard to boot, and the keyboard must also support this feature. Fortunately, almost all motherboards now support this feature, and most standard keyboards can support this feature. It is also very important that both the keyboard and mouse boot can only support the PS/2 interface products, USB interface Keyboard Mouse is not supported.
The image above is the keyboard boot of the Setup interface, here are 3 options, respectively, are
space Bar (SPACEBAR), Ctrl-esc,power key (the Power key on the keyboard). When you select the corresponding (combination) key, the next time you open the computer can be directly through the corresponding button to open.
In general, the Power menu also has a hardware monitoring page, this page shows the current CPU, motherboard and other equipment temperature, voltage, fan speed and so on, in some cases can also be ruled out some fault.
The boot menu is the most common use of the menu, which is mainly configured for various boot items. Let's take a look at the important features in the boot menu:
There are three submenus below the boot menu, and the contents of these three menus are very useful. Let's look at one of them!
boot Device Priority (priority boot device)
in this project, you can set the system priority from which device to boot. 1st boot device is naturally the first boot device, 2nd boot device is naturally the second boot device, and so on. If you want to use the CD to install the system, here is the need to 1st Boot Device
set to the optical drive, as shown above, the menu to find the type of CD-ROM you are using, if you want to boot the system from the hard drive, then you need to set the hard drive to 1st boot
Device, such as the hdd:pm-st3160811as in the figure above, Seagate 160G hard drive.
Later install the system, no longer need to ask someone else to help you adjust the BIOS it!
Boot settings conguration (boot setup configuration)
In the Boot Settings conguration menu, the most used is waiting for "F1" if Error, and full screen Logo.
Full Screen LogoThe role is to turn off/Open the Power-on BIOS full-screen screen (such as the above), has enabled and disabled two options, enabled to open Full-screen screen, disabled is turned off the boot logo.
There is a wait for "F1" if Error, I believe many people have encountered the open computer must press the F1 key before you can start the computer , in fact, is here. If you encounter every boot need to press F1 to enter the computer, but not sure what is the problem, you can set this to disabled, the problem is resolved.
The third menu mainly set the power-on password, which is very simple, here is not to say more.
Because the Tools menu is the manufacturer's own some of the tool software added, here we will not say more. Let's look directly at some of the setup items in the Exit menu:
The Exit menu has four items, from top to bottom:
Exit & Save changes--Save settings and exit
Exit & Discard changes--do not save settings and exit
Discard changes--Only undo changes, do not exit
Load Setup defaults--load default settings
At the same time, to say a save and exit the simplest way, in the BIOS setup interface to press F10, and then press Y, do not believe you try!
At this point, the AMI BIOS key settings are introduced, if you read the article carefully from beginning to end, I believe you can learn a lot of things. Of course, after reading the article, be sure to enter your computer's BIOS settings interface, to practice, this can get rid of every time the BIOS setup requires someone else's dilemma.
