【 Weak current College 】 BIOS optimization completely---Power By 【 China power house network 】

<br> <br> Full BIOS optimization <br> I. STANDARDCMOSSETUP (standard CMOS Setup) <br> Here are the most basic of CMOS (ComplementaryMetalOxideSemiconductor, complementary metal oxide semiconductor) system settings, including date, drive and display adapters, the .most important one is the halton: System hangs settings, the default setting is expressed in the POST AllErrors (PowerOnSelfTest, power-on self test) any errors in the process will stop start, this selection will ensure system stability. If you want to speed .it up, you can leave it set to NoErrors, that is, at all times to complete the boot, but accelerated consequences is likely to cause a system error, press Select. <br> 1, DriveA / DriveB <br> Options: 360K ., 5.25in; 1.2M, 5.25in; 720K, 3.25in; 1.4M, 3.25in; 2.88M, 3.25in <br> Set the appropriate drive, and if you do not have the appropriate hardware to set to None, you can .improve system speed test. <br> 2 Video (video) <br> Options: EGA / VGA, Mono (black and white monitor) <br> Set to EGA / VGA, don't try to Mono, slows boot speed. < .br> Second, BIOSFEATURESSETUP (BIOS feature equipment) <br> 1, VirusWarning / Anti-VirusProtection (virus alerts / anti virus protection) <br> Option: Enabled (on), Disabled (off), ChipAway (chip control) <br .> This setting prevents external program to launch area and the hard disk partition table writes, when a write operation, the system automatically generates a warning and prompts the user to interrupt program execution. It does not protect an entire hard drive, but also for the .operating system installed (for example WINDOWS95/98) and some disk diagnostics, even on the BIOS upgrade that may produce unnecessary conflicts caused by the interruption of the program. Recommend users to turn off this option, the system of values is Disable. <br .> Some motherboards since with antiviral kernel, it can provide higher than regular virus warning higher level of defence, however, when used with peripheral controller BIOS (such as SCSI card or UltraDMA66 controller), boot sector viruses can bypass the system BIOS to make attacks ., protection will be completely dead. <br> 2, CPULevel1Cache/InternalCache (central processor level cache / internal cache) <br> Option: Enabled, Disabled <br> This setting is used to control the CPU's primary cache on / off, L1Cache .on the machine's overall performance has a great effect, close after system performance will drop several orders of magnitude. In overclocking, L1 cache is often the key to success, such as you can't hyperlink to 500MHz, does not mean that the CPU cannot .500MHz, most likely L1Cache cannot achieve, so close level caching can improve the success rate of overclocking. <br> 3, CPULevel2Cache/ExternalCache (CPU L2 cache / external cache) <br> Option: Enabled, Disabled <br> This setting is .used to control the CPU's primary cache on / off, it systems and overclocking of like L1 cache, close L2Cache success rate can also be overclocked. <br> 4, CPUL2CacheECCChecking (CPU L2 cache ECC checking) <br> Option: Enabled, Disabled .<br> The system can enable CPU internal L2Cache for ECC (error checking ErrorCheckingandCorrection, amended) detection, the default value is Enable, it can detect and correct the units keep the signal the error, the accuracy of the information on overclocking stability help, .but cannot detect double-bit signal errors. Here it is important to note that enable ECC detection will delay system post time and reduce the machine's performance, but must be open this memory support. <br> 5, QuickPowerOnSelfTest (quick power on self test .) <br> Option: Enabled, Disabled <br> This setting can accelerate the speed of the system post, so that the system to skip certain post options (such as memory full detection), but after opening would reduce the ability to weaken the .multi-monitor systems *. <br> 6, BootSequence <br> Option: A, C, SCSI / EXT <br> C, A, SCSI / EXT <br> C, CD-ROM, A <br> CD-ROM ., C, A <br> D, A, SCSI / EXT (at least two IDE hard disk only occurs) <br> E, A, SCSI / EXT (at least three IDE hard disk only occurs) <br> F, A ., SCSI (at least four IDE hard disk only occurs) <br> SCSI / EXT, A, C <br> SCSI / EXT, C, A <br> A, SCSI / EXT, C <br> LS / ZIP, C .<br> This setting determines the system boot drive letter, if you want to speed up the system post speed can be set to (COnly), the system no other drive post and go directly to the primary boot drive. Some motherboards (eg ABITBE6 .and BP6) have additional IDE controller, you can access the third or fourth group IDE device, then you should select the EXT start priority. <br> 7, BootSequenceEXTMeans (the startup order of EXT definition type) <br> Options: IDE and .SCSI <br> When you use EXT devices, define the type of device used, including (IntegratedDriveElectronics, integrated drive electronics) and SCSI (SmallComputerSystemInterface, small computer system interface). <br> 8, SwapFloppyDrive (swap floppy drive letter) <br .> Option: Enabled, Disabled <br> Swap disk drives, floppy disks for different formats. When the system installed 2 floppy, if set to Enabled, the system will take the B drive as the startup disk, if it is set to Disabled, .on the contrary. <br> 9, BootUpFloppySeek (startup looking for floppy disk drives) <br> Option: Enabled, Disabled <br> Test the floppy drive when powered on the existence of, and to check its track number is 40-or .80-track, General 360K are 40 track, while 720K/1.2MB/1.44MB is 80-track. The default value is Enable, note: when the number of tracks is the floppy disk drive 80 tracks, the BIOS and cannot distinguish between .their respective types. <br> 10, BootUpNumLockStatus (startup Keyboard NumLock key State) <br> Options: on, off <br> Control keypad on / off status, have no effect on performance. <br> 11, GateA20Option (A20 address .line selection) <br> Options: Normal (normal), Fast (faster) <br> Settings which control unit management above 1 MB memory address A20 address line, set to Normal keyboard controller management, is set to Fast with chipset controller management can .improve memory access speed and overall system performance, especially for OS / 2 and Windows and other operating systems are very effective. Because of their protected mode often need BIOSA20 address line to toggle, and chipset controller faster than keyboard controller, so Fast is the preferred .setting. <br> 12, IDEHDDBlockMode (IDE hard drive block mode) <br> Option: Enabled, Disabled <br> Previous hard disk access patterns is one sector, block mode multiple sectors a block, each time you access several sectors, can .increase the number of sectors access data transfer rates. Turn on this feature, the BIOS will automatically detect the hard drive has supported block mode (today's most hard disk already has this feature), and each interrupt can be issued once 64KB information. If you .use WindowsNT system, we must be careful, it does not support block mode, it may result in data transfer error occurs, so Microsoft recommends WinNT4.0 users close the IDE hard drive block mode. To turn off this feature, each issued only interruptions .once 512Byte information, reducing the overall performance of the disk. <br> 13, 32-bitDiskAccess (32-bit disk access) <br> Option: Enabled, Disabled <br> In fact, 32-bit disk access is not a true .32-bit transmission, but with the IDE controller and two 16-bit operations. On the PCI bus, at the same time be able to transfer data, the more the better, so leave a 32-bit transmission can also increase your system performance .. WindowsNT system does not support 32-bit disk access is likely to result in data transfer error occurs, so Microsoft recommends WinNT4.0 users to turn off this feature, of course, 16-bit is in any case also fast but a 32 - .bit. <br> 14, TypematicRateSetting (input speed settings) <br> Option: Enabled, Disabled <br> Whether to use manual settings to control the input speed, so if you want to speed up word processing efficiency, or open, only .Enabled before you can adjust the input and the input delay. <br> 15, TypematicRate (Chars / Sec) (input rate, unit: characters / second) <br> Options: 6, 8, 10, 12, 15, 20, .24, 30 <br> In seconds the number of characters for input, the higher the value, the faster speed. <br> 16, TypematicRateDelay (Msec) (input delay unit: milliseconds) <br> Options: 250, 500, 750 ., 1000 <br> Each input character delay time value smaller faster. <br> 17, SecurityOption (security option) <br> Option: Setup System, <br> As long as established in the BIOS password, this feature will be turned on ., set to System, the BIOS on every time you start will enter the password that is set to Setup, in the enter the BIOS menu require a password. If you don't want to fiddle with your machine, or with a password. < .br> 18, PCI / VGAPaletteSnoop (PCI / VGA color version detection) <br> Option: Enabled, Disabled <br> This property is used only for the graphics card interface attach devices, such as MPEG daughter card, etc. By tinting version .detection can correct frame buffer of data, and can be synchronized to the additional equipment and main display cards, avoid adding caused a black screen after the daughter card. <br> 19, AssignIRQForVGA (to VGA device assigned IRQ: INterruptRequest, interrupt request) .<br> Option: Enabled, Disabled <br> At present, many of the high-end graphics card requires IRQ to increase the exchange of data with the motherboard, turn on after the speed significantly improves overall performance. In contrast, low end graphics .card does not need to assign IRQ, video manual has instructions if it is call interrupt, without interruption benefit is save system resources. <br> 20, MPSVersionControlForOS (object-oriented operating system MPS version) <br> Options: 1.1, 1.4 < .br> It is designed for multiple processor board, is used to determine the MPS (MultiProcessorSpecification, multi processor specification) version, so as to allow PC manufacturers build based on the Intel architecture for multiprocessor systems. Compared with standard 1.1 1.4 added extended structure table .that can be used for multiple PCI bus, and on future upgrades very favorable. In addition, v1.4 has second PCI bus, also without PCI bridge connection. New SOS (ServerOperatingSystems, server operating systems) are mostly support 1.4 standards, including the .WinNT and LinuxSMP (SymmetricMulti-Processing, symmetric multi-processing architectures). If you can, try to use v1.4. <br> 21, OSSelectForDRAM> 64MB (operating system what to do with more than 64 MB of memory) < .br> Options: OS / 2, Non-OS / 2 <br> When the memory size is larger than 64MB, IBM OS / 2 system to manage memory, if you don't use OS / 2, set to "Non-OS ./ 2 ". <br> 22, HDDS.MARTCapability (hard disk SMART capabilities) <br> Option: Enabled, Disabled <br> SMART (Self-Monitoring, AnalysisandReportingTechnology, automatic monitoring, analysis and reporting technology) is a hard disk .protection technology, open can increase system stability. <br> In a network environment, SMART may automatically send some packets without supervision to your hard disk, they are not allowed by the operating system, often leading to system restart. If you intend to put .the computer as a network server, it is best to turn off this feature. <br> 23, ReportNoFDDForWin9x (for Win9x report could not find the floppy disk drive) <br> Option: Enabled, Disabled <br> In the absence of FDD .(FloppyDiskDriver as a floppy disk drive) of the machine, turn off this option and the FDC IntergratedPeripherals (FloppyDiskController, floppy disk drive controller) option, you can release the Win9x IRQ6, saving system resources. <br> 24, DelayIDEInitial (Sec) .(delay IDE initialization, seconds) <br> Options: 0, 1, 2, 3, ...,< br> Today the BIOS boot much faster than before, when the device detection, some legacy IDE device may not start, in .order to adapt to this situation, the BIOS provides a delay option, you can slow down the startup time. Set to "0" is the fastest, the BIOS will ignore IDE device initialization failed, started directly. <br> 25, ProcessorNumberFeature ( .processor number feature) <br> Option: Enabled, Disabled <br> Dedicated Pentium III serial number-type processor, such as, you can read through some of the special program, provides a security guarantee. In fact, this type of protection levels .are relatively low, it is easy to be someone special edition and made an attack, or closed. <br> 26, VideoBIOSShadowing (video BIOS mapping) <br> Option: Enabled, Disabled <br> Video card do each job must pass through .CPU processing data, or even some hardware and hardware Exchange (such as display chip and display memory), or you want to use to the central processor. In order to improve the speed, the first solution is to increase the BIOS chip, extend the .system BIOS functions to manage your video card. Turn on this feature can be part of the video BIOS to copy the contents of system memory to speed up the access speed. In traditional computers, the CPU via 64-bit DRAM bus reading data than the .8-bit XT bus much faster, can greatly improve the performance of the display subsystem. However, modern video card already contains a processor chip, all work done by the display processor, and driver's special instruction and direct communication, in the CPU to increase .speed, also provides backward compatibility. In addition, most operating systems (such as: WinNT4.0, Linux) can bypass the BIOS operation hardware, BIOS mapping is not useful, it would be a waste of main memory space or cause system instability. .<br> By the way, most of the video card is FlashROM is EEPROM (electrically erasable ElectricallyErasableProgrammableROM, programmable read only memory), and they not only legacy 130-150nsEPROM quickly, even beyond the DRAM, and so video BIOS mapping becomes meaningless. .<br> If you insist on using a mapping, you should put all the regional map, not only the default copy a diaryValue (C000-C7FF), avoid BIOS capacity conflicts caused by excessive. Video BIOS mapping only benefit is compatible with the DOS .games, those who are behind the times does not have direct access to hardware, BIOS help is not. <br> 27, Shadowingaddressranges (xxxxx-xxxxxShadow) (mapped address column) <br> Option: Enabled, Disabled <br> This option .controls the one area of memory will be used to map the video BIOS. Note that some additional card will use CXXX-EFFF as input / output, and the memory read / write requests will not be executed after the ISA bus, mapping video BIOS may .cause additional card does not work. <br> III. ChipsetFeaturesSetup (chipset features Setup) <br> 1, SDRAMRAS-to-CASDelay (memory line addresses controller-to-column address controller delayed) <br> Option: 2, 3 < .br> RAS (row address RowAddressStrobe, controller) to the CAS (column address controller ColumnAddressStrobe) delay time between.
