The answer is that I turned it over
BLOS is a basic input and output system (basic input &; Short for output system. The so-called basic input and output system is a necessary condition for starting the computer normally. When starting the computer, the CPU should first check whether the basic equipment is normal according to the BLOS chip integrated on the motherboard, graphics card and other equipment, and then proceed to the next step. By rewriting BLOS settings in computer analysis, the performance and compatibility of equipment can be improved. Because BLOS is very important, once BLOS makes a mistake, the consequences are quite serious. Bonus BIOS Settings and Basic Options Standard CMOS Settings are used to set the date, time, software and hard disk specifications, work type and display type. BIOS function setting (BIOS is used to set special functions of BIOS, such as virus warning. Chipset feature settings are used to set parameters related to CPU operation, power management settings are used to set power-saving functions, and PNP/ PCI configuration is used to set interrupts and other differences between ISA and other plug-and-play devices (loading BIOS default values). This option is used to load the initial BIOS settings (load the motherboard BIOS factory settings), which is the most basic BIOS settings. , used to determine the fault range. Integrated peripheral (built-in integrated device peripheral setting) Motherboard integrated device setting supervisor password (administrator password) Computer administrator setting enters BIOS to modify setting password user password (user password) setting boot password IDE HDD automatic detection (IDE hard disk type automatic detection) is used to automatically detect hard disk capacity and type storage &; Exit Settings Save the changed settings and exit BIOS Settings Without Saving Exit without saving the changed settings and exit setting standard CMOS settings, including date and time settings. You can set the time and date on your computer here. The following are the hard disk settings, and the first group of IDE master devices of PRIMARY MASTER exist in the list; A first group of IDE slave devices; The second group of IDE master devices; The second group of IDE slave devices. The IDE devices here include IDE hard disk and IDE CD. The first and second groups of devices refer to the first and second IDE data lines on the motherboard. Generally speaking, the first group of IDE devices is close to the chip, and the master device and slave device refer to two devices connected on an IDE data line. As we all know, each data line can be connected to two different devices, and the master device and slave device can be adjusted through the jumper behind the hard disk or optical drive. Secondly, the types and hardware parameters of IDE devices. TYPE is used to explain the types of hard disk devices. We can choose three working modes: automatic, user and none. AUTO is the hard disk type detected by the system itself, and the hard disk parameter of 1-45 is stored in the system, so it is unnecessary to set other parameters when using this setting value. If the hard disk we use is not predefined, then we should set the hard disk type to USER, and then input the actual parameters of the hard disk (these parameters are generally on the surface label of the hard disk); If there is no IDE device installed, we can choose the NONE parameter, which can speed up the startup of the system. In some special operations, we can also shield the system from automatically checking some hard disks. The size represents the capacity of the hard disk; Number of cylinders of CYLS hard disk; Number of magnetic heads of the hard disk; PRECOMP writes the pre-compensation value; LANDZ landing zone, that is, the head start-stop sector. The last mode is the working mode of hardware. The working modes we can choose are: normal normal mode, LBA logical block address mode, large hard disk mode and AUTO automatic selection mode. Normal mode is the original IDE mode. In this mode, you can access the hard disk BIOS and IDE controller to make any conversion to the parameter department, and the maximum supported capacity is 528MB. The maximum hard disk capacity managed by LBA mode is 8.4GB, and the maximum capacity supported by large mode is 1GB. Automatic mode is the working mode in which the system automatically selects the hard disk. The other part is the floppy drive settings of drive A and drive B.. If there is no drive b, there is no drive b setting. We can choose our floppy drive type here, of course, in most cases we don't have to modify this setting. The video setting is used to set the working mode of the monitor, that is, the EGA/VGA working mode. HALT ON this is the error stop setting, all errors BIOS: it will stop when any error is detected; No error: when the BIOS detects any non-critical error, the system will not stop; Everything except the keyboard: except the keyboard error, the system will stop if it detects any error; Everything except the disk: except the error of the disk drive, the system will stop when any error is detected; Everything except the disk/keys: Except the errors in the disk drive and keyboard, the system will stop when any errors are detected. Used to set the shutdown mode when there is an error in the system self-test. If the above error occurs, the system will stop starting and give an error prompt. There are also parameters of system memory: basic memory: basic memory; Extended extended memory; Other memories; Total memory, total memory. BIOS function settings (BIOS enabled and disabled. You can use PAGE UP and PAGE DOWN to switch between them. Cpu kernel speed: the current running speed of CPU; Virus warning: virus warning; Cpu internal cache/external cache (fast access inside and outside CPU); CPU L2 GACHE ECC check (CPU L2 "L2 cache" fast access memory error checking and correcting); Fast power-on self-test This option can adjust the self-test steps of checking the memory capacity three times during the self-test of some computers; CPU update data (CPU update data function); Starting this option from the local area network first can wake up the computer remotely. Start sequence This is a function that we often adjust. Usually the order we use is: A, C, SCSI, CDROM. If you need to boot from CD, you can adjust it to boot from CDROM only. Normal operation, it is best to adjust to boot from disk C, BIOS crash protection; Processor serial number (Pentium 3 processor is automatically detected by the system); Swap floppy drive (swap floppy drive letter); VGA boot from (boot display selection); Start floppy disk seek (whether to automatically detect floppy disk when starting); Boot NUMLOCK status (setting of keyboard area at boot time); Automatic rate setting; Typing speed (characters/second, bytes/second); If the TYPEMATIC Delay Security option is set to SETUP, you will be prompted to enter a password (ordinary user password or super user password, ordinary users have no right to modify BIOS settings) every time you start the screen, and you cannot use the machine without knowing the password; If it is set to SYSTEM, the user will be prompted to enter the super user password only when he wants to enter the BIOS setup. Memory parity: If the memory bank configured on the machine does not have parity function, this item must be set to disabled. At present, most microcomputers (including brand machines) have no parity check. PCI/VGA palette snooping (color correction); Assign IRQ to VGA) IRQ)IRQ the system interrupt address. Operating system selection of DRAM & gt64MB (setting the memory capacity used by OS2) If the OS/2 system is being used and the system memory is greater than 64MB, this item should be enabled, otherwise the memory above 64MB cannot be used, and it is generally disabled. ; . HDD S.M.A.R.T capability This option can be used to automatically detect the working performance of the hard disk. If the hard disk is about to be damaged, the hard disk self-test program will give an alarm. The floppy drive of WIN95 (IRQ6 is assigned to the floppy drive) is not reported. Video BIOS shadow (using VGA BIOS shadow) is used to improve the display speed of the system and is usually turned on. C8000-CB FFFFFF Shadow: This area is mainly used to map the ROM content on expansion cards (network cards, decompression cards, etc.). ) and put them in the host RAM to run, thus improving the speed.
Detailed description of BLOS settings
As a bridge between hardware and operating system, BIOS can set system operation mode and hardware-related parameters. When the system is turned on, the BIOS will first perform a power-on self-test (POST). At this point, press the Del key to enter the BIOS setup main screen. Here we will explain the function and running mode of BIOS. Its function and operation mode are described as follows: standard CMOS setting system basic parameter setting This option is mainly used to set system basic parameters. The user selects the setting item and uses the Page Up and Page Down keys to modify the content. In each option, you can press the key to display the contents available for that option. Date sets the current date. Setting range: month: 1 to 12 (day): 1 to 3 1 year (year): set the current time by 2079 (hour). Setting range: hours: 00 to 23 minutes (minutes): 00 to 59 seconds (seconds): 00 to 59 hard disks (hard disks). This option is used to set all IDE hard disks (master/slave; Secondary master/slave) typeEach option is explained as follows: Auto: allows the system to automatically detect the hard disk type and set it when it is turned on. None: No hard disk is installed. User: Allows users to set their own hard disk related parameters. Including CYLS, HEAD, PRECOMP and LANDZ. These specifications are detailed in the instructions attached to the hard disk drive, such as the number of magnetic heads. [Special Note]: BIOS does not support SCSI hard disk settings. As for the mode, there are three choices: normal mode: it is a traditional standard mode, which supports hard disk capacity up to 528MB. LBA (Logical Block Mode) mode: it is suitable for hard disk capacity exceeding and supports logical block mode: when the hard disk capacity exceeds 528MB and the hard disk or operating system does not support LBA mode, this option can be adopted. DriverA/DriverB(None) This option sets the type of floppy disk drive, and the options are: 360KB, 5.25in 1.2MB, 5.25in720KB, 3. 5in 1.44MB, 3.5in2.88MB, 3.5in none and six other types. If you use Japanese standard mode floppy disk drive (Floppy3Mode), set Floppy3ModeSupport (the default value is Disable). Otherwise, please disable this setting function. Options include riveA, driveB, Both, and Disable. Video (video card type, the default value is EGA/VGA) Sets the video card type, and the options are MONO (monochrome), EGA/VGA (color), CGA40 and CGA80. HaltOn (the default value is AllError) This column sets what type of exception will cause the system to pause booting. The options are: All Errors: If there are any errors, the system will display an error message and pause the boot. NoErrors: No matter what the error is, the system will start as usual. All, Butkeyboard: If there is an error, the system will stop booting, but the keyboard will start as usual. All, ButDisk/Key: If there is an error, the system will stop booting, but the disk drive and keyboard will be turned on as usual. BIOS characteristics SetupBIOS special parameter setting This setting can enhance the performance of your system according to your system and requirements, but if you don't know much about the set function, it is recommended that you use the default value. The operation method of function keys is described in the lower right of the main interface of this setting. The BIOS special parameter setting function is described as follows: VirusWarning virus protection warning (the default value is Disable) This function can prevent the boot sector and partition of the hard disk from being changed, and any attempt to write to this area will cause the system to crash and display a warning message. [Special Note]: When you install a new operating system (such as Win98), please turn off this function first, so as to avoid the smooth installation due to sudden changes. CPUInternalCache(CPU internal cache, default value is Enable) This function is used to enable or disable CPU level 1 cache. In terms of overall speed, enabling L 1 caching is much faster than canceling L 1 caching. Therefore, the default value is enable. ExternalCache (external cache function, default value is Enable) This function is used to enable or disable CPU secondary cache. In terms of overall speed, enabling L2 cache will be much faster than canceling L2 cache. Therefore, the default value is enable. PentiumProCPU has built-in L2 cache. QuickPowerOnSelfTest (default value is Enable) When the computer is turned on, the BIOS will perform a series of POSTs. When this function is enabled, the test of the same project will be simplified and skipped to shorten the startup time. Hddsequencescsi/IDE takes precedence (IDE/SCSI hard disk startup priority, default value is IDE). When both SCSI and IDE hard disks are installed, this option function can be used to select SCSI or IDE hard disk as the startup disk. BootSequence (default value is C, A) This option sets the priority of selecting disk A, disk C and CD-ROM drive to start when the computer is turned on. SwapFloppyDrive (the default value is Disable) When this function is enabled, disks A and B are swapped. That is, the original A disk was designated as B disk, and B disk was designated as A disk. In this way, you don't need to open the chassis to exchange cables. BootUpFloppySeek (the default value is Disable) When this function is enabled, the BIOS POST program will detect whether a floppy disk exists when the computer is turned on. Otherwise, skip this detection operation. FloppyDiskAccessControl (R/W by default) This function is mainly used to control the storage of floppy disks. 5 ∪ ∪ eadOnly ",data can only be read from floppy disks, and system data cannot be copied to floppy disks. When read/write is selected, the floppy disk can read data normally. BootUpNumLockStatus (on by default) On: When the computer is turned on, the number keys are set to digital status Off: When the computer is turned on, the number keys are set to direction status IdehddblockModeSectors (HDDMAX by default). Most new IDE hard disks support the function of transferring multiple sectors at a time. Enabling this feature can speed up hard disk access. Options include HDDMAX, Disabled, 2, 4, 8, 16 and 32. TypematicRateSetting (the default value is Disable) This option is used to decide whether to enable the keyboard speed setting function. If enabled, the settings of TypematicRate and TypematicRelay will take effect. Typematic (character/second, keyboard repetition rate, default value is 6) This option sets the number of characters that appear per second when you hold down the key. Options are: 6, 8, 10, 12, 15, 20, 24, 30 (words per second). Typematicdelay (input delay time, default value is 250ms) When the key is not pressed, the keyboard will repeatedly input characters at a certain rate after the set delay time is exceeded. Options are 250ms, 500ms, 750ms,1000ms. SecurityOption (default value is System) This option requires the user to enter a password, and there are two options: System: You must enter the correct password every time you start the machine, otherwise you cannot start the machine. Setup: Only when entering the BIOS setup will the system ask for the correct password. When PS/2MouseFunctionControl(PS/2 mouse function control, default value is Auto) is set to Auto, the system will detect whether the PS/2 mouse exists. If it exists, IRQ 12 is reserved for PS/2Mouse. If it is set to disabled, IRQ 12 is reserved for the adapter, and the PS/2 mouse has no function at this time. PCI/VGAPaletteSnoop (the default value is Disable) If non-standard VGA cards (such as image accelerator cards and MPEG cards) are used, sometimes colors cannot be displayed normally. Setting it to "Enab le" will solve this problem. In addition, the default value is recommended. OS/2 onboardmemory & gt； 64M (the default value is disabled) If the operating system uses OS/2 and the installed main memory capacity exceeds 64MB, it is set to be enabled; Otherwise, it will be set to the default value of disable. When this function is enabled, the BIOS of VGA will be copied to the main memory to speed up the execution. If this function is disabled, the display speed will become very slow. C8000-CBFFFtoDC000-DFFFF (the default value is Disable) If other adapter cards are used, when this function is selected, the system will use the Shadow technology to speed up the operation of the RO M on the adapter card. However, this will take up space in main memory. Chipset feature setting Chipset parameter setting: This option mainly adjusts the performance of hardware files through chipset parameter setting. If you are not familiar with these settings, I suggest you use the default values. Automatic configuration (default value is 60nsDRAM) You can select the 60 MDR Amor 70 nsram option according to the memory you use, and the BIOS will automatically adjust options 2 to 9 according to your settings. If "Disabled" is selected, options 2 to 9 can be adjusted by themselves. SDRAMCAS#Latency (the default value is 3T) If a faster SDRAM module is used, it can be set to 2T for faster access speed. Otherwise, set it to the default value of 3T, or consult the dealer for DIMM specifications. Sdram speculates on veRead (default: DISAble) PassiveRelease (default: Enable) RelayTransaction (default: disable) 16-bit/orecoOvertime (16-bit I/O recovery time, Default value: 1BUSCLK) is defined as 16-bit isa card I/O. 8- bit I /ORecoveryTime(8-bit I/O recovery time, default value is 1BUSCLK) Disabled: this function is cancelled. MemoryHoleatAddress (default value is None) Some ISA cards need to use 14- 16MB or 15- 16MB memory address space. If you select 14MB- 16MB or 15mb-65438, you can cancel this function by selecting none. Onboarddfdcswapa:BA and b disk interchange; The default value is NoSwap) When this feature is enabled, the A and B disks are interchanged. That is, the original A disk was designated as B disk, and B disk was designated as A disk. The default value of OnboardSerialPort 1 is 3F8H/IRQ4) Set the address of serial port 1 on the motherboard and the default value of IRQ OnboardSerialPort2 is 2F8H/IRQ3) Set the address of serial port 2 on the motherboard and the default value of IRQ OnboardParallelPort is 378H/IRQ7) Set the address and IRQ of parallel port on the motherboard. ParallelPortMode (default value is ECP+EPP) sets the operation mode of parallel port, with the following options: Normal: general speed unidirectional execution. Maximum speed bidirectional execution. ECP: Ultra-high speed double self-execution. ECP+EPP:ECP and EPP are used together. When ECPDMASelect(ECPDMA channel selection, default value is 3) works in ECP mode, there are three settings for DMA channel selection: 1, 3 and disabled. UART2UseInfrared (the default value is Disable) This function is used to support the infrared (IR) transmission function. Enable: Set the second serial UART to support infrared transmission function. Disabled: Set the second serial port UART to support COM2. OnboardPCIIDEEnable (motherboard IDE channel, default value is Both) is used to enable the built-in IDE channel. Options are: Primary Deachannel Secondary Channel Both Disable. When the default value of IDE0Master/SlaveMode, IDE 1Master/SlaveMode is Auto, the system will automatically detect the timing modes of the four IDE devices to ensure the best speed. You can also set the timing mode to (0, 1, 2, 3, 4). Power management settings power management settings VideoOFFOption (close the screen power saving settings, the default value is Susp, Stby-& gt；; Off) This option is used to set the time when "Screen Off" is enabled in the screen power saving management mode. Optional items are described as follows: Susp, Stby-& gt；; Turn off: Turn off the screen only in standby or pause power saving mode. Hang->; Off: Turn off the screen display only in suspend mode. Alwayson: Don't turn off the screen display in any mode. All modes-> Off: Turn off the screen display in any power saving mode. VideoOFFMethod (screen closing mode, default value is V/HSYNC+Blank) is used to select the screen closing mode. But if you can't close the screen smoothly, set it to "blank". If the video card supports DPMS function, set it to "DPMS". PWRButton & lt4 seconds (hold down the power button for less than 4 seconds, the default value is SoftOff) This function sets the operation mode of the system when the power button is held down for less than 4 seconds. Soft shutdown: perform ATX power software shutdown. Suspend: The system enters suspend mode. NOFunction: cancels any function related to ATX switch. [Note]: Once PWR is pressed for more than 4 seconds, the system will shut down no matter how it is set. PWRUpOnModemAct (turned on when modem is active, enabled by default) acwrlossrestart (disabled by default) -pmtimers-HDD power off: When the system does not access the hard disk within the selected time, it will enter the power saving mode. The power saving modes are snooze mode, standby mode and pause mode in the order of power consumption. If the hard disk does not act within the selected time of each mode, it will enter the next more power-saving mode in turn. The monitoring device built into the FanMonitor(XXXXRPM) motherboard can detect the fan speed (RPM). If no fan supporting this feature is installed, select Ignore to avoid generating an error message. ThermalMonitor(xxxC/xxxF) motherboard has built-in monitoring equipment, which can detect the temperature of CPU and motherboard. If you choose to ignore, no error message will be displayed when the temperature of CPU and motherboard is abnormal. VoltageMonitor(xx.xV) motherboard built-in monitoring equipment can detect the voltage value of the system. If you select Ignore, no error message will be displayed when the system voltage is abnormal. PNP/PCI Installation Plug and Play and PCI Design PNPOSINSTALLED (whether to install PNP operating system, the default value is No) When using an operating system with PNP function (such as WINDOWS98), you can choose YES. Slot IRQ (interrupt value of PCI slot, default value is AUTO) is used to set the IRQ value of each PCI slot. The projects are NA, 9, 10,12, 13,14,65438+. PCILATENCYTIMER (default value is 32PCICLOCK) Using "32PCICLOCK" will make the PCI speed of the motherboard the fastest. IRQXXUSEDBYISA (the default value is NO/ICU) is used to reserve a specific IRQ for non-PNP ISA cards.
