Onboard BIOS language
There are a variety of phrases in English that appear after a problem occurs during bootup, and these phrases contain very important information. Read these messages can solve some small problems by yourself, but these English difficult to defeat part of the friends, the following is the explanation of some common BIOS phrases, you can refer to it.
(1).CMOS battery failed
Chinese: CMOS battery failed.
Explanation: This means the CMOS battery is almost dead, just replace it with a new one.
(2).CMOS check sum error-Defaults loaded
Chinese: CMOS found an error while executing all the checks to load the system presets.
Interpretation: Generally speaking, this sentence is to say that the battery is almost dead, you can first change the battery to try, if the problem is still not solved, then it shows that there may be a problem with the CMOS RAM, if not more than a year to the dealer for a motherboard, after one year, let the dealer to send it back to the manufacturer to repair it!
(3).Press ESC to skip memory test
Chinese: Memory checking is in progress, you can press ESC to skip.
Explanation: This is because there is no setting in CMOS to skip the second, third, or fourth test of memory, and four memory tests will be performed when you turn on the computer, of course you can press ESC to end the memory check, but it's too much trouble every time you have to do this, you can enter the COMS setup and then select BIOS FEATURS SETUP, and set one of the Quick Power On Self Test to Enabled, store it and reboot.
(4).Keyboard error or no keyboard present
Chinese: Keyboard error or no keyboard present.
Explanation: Check if the keyboard cable is loose or damaged.
(5).Hard disk install failure
Chinese: Hard disk install failure.
Explanation: This is because the power or data cable of the hard disk may not be connected properly or the hard disk jumper is not set properly. You can check if the hard disk's connecting cables are plugged in properly, and see if the jumper settings of two hard disks on the same data cable are the same, if they are the same, just set the jumper settings of the two hard disks differently (one is set to Master, the other is set to Slave).
(6).Secondary slave hard fail
Chinese: Detection of slave disk failed
Explanation: It may be that the CMOS is not set properly, for example, there is no slave disk, but in the CMOS is set to have a slave disk, then the error occurs, then you can go to the COMS settings to select the IDE HDD AUTO DETECTION for hard disk auto-detection. It is also possible that the power and data cables of the hard disk may not be connected properly or the hard disk jumper is not set properly, the solution refers to Article 5.
(7).Floppy Disk(s) fail or Floppy Disk(s) fail(80) or Floppy Disk(s) fail(40)
Chinese: Cannot drive the floppy disk drive.
Explanation: The system prompted to find the floppy drive, look at the floppy drive power cord and data cable is not loose or connected to the wrong, or put the floppy drive to another machine to try, if these are not working, then you have to buy another one, the good thing is that the floppy drive is not expensive.
(8).Hard disk(s) diagnosis fail
Chinese: An error occurred while performing hard disk diagnosis.
Explanation: This problem generally means that the hard disk itself is faulty, you can put the hard disk on another machine to try, if the problem is still not solved, you can only go to the repair.
(9).Memory test fail
Chinese: Memory test fail.
Explanation: Re-plug the memory stick to see if it can be solved, this problem is generally because the memory stick is not compatible with each other, go to change a bar!
(10).Override enable-Defaults loaded
Chinese: The current CMOS setting cannot boot the system, load the preset value in BIOS to boot the system.
Explanation: Generally there is an error in the COMS settings, just go to COMS setup and select LOAD SETUP DEFAULTS to load the original system settings and then reboot.
(11).Press TAB to show POST screen
Chinese: Press TAB to switch the screen display.
Explanation: Some OEMs will replace the BIOS preset POST screen with their own designed display, we can press TAB to switch between the BIOS preset POST screen and the manufacturer's customized screen.
(12).Resuming from disk, Press TAB to show POST screen
Chinese: Resuming from hard disk, Press TAB to show POST screen).
Explanation: This is because some motherboard's BIOS provide Suspend to disk function, if we use Suspend to disk to shutdown the computer, then we will show this prompt message when we turn on the computer next time.
(13).Hareware Monitor found an error, enter POWER MANAGEMENT SETUP for details, Press F1 to continue, DEL to enter SETUP
Chinese: Monitor found an error, enter POWER MANAGEMENT SETUP for details, Press F1 to continue, DEL to enter SETUP.
Explanation: Some motherboards have hardware monitoring functions, which can be set to monitor the temperature of the motherboard and CPU, monitor the voltage output of the voltage regulator, and monitor the speed of each fan, when the above monitoring function is found to have abnormalities when booting up the computer, then the above paragraph will appear, then you can enter the COMS setup to select POWER MANAGEMENT SETUP, in the right side of the POWER MANAGEMENT SETUP, press DEL to enter the COMS setup. SETUP, on the right side of the **Fan Monitor**, **Thermal Monitor** and **Voltage Monitor** to see what part of the anomaly, and then to solve.
Overview
On the computer password, many people think that it is a computer expert, in fact, not, set the password is not the patent of the expert. And let's look at the computer what are common passwords:
1, screen saver password;
2, software and file access password;
3, network access password;
4, BIOS access password;
The above passwords should be counted as "screen saver password" set and release the most.
BIOS The Basic Input/Output System (BIOS). The BIOS password, also known as the "CMOS password", is set to prevent others from modifying the BIOS settings at will to ensure the normal operation of the computer.
2, to restrict others from using the computer to protect the resources in the computer.
II. Password setting method
The BIOS version has more than one, but the password setting method is basically the same. Now take Award 4.51 PG version (the following figure) as an example. During the startup process, when a prompt appears at the bottom of the screen: "Press DEL to enter SETUP", press and hold the Del key to enter.
The method is: boot, when the bottom of the screen appears to prompt "Press DEL to enter SETUP" when holding down the Del which is related to the password settings of the project are:
"BIOS FEATURES SETUP
"BIOS FEATURES SETUP"
"SUPERVISOR PASSWORD"
"USER PASSWORD"
"User password"
The password is the password for the user. Password)
Select one of the items and enter to set the item. After selecting the administrator or user password item, enter, asked to enter the password, enter and then enter, prompted to verify the password, enter the same password again, enter can be. It should be noted that, after any setting, you must save it when you exit in order to let the setting take effect. (Saving method is: after the setup is completed, select "SAVE & EXIT SETUP " or press the F10 key, there is a prompt "SAVE to CMOS and EXIT(Y/N)? (At this time, press the "Y button" to save the completion.)
Specific settings are divided into the following methods:
Setting method 1: individually set the "SUPERVISOR PASSWORD" or "USER PASSWORD" any of them, and then open the "BIOS FEATURES" dialog box. "BIOS FEATURES SETUP" will be one of the "Security Option" set to "Setup", save and exit. In this way, when you press the Del key to enter the BIOS setup screen, you will be asked to enter your password, but not when you enter the operating system.
Setup method 2: Setup either "SUPERVISOR PASSWORD" or "USER PASSWORD" individually, and then open "BIOS FEATURES SETUP" to set the "Security Option" to "System", save and exit. In this way, not only will you be required to enter your password when accessing BIOS settings, but you will also be required to enter your password when accessing the operating system.
Setup method 3: Setup "SUPERVISOR PASSWORD" and "USER PASSWORD" respectively, and use two different passwords. Then open the "BIOS FEATURES SETUP" to set the "Security Option" to "System", exit and save. Exit and save. In this way, the password is required to enter both BIOS setup and operating system, and you can enter either one of the passwords to enter BIOS setup and operating system. However, there is a difference between the "Administrator Password" and the "User Password": when entering the BIOS program with the "Administrator Password", you can make any settings, including changing the user password. However, when you enter the BIOS program with the "user password", you can't make any other settings except for modifying or removing the "user password", and you can't change the administrator password. In this case, the "user password" is lower than the "administrator password".
Three, the password is useful
While there are at most two passwords, if you can reasonably and skillfully use them, they will be of great benefit.
1, public **** occasion of the computer: such as school rooms, offices, etc.. General use of the "setup method 1", the password is not open, this allows others to enter the operating system to use the computer, but does not allow others to enter the BIOS screen to modify the BIOS settings to protect the normal operation of the computer.
2, personal computer, if you do not want to let anyone else use: generally use the "setup method 2", the password is not public, this time others can not enter the BIOS settings, and can not enter the operating system.
3, personal computer, but allows a specified number of people to use: generally use the "setup method 3"? The two passwords are set up separately, and the "user password" is communicated to the designated user, while the "administrator password" is retained by the user himself. If you want to disqualify others, you can enter BIOS to cancel or modify the original "user password". The other people can't change the "administrator password", so the initiative is still in their hands.
Four, the removal of the password and crack
Password certainly has a protective effect, but if you forget the password will bring trouble. Therefore, in addition to setting up a password, you should learn to remove and crack the password.
1, the removal of the password:
Password "removal" refers to the case of already know the password to remove the password.
The method is: enter the BIOS setup screen, select the "SUPERVISOR PASSWORD" or "USER PASSWORD" that has been set as the password, and then enter, the "Enter Password" will appear. "Enter Password", do not enter the password, directly press the Enter key. At this time, the screen appears prompt:
" PASSWORD DISABLED ! (Remove Password!!!)
Press any key to continue ......"
Press any key and exit save, the password is removed.
2, password cracking:
Password "cracking" refers to the password in the case of forgetting the password, can not enter the BIOS setup or can not enter the operating system to crack the password. Methods are as follows:
(1) program to crack the method:
This method applies to the operating system can be accessed, but can not enter the BIOS setup (requires the entry of the password). The specific method is: the computer will be switched to DOS state, at the prompt "C: WINDOWS>" enter the following crack program:
debug
- O 70 10
- O 71 ff
- q
and then use the exit command to exit DOS. exit command to exit DOS and the password is cracked. If this program doesn't work because of the different BIOS versions, you can use another program that does:
debug
- O 71 20
- O 70 21
- q
Exit DOS with the exit command, reboot and hold down the Del key to enter the BIOS, and you'll see that the password is no longer blocked. There are no more passwords in your way!
(2) discharge method:
When the "BIOS setup" and "operating system" can not be accessed, it can not be switched to the DOS way to use the program to crack the password. At this point, only the discharge method. There are two kinds of discharge method: one is the "jumper discharge method"? Disassemble the main chassis, on the motherboard to find a jumper related to COMS (refer to the motherboard manual), this jumper is usually inserted in the 1-2 pin, as long as it is inserted in the 2-3 pin, and then put it back to the 1-2 pin to clear the password. Another is the "COMS battery discharge method"? Disassemble the main chassis, the motherboard to find a button battery, called CMOS battery (for BIOS separate power supply, to ensure that the BIOS settings are not lost due to the computer's power outage), take out the COMS battery, wait 5 minutes and then put back the battery, the password can be lifted. However, at this time, no matter how the BIOS password is set, the universal password can be used to enter the BIOS setup and operating system. Of course, the password set by yourself can also be used. All other BIOS settings will be restored to their original state and will need to be reset to optimize computer performance or resolve hardware conflicts.
(3) Universal Password:
Produced earlier, some motherboards, manufacturers have a universal password (refer to the motherboard manual), such as: to six "*" as the universal password. This motherboard, the BIOS password regardless of how to set up, with the universal password can enter the BIOS settings and operating system.
