【 Weak current College 】 BOIS password settings and unlock method




First, an overview

The password on your computer, many people thought it was a computer whiz, but it is not, set password and not the master of the patent. Let us first look at the computer what are common password:

1, the screen saver password;
2. software and file permissions password;
3. network connection permissions password;
4, BIOS password;

The above password to a few "screen saver password settings and unlock the" most easily; files and network password cracking most difficult; the BIOS password on most computer users.

BIOS basic input/output system. BIOS settings commonly known as "CMOS settings", that is, the curing in ROM on the motherboard's BIOS utility in the amendment of the various parameters of your computer in order to affect your computer's capabilities, and use rights. BIOS password also called a "CMOS password", the main purpose of the password settings are:

1. prevent others feel free to modify the BIOS settings to ensure the normal operation of your computer.
2. limit the use of computers to protect computer resources.

2. password setting method

BIOS version although there are more, but basically the same as the password set method. Now Award4.51PG version (below), for example. In the computer startup process, when the screen below appears Tip: hold down the "PressDELtoenterSETUP" Del keys to enter.

By: when powering on the bottom of the screen, when prompted to "press Del PressDELtoenterSETUP" and the password set for one of the project are:

"BIOSFEATURESSETUP" (the BIOS features Setup)
"SUPERVISORPASSWORD" (Administrator password)
"USERPASSWORD" (user password)

Select an item, carriage return, to the project settings. Select the administrator or user password after carriage return, asks for a password, enter after carriage return, prompting the validate password, enter the same password again, carriage returns can be. It should be noted that,in any setting, you must save on exit in order to let the settings to take effect. (Save: after selecting the "set SAVE & EXITSETUP" or press F10, prompted "SAVEtoCMOSandEXIT (Y/N)? then press" y ", save the completed. )

Specific settings in the following ways:

Method 1: set up a separate setting "SUPERVISORPASSWORD" or "USERPASSWORD" any of them, and then open the "BIOSFEATURESSETUP" be "SecurityOption" set to "Setup", save and exit. Then, press the del key when powered on the BIOS Setup screen you will be asked to enter your password, enter the operating system does not require you to enter a password.

Method 2: set up a separate setting "SUPERVISORPASSWORD" or "USERPASSWORD" any of them, and then open the "BIOSFEATURESSETUP" be "SecurityOption" set to "System", save and exit. In this way, not only to enter the BIOS settings require a password, and enter the operating system will require you to enter a password.

Set method 3: set "SUPERVISORPASSWORD" and the "USERPASSWORD", and the use of two different passwords. Then open the "BIOSFEATURESSETUP" be "SecurityOption" set to "System" and exit. So, enter BIOS settings and the operating system requires a password, and enter any password to enter the BIOS Setup and operating system. But the "administrator password" and "user password" differentiated: the "administrator password" to enter the BIOS program you can make any settings, including modifying user passwords. But to the "user password" to enter, modify or remove the "user password", you cannot make any settings, you cannot modify the administrator password. Thus, in this setting, the "user password" access "below" the administrator password.

3. password utility

Password though a maximum of only two, but if it can reasonably be applied then subtly benefits.

1. public computers: If the school computer lab, Office, etc. Generally use the "method 1" is set, the password does not open, allowing others to access the operating system to use the computer, but don't let people enter the BIOS screen, feel free to modify the BIOS settings to protect your computer properly.

2, personal computer, if you do not want to let the other person uses: generally use the "set" method 2, password not openly, in which others can't enter the BIOS Setup, you cannot enter the operating system.

3, personal computer, but allows you to specify several personal use: generally use the "set method 3"?? Set two password respectively, and the "user password" inform the specified use, their own reservations "administrator password". If would like to cancel the others use qualifications, you can enter the BIOS is the original "user password" to cancel or modify. While others are unable to modify the "administrator password", this, the initiative still in their own hands.

IV.Password removal and crack

Password is a protective effect, but if your forget your password it will lead to trouble. Therefore, in addition to setting a password, but also to learn how to get rid of and crack the password.

1, password removal:

Password of "removal" means the already know the password from the password.

By: enter BIOS Setup screen, select the set password "SUPERVISORPASSWORD" or "USERPASSWORD", carriage return after the "EnterPassword", do not enter a password, press ENTER. When prompted:

"PASSWORDDISABLED!!! (remove password!!!)
Pressanykeytocontinue…… (Press any key to continue ... )”

Press any key to exit after saving the password will be removed.

2, password-cracking:

Password of "crack" is the password to enter the BIOS settings or the operating system determine passwords. Methods are as follows:

(1) program cracking method:

This method applies to access to the operating system, but you can't enter the BIOS settings (password required). By: will the computer switches to DOS, prompt "C:WINDOWS >" followed by the following explains the procedures:

debug
-O7010
-O71ff
-q

Use the exit command to exit the DOS, password is compromised. Because the BIOS version varies, sometimes this program cannot solve, you can use another similar program to crack:

debug
-O7120
-O7021
-q

Use the exit command to exit the DOS, reboot and press Del to enter BIOS, then you will find that there is no password for retaining your road!

(2) discharge method:

When the "BIOS settings," and "operating system" are unable to enter, you will not be able to switch to DOS mode for an application to determine passwords. At this point, only the use of discharge method. Discharge method has two kinds: one is the "jumper discharge method"?? Open the host box, found on board a and the jumper COMS (refer to your motherboard documentation), this jumper is usually in 1-2 pins, as long as it is in 2-3 pins, and then put back to 1-2 pins to clear the password. The other is "COMS battery discharge method"?? Open the host box, found on board a fastener battery, called the CMOS battery (for BIOS of separate power supply, ensure that no BIOS settings for your computer's power off and lost), remove the battery, wait for the COMS 5 minutes back into the password to unlock the battery. But at this point the BIOS password regardless of how to set up, use universal password to enter the BIOS settings and operating system. Of course, its own set of password can also be used. Other settings in the BIOS will be restored to its original state, to optimize computer performance or to resolve a hardware conflict need to reset it.

(3) universal password:

Production earlier some motherboards, the manufacturers have universal password (refer to your motherboard documentation), such as: to six "*" as a universal password. This motherboard, BIOS password regardless of how to set up, use universal password to enter the BIOS settings and operating system. Of course, its own setof password can also be used.
