"CMOS password" is commonly known as the power-on password, mainly to prevent others from using a barrier set by their own computer. However, in many cases, I will also shield myself. Some people can't remember the password, and often forget the password. This will cause a lot of trouble for themselves. In fact, there are many ways to crack the CMOS boot password. The main ones are as follows. Several: First, change the hardware configuration When you lose the CMOS password, you can try to change the hardware of the machine and then restart, because if the system finds that the new hardware configuration is different from the original hardware configuration, it may be allowed You go directly to the CMOS reset without a password. The method of changing the hardware configuration is very simple: for example, unplug a memory module or install a different type of CPU (of course, support the motherboard), replace a hard disk, and so on. Second, establish your own password crack file A. When the system self-test is completed, press F8 when you are ready to boot Windows, select "Safe mode command prompt only" (safe command mode) and enter COPY CON YK at the DOS prompt. COM, enter the editing environment and enter: ALT+179, ALT+55, ALT++136, ALT+216, ALT+230, ALT+112, ALT+176, ALT+32, ALT+230, ALT+ 113, ALT+254, ALT+195, ALT+128, ALT+251, ALT+64, ALT+117, ALT+241, ALT+195, and then save by F6. Note that when entering the above data, press the ALT key first, then press the number key in the numeric keypad (pressing the row of numeric keys on the keyboard is not working), after losing a number, release the ALT key, and then Press the ALT key to enter the next digit …… During the input process, a random character will appear on the screen every time you release the ALT key. We don't care about it. After saving and exiting, we directly run the YK.COM file. There should be no prompt message on the screen. Then restart the computer to clear the password in CMOS. Of course, other settings in CMOS will be cleared at the same time. This requires us. Reset it again. B. After selecting the security command mode at startup, enter COPY CON YK.COM, and then enter in the editing environment: ALT+176, ALT+17, ALT+230, p, ALT+176, ALT+20, ALT+230 , q, ALT+205, space, press F6 to save and run this file, restart the computer. Third, the DEBUG method at the DOS prompt, after running DEBUG, enter: — o70 18 & mdash; o71 18 & mdash; q or & mdash; o70 21 & mdash; o71 21 & mdash; q exit to the DOS prompt and restart the computer will completely clear the CMOS password . Please note that 70 and 71 are the two ports of CMOS. We can write some error data (such as 20, 16, 17, etc.) to them, which will destroy all the settings in CMOS. Friends who have time may wish to use a few more. Try the data. Fourth, the universal password If someone sets the security option in COMS as the system, then you must enter the correct password every time you turn on the phone, otherwise don't say enter Windows, even DOS can not enter, so we can only rely on the universal password To solve the problem. AMI BIOS: AMI; SysgAWARD BIOS: award; Syxz; h996; wantgirl; eBBB; dirrid. The above universal password cracks CMOS passwords on 386, 486, Pentium motherboards, and the motherboards with PII level or above are not so fascinating. The new passwords for new motherboards with PII and above can be cracked, and almost never heard of them. However, the younger brother found a password ——abaubjao, has successfully cracked the CMOS password on more than ten motherboards such as 6ATA4 (PIII), Weige MVP4 (K6— 2), Mercedes-Benz 160A, 160A+ (PIII), etc. Exclusive, here is dedicated to everyone. 5. Using the tool software on the Internet, you will find that the software that can crack the CMOS password is everywhere. I think the best software is Biospwds. It is a small software made by the Germans. It only needs to be lightly used. Get passwords & rdquo; button, your CMOS password will be displayed on the screen, in addition you can also see the BIOS version, time and other information. Sixth, discharge If you are too bad luck, you can't crack the CMOS password with the above methods, then only this way can go. Open the motherboard manual, find the jumper that clears the CMOS settings, change the short-circuit method as described in the manual, and clear the CMOS. What, your motherboard is too old, without this jumper? Then take the button battery on the motherboard. How can I not open the machine after discharging? Put the battery back.
