How to crack or Reset BIOS Password? ~Cracking Tutorials

The BIOS software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). The primary function of the BIOS is to set up the hardware and load and start a boot loader. When the PC starts up, the first job for the BIOS is to initialize and identify system devices such as the video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware. The BIOS then locates software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC. This process is known as booting, or booting up, which is short for bootstrapping.

Bios password is usually used to protect the user's BIOS settings on the computer. If you want to reset the password on the BIOS does not need to bother to connect bateray CMOSnya, with a little trick on the Dos you can reset the BIOS password on it in 2 ways:

1. Clear CMOS
This way I consider the most ancient and most easy to break down the password on the BIOS. The steps are easy, first open the casing cover computer CPU. Then find the bios battery that looks something like the battery just a little more big clock. After the meet and consider the area around the battery there is usually a jumper with 3 pins, 2 pins and 1 pin not connected.

Suppose the three pins with the code 1 - 2 - 3. Connector that connects the initial position usually is 2-3. To reset the bios do I move the position of the plug that connects pins 2-3 to position 1-2 for about 5 seconds. Then plug it back into the starting position (2-3). Try restarting the computer back on, secured the bios password is gone.

If the above looks complicated, is easy to clear cmos by unplugging the BIOS battery and then put it back. But with the consequences of removing the label is the warranty on the battery BIOS.

2. Through DOS
