Many people use BIOS password to lock up their computers, making them completely unusable without entering the correct password. This password has to be entered before loading the operating systems, normally on a DOS screen shortly after the computer started. BIOS password is usually stored together with other BIOS settings such as the time, date and size of the hard disk. These pieces of data are usually stored in a flash chip on the motherboard.
To reset or remove BIOS password, look for a jumper which usually can be found near the processor or BIOS battery on the motherboard. After locating the jumper (usually with a label - PSWD beside it), move the jumper from connected pins 1+2 to pins 2+3 for a few seconds or so, then move back to pins 1+2. This will reset the entire BIOS settings. The next time you boot your computer, the BIOS will show you the default factory settings and from there you can optionally set a new password.
Here are the Commands :
Type debug
Type o 70 2e
Type o 71 ff
Type q
By Putting this commands your Machine's Bios has been reset. Now restart your computer and everything should run just fine.
Another alternative way to completely reset your bios setting is to reinsert the CMOS battery which can be found on the motherboard. The CMOS battery provides power supply to the motherboard in order to hold the BIOS settings data.
