How to Bypass BIOS Passwords
http://www.labmice.net/articles/BIOS_hack.htm

There is lot of info on at the above link these are just the basic things to try

Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch  CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.  
Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches,  turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.
--------------------------------------------------------------------------------

Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.  
Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all.  IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system.
--------------------------------------------------------------------------------

Overloading the KeyBoard Buffer

On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key over 100 times in rapid succession.

Standard BIOS backdoor passwords

The first, less invasive, attempt to bypass a BIOS password is to try on of these standard manufacturer's backdoor passwords:

AWARD BIOS
AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, 01322222, 589589, 589721, 595595, 598598, HLT, SER, SKY_FOX, aLLy, aLLY, Condo, CONCAT, TTPTHA, aPAf, HLT, KDD, ZBAAACA, ZAAADA, ZJAAADC, djonet, %øåñòü ïpîáåëîâ%, %äåâÿòü ïpîáåëîâ%

AMI BIOS
AMI, A.M.I., AMI SW, AMI_SW, BIOS, PASSWORD, HEWITT RAND, Oder

Other passwords you may try (for AMI/AWARD or other BIOSes)
LKWPETER, lkwpeter, BIOSTAR, biostar, BIOSSTAR, biosstar, ALFAROME, Syxz, Wodj

Note that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards (such as Italian and German ones), so -- for example -- you should type AWARD?SW when using those keyboards. Also remember that passwords are Case Sensitive. The last two passwords in the AWARD BIOS list are in Russian.


Flashing BIOS via software

If you have access to the computer when it's turned on, you could try one of those programs that remove the password from the BIOS, by invalidating its memory.
However, it might happen you don't have one of those programs when you have access to the computer, so you'd better learn how to do manually what they do. You can reset the BIOS to its default values using the MS-DOS tool DEBUG (type DEBUG at the command prompt. You'd better do it in pure MS-DOS mode, not from a MS-DOS shell window in Windows). Once you are in the debug environment enter the following commands:

AMI/AWARD BIOS

O 70 17
O 71 17
Q

PHOENIX BIOS
O 70 FF
O 71 17
Q

GENERIC
Invalidates CMOS RAM.
Should work on all AT motherboards
(XT motherboards don't have CMOS)
O 70 2E
O 71 FF
Q

Note that the first letter is a "O" not the number "0". The numbers which follow are two bytes in hex format.

You could try various backdoor default passwords.
(THESE ARE CASE SENSITIVE).

AWARD  :

 djonet
 AWARD_SW
 AWARD?SW
 lkwpeter
 aLLY
 589589
 j262
 

Other Bios

 biostar
 biosstar
 LKWPETER
 BIOSTAR
 j262
 j256
 Syxz
 Wodj
 

Ami

Oder
A.M.I.
AMI_SW
AMI?SW

Or crack it with debug

Enter debug at the command prompt (You must have debug.exe on your system.)
After this enter the debug commands as follows.

O70,1E
O71,FF
O70,1F
O71,FF
