How To Crack a BIOS Password
Desktop :-
. Power off the computer and make
sure that it is unplugged.
. Open up your computer case. You need physical
access to the motherboard to complete this procedure.
. Find a circular, (mostly) silver
metallic object on the motherboard. This is the CMOS battery.
. CAREFULLY remove the CMOS
battery, avoid touching it with your fingers, and leave it out for about 700
seconds. This will flush the CMOS memory which stores the BIOS password and all
other configuration. (See Warnings)
. Set the battery back into place and power on the computer.
. The computer should then warn you that the CMOS configuration could not be
found. You can either reconfigure it yourself or restore defaults. Restoring
the default configuration should be fine.
. You will notice that the BIOS password has been cleared and you can boot
without it. You may reset the BIOS password to something else by going into the
BIOS configuration and setting a new User Password (The Supervisor Password
controls access to the BIOS, NOT the computer!)
Old Laptop:-
. Remember that laptops can be trickier, especially if it’s a newer model.
If it has a security chip on the motherboard forget about it. You either have
to physically remove the chip or contact the mfg for the “master” password. If
you can boot up off of a cd or floppy try any of these methods: Create a Win98SE bootable media “or
anything that lets you boot into MS-DOS” and boot off of it.
. When the A:\> prompt appears
type debug and press enter.
. You will then only see a “-“.
. Type o 70 2E “include the
spaces” and press Enter.
. Type o 71 ff “include the
spaces” and press Enter.
. Type q and press Enter.
. Here are a list of common mfg
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 gvs
BIOS/CMOS Password Recovery Tool is the most effective.: BIOS/CMOS Password
Recovery Tool is a program that works instantly to remove any lost or forgotten
BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get
access to forgotten BIOS/CMOS passwords in just seconds

TIPS:-
. Depending on the manufacturer of your motherboard, you may be able to use
what it is called a “backdoor password” to bypass the password problem. Try
looking at the external links for possible passwords.
. Remember that passwords are Case Sensitive. The last two passwords in the
AWARD BIOS list are in Russian.
. Sometimes the bios reset jumper has a “handle” and is colored a bright
color to make it easy to locate. Also, look in your case near the bottom. If it
is a manufactured computer then it probably came with a little sticker with the
jumpers and the location of the reset jumper.
. If you’re really stuck, the PC manufacturer can often give out a “reset
password” if you can prove you are the owner. This works with Dell but they
usually charge.
WARNINGS:-
In rare cases, the battery may be soldered into the motherboard and very
difficult to remove. If this is true, you may need to find a jumper near the
battery that achieves the same result. If you don’t know which jumper it is,
you CAN test them all. Unplug (really unplug, not just power off) the computer,
and start a methodical change in all the jumpers positions, change one, count
to ten, change it back, move on the next. After completing the lot of them (on
older motherboards this could take a while) plug the PS back in, and boot up.
You may risk damaging your computer with this procedure if you are not careful.
Some notebooks such as IBM’s ThinkPad render useless when the BIOS password
is being tried to reset.
Don’t just start pulling jumpers on the motherboard. Make sure you know
where it was and in what position in case anything goes wrong put it back.
If you turn your computer on and it makes strange noises / beeps, you
should contact the vendor, manufacture, or a tech guy to fix it.
