If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk. Cmos password recovery tools 3.1 RemPass KILLCMOS 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 manufacturer's 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 BIOS passwords can be a liability if a user forgets his password. Here are a few tips and tricks that can help to bypass or reset the BIOS password on most systems. Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include: Using a manufacturers backdoor password to access the BIOS Use password cracking software Reset the CMOS using the jumpers or solder beads. Removing the CMOS battery for at least 10 minutes Overloading the keyboard buffer Using a professional service Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive. Backdoor passwords Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.

Hi,Here's some info about the flash recovery routines of the 2 most comomon BIOS brands: AMI and Award. You may need this guide if you've just messed up your BIOS but it's still kind of beeping, or giving other signs of life (in other words: if the Boot Block part of the BIOS is still working).AMIBIOS (American Megatrends, Inc.)1. Copy a known working BIOS image for your board to a floppy and rename it to AMIBOOT.ROM.2. Insert the floppy in your system's floppydrive. 3. Power on the system while holding CTRL+Home keys. Release the keys when you hear a beep and/or see the floppy light coming on.4 . Just wait until you hear 4 beeps. When 4 beeps are heard the reprogramming of the System Block BIOS went succesfull, so then you may restart your system.Some alternative keys that can be used to force BIOS update (only the System Block will be updated so it's quite safe):CTRL+Home= restore missing code into system block and clear CMOS when programming went ok.CTRL+Page Up= restore missing code into system block and clear CMOS or DMI when programming went ok.CTRL+Page Down= restore missing code into system block and do not clear CMOS and DMI area when programming went okBut what about that progress bar on the screen?If your system has AMIBIOS8 based firmware you'll see a progress bar on the screen during the programming process.It indicates the progress of the programming process.Award BIOS (Phoenix Technologies, Ltd. ? Award Software International, Inc.)1. Turn on the system and wait until you hear a beep and/or see the floppy light coming on (try hitting ENTER-key if there isn?t any activity, in some cases this will help). In SOME cases you may see something on the screen but generally AGP VGA is disabled by the Award Boot Block BIOS.2. Make a bootable DOS floppy (so with IO.SYS, Command.com, etc.) with Awardflash, a known working BIOS image, and an AUTOEXEC.BAT file with flashinstructions (example: ?AWDFLASH BIOS.BIN /py /sb? - AWDFLASH is the name of the flasher, BIOS.BIN is the name of the BIOS file, /py /sb are optional commands; 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. Jumping the Solder Beads on the CMOS It is also possible to reset the CMOS by connecting or "jumping" specific solder beads on the chipset. There are too many chipsets to do a breakdown of which points to jump on individual chipsets, and the location of these solder beads can vary by manufacturer, so please check your computer and motherboard documentation for details. This technique is not recommended for the inexperienced and should be only be used as a "last ditch" effort. Using a professional service If the manufacturer of the laptop or desktop PC can't or won't reset the BIOS password, you still have the optionCMOS AMI BIOS PASSWORD DECIPHERER V2.02 - Elektrotanya

For example, if the server hangs because of incorrect settings and does not boot, use this jumper to invalidate the settings and reboot with defaults. Caution Clearing the CMOS removes any customized settings and might result in data loss. Make a note of any necessary customized settings in the BIOS before you use this clear CMOS procedure. Procedure Step 1 Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server. Disconnect power cords from all power supplies.

And not pass it on to the users. That way you protect your PC's and the users won't be able to set their own passwords.Just occured to me that to be able to use the Kill Cmos software I have to boot from floppy which I cant do as multiboot has been disabled in the Bios and I cannot get into the bios as it is password protected.ssssooooooo - cant use that routeThe only options availible then is to either wait for the 3rd party company that supplied the laptop to see if they have records of password, open the laptop and remove the RTC battery or contact HP who will most like charge an extortionate amountOh wellthanks anywayRemoving the battery won't be of any help. That would just reset the CMOS, but not the password.OhAccording to the HP nc4200 service manual it says that removing the battery will clear all passwords and CMOS Settings.>>Removing the battery won't be of any help. That would just reset the CMOS, but not the password.As far as i know, removing will clear the password...But rindi is more knowledgable in those issues...I trust him...I don't know i can post more links or advice a program...It may be against EE policy...Best regards...Any suggestions would be great - I really dont want to open up the laptop as it involes at least 10 steps before getting to the battery.How about this - I have other nc4200 models and they dont have a password.
