: all bios passwords can be removed easily,
: 1-create a dos system disk,
: 2- copy "debug" (this is a dos command found in windows\command directory) onto the system disk you created,
: 3- boot the machine with this disk,
: 4- at dos prompt type: debug then enter, you will see a blinking dash
: 5- type: o 70 2e then enter, (also seen: o 70 18)
: 6- type: o 71 ff then enter,
: 7- type: q then enter,
: 8- remove the floppy and reboot! Power the system off and on by unplugging and re-plugging the system into the power outlet

if you are able to bring the DOS prompt up, then you will be able to change the BIOS setting to the default. To clear the CMOS do the following:
Get DOS prompt and type:
DEBUG hit enter
-o 70 2e hit enter
-o 71 ff hit enter
-q hit enter
exit hit enter
Restart the computer. It works on most versions of the AWARD BIOS.
-------------------------------------------
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.
Get DOS prompt and type:
DEBUG hit enter
-o 70 2e hit enter
-o 71 ff hit enter
-q hit enter
exit hit enter

cant get past bios lock screen
Dude, if I am able to get past the bios lock screen, i can do many things. Your boot disc will come handy only if you are able to get into bios and change the boot priority to cd rom. or get into one time boot menu and boot from cd or usb. but in my case, i am not able to get past this bios lock screen. it says this machine #FYD59N1-595B is protected by a password authentication system. you cannot access the data on this system without the correct password.
Please type in the system or administrator password and press enter.
NO MATTER WHAT I DO, I CAN NOT GET PAST THIS SCREEN AND NOT ABLE TO BOOT FROM ANY BOOTABLE DISC.
