bios password removal

Hi,
My computer is second hand.I needed it for school and stuff.
I can not access the bios because it's password protected.
I try ed http:\\www.cgsecurity.org advice to remove the
password protection. But it does not work.
Just wondering if there is another way to remove it?
Or am I doing something wrong?
Thanks in advance and Merry Christmas!

Some Bios have backdoor passwords. Some can be reset by removing the
CMOS battery, some can be "jumped". See here if anything can help:

WARNING!!! If this is a laptop just bring it to an authorized service
center or check the manufacturer's web site! You might be in for a
nasty surprise if you try to hack BIOS password on certain laptops.

Most BIOS passwords can be bypassed - by means generally available (but it
probably means opening the case)
e-mail me!

Try this

http://www.mdgx.com/newtip20.htm#DBP

Courtesy of Chris (scary_fast_99@yahoo.com).
"This DOS trick deletes (resets to default) your motherboard BIOS CMOS
password, to grant access to your computer and/or BIOS Setup once again, in
case you have forgotten or lost it. :)
Exit MS Windows or reboot to native MS-DOS mode, using the "Command prompt
only" option from the Windows 95/98 Startup Menu: hold Shift + F5 at the
same time while your PC boots.
Then type at the C:\> prompt:

DEBUG

and hit Enter. You'll see a dash (-) at the DEBUG prompt. Now type:

o 70 2e

which will show as -o 70 2e at the DEBUG prompt. Hit Enter. Then type:

o 71 ff

and hit Enter. Finally type:

Q

and hit Enter one last time to quit DEBUG back to the C:\> prompt.
Now you're ready to reboot your PC, and press the appropriate key or key
combo (look it up in your motherboard manual if you don't know it) to access
your BIOS Setup. You'll notice the password is gone. :)"

NOTE: This works ONLY with MS-DOS 5.xx/6.xx, MS-DOS 7.xx [a.k.a. MS Windows
9x] or any other real mode OS.

FYI: More info.

I'd be VERY surprised if this worked on any modern motherboard!

Noel
It did work in some cases in the ngs somewhere
else. But I never tried it myself.
Debug command are very tricky.
