jumper settings to clear password

Not familiar w/ that board, but you can always pull the CMOS battery for about 30 seconds to clear the settings (make sure the power is unplugged).

There are links for users guides and jumper settings etc. here:

Delete any spaces in the URL.

Hope this helps!

I always thought you just jumped j21 to clear the password. It may even be written on the board.

Did you check the user manual for your acer on acer's site? You can look up your computer by p/n and check the specs.

Hope I've helped, good luck!

Look to see if there is a jumper to pull out on the mother board itself. On some boards you have to put the jumper back on two other pins to reset the mother board. Usually the jumper is set on one/two pins to reset put on two/three pins for a few minutes then put back on the one/two pins. Otherwise take the battery out for a few minutes to reset the computer. Hope this helps!

There is another option you can use to clear the password. Boot to DOS and at the command prompt type the following:

To disable an AMI/AWARD BIOS password:
debug
o 70 17
0 71 17
Q

To disable a Phoenix BIOS password:
debug
o 70 ff
o 71 17
Q

A generic debug command that may work:
debug
o 70 2e
o 71 ff
Q

The first example worked for me. After rebooting and attempting to enter the (formerly) password protected BIOS a message displayed saying 'CMOS Checksum error. Press any key to continue..' I could then access the BIOS.

Another resource you may want to try is this site which has more on this:
www.elfqrin.com/docs/biospw.html

If you desperately need to access the BIOS and don't mind wiping it to do so then:
www.hcs.ndirect.co.uk/free.htm and look for a program called KILLCMOS.

Good luck
