The jumper should do it...if not, try removing the battery and then replacing it.
Good luck!

For some systems, you need to set the jumper, power up, shut down, and then set the jumper back to fully reset the CMOS.
There are also a number of password cracking utilities. Check your favorite download site.

Has a BIOS password recovery utility.

Some M/Bs have a hardwired battery backup of the replacable battery. Try removing the battery and leaving it out overnight. Then set the jumper to the reset position, booting to the BIOS display, power-off, re-set the jumper and replace the battery.

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:
I have found that 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

As well as removing the battery, remember to unplug the PC, when you let it sit overnight.

If any of the above steps fail to work, get yourself a wired jumper switch like one from the reset switch or an old turbo button jumper, cut the wires, and attach a slightly dead 9 volt battery to the end of it(only requires 6-8 volts). Then attachit where the jumper where resetting the bios would go and then pull it back off immediately. This overpowers the eeprom on the chip and sets it back to it regular pre-programmed state.
This is not recommend unless this is the last resort. This can also blank the bios chip on some models in which case a bios update and burn would need to be done.
REMEMBER, LAST RESORT ONLY

you can either set another password in its place
or
To completely remove the previous password you can remove the cmos battery and then replace it
back again.Thus your password is lost from the system memory.But before doing it either copy all the cmos settings on a floppy or take a print out because all the information stored on the cmos setup will be lost and you will have to feed in all that original settings after the password has been removed.
