You can do that by resetting the BIOS. To do this:
#1)Turn off the computer
#2)Unplug the tower from the wall outlet.
#3)Open up the side cover and lay the tower down with the motherboard laying flat.
#4)(Depending on your motherboard this might be different) Next to the CMOS Battery( about the size of a nickel) there should be 3 pins with two of them covered by a little tab called a jumper.
#5)With a small, NON-MAGNETIC, Flathead screwdriver, remove the jumper from its two pins.
#6)Set the jumper so that it is one pin over from its original position.
#7)Wait about 30 seconds.
#8)After that return the jumper to its original position.
#9)Put the cover back on plug the computer into the wall and turn on your system.
The BIOS should be reset.
IF this does not work repeat up to step #3.
Remove the battery from its placeholder and waiting 30 seconds again. Return it to its place repeat step 9 and try again.
No, removing the bios battery on a laptop will not reset bios settings.
Yes. Despite how it sounds, "dumping" only copies the BIOS; it does not remove or modify it.
You would have to take it to the manufacturer to get BIOS re-loaded.
If it is a Mercury 1300 then remove the case and pop the internal BIOS battery - job done!

Remove battery for 30 seconds
The function of a bios battery is basically to reset your bios if something goes wrong and you corrupt it. Bios batteries usually contain a little bit of information on them. Therefore, when you remove a bios battery, it goes back to default settings. **Note** removing a bios battery is usually a last resort to reset your bios. There are several other ways to reset your bios such as a jumper cable or (included in some never motherboards,) a reset bios switch.

You do not, the version above A05 is written by Dell, not Phoenix. Once installed, the Dell version rewrites the BIOS with a different format and from that point on you are stuck with Dell's version of the BIOS. Unless you buy another motherboard with an older version of the Phoenix BIOS, you have to live with what you have. Unless you can remove the BIOS Chip, you currently have and solder an old Phoenix BIOS chip in its place.
