Forgot BIOS password

I have a Compaq Presario 2200 with a BIOS password that is forgotten. I think I have to remove the CMOS battery but I can't find it. Can anybody tell me if there is any other way to reset the password, or where the cmos battery is located? I have already contacted pwcrack and they didn't have a solution for this particular model.

Is it difficult to short this battery out?

This model has a security chip which isn't effected by removing the CMOS battery, but if you want to try , here is the video guide for this laptop. It will require a full disassembly of the laptop and removal of the motherboard, as the battery is on the bottom side of the motherboard. Shorting the battery will not work either and may harm the motherboard.
Just click on the "Real Time clock Battery" link on the left side of the page.

If shorting the battery won't work, is there a solution? Is there a master password or anything like that?

No, this is the job of the security chip, which is meant to keep those other than the valid owner(who should know the password) out of the laptop. Security on newer laptops is very tough to bypass if it can be done at all.
Usually this requires a replacement of the motherboard as the security chip is soldered on the board.
Look at it this way, if the security was crappy and anyone could bypass it, then it would serve no use. Being portable laptops are prone to being stolen, so tough security is needed.

Well at least it isn't a hard drive password, that would render his data inaccessible.
If he needs data recovered, you can pull the hard drive and use a USB hard drive enclosure to access the files.
