Is there any way to boot to dos while there is a Bios Password in Place?

Of course. Boot to a floppy disk.

Oh wait... XP. No DOS in XP. What exactly are you trying to do? Why not just get rid of the BIOS password?

You can't boot to anything if there is a bio password that you don't know. That's the purpose of a bios password. If you know the bios password just go to the bios, make the floppy the first boot and have a boot floppy in there. It should boot to a ms-dos promp.

It depends on whether the password is a "System" password you must type before you can use the computer, or a "Bios" access password you must type to get into your bios, or both.
If there is a "system" password, you probably can't boot a floppy until you enter the password.
If it is a "bios" access password, the bios must have a floppy drive before the hard drive in the boot order in the bios in order for you to be able to use a bootable Dos floppy - if it isn't set that way, booting with a floppy won't work.
If it has both a "system" and "bios" access password, in order to change anything in the bios Setup, you have to enter the "system" password - the "bios" access password will only allow you to view thw bios settings.

You could also boot a bootable CD that has Dos on it, if a CD drive is already before the hard drive in the boot order in the bios Setup.

If this is a desktop, it is easy to get rid of the password(s).
If this is a laptop, passwords can only be removed on older ones (e.g. at least 5 years old)if you don't know them - on newer ones the passwords are stored on a chip on the mboard that does not need to be powered to retain it's information.

If this is a laptop, and it is less than about 5 years old, if there is a password you must enter to access the hard drive(s), it cannot be removed by anyone, including the experts - the password is hidden on the hard drive itself and wiping the drive will not get rid of it - you must install another hard drive that has no password.

open the case, look up the mobo model, google for the manual, set the correct jumper to clear cmos, press the power button, revert jumper settings and boot without password. :-)

Today's subliminal thought is: 'Calm down ... it's only ones and zeros.'

As mattie suggests. Be careful. If you don't understand exactly your motherboard jumper use you may smoke test it. Normally on newer machines it is done with the power off but check, I mean realy check the manual.
Might have to remove a small square module or a watch type of battery.

I usually try a pxe boot. Many people forget that.

I read it wrong and answer it wrong too. So get off my case you goober.

He hasn't said whether he has a desktop computer.

It takes less time to clear the bios for any ATX computer if you remove the power to the PS while you have the jumper in the clear position.

I wondered how long it would take before someone would tell this person how to break into someone elses computer. If they don't know the password it's probably not their computer.

The easiest solution would be to remove the CMOS battery for a few seconds, then put it back in, if it's a desktop.
