Dual Boot on Separate Hard Drives

I have a spare Dell 8100 in which I have installed a second hard drive. I have installed XP on the the C drive, and I would like to install Windows 98 on the second drive and be able to boot from either drive. I want W98 on the second drive since there are DOS games I want to play that I cannot play on XP.

Can anyone point me toward an article that describes how to do this?

Thanks in advance.
