See reply 1), but there are also lots of boot managers out there; @home I use Acronis OS Selector (very reasonably priced, like $30) for 98SE, 2K Pro, and Linux Lycoris (although the latter comes with its own BM).
Advantages: 98SE is perfect for the older games (more generally, programs) as there are no compatibility issues, while the NT line is better suited for work (stability, security, etc.). Plus, you can learn a system without having a second (or subsequent) machine (fancy trying out BeOS? Or Win2003?).
Disadvantages: tools like Norton System Works _can_ mess up the configuration of your other systems real good, so be careful when running batch fixes (WinDoctor, for one). Also, defragmentation can put errors in your MBR - consequently, the Boot Manager ceases to work - but a BM reinstall only takes a couple of seconds and helps. Yes, defrag does it to the OSS. Don't really know about other BMs.
good luck.

The "simple" way to dual boot W98 and XP is to:

Partition the hard drive into at least 3 partitions.
C: W98
D: XP
E: shared data files

Install W98 onto C:

After W98 is working properly, insert the XP CD, and follow the prompts to install XP as a dual boot to the C: drive.

Advantages:
Some applications just work better with an older OS.

Disadvantages:
Lost hard drive space.
Security issues for W98 with the end of support.
Hardware limitations. Your hardware needs to be compatible with both versions of Windows, and you will be forced to deal with W98s 511MB RAM limit.

While I have had to update some software, I do not miss W98 on my XP box.
As soon as I have the spare funds, I will upgrade my remaining W98 boxes to XP.
