Well, remember that defragging requires more than just disk I/O: it also
requires a detailed understanding of file systems. Windows XP, Windows 98,
MS-DOS, and Linux each use VERY different file systems, which require VERY
different defragment strategies.
What are my best options? FreeDos as a guest with VirtualBox, FreeDos and
dosemu on linux? Download an illegal copy of win98 and use that as a VM
guest? (though I'm still not sure about win98/DOS BIOS interrupt in
VirtualBox).
If you really want to dink with disk I/O at the BIOS interrupt level, then
I would have to think you'd want a DOS guest in a VM. Even with Win98, you
have to worry about sharing access to the drive with the rest of the
operating system.
