doesn't xp have an option built into it to run pretending to be 98. im sure i remembered seeing a whole menu of options were xp kind of disguises itself as past windows versions.

and i know for sure xp allows you to actually have more than 1 win os on the computer and gives you a choice of what os to boot to at the start up.

of course you could just use standard midi cables like the rest of us mear mortals
