That would be an amazing feat if everything was actually working. (Didn't know some of those real old versions would even support that hardware).
At one time I had 9 OS's on a system I was screwing around on, using a combo of Boot Magic and XP (then whistler) boot loader.
I had every piece of hardware working in every system but my big mistake was using ME as the primary.
(Should have used 98SE)
