DMA PIO Problem - registry changes

I recently ran into the same DMA /PIO problem with a friends computer.

The registry hack that'll prevent your hard drive from going into PIO mode is below. What's funny is that I don't remember if this was before or after my changes to the registry. :p

In any case, atleast this'll point me to the right place the next time I see this happening on someone else's computer.
