    What your saying is the whole thing is bad. Well now I have one hard 
drive jumpered for Slave and this is this one. It has to be (h1,5) or 
Grub will never boot. The (h0,1) now is an empty linux partition. It is 
jumpered for....single or Master. I have no idea how it will work. If 
I'm not heard from for many days it didn't work.
