When I had my Amiga 1200, I had to put in a buffered ide dual drive, on this I had to put the dh0: drive on one branch and the CD on the other branch with both set to master. Now all I had was the original chip set with no expensive boards, but after I did that all lock ups went away and I finally booted into OS 4.1. If you put both on the same branch of the ide controller, then OS4.1 gets lost. It is one of the most finicky OS I ever had the pleasure of using. I still have my copy but dread trying to install it again. It took me about 2 months of playing with this disaster of an OS and to tell you the truth I would rather try to install a DOS system for gaming then this OS. Read every sentence in the OS4.1 instruction manual, you skip one word and you are doomed I tell ya.
