I'm not sure what my problem is but I used a stick to install my os on my older IDE drive, running to one IDE socket on my motherboard. I have added a second internal hdd; an SATA with a necessary converter to a 2nd IDE socket on my motherboard. Thus i keep my important files on a new, separate internal hdd. However with my present connecting cables, my only option is to add my IDE dvd drive to the ribbon cable running to my 1st hdd. When i attempt this, os load halts at a flashing cursor. I can only use my dvd drive by unplugging my SATA drive and using the 2nd IDE socket.
