Hi, hope this has not been covered before
My 1TB blue drive was not seen by BIOS & stopped my SATA dvd writer from being seen by XP
I have a very old M/B:
I tried all other solutions (swapping ports, cables, etc) to no avail
Eventually, I tried both jumpers (5&6) AND (7&8) at the same time
It worked, wat a relief!
Hope this helps someone
