I have a system that I build asus A8r-mx motherboard with a amd Athlon 64 processor speed 3500. 1gig of memory, My question is I have two optical drive installled one a dvd recorder and a nec nr-9300A cdrw, the bios will reconize both, but window vista will not see the cdrw not even in disk management, I can't even open drive while in window as if there is no pwr to it. I can open drive during boot up in post( pwr on self test)
