I have attached two drives (CD-RW & DVD) To my new motherboard (Asus A7V8x). CD-RW as Secondary Master and DVD as Secondary Slave. These are UDMA2 (66) and are rooted by a normal 40 conductor-IDE Cable. UDMA 66, I know to be supported by my Mobo. On the Ultra-DMA Connector, I have two HDD, one as Primary Master and the other Primary Slave connected by a 80 conductor-UDMA Cable. I have checked in the BIOS, they are present/detected. Also, when I boot up, the POST shows that the two Disk Drives have been recognised. However, when I enter Windows, in 'My Computer', nothing! All connections seem to be correct with cables, and I have tried known-working alternative cables. All Jumper-settings seem to be correct? I am assuming this is a software problem, as that is what seems to be the most obvious here, but of what kind, I have not a clue? Do I need to install some sort of driver here to aid recognition in Windows? I have looked into the 'cd-rom controllers' given in the 'hardware wizard' from 'Control Panel', where I have 3 possible controllers listed, these being Mitsumi, Panasonic and Sony, by which, none of my drives are manufactured? (mine are NEC and Samsung) Any advice would be appreciated here please, as this has stumped me? Thanks for reading.
