I have bought all new parts. No OS installed yet. BIOS is working fine. Mobo input on the IDE ribbion cable is plugged into the Mobo.The master input on the IDE is plugged into the CD/DVD drive. The jumper on the drive is set to "Master". It has power. The first boot device is CD-Rom. I have a bootable DVD in the drive. When the BIOS is starting iam pressing F8 to select boot device. Problem is that it doesn't recognize the CD/DVD drive. So how can I get the BIOS to recognize the CD/DVD Drive?
