I have a fresh build here. The bios recognizes my SSD but not my dvd/cd drive. I have been up and down the bios with no resolution. Any help would be appreciated!

I had that same problem once with a Gigabyte MB and one other that I can't remember the manufacturer of.
When connecting a SATA Optical drive to the SATA ports, I found that sometimes they won't be 'bootable' plugged into the 1st set of ports on the M/B if those ports are set as AHCI. If possible, move the optical drive to a set of SATA ports you can change to IDE.

Put SSD on SATA Port #1
Put Optical Drive on SATA 5 or 6

Go to SATA Configuration in the BIOS
Change SATA Ports5-Port6 from [AHCI] to [IDE]
Save and Exit BIOS.

Is the drive's power cable firmly inserted? Do you know if the optical drive is a working device?
