Boot Options
In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive, removable drive, or the network. The default setting is for the optical drive to be the first boot device, the hard drive second, removable drive third, and the network fourth.
NOTE
Optical drives are not supported by the onboard SATA connectors. Optical drives are supported only via the USB interfaces.
