Dell 840 manual Configuring the Boot Drive, Removing a Hard Drive from the Drive Bay

Configuring the Boot Drive

The drive or device from which the system boots is determined by the boot order specified in the System Setup program (see "Using the System Setup Program" on page 29). To boot the system from a hard drive or drive array, the drive(s) must be connected to the appropriate controller:

•To boot from a single SATA hard drive, the master drive (drive 0) must be connected to the SATA_0 connector on the system board. To identify system board connectors, see "System Board Connectors" on page 118.

•To boot from a single SAS hard drive, the drive must be connected to a SAS controller card. See the documentation that accompanied the controller card.
