This is necessary because most systems automatically changethe boot order when they detect a newly installed controller anddevice. Refer to the documentation for your system for informationabout starting the system BIOS. If the OS is already installed on a unit connected to thesystem, be sure that device precedes the 3ware RAID controllerin the boot sequence. If you have other disks installed on themotherboard, the 3ware RAID controller should precede themin boot order. If you will install your OS on a disk or array attached to the3ware RAID controller, specify the controller as the bootdevice. (Note that if you configured more than one unit, thedrive(s) specified as Unit 0 will be treated as the boot disk.)
