The rebuild starts when you kick it off, whether from the BIOS or the 
web interface to the 3dm management utility.  After you kick it off it 
basically doesn't matter what you do - whether you leave the PC sitting 
in the 3Ware BIOS or you boot an OS the rebuild will proceed.  You can 
check the status of the rebuild from 3dm's web interface.
