Due to&nbsp;system specifications actually in use, BING must initialize and communicate directly&nbsp;with the&nbsp;SATA controller.<\/p>\r\n  <p>Unfortunately,&nbsp;the hand-off mechanism as implemented by many systems is one direction only. This means that&nbsp;once one of those&nbsp;BIOSes gives up control of the SATA controller, it won't attempt to take it back. As a result, when a BIOS request is issued for a SATA drive, the BIOS hangs up.<\/p>\r\n  <p>When&nbsp;<strong>Partition Work<\/strong> is opened, BING attempts to match BIOS drives to SATA drives. If it can't--such as when a BIOS doesn't provide the correct information needed--then the BIOS is used to access the hard drive. When&nbsp;<strong>Partition Work<\/strong> is closed, BING&nbsp;releases&nbsp;direct control of the SATA controller and all future SATA hard drive requests&nbsp;are handled by the BIOS. These future hard drive requests can occur if you choose an option that requires BING to read from a drive or load information from the BING partition itself.<\/p>","protected":false},"excerpt":{"rendered":"<p>Problem: The system hangs and &quot;reboot may be required&quot; is shown in the lower left corner of the BING desktop.
