NOTES:
LSI Software RAID Configuration Utility can set FGI Rate
(Foreground Initialize) and BGI Rate (Background Initialize
Priority). But Universal RAID Utility can't set it.
Universal RAID Utility can set Initialization Priority, but it can't set
it to the LSI Embedded MegaRAID™. Therefore, Universal RAID
Utility doesn't display [Initialization Priority] in the property of
RAID Controller.
