	cabling, bad termination, or signal loss.

Virtual sizing	The virtual sizing option enables RAID expansion. Virtual
	sizing must be enabled to increase the size of a logical drive or
	add a physical drive to an existing logical drive. To enable
	virtual sizing, run the BIOS Configuration Utility by pressing
	<Ctrl> <M> at bootup. Select Objects—>Logical Drive.
	Then select View—>Update Parameters. Set virtual sizing to
