Parameter	Description	Options
On-Chip Frame Buffer Size	This BIOS feature controls the amount of system memory	1MB, 4MB, 8MB,
	that is allocated to the integrated graphics processor when	16MB, 32MB,
	the system boots up. Please visit http://www.rojakpot.com/	64MB, 128MB (for

	settings.	1MB, 8MB (for
		DVMT)
DVMT Mode	The BIOS feature that controls all this is the DVMT Mode	Fixed Mode
	BIOS feature. It allows you to select the DVMT operating	DVMT Mode
	mode.	Combo Mode
	When set to Fixed Mode , the graphics driver will reserve a
	fixed portion of the system memory as graphics memory.
	This ensures that the graphics processor has a guaranteed
	amount of graphics memory but the downside is once
	allocated, this memory cannot be used by the operating
	system even when it is not in use.
	When set to DVMT Mode, the graphics chip will
	dynamically allocate system memory as graphics memory,
	according to system and graphics requirements. The
	system memory is allocated as graphics memory when
	graphics-intensive applications are running but when the
	need for graphics memory drops, the allocated graphics
	memory can be released to the operating system for other
	uses.
	When set to Combo Mode , the graphics driver will allocate
	a fixed amount of memory as dedicated graphics memory,
	as well as allow more system memory to be dynamically
	allocated between the graphics processor and the
	operating system.
	It is recommended that you set this BIOS feature to DVMT
	Mode for maximum performance. Setting it to DVMT Mode
	ensures that system memory is dynamically allocated for
	optimal balance between graphics and system
	performance.
DVMT/FIXED Memory Size	It allows you to set the maximum amount of system	64MB
	memory that can be allocated as graphics memory, but only	128MB
	for the Fixed or DVMT operating modes. When the DVMT +
	Fixed mode is selected, this BIOS feature is grayed out
	because when in that operating mode, the graphics driver
	automatically allocates a total of 128MB of graphics
	memory.
	When set to 64MB, up to 64MB of system memory can be
	used as graphics memory.
	When set to 128MB, up to 128MB of system memory can
	be used as graphics memory.
