3 as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance. The amount of video memory allocated depends upon the amount requested by the operating system. When the memory is no longer required, it is returned to the operating system for use by other applications or system functions. DVMT allocates memory based on system needs. This BIOS option allows you to adjust the amount of memory available for DVMT. Fixed is a memory allocation method addition to the Unified Memory Architecture (UMA) concept, wherein a static amount of page-locked graphics memory is allocated during driver initialization. This fixed amount of memory will provide the user with a guaranteed graphics memory at all times, and will no longer be available to the OS. DVMT is an enhancement of the UMA concept, where in the graphics driver allocates memory as needed for running graphics applications. If a user is not performing any graphics-intensive operations, most of the DVMT memory can be utilized by the OS for other uses. We recommend using DVMT setting for better overall system performance. ► DVMT/FIXED Memory Select graphics memory size for Fixed or DVMT usage. This setting is only applicable for WinXp.

► SMBUS Controller
The System Management Bus is a specific implementation of an I
2
C bus. The SMBus speci-
fication describes the data protocols, device addresses, and electrical requirements that are
superimposed on the
I
2
C bus specification. The SMBus is used to physically transport com
-
mands and information between the Smart Battery, SMBus Host, Smart Battery Charger, and
other SMBus Devices. This item is used to enable/disable System Management Bus controller.
► SLP_S4# Min. Assertion Width
SLP_S4# is a signal for power plane control. This signal shuts off power to all non-critical
systems when in the S4 (Suspend to Disk) or S5 (Soft Off) state.
