2.11.4.1 Graphics Memory Usage
The processor supports the Dynamic Video Memory Technology (Intel® DVMT) with up to 352
MB memory. This technology ensures the most efficient use of all available memory for
maximum 3D graphics performance. DVMT dynamically responds to application requirements
allocating display and texturing memory resources as required.
2.11.4.2 VGA Analog Interface and Connector J6
The 15-pin female connector J6 is used to connect a VGA analog monitor to the CP3002.
* Pin 10 is normally defined as Ground but is used on the CP3002 as detection signal of a con-
nected monitor if the uEFI BIOS setting for the CP3002 is “AUTO” (the uEFI BIOS default set-
ting is “FRONT”).
Note ...
If the automatic VGA detection mechanism on the CP3002 is used, the user
must ensure that the VGA cable and the connected monitor have a GND signal
on pin 10. Otherwise the interface is not operable.
Note ...
The VGA interface can be used either on the front panel or on the rear I/O. The
VGA signals are switched to front or rear I/O, depending on the uEFI BIOS set-
ting.
