11 Graphics Interfaces
11.1 Video Controller
The EPIC/CE uses the graphics accelerator integrated in the Intel® 815E chipset. It delivers high
performance 2D, 3D and video capabilities. With its interface to UMA (Unified Memory Architecture), up
to 1MB of legacy system memory is used as video memory. The video memory can be extended to 32MB
by the use of the available “Intel® Extreme Graphics” drivers.
The controller can drive two of three interfaces with its graphics engines on the EPIC/CE:
®
Cathode Ray Tube (CRT) interface
®
Low Voltage Differential Signaling (LVDS) interface
-or-
®
Optional Digital Video Output (DVO) port
11.2 CRT Connector
The CRT (Cathode Ray Tube) interface is available through the standard DSUB15 connector, which is part
of the multi-function Connector X1 on the front. To find the location of the CRT interface, please see the
