4.3 Connector X3
The following subsystems can be found on connector X3. The implementation of all the
subsystems comply with ETX
®
specification 2.7. The different subsystems require I/O
and IRQ resources. The necessary resources are allocated by the BIOS during the
POST routine and are configured to be compatible to common PC/AT settings. You can
use the BIOS setup to configure some of the parameters that relate to the specific
subsystems. Check the BIOS Setup Description section for more information about how
to configure a particular subsystem.
4.3.1 Graphics
The conga-X945/XA945 graphics are driven by an Intel
®
Graphics Media Accelerator
950
engine, which is incorporated into the Intel
®
82945GME chipset found on the
conga-X945/XA945.
4.3.2 LCD
The Intel
®
82945GME chipset, found on the conga-X945/XA945, offers an integrated
dual channel LVDS interface that is connected to Display Pipe B.
4.3.3 TV-Out
TV-Out support is integrated into the Intel
®
82945GME chipset and is supported on both
Display Pipe A and Pipe B.
4.3.4 Serial Ports (1 and 2)
The conga-X945/XA945 offers two serial interfaces (TTL) that are provided by the
Winbond W83627HG Super I/O controller located on the conga-X945/XA945.
4.3.5 Serial Infrared Interface
Serial port 2 can be configured as a serial infrared interface. The Infrared (IrDA)
function provides point-to-point (or multi-point to multi-point) wireless communication,
which can operate under various transmission protocols including IrDA SIR. This feature
is also implemented by the onboard Winbond W83627HG Super I/O.
4.3.6 Parallel Port/Floppy Interface
The parallel port/floppy interface can be configured as either a conventional LPT parallel
port or a floppy-disk drive port. This is software implemented and can be configured in
the BIOS setup program. See section 9.4.6 of this document for information about
configuring the parallel port/floppy interface.
Note
When using the onboard floppy interface the floppy drive must be connected via a
non-twisted floppy cable versus a twisted cable. The floppy drive will not function when
connected via a twisted floppy cable.
