Video Interface
An on-board video controller integrated into the chipset provides high performance video output
for the EBX-22. Video output options include SVGA analog, LVDS flat panel, and DVI/HDMI.

ONFIGURATION
The video interface uses PCI interrupt INTA#. CMOS Setup is used to select the IRQ line routed
to INTA#. The EBX-22 uses shared memory architecture. This allows the video controller to use
variable amounts of system DRAM for video RAM. The amount of RAM used for video is set
with a CMOS Setup option.
The EBX-22 supports three types of video output, SVGA, LVDS Flat Panel Display and
DVI/HDMI. A CMOS Setup option is used to select which output is enabled after POST.

ELECTION
Jumper V6[3-4] can be removed to allow the system to boot the secondary video BIOS. Unlike
the primary video BIOS, the secondary video BIOS can be reprogrammed in the field. Using the
primary video BIOS, screen resolutions of up to 1600 x 1200 at 32 bits are available. (These
maximums may be reduced if both outputs are enabled.) Using the secondary video BIOS enables
the LVDS output. These may be combined with CRT or DVI (but not both) at a matching
resolution.

UTPUT
See the diagram on page 21 for the location of connector J7. An adapter cable, part number CBR-
1201, is available to translate J7 into a standard 15-pin D-Sub SVGA connector. Jumper V4 is
used to select between CRT (default) and analog TV output. Setting the jumper to TV (V4[2-3])
produces YPbPr (component) video output and requires the use of a 15-pin D-Sub to component
video adapter cable.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
