EPM-15 Reference Manual 32

Video Interface

An on-board video controller integrated into the chipset provides high performance video output

for the EPM-15. (The EPM-15 can also be operated without video card attached. See “Console

Redirection.”)

ONFIGURATION

The EPM-15 uses a shared-memory architecture. This allows the video controller to use 16 MB

of system DRAM for video RAM.

The EPM-15 supports two types of video output, SVGA and LVDS Flat Panel Display.

IDEO BIOS SELECTION

Jumper V4[3-4] can be removed to allow the system to boot off of the Secondary Video BIOS.

Unlike the Primary Video BIOS, the Secondary Video BIOS can be reprogrammed in the field.

SVGA

OUTPUT CONNECTOR

See Figure 7 for connector location information. An adapter cable, part num

ber CBR-1201, is

available to translate J1 into a standard 15-pin D-Sub SVGA connector.

This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
