Video Interface
An on-board video controller integrated into the chipset provides high performance video output
for the EBX-11.
C
ONFIGURATION
The video interface uses PCI interrupt INTA*. CMOS Setup is used to select the IRQ line routed
to INTA*.
The EBX-11 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-11 supports two types of video output, SVGA and LVDS Flat Panel Display. A CMOS
Setup option is used to select which output is enabled after POST.
