** Video resolutions at 1600x1200 and higher are only supported through the external video
connector located on the rear I/O section of the server board. Utilizing the optional front panel
video connector may result in lower video resolutions.
The server board provides two video interfaces. The primary video interface is accessed using a standard 15-
pin VGA connector found on the back edge of the server board. In addition, video signals are routed to a 14-
pin header on the leading edge of the server board, allowing for the option of cabling to a front panel video
connector. Attaching a monitor to the front panel video connector will disable the primary external video
connector on the back edge of the board.
The BIOS supports dual-video mode when an add-in video card is installed.
 In the single mode (dual monitor video = disabled), the on-board video controller is disabled when an
add-in video card is detected.
 In the dual mode (on-board video = enabled, dual monitor video = enabled), the on-board video
controller is enabled and is the primary video device. The add-in video card is allocated resources and
is considered the secondary video device. The BIOS Setup utility provides options to configure the
feature as follows:
