Intel® Server Board S2600GZ/GL TPS Product Architecture Overview 3.4.2 Graphics Controller and Video Support The integrated graphics controller provides support for the following features as implemented on the server board:  Integrated Graphics Core with 2D Hardware accelerator  DDR-3 memory interface with 16 MB of memory allocated and reported for graphics memory  High speed Integrated 24-bit RAMDAC  Single lane PCI-Express host interface running at Gen 1 speed The integrated video controller supports all standard IBM VGA modes. The following table shows the 2D modes supported for both CRT and LCD: Table 11. Video Modes 2D Mode 640x480 2D Video Mode Support 8 bpp 16 bpp 24 bpp 32 bpp X X X X 800x600 X X X X 1024x768 X X X X 1152x864 X X X X 1280x1024 X X X X 1600x1200** X X ** 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 labeled "FP_Video" 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: Table 12. Video mode On-board Video Dual Monitor Video Enabled Disabled Enabled Disabled Shaded if on-board video is set to "Disabled" Revision 1.1 41 Intel order number G24881-004
