Intel® Server Board S2600CW Functional Architecture Intel® Server Board S2600CW Family TPS
46 Revision 2.4
3.4.12 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.
1. 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.
3.4.12.1 Dual Video and Add-In Video Adapters
There are enable/disable options in the <F2> BIOS Setup PCI Configuration screen for “Add-in
Video Adapter” and “Onboard Video”.
When Onboard Video is Enabled, and Add-in Video Adapter is also Enabled, then both
video displays can be active. The onboard video is still the primary console and active
during BIOS POST; the add-in video adapter would be active under an OS environment
with the video driver support.
When Onboard Video is Enabled, and Add-in Video Adapter is Disabled, then only the
onboard video would be active.
When Onboard Video is Disabled, and Add-in Video Adapter is Enabled, then only the
add-in video adapter would be active.
Configurations with add-in video cards can get more complicated on server boards that have
two or more CPU sockets. Some multi-socket boards have PCIe slots capable of hosting an
add-in video card which are attached to the IIOs of CPU sockets other than CPU Socket 1.
However, only one CPU Socket can be designated as “Legacy VGA Socket” as required in
POST.
