Video Controller; Video Modes - Intel S845WD11U Product Manual

Video Controller

The S845WD1-E server board provides an ATI Rage XL PCI graphics accelerator, along with
2 MB of video SDRAM and support circuitry for an embedded SVGA video subsystem. The ATI
Rage XL chip contains a SVGA video controller, clock generator, 2D and 3D engine, and
RAMDAC in a 272-pin PBGA. One 2Mx32 SDRAM chip provides 2 MB of video memory.
The SVGA subsystem supports a variety of modes, up to 1600 x 1200 resolution in 8/16/24/32 bpp
modes under 2D, and up to 1024 x 768 resolution in 8/16/24/32 bpp modes under 3D. It also
supports both CRT and LCD monitors up to 100 Hz vertical refresh rate.
The S845WD1-E server board provides a standard 15-pin VGA connector and supports disabling of
the on-board video through the BIOS Setup menu or when a plug-in video card is installed in the
AGP slot or any of the PCI slots.

Video Modes

The Rage XL chip supports all standard IBM VGA modes. The following table shows the 2D/3D
modes supported for both CRT and LCD. The table specifies the minimum memory requirement
for various display resolution, refresh rates, and color depths.
