Video Controller The S845WD1H server board provides an ATI Rage XL PCI graphics accelerator, along with 8 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 8 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 S845WD1H 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. Table 11.
