(RAID 1). There is no loss of PCI resources (request/grant pair) or add-in card slot.
Intel RAID Technology functionality requires the following items:
®
Intel 6300ESB
Intel RAID Technology Option ROM must be on the platform
®

Video Controller

Both server boards provide 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.
Video is accessed using a standard 15-pin VGA connector found on the back edge of the server
board. Onboard video can be disabled using the BIOS Setup Utility which is accessed during
POST or when an add-in video card is installed in any of the PCI slots.
