Intel SX220 manual Video, Scsi Controller, IDE Controller

Video

The SCB2 motherboard uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM that supports all standard IBM VGA modes. The embedded SVGA video subsystem supports:

•Pixel resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D

•CRT and LCD monitors up to 100 Hz vertical refresh rate

The server board supports disabling of the onboard video through the BIOS setup menu or when a plug in video card is installed in any of the PCI slots.

SCSI Controller

The server board includes an embedded Adaptec AIC-7899W controller providing dual Ultra160 Low Voltage Differential (LVD) SCSI channels.

The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The onboard device must always be at one end of the bus. The device at the other end of the cable must also be terminated. LVD devices generally do not have termination built-in and need to have a termination source provided. Non-LVD devices generally are terminated through a jumper or resistor pack on the device itself.

IDE Controller

The system includes a single channel enhanced IDE 32 bit interface controller for intelligent disk drives with disk controller electronics onboard. The controller has a connector located on the system board that supports a master and a slave device. The device controls:

•PIO and DMA transfer modes

•DMA-33 capable

•Mode 4 timings

•Transfer rates up to 33 MB/s

•Buffering for PCI/IDE burst transfers

•Master/slave IDE mode

•Up to two devices.
