Video The system has an integrated ATI Rage IIC 64 bit high-performance SVGA subsystem that supports the following: • BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and MDA • 4 MB of 10 ns onboard Synchronous Graphics Memory (SGRAM) • Pixel resolutions up to 1280 X 1024 • Analog VGA monitors (single and multiple frequency, interlaced and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz. SCSI Controller The embedded Adaptec AIC-7899 dual function SCSI controller provides both Ultra2 (LVDS) wide and Ultra wide (SE) SCSI interfaces as two independent PCI functions. 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 end of the cable must be terminated. LVDS devices generally do not have termination capabilities. Non-LVDS devices generally are terminated through a jumper or resistor pack. 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. 12 Description
