2.3Architecture Overview

The following block diagram shows the architecture and main components of ECB-865. Two major chipsets on board are the 82815E Graph Memory Control Hub and 82801BA ICH2. These two devices provide interface to Socket370 processor, supports CRT display, SDRAM with ECC, PCI bus interface, ACPI compliant power management , USB port, SMBus communication, and Ultra DMA/33/66/100 IDE Bus Master. The onboard super I/O chip, IT8712F-A, supports PS/2 Keyboard/Mouse, two 16C550 UARTs, FDC, Parallel and Infrared interface. In addition, the onboard Intel 82559 10/100BASE-TX Ethernet controller delivers high speed data transfers over the PCI bus.

The following sections provide detail information about the functions provided onboard.
