2.3 Architecture Overview
The following block diagram shows the architecture and main components of ECB-870.
Two major chipsets on board are the 82845 Graph Memory Control Hub and 82801BA
ICH2. These two devices provide interface to Socket478 processor, supports SDRAM with
ECC, PCI bus interface, ACPI compliant power management, USB port, and Ultra
DMA/33/66/100 IDE Bus Master. The 82801BA ICH2 also supports the standard I/O
functions like PS/2 Keyboard/Mouse, two 16C550 UARTs, FDC, Parallel and Infrared
interface. In addition, the onboard Intel 82559(ER) 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.
