System Overview
1.4 System
Architecture
ROBO-8717VG2A adopts Intel 965 GMCH (Graphics Memory Controller Hub) and
ICH8 (I/O Controller Hub) chipset for processor, display, memory and peripheral
I/O interfaces such as PCI Express, PCI bus, SATA ports, USB ports, and LPC (Low
Pin Count) interface.
Dual Realtek RTL8111 Gigabit Ethernet controllers are attached to the PCI Express
x1 interface to add Ethernet connectivity. Meanwhile, Winbond W83627, Super I/O
on LPC interface provides I/O such as PS/2 keyboard & mouse, floppy, parallel and
serial ports.
Audio codec, Realtek ALC262 based on HDA (High Definition Audio) to provide 2-
channel audio function such as Line-in/Line-out/MIC via header on-board.
