1.3 System Architecture
The following illustration of block diagram will show you how WEB-6681
Series give you a highly integrated system solution. The most up-to-date system
architecture of WEB-6681 Series include two main VLSI chips, VT8601A North
Bridge and VT82C686B South Bridge, to support VIA EDEN/EZRA processor,
SDRAM with non ECC, PCI bus interface, ACPI compliant power management,
USB port, SMBus communication, and Ultra ATA/33/66/100 IDE Bus Master. The
VT82C686B South Bridge will support PS/2 Keyboard/Mouse, one UARTs and

in a processor system. The South Bridge, VT82C686B, provides PCI-to-ISA bridge
solution for the best industry application. It supports Ultra ATA 33/66/100 IDE
master interface, full Plug-and-Play compatibility, and Advanced Programmable
Interrupt Controller (APIC) interface on WEB-6681 Series`. It also supports 2-port
Universal Serial Bus (USB), and internal Real-time Clock (RTC) to maintain date
and time of a system.
The South Bridge VT82C686B, which integrates one high-speed serial ports,
one parallel port, 8042 keyboard controller with PS/2 mouse ports. This parallel
port supports one PC-compatible printer port (SPP), Enhanced Parallel Port (EPP)
and Extended Capabilities Port (ECP). Beside, it offer H/W monitor function.
VT82C686B standard 16-bit ISA bus slot is applied for all of slower I/O
operations. In WEB-6681 Series, it contains Watch-dog Timer (WDT) Enabled by
jumper setting and trigger by software. The on-board AGP device, graphics display
port. The on-board PCI device, Triple Ethernet controllers, powered by Intel 82559
