ASMB-781 User Manual 2
1.1 Introduction
The ASMB-781 motherboard is the most advanced Intel® C206 board for industrial
server grade applications that require high-performance computing. The mother-
board supports 2nd generation Intel® Xeon® E3/ Core
TM
i3 and DDR3 1066/1333
MHz memory up to 32 GB. ASMB-781 provides an ASPEED AST-1300/2300
onboard graphic controller, with 64MB onboard graphics VRAM.
ASMB-781 provides a mainstream PCIe x16 gen II expansion slot or 2 x PCIe x16
(x8 link) double-deck expansion cards for add-on graphic cards to meet higher graph-
ics performance demands. In addition, the ASMB-781 has four Gigabit Ethernet LAN
(G4 version) via dedicated PCIe bus, which offers bandwidth up to 300 MB/s, elimi-
nating network bottlenecks. High reliability and outstanding performance make the
ASMB-781 the ideal platform for industrial networking applications.
By using the Intel® C206 chipset, the ASMB-781 offers three 32-bit, 33 MHz PCI
slots; one PCIe x1 slot, one PCIe x4 slot, two PCIe x16 slot and a variety of features
such as 2 onboard SATA III interfaces (bandwidth = 600 MB/s) and 4 onboard SATA
II with software RAID; 12 USB 2.0 connectors. These powerful I/O capabilities ensure
even more reliable data storage capabilities and high-speed I/O peripheral connectiv-
ity.
The ASMB-781 also adopts Advantech’s unique, patented Sleep Mode Control Cir-
cuit for AT Power Mode. With all the excellent features and outstanding performance,
the ASMB-781 is the ideal platform for today’s industrial applications.
1.2 Features

PCIe architecture: The Intel® C206 PCH chipset supports 2 PCIe x16 slot, 1
PCIe x4 slot, 1 PCIe x1 slot, 2 SATA III and 4 SATA II connectors.

High Performance I/O capability: Four Gigabit LAN via PCIe bus, 3 PCI 32-bit/
33MHz PCI slots, and 12 USB 2.0 ports. (2*Type A USB2.0)

Standard ATX form factor with industrial features: ASMB-781 provides
industrial features like long product life, reliable operation under wide tempera-
ture range, watchdog timer functions, etc.

Automatic power on after power failure: It is often necessary to have an unat-
tended system come back into operation when power resumes after a power
failure. Advantech’s industrial motherboard allows users to set the system to
power on automatically without anyone hitting power button. Please refer to the
detailed "AT" mode settings in Table 1.5 of Section 1.8.3.
