Chapter 1
System Overview
1.1 Introduction
COM Express Type 6, have not holds by PICMG (PCI Industrial Computer
Manufacturer Group) yet but they will defines new industrial computer platform in
“Module board”and “Carrier board”architecture. The “Module board”equipped
processor or its socket, chipset, memory or memory socket and single Ethernet
controller on it. The On-The-Shelf Module board allows users to create their own
Carrier board easily and quickly since most critical parts are ready on Module board.
COM Express Module board offers expansion interfaces such as PCI Express, PCI,
SATA, IDE, LPC, LVDS, HDMI, DP, DVI, and Audio etc. that could support variety
functions depending on Carrier board design.
The Carrier board was customized design to fit in different mechanical
requirements. In the meanwhile, its variety functions were also customized to meet
the application. Compares to the platform that designed from nothing, COM
Express architecture platform only needs to develop Carrier board. Users could
keep their know-how which related to their core competence in the Carrier board.
PCOM-B630 is Type VI COM Express Module board with ECC support equipped
Intel Haswell Bridge BGA processor (Core i7 2.0GHz 4 Core、Core i5 1.8GHz 2 Core
processor on-board), two DDR3L SO-DIMM sockets, one Gigabit Ethernet controller
on it to provide expansion interfaces –PCI Express (x16 / x1), Three Multiple
display ports (supports SDVO/HDMI/DP/DVI), SATA and so on.
1.2 Check List
The PCOM-B630VG series package should cover the following basic items
One PCOM-B630VG module board
If any of these items is damaged or missing, please contact your vendor and keep all
packing materials for future replacement and maintenance.

System Installation
This chapter provides you with instructions to set up your system. The additional
information is enclosed to help you set up onboard PCI device and handle Watch
Dog Timer (WDT) and operation of GPIO in software programming.
3.1 Install PCOM-B630VGVG with a Carrier Board PCOM-C600
Place PCOM-C600 in a flat surface and screw on the four (4) cooper pillars.

BIOS Setup Information
PCOM-B630VG User’s Manual
Do the same with PCOM-B630VG and Make Sure the Memory DDR3L SO-
DIMM Module is ECC

BIOS Setup Information
PCOM-B630VG User’s Manual
Insert the ECC DDR3L SO-DIMM Memory Module in the right direction and make
sure be well installed.
Then mount the PCOM-B630VGVG onto PCOM-C600
Make sure that row connector is well installed

BIOS Setup Information
PCOM-B630VG User’s Manual
Then screw on the four (4) cooper pillars to fix the PCOM-B630VGVG

BIOS Setup Information
PCOM-B630VG User’s Manual
3.2 Main Memory
PCOM-B630VGVG provide 2 x 204 pin DIMM sockets (Dual Channel) which
supports Dual channel 1066/1333 DDR3L-SO-DIMM as main memory, ECC (Error
Checking and Correcting). The maximum memory can be up to 16GB. Memory clock
and related settings can be detected by BIOS via SPD interface.
For system compatibility and stability, do not use memory module without brand.
Memory configuration can be set to either one double-sided DIMM in one DIMM
socket or two single-sided DIMM in both sockets.
Beware of the connection and lock integrity from memory module to socket.
Inserting improperly it will affect the system reliability.
Before locking, make sure that all modules have been fully inserted into the card
slots.
Note:
To insure the system stability, please do not change any of DRAM parameters in
BIOS setup to modify system the performance without acquired technical
information.
3.3 Installing the Module upon the Carrier Board then into the
Chassis
To install your PCOM-B630VGVG into standard chassis or proprietary environment,
please perform the following:
Step 1: Install well the PCOM-B630VGVG upon the Carrier Board, Cooler in its
correct position.
Step 2: Check all jumpers setting on proper position.
Step 3: Place the Carrier Board into the chassis and screw with the correct place.
Step 4: Attach cables to existing peripheral devices and secure it
WARNING
Please ensure that SBC is properly inserted and fixed by mechanism.
Note:
Please refer to section 3.3.1 to 3.3.4 to install INF/VGA/LAN/Audio drivers.
3.3.1 Chipset Component Driver
PCOM-B630VGVG uses Intel Haswell QM87 chipset. It’s a new chipset that some old
operating systems might not be able to recognize. To overcome this compatibility
issue, for Windows Operating Systems such as Windows XP, please install its INF
before any of other Drivers are installed. You can find very easily this chipset
component driver in PCOM-B630VGVG CD-title.

BIOS Setup Information
PCOM-B630VG uses phoenix BIOS structure stored in Flash ROM. These BIOS
has a built-in Setup program that allows users to modify the basic system
configuration easily. This type of information is stored in CMOS RAM so that it is
retained during power-off periods. When system is turned on, PCOM-B630VG
communicates with peripheral devices on the carrier board and checks its hardware
