The AMD Embedded G-Series Processors with AMD Radeon™ HD 6000 Series
Graphics combine the central processing unit (CPU) with the graphics
processing unit (GPU) in a single-chip Accelerated Processing Unit (APU)
package. The APU connects to the AMD A55E Fusion Controller Hub through
the Unified Media Interface (UMI) to provide connections to the different
system devices. Dimensions of the board are 170mm x 170mm.
AMD Embedded G-Series processor-based systems include the DDR3 memory
interface, PCIe, UMI, DDI (Digital Display Interface), power delivery and
miscellaneous test signals that connect to the processor.
The AMD A55E Fusion Controller Hub is designed to deliver the quality and
performance needed for everyday computing, ultitasking, and multimedia
functionality. It also provides expanded I/O connectivity for advanced usage
models to take advantage of modern peripheral devices.
The main features of the board are:
Supports Dual Core AMD Embedded G-Series Processors
Supports up to DDR3-1066 MT/s
Two DDR3 SDRAM DIMMs, Max.8GB memory

BIOS SETUP
BIOS Introduction
The BIOS (Basic Input/Output System) installed in your computer
system’s ROM supports Intel processors. The BIOS provides critical
low-level support for a standard device such as disk drives, serial ports
and parallel ports. It also password protection as well as special support
for detailed fine-tuning of the chipset controlling the entire system.
BIOS Setup
The BIOS provides a Setup utility program for specifying the system
configurations and settings. The BIOS ROM of the system stores the
Setup utility. When you turn on the co mputer, the BIOS is immediately
activated. Pressing the <Del> key immediately allows you to enter the
Setup utility. If you are a little bit late pressing the <Del> key, POST
(Power On Self Test) will continue with its test routines, thus preventing
you from invoking the Setup. If you still wish to enter Setup, restart the
system by pressing the ”Reset” button or simultaneously pressing the
<Ctrl>, <Alt> and <Delete> keys. You can also restart by turning the
system Off and back On again. The following message will appear on
the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to
select, the <PgUp> and <PgDn> keys to change entries, <F1> for help
and <Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

If the system cannot boot after making and saving system
changes with Setup, the AMI BIOS supports an override to
the CMOS settings that resets your system to its default.
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both AMI and your system manufacturer
to provide the absolute maximum performance and
reliability. Changing the defaults could cause the system to
become unstable and crash in some cases.

The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sorts of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user
will restart the WDT at regular intervals before the timer counts to zero.
