1.1 Introduction
The AEC-6930 BOXER 2 Advanced Embedded Control system
continues the BOXER design concept but focuses on the fast
expanding Machine Automation market. The AEC-6930 can
provide two PCI slot for expansion. Therefore AEC-6930’s
expandable function, compact size combined with fanless design
and highly efficient heat conduction mechanism can fulfill any
rugged technical application in industrial automation, factory
control, test instrumentation and safety surveillance.
Outstanding Ov er-spec Design
®
Intel’s
CoreTM 2 Duo processor with 1.60 GHz combined with
fanless design and high performance is widely acceptable and
dependable in this market. USB 2.0, Quad ports GbE Ethernet
and 4 Serial ports allow communication with diverse devices with
a high transfer rate. Furthermore, the AEC-6930 can concurrently
support three tiers of expansion interfaces - PCI, PCMCIA and
mini-PCI. These interfaces are fully integrated within the BOXER
series and allow an upgrade to their usefulness. It is a
leading-edge thermal and vibration design (up to 55 degree
operation and 5G RMS vibration) and also an innovation for
Machine Automation in the IPC industry. AEC-6930 plays a role
in connecting all subsystems in common applications. AAEON

Chapter 3 Award BIOS Setup 3-1
Embedded Controller AEC-6930
3.1 System Test and Initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few
short beeps or see an error message on the screen. There are
two kinds of errors: fatal and non-fatal. The system can usually
continue the boot up sequence with non-fatal errors. Non-fatal
error messages usually appear on the screen along with the
following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue the
boot up sequence.
System configuration verification
These routines check the current system configuration against
the values stored in the CMOS memory. If they do not match,
the program outputs an error message. You will then need to
run the BIOS setup program to set the configuration information
in memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The AEC-6930 CMOS memory has an integral lithium battery
backup for data retention. However, you will need to replace the
complete unit when it finally runs down.
Chapter 3 Award BIOS Setup 3-2

Caution:
In AAEON products with Intel embedded graphics chipset, when system
booting before CRT / LCD monitor has disconnected to VGA, it will caus e
Intel graphics chipset automatically detected without CRT / LCD
connection and set CRT output to disable. Therefore, CRT / LCD screen
will go black and never recovered on Windows.
Because it's a limitation on application for Intel em bedded graphics driver

Appendix A Programming the Watchdog Timer A-1
Embedded Controller AEC-6930
A.1 General Information
The AEC-6930 utilizes Fintek F75111 chipset as its watchdog timer
Controller.
The other Watchdog timer is set to second or minute and the range is 0
to 256 seconds or minutes.
When the timeout has occurred, that will generate a status bit to indicate
it and write one will be clear.
A.2 Access Interface
The F75111 provides one serial access interface, I2C Bus, to read/write
internal registers. The address of Serial Bus is
configurable by using power-on trapping of standby power VBS3V. The
pin 3 (GPIO13/I2C _ADDR) is multi-function pin. During the
VSB3V power-on, this pin serves as input detection of logic high or logic
low. This pin is default pull-down resistor with 100K ohms
mapping the Serial Bus address 0x9C (1001_1100). Another Serial Bus
address 0x6E (0110_1110) is set when external pull-up resistor with
10K ohms is connected in this pin.
