tions:
1.This device may not cause harmful interference, and
2. This device must accept any interference received, includ-
ing interference that may cause undesired operation
This equipment has been tested and found to comply with the

tion manual, may cause harmful interference to radio commu-
nications. Operation of this device in a residential area is
likely to cause harmful interference in which case the user will
be required to correct the interference at his/her own
expense. The user is advised that any equipment changes or
modifications not expressly approved by the party responsi-
ble for compliance would void the compliance to FCC regula-
tions and therefore, the user's authority to operate the

Chapter 1 Introduction
1.1 Introduction
The SOM-4486 is an Intel Ultra Low Voltage Intel® Celeron® M proces-
sor System On Module (SOM) with audio controller, a 4X AGP SVGA
controller, a PCI 10/100Base-T Ethernet interface. Using an Intel ULV
Celeron® M processor, the SOM-4486 achieves quite good performance
on the SOM-ETX CPU module. On-board features include two serial
ports, one multi-mode parallel (ECP/EPP/SPP) port, four USB (Universal
Serial Bus) ports, a floppy drive controller, and a keyboard/PS/2 mouse
interface. The built-in high-speed PCI IDE controller supports both PIO
and UDMA/66 bus master modes. Up to two IDE devices can be con-
nected, including large hard disks, CD-ROM drives, and tape backup
drives. The SOM-4486 features power management to minimize power
consumption. It complies with the "Green Function" standard and sup-
ports Doze, Standby and Suspend modes. In addition, the board's watch-
dog timer can automatically reset the system or generate an interrupt if
the system stops due to a program bug or EMI.The small size (95 mm x
114 mm) and use of four high capacity connectors based on the proven
SOM-ETX form factor, allow the SOM-ETX modules to be easily and
securely mounted onto a customized solution board or our standard
SOM-DB4400 development board.
The SOM-4486 is a highly integrated multimedia SOM that combines
audio, video, and network functions. It provides 16-bit half-duplex, 8-bit
full-duplex, integrated 3D audio, and up to 1024 x 768 resolution @ 16.8
M colors with 8/16/32 MB system memory. Major on-board devices
adopt PCI technology, to achieve outstanding computing performance
and 10W power consumption when used with Intel® Celeron® M pro-
cessors.

Chapter 2 Connector Assignments
2.1 Connector Locations
The board has a number of connectors that allow you to configure your
system to suit your application.

2.3 Safety precautions
Warning! Always completely disconnect the power cord
from your board whenever you are working on it.
Do not make connections while the power is on,
because sensitive electronic components can be
damaged by a sudden rush of power.
Caution! Always ground yourself to remove any static
charge before touching the board. Modern elec-
tronic devices are very sensitive to static elec-
tric charges. Use a grounding wrist strap at all
times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in use.

Chapter 3 Software Configuration
3.1 Introduction
The SOM-4486 system BIOS and custom drivers are located in a 512 KB,
32-pin Flash ROM. A single Flash chip holds the system BIOS and VGA
BIOS. The display type can be configured via software. This method
minimizes the number of chips and eases configuration. You can change
the display BIOS simply by reprogramming the Flash chip
3.2 Utility CD disk
The SOM-4486 is supplied with a software utility on CDROM. This disk
contains the necessary file for setting up the VGA display. Directories
and files on the disk are as follows.
AW D F L A S H . E X E
This program allows you to update the BIOS Flash ROM.
4481Vxxx
This binary file contains the system BIOS.
3.3 VGA display software configuration
The SOM-4486 on-board VGA/LCD interface supports an 18bit TFT
LCD, flat panel displays and traditional analog CRT monitors. The inter-
face can drive CRT displays with resolutions up to 1280 x 1024@32 bpp.
It is also capable of driving color panel displays with resolutions of 1280
x 1024 @ 16bpp. The LCD type is configured completely via the soft-
ware utility, so you do not have to set any jumpers. Configure the LCD
type as follows:
