INTRODUCTION
Introduction
Product Description
The IB892-10T (Atom E640T, 1.0GHz) and IB892-13T (Atom E660T
1.6GHz) are 3.5-inch disk size SBCs that support wide operating
temperature [- 40 ~ +85 degree C]. They are based on the Intel® EG20T
I/O Hub and come on board with 1GB DDRII-800 addressable memory
IB892-10T/13T SBC supports and integrated graphics controller with an
LVDS interface (18/24-bit single channel). CRT output is available with
the use of SDVO (Chrontel 7022A). The boards also have Gigabit LAN
connectivity.
High speed communication and external connections are provided by 4
USB ports, high definition audio, Mini PCI-e, 4 COM ports - with COM1
supporting RS232/422/485 while others RS232, RJ45, CRT, Micro SD
slot, CAN Bus, SATA and a CFast socket.

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 computer, 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> or <F2> 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.

Note:
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.
Warning:
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.

This setup allows you to record some basic hardware configurations in

C. Watchdog Timer Configuration
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.
