Chapter 1 Introduction
Welcome to the ICPMB-7660 SOCKET 478 PENTIUM 4/4-M Single Board
Computer. The ICPMB-7660 board is an AGP/PCI form factor board, which
comes equipped with high performance Processor and advanced high
performance multi-mode I/O, designed for the system manufacturers,
integrators, or VARs that want to provide all the performance, reliability, and
quality at a reasonable price.
It’s AGP interface supports 1.5V signaling with 4X data transfers ,but it’s not
support any 3.3V AGP-card.
The integrated graphics controller provides 3D, 2D, and display capabilities.
ICPMB-7660 is supports 64-bit DDR data interface(72-bit with ECC). Available
bandwidth up to 2.7GB/s.
For the application that needs high speed serial transmission, the ICPMB7660 provides USB2.0 for your choice. The high speed USB2.0 host controller
implements an ECHI interface that provides 480Mb/s bandwidth.

AMI BIOS Setup
4.1 Introduction
This chapter discusses the Setup program written in the BIOS. It will give you
a step-by-step guidance to configure your system. The user-defined
configuration is then stored in battery -backed CMOS RAM, which retains the
customized information while the power is off.
4.2 Starting Setup
The BIOS is immediately active when you turn on the computer. While the
BIOS is in control, the Setup program can be activated in one of two ways:
1. By pressing <Del> immediately after switching the system on, or
2. By pressing the <Del> key when the following message appears at the
bottom of the screen during POST (Power On Self-Test):
Press DEL to run Setup
If the message disappears before you respond and you still wish to enter
Setup, restart the system to try again by turning it OFF then ON or pressing
the "RESET" button on the system case. You may also restart by
simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not
press the keys at the correct time and the system does not boot, an error
message will be displayed and you will again be asked to...
CMOS Settings Wrong
CMOS Date/Time Not Set
Press F1 to Run SETUP
Press F2 to load default values and continue
26
4.3 Using Setup
In general, you can use the arrow keys to highlight items, press <Enter> to
select, use the Up and Down keys to change entries, press <F1> for help and
press <Esc> to quit. The following table provides more details about how to
navigate in the Setup program using the keyboard.
Key Function
Up/down Arrow Select Item
Right/Left Arrow Select Screen
Esc key Exit
Enter Go to Sub-Screen
PgUp Next Page
PgDn Previous Page
Home Go to Top of Screen
End Go to Bottom of Screen
+/- key Change Option/Field
F1 key General help on Setup navigation keys
F2/F3 key Change Colors
F7 key Discard Changes
F8 key Load the failsafe defaults
F9 key Load the optimal defaults
F10 key Save all the CMOS changes and exit
27
4.4 Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to
use and the possible selections for the highlighted item. To exit the Help
Window press <Esc> or the F1 key again.
If, after making and saving system changes with Setup, you discover that your
computer no longer is able to boot, the AMI BIOS supports an override to the
CMOS settings which resets your system to its defaults.
The best advice is to only alter settings which you thoroughly understand. To
this end, we strongly recommend that you avoid making any changes to the
chipset defaults. These defaults have been carefully chosen by both AMI and
your systems manufacturer to provide the absolute maximum performance and
reliability. Even a seemingly small change to the chipset setup has the
potential for causing you to use the override.
4.5 BIOS Menu Bar
The menu bar on top of the screen has the following main items:
Main For changing the basic system configuration.
Advanced For changing the advanced system settings .
PCI PnP This entry appears if your system support s PnP / PCI.
Boot For changing the system boot configuration.
Security Use this menu to set User and Supervisor Passwords.

Discard Changes and Exit
Select this option only if you do not want to save the changes that you made
to the Setup program. If you made changes to fields other than system date,
system time, and password, the BIOS asks for a confirmation before exiting.
Discard Changes
This option allows you to discard the selections you made and restore the
previously saved values. After selecting this option, a confirmation appears.
Select [Yes] to discard any changes and load the previously saved values.
Load Optimal Defaults
This option allows you to load optimal default values for each of the
parameters on the Setup menus. F9 key can be used for this operation.

Appendix A. Watchdog Timer
The WatchDog Timer is a device to ensure that standalone systems can
always recover from catas trophic conditions that cause the CPU to crash. This
condition may have occurred by external EMI or a software bug. When the
CPU stops working normally, hardware on the board will perform hardware
reset (cold boot) to bring the system back to a known state.
Three I/O ports control the WatchDog Timer.
443 Write
443 (hex)
The output data is a value of time int erval and the range of the value is
from 01(hex) to FF(hex) and time interval 1 sec to 255 sec.

condition does not occur, the Watch-Dog Timer must be periodically

Read
Prior to enable the Watch-Dog Timer, user has to define Timer first.
This will enable and activate the countdown timer which will

refreshed by reading the same I/O port 443H. This must be done
within the time out period that is selected by software, please refer to
the example program.
A tolerance of at least 5% must be maintained to avoid unknown
routines within the operating system (DOS), such as disk I/O that can
be very time consuming. Therefore if the time out period has been set
to 10 seconds, the I/O port 443H must be read within 7 seconds.
Note: when exiting a program it is necessary to disable the Watch-Dog
Timer, otherwise the system will reset.
Example assembly program :
TIMER_PORT = 443H
TIMER_STOP = 443H
