Chapter 2. Installation

This chapter describes how to install the JUKI-745E. First, the

layout of JUKI-745E is shown, then comes the unpacking
precautions that you should be careful is described. After that
comes jumpers and switches setting for JUKI-745E's configuration,
such as CPU type selection, system clock setting, and watch dog

• CPU Core Voltage Selection :

Please check the CPU Core Voltage before you install the CPU.
Currently, the new Intel MMX CPU utilizes dual voltages for core
and I/O, in other words, the I/O is 3.3V but the core is 2.8V.
This kind of CPU design will enhance the low power consumption
capability. Common type Pentium CPUs utilizes one voltage for
both I/O and Core namely, 3.3V,3.4V,or 3.5V.

Chapter 4. AMI BIOS Setup

The JUKI-745E uses the AMI BIOS for system configuration. The
AMI BIOS setup program is designed to provide maximum
flexibility in configuring the system by offering various options
which may be selected to meet end-user’s needs. This chapter is
written to assist you in the proper usage of these features.

4.1 Getting Start

When power on the system, the BIOS will enter the Power-On-
Self-Test routines. These routines will be executed for system test,
initialization and system configuration verification. After POST
routines are completed, the following message appears:

" Hit DEL if you want to run SETUP"

To access AMI BIOS Setup program, press <Del> key, then you
could see the screen to select from the following options:

When you choose Load BIOS Defaults, the system will load
minimized settings for Troubleshooting. The performance should
be very poor when you use this setting.

When you choose Load Setup Defaults, the system will load
optimized defaults for regular use. Choosing this setting, will
modify all applicable settings.

23
4.2 Standard CMOS Setup
The Standard CMOS Setup is used for basic hardware system
configuration. The main function is for Date/Time setting and
Floppy/Hard Disk Drive setting. For IDE hard disk drive setup,
please check the following possible setup procedure:

1. Use Auto setting for detection during boot up.

2. Use IDE HDD AUTO DETECTION in the main menu to
automatically enter drive specifications.
3. Manually enter the specifications from the “User” option.

4.3 Advanced CMOS Setup

This Advanced CMOS Setup is designed for customers tuning best
performance out of JUKI-745E board. As for normal operation,
customers don’t have to change any default setting. The default
setting is pre-set for most reliable operation. You can also enable
or disable system keyboard, primary display, PS/2 mouse in this
option. The system boot sequence is also modified through this
setup page to first, second, third and fourth boot device setting.

4.4 Advanced Chipset Setup

This setup function are mostly related to ChipSet(ALI 4+). These
options are used to change the ChipSet’s registers. Please
carefully change any default setting, otherwise the system could
become unstable.
