2.1 Jumpers & Switches
The MIO-5251 has a number of jumpers that allow you to configure your system to
suit your application. The table below lists the functions of the various jumpers.
2.2 Connectors
Onboard connectors link the MIO-5251 to external devices such as hard disk drives,
a keyboard, or floppy drives. The t ab le be low lists the function of each of the connec-

2.4 Setting Jumpers
You may configure your card to match the needs of your application by setting jump-
ers. A jumper is a metal bridge used to close an electric circuit. It consists of two
metal pins and a small metal clip (often protected by a plastic cover) that slides over
the pins to connect them. To “close” a jumper, you connect the pins with the clip. To
“open” a jumper, you remove the clip. Sometimes a jumper will have three pins,
labeled 1, 2 and 3. In this case you would connect either pins 1 and 2, or 2 and 3.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales represent ative before you make any changes. Generally, you
simply need a standard cable to make most connections.

MIO-5251 User Manual 14
AMIBIOS has been integrated into a plethora of motherboards for decades. With the
AMIBIOS Setup program, you can modify BIOS settings and control the various sys-
tem features. This chapter describes the basic navigation of the MIO-5251 BIOS
setup screens.
AMI BIOS ROM has a built-in Setup program that allows users to modify the basic
system configuration. This information is stored in battery-backed CMOS so it retains
the Setup information when the power is turned off.

Chapter 3 AMI BIOS Setup
3.1 Entering Setup
Turn on the computer and check for the patch code. If there is a number assigned to
the patch code, it means that the BIOS supports your CPU. If there is no number
assigned to the patch code, please contact an Advantech application engineer to
obtain an up-to-date p atch code file. This will ensure that your CPU‘s system st atus is
valid. After ensuring that you have a number assigned to the patch code, press
<DEL> and you will immediately be allowed to enter Setup.
3.1.1 Main Setup
When you first enter the BIOS Setup Utility, you will encounter the Main setup screen.
You can always return to the Main setup screen by selecting the Main tab. There are
two Main Setup options. They are described in this section. The Main BIOS Setup
screen is shown below.
The Main BIOS setup screen has two main frames. The left frame displays all the
options that can be configured. Grayed-out options cannot be configured; options in
blue can. The right frame displays the key legend.
Above the key legend is an area reserved for a text message. When an option is
selected in the left frame, it is highlighted in white. Often a text message will accom-
pany it.
System time / System date
Use this option to change the system time and date. Highlight System Time or
System Date using the <Arrow> keys. Enter new values through the keyboard.
Press the <Tab> key or the <Arrow> keys to move between fields. The date
must be entered in MM/DD/YY format. The time must be entered in HH:MM:SS
format.
