4. AMI BIOS SETUP
4.1 Introduction
This manual discusses AMI Setup program built into the ROM BIOS. The
Setup program allows users to modify the basic system configuration. This
special information is then stored in battery-backed RAM so that it retains
the Setup information when the power is turned off.
4.2 Starting Setup
AMI BIOS is immediately activated when you first power on the computer.
BIOS reads the system information contained in the CMOS and begins the
process of checking out the system and configuring it. When it finishes,
the BIOS will seek an operating system on one of the disks and then launch
and turn control over to the operating system.
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 briefly
at the bottom of the screen during the POST.
Press DEL to enter 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:
PRESS F2 TO CONTINUE, DEL TO ENTER SETUP
38
Page 39
4.3 Using Setup
In general, you use the arrow keys to highlight items, press <Enter> to
select, use the PageUp and PageDown keys to change entries, press <F1>
for help and press <Esc> to quit. The following table provides more detail
about how to navigate in the Setup program using the keyboard.

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.
40
Page 41
4.5 Main Menu

Change Supervisor Password
You can set either supervisor or user password, or both of them. The
differences between are:
Supervisor password: To enter and change the options of the setup
menus.
User password: To enter the setup menus only but do not have the right
to change the options. When you select this function, the following
message will appear at the center of the screen to assist you in creating a
password.
Enter Password
Type the password, up to eight characters in length, and press <Enter>.
The password typed now will clear any previously entered password from
CMOS memory. You will be asked to confirm the password. Type the
password again and press <Enter>. You may also press <Esc> to abort
the selection and not enter a password.
To disable a password, just press <Enter> when you are prompted to enter
the password. A message will confirm the password will be disabled.
Once the password is disabled, the system will boot and you can enter
Setup freely.
Password Disabled
When a password has been enabled, you will be prompted to enter it every
time you try to enter Setup. This prevents an unauthorized person from
changing any part of your system configuration. Additionally, when a
password is enabled, you can also require the BIOS to request a password
every time your system is rebooted. This would prevent unauthorized use
of your computer.
You determine when the password is required within the BIOS Features
Setup Menu and its Security option (see Section 3). If the Security option
is set to “Always”, password will be required both at boot and at entry to
Setup. If set to “Setup”, prompting only occurs when trying to enter
Setup.

Appendix A Watchdog Timer
The Watchdog Timer is provided to ensure that standalone systems can always
recover from catastrophic conditions that cause the CPU to crash. This condition
may have occurred by external EMI or a software bug. When the CPU stops
working correctly, hardware on the board will either perform a hardware reset (cold
boot) or a Non-Maskable Interrupt (NMI) to bring the system back to a known
state.
A BIOS function call (INT 15H) is used to control the Watchdog Timer:
INT 15H:
AH – 6FH
Sub-function:
AL–2: Set the Watchdog Timer’s period
BL: Time-out value (Its unit--second or minute, is
dependent on the item “Watchdog Timer unit select” in
CMOS setup).
You have to call sub-function 2 to set the time-out period of Watchdog Timer first.
If the time-out value is not zero, the Watchdog Timer will start counting down.
While the timer value reaches zero, the system will reset. To ensure that this
reset condition does not occur, Watchdog Timer must be periodically refreshed by
calling sub-function 2. However, Watchdog timer will be disabled if you set the
time-out value to be zero.
A tolerance of at least 10% must be maintained to avoid unknown routines within
the operating system (DOS), such as disk I/O that can be very time-consuming.
Note: When exiting a program it is necessary to disable Watchdog Timer,
otherwise the system will reset.

Appendix C How to Use Wake-Up Function
POS-478 provides two kinds of Wake up Function: Modem Wake-up and LAN
Wakeup.
Wake-Up function will be activated when ATX power supply is in use.
Wake –Up On Modem (Ring):
Enable Wake-Up On LAN/Ring of CMOS SETUP. ATX power supply will be switched
on when there is a ring signal detected on pin “RI” of serial port.
Wake-Up On LAN:
When your computer is in power-down status, LAN Link/Active LED will flash. This
status indicates that the LAN chip has entered standby mode and waits for
Wake-Up signal. You can use other computers to wake up your computer by
sending ID to it.
ID: ID is the address of your system LAN. Every LAN chip has a factory set ID,
which you can find it from network information in WINDOWS.
ID format is xxxxxxxxxxxx
Example ID: 009027388320

Appendix D Digital I/O
One of digital circuit’s characteristics is its fast response to high or low signal. This
kind of response is highly needed for harsh and critical industrial operating
environment. That is why we design 4-bit digital inputs and 4-bit digital outputs
on POS-478.
There are two kinds of signals (Input and Output) used by the Digital I/O function.
These signals are used to control external devices that need On/Off circuit or TTL
devices. When one of the signals has been selected, users can read or write data
to the system through the Digital I/O function.
Digital I/O Address = 201H

Appendix E Creating/Deleting SATA Raid Sets
Creating and deleting RAID sets is a function found in the BIOS. During boot-up,
the following message will appear, pausing for a few moments to allow the user to
choose what to do:
Press <CRTL-S> or F4 to enter RAID utility
An easy-to-use screen will appear with the following choices in the top left:
Create RAID Set
Delete RAID Set
Rebuild RAID Set
Resolve Conflicts
Below this will be listed the drives currently installed on the system.
The top right half of the screen displays directions and comments for the user.
The bottom right half lists the command keys:
Arrows up and down are Select Keys
ESC takes the user to the previous menu
Enter selects the user’s choice
Ctrl-E exits the utility
Creating RAID Sets
Because SATA Raid supports two drives, creating RAID Sets is a simple procedure.
1. Select “Create RAID Set.”
2. Choose either a “Striped” or “Mirrored” RAID Set.
3. Select if you want the utility to Auto Configure the RAID Set or if you want to
manually configure the RAID Set. For Striped Sets, you can change the chunk size.
For Mirrored Sets, you assign which is the Source and Target drives, as well as if
you want Disk Copy.
63
Page 64
What is Disk Copy? If the disk assigned as the source disk already has been
partitioned and has data stored on it, and then a second disk is added for
redundancy, the data on the source drive can be copied to the destination drive, so
the disks are identical, and all subsequent data will be written to both drives as a
Mirrored set. If, however, the source disk does n o t h a v e d a t a a l r e a dy st or e d o n i t ,
there is no need for Disk Copy.
The utility will ask, “Are You Sure?” before completing the configuration.
Deleting RAID Sets
1. To remove one or more RAID sets, select “Delete RAID Set.”
2. Select desired set and press Y when asked “Are You Sure?”
Resolving Conflict
When a RAID set is created, the metadata written to the disk includes drive
connection information (Primary Channel, Secondary Channel). If, after a disk
failure, the replacement disk was previously part of a RAID set (or used in another
system), it may have conflicting metadata, specifically in reference to the drive
connection information. If so, this will prohibit the RAID set from being either
created or rebuilt, In order for the RAID set to function properly, this old metadata
must be first overwritten with the new metadata. To resolve this, select “Resolve
Conflict” and the correct metadata, including the correct drive connection
information, will be written to the replacement disk.

Appendix F Connecting LCD to POS-478
POS-478 can support both one-channel and two-channel LVDS LCD through
connector J1. We use the LCD – LTM15C423S (2-channel) as an example to
explain the signal mapping and data format.
The pixel data of LTM15C423S is 48-bit wide. To use 36-bit LCD, neglect the third
pair of signals — (DATA3+, DATA3-). In other words, only the data of MSB (R2 ~
R7, G2 ~ G7, B2 ~ B7) will be left. On the other hand, if one- channel LCD is used,
only the first channel (CH1) is necessary. The way of dealing with 18-bit data is
the same as that of 36-bit (data of MSB are kept useful). For further information
on different types of LCD, refer to the datasheet.
