BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/
Ouput System).
Your computer is already configured and optimized properly, and you do not need to run this utility.  However, 
if you encounter configuration problems, you may need to run it.  
To activate the BIOS Setup Utility, press F2
 during POST while the TravelMate logo is being displayed.
Navigating the BIOS Setup Utility
There are six menu options: System Information, Basic System Settings, Startup Configuration, Onboard 
Device Configuration, System Security and Load Default Settings. 
To enter a menu, highlight the item using the 
­ ¯ keys; then press Enter
.
Within a menu, navigate through the BIOS Setup Utility by following these instructions:

Press the cursor up/down keys (
­¯) to move between parameters.

Press the cursor left/right keys (®
¬) to change the value of a parameter.

Press Esc
 while you are in any of the menu options to return to the main menu
NOTE: 
You can change the value of a parameter if it is enclosed in square brackets. 
NOTE: 
Navigation keys for a particular menu are shown at the bottom of the screen.

System Information
The System Information screen displays a summary of your computer hardware information.
The table below describes the parameters in this screen.    
Serial Number
The Serial Number is the number identical to the system serial number labelled at the bottom of system unit.  
The default Serial Number is scanned while manufacturing and stored to the LCD inverter.
  While service 
engineers swapping invertors for customers, they should re-input the original Serial Number to the system.  Or 
this field in BIOS Setup will be in blank.  To change the Serial Number field, please refer to “System Utility 
Diskette” in chapter 2 for more information .   
Asset Tag Number
The default setting is empty.   Customers can input into the Notebook Manager (setting by themselve whatever 
the number they need but only can input once).  While service engineers swapping inverters
 for customers, 
customers can re-input. 
ParameterDescription
CPU Type & Speed Describes the type of CPU installed in the system.
Floppy Disk Drive  Shows the floppy disk drive type (1.44MB 3.5-inch).
Hard Disk (MB) Sets the hard disk type.
HDD Serial Number Shows the hard disk drive serial number.
System with Shows the high-capacity disc drive installed.
System BIOS Version Shows the system BIOS version.
VGA BIOS Version Shows the video graphics accelerator BIOS version.
Serial Number Shows the serial number of the system.
Asset Tag Number Shows the asset tag number.
Product Name Shows the official name of the product.
Manufacturer Name Shows the name of the manufacturer.
UUID Shows the universally unique identifier number.

							Chapter 129
Product Name
It is the default setting as the brand name + model name of Acer product;  such as TravelMate 505.   Product 
Name will be automatically created by using 505Util.zip
.
Manufacture Name
The default setting is Acer.   Manufacture Name will be automatically generated by using 505Util.zip
.
 
UUID
It stands for  Universally Unique IDentifiers, also known as GUID (Globally Unique IDentifier).   The 
requirement specification of SMBIOS 2.1
 (System Management BIOS).   UUID are fixed-size 128-bit value 
and are unique across both space and time.  The currently-used algorithm that was created by the OSF (Open 
Software Foundation) from a combination of a timestamp, physical Ethernet address, and a sequence number 
to generate the unique ID number until the year A.D. 3400
.   Without a network card machine, a different 
method is used to generate that part of the GUID.   It differs from Intel number which identifies a computer, but 
UUID number can identify a person and even confidential documents user created.    
        To automatically generate a UUID , please refer to “System Utility Diskette” in chapter 2 for more 
information .   
 
NOTE: 
The Serial Number, Asset Tag Number, Product Name, Manufacture Name and UUID  are 
located in the LCD inverter.
