CHAPTER 1
GETTING STARTED
This chapter describes how to unpack and identifying components on the device. The following topics are
described.
• Unpacking the machine on page 1
• Identifying components on page 2
Unpacking the machine
It is a good idea to save the packaging materials and shipping box in case that machine needs to be returned
for service. Please un-pack and re-pack the machine terminal as shown in Figure 1.1.

CHAPTER 2
BIOS SETUP
The primary function of the BIOS (Basic Input and Output System) is to identify and initiate component
hardware. The BIOS parameters are stored in non-volatile BIOS memory (CMOS). CMOS contents don’t get
erased when the computer is turned off. The following topics are described in this chapter.
• About the Setup Utility on page 5
• Main Screen on page 8
• Advanced Settings on page 9
• Boot Settings Conguration on page 18
• Chipset Settings on page 22
• Security Settings on page 25
• Exit Menu on page 26
About the Setup Utility
The BIOS Setup Utility enables you to congure the following items:
• Hard drives, diskette drives, and peripherals
• Video display type and display options
• Password protection from unauthorized use
• Power management features
This Setup Utility should be used for the following:
• When changing the system conguration
• When a conguration error is detected and you are prompted to make changes to the Setup Utility
• When trying to resolve IRQ conicts
• When making changes to the Power Management conguration
• When changing the User or Supervisor password

6 CHAPTER 2 BIOS SETUP
Entering the Setup Utility
When you power on the system, BIOS enters the Power-On Self Test (POST) routines. POST is a series of
built-in diagnostics performed by the BIOS. After the POST routines are completed, the following message
appears:
Press DEL to run Setup
Press the delete key <Delete> to access the BIOS Setup Utility:
BIOS navigation keys
The BIOS navigation keys are listed below.
Key Function
← → Select screens
↑ ↓ Select items
+ – Modies the selected eld’s values
Enter Go to sub screen
F1 Displays a screen that describes all key functions
F10 Saves the current conguration and exits Setup
Esc Exits the current screen
Figure 2.1 Main BIOS screen

Using BIOS
When you start the Setup Utility, the main screen appears. The main screen of the Setup Utility displays a list
of the options that are available. A highlight indicates which option is currently selected. Use the cursor arrow
keys to move the highlight to other options. When an option is highlighted, execute the option by pressing
<Enter>.
Some options lead to pop-up dialog boxes that prompt you to verify that you wish to execute that option.
Other options lead to dialog boxes that prompt you for information.
Some options (marked with a triangle ►) lead to sub screens that enable you to change the values for the
option. Use the cursor arrow keys to scroll through the items in the sub screen.

8 CHAPTER 2 BIOS SETUP
Main Screen
This screen includes System BIOS Information, Processor, System memory and displays the System Time
and System Date.
System Overview
This screen displays System BIOS Information, Processor, System memory, System Time and System Date.
System Time/ System Date
The System Time and System Date items show the current date and time held by the machine. If you are
running a Windows OS, these items are automatically updated whenever you make changes to the Windows
Time and Date Properties utility.
Figure 2.2 Main Screen

Advanced Settings
This setup screen includes sub-menus for IDE Conguration, USB Conguration, ACPI Congurations, MPS
Congurations, Super IO Congurations and Hardware Health Conguration.
Spread Spectrum
When the motherboard clock generator pulses, the extreme values (spikes) of the pulses creates EMI
(Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the
pulses so that the spikes of the pulses are reduced to atter curves. If you do not have any EMI problem, leave
the setting at Disabled for optimal system stability and performance.
Onboard LAN Boot ROM
This feature allows users to enable or disable the onboard Lan boot ROM to boot system.

IDE Conguration
Hard Disk Write Protect
This item will be effective only if the device is accessed through BIOS.
Figure 2.4 IDE
Conguration sub-menu

11
Primary/ Secondary IDE Master
Type
Select [Auto] to automatically detect hard disk drive. If auto detection is successful, the BIOS Setup
automatically lls in the correct values for the remaining elds on this sub-menu. If the auto detection fails, it
may due to that the hard disk is too old or too new. If the hard disk was already formatted on an older system,
the BIOS Setup may detect incorrect parameters. In these cases, select [User] to manually enter the IDE hard
disk drive parameters.
LBA/Large Mode
This allows user to select the LBA/Large mode for a hard disk > 512 MB under DOS and Windows; for
Netware and UNIX user, select [Off] to disable the LBA/Large mode.
Block (Multi-Sector Transfer)
Set this item to [On] will enhance hard disk performance by reading or writing more data during each transfer.
PIO Mode
This item is used to select the IDE PIO (Programmable I/O) mode program timing cycles between the IDE
drive and the programmable IDE controller. As the PIO mode increases, the cycle time decreases.
DMA Mode
This allows user to select the Direct Memory Access (DMA) mode.
S.M.A.R.T.
This item is used to enable monitoring of hard disks that support the S.M.A.R.T. (Self-Monitoring And
Reporting Technology) feature, which can allow the hard disk to report, under some circumstances,
impending failures of the hard disk.
32Bit Data Transfer
It allows user to enable 32-bit access to maximize the IDE hard disk data transfer rate.

12 CHAPTER 2 BIOS SETUP
CPU Conguration
Max CPUID Value Limit
When enabled, the processor will limit the maximum CPUID input value to 03h when queried, even if the
processor supports a higher CPUID input value. When disabled, the processor will return the actual maximum
CPUID input value of the processor when queried.
Execute-Disable Bit Capability
This feature is used to protect certain system memory data regions from insertion and execution of potentially
harmful code.
Hyper Threading Technology
This feature allows a single processor to execute two or more separate threads concurrently. When hyper-
threading is enabled, multi-threaded software applications can execute their threads in parallel, thereby
improving their performance.
