Thermal Solutions
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly crucial when building computer systems. Maintaining the proper thermal
environment is key to reliable, long-term system operation. The overall goal in providing the proper
thermal environment is keeping the processor below its specified maximum case temperature.
Heatsinks induce improved processor heat dissipation through increased surface area and
concentrated airflow from attached fans. In addition, interface materials allow effective transfers of
heat from the processor to the heatsink. For optimum heat transfer, Intel recommends the use of
thermal grease and mounting clips to attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below for collection of
heatsinks evaluated and recommended by Intel for use with Intel processors.

Chapter 3
Introducing BIOS
The BIOS is a program located on a Flash Memory on the motherboard. This program is a
bridge between motherboard and operating system. When you start the computer, the BIOS
program gain control. The BIOS first operates an auto-diagnostic test called POST (power on
self test) for all the necessary hardware, it detects the entire hardware device and configures
the parameters of the hardware synchronization. Only when these tasks are completed done it
gives up control of the computer to operating system (OS). Since the BIOS is the only
channel for hardware and software to communicate, it is the key factor for system stability,
and in ensuring that your system performance as its best.
In the BIOS Setup main menu of Figure 3-1, you can see several options. We will explain
these options step by step in the following pages of this chapter, but let us first see a short
description of the function keys you may use here:
•Press <Esc> to quit the BIOS Setup.
•Press ↑↓←→ (up, down, left, right) to choose, in the main menu, the option you want to
confirm or to modify.
•Press <F10> when you have completed the setup of BIOS parameters to save these
parameters and to exit the BIOS Setup menu.
•Press Page Up/Page Down or +/–keys when you want to modify the BIOS parameters for
the active option.
3-1 Entering Setup
Power on the computer and by pressing <Del> immediately allows you to enter Setup.
If the message disappears before your 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 <F1> to continue, <Ctrl-Alt-Esc> or <Del> to enter Setup
