0.6 STATIC ELECTRICITY PRECAUTIONS
Before removing the board from its anti-static bag, read this section about static electricity precautions.
Static electricity is a constant danger to computer systems. The charge that can build up in your body may be
more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic
precautions whenever you use or handle computer components. Although areas with humid climates are much
less prone to static build-up, it is always best to safeguard against accidents that may result in expensive repairs.
The following measures should be sufficient to protect your equipment from static discharge:
Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded
wrist strap).
When unpacking and handling the board or other system components, place all materials on an anti-static
surface.
Be careful not to touch the components on the board, especially the “golden finger” connectors on the
bottom of the board.

2. INSTALLATION
This chapter describes how to install the AR-B1790. At first, the layout of AR-B1790 is shown, and the unpacking
information that you should be careful is described. The jumpers and switches setting for the AR-B1790’s
configuration are as below.

2.2 CPU INSTALLATION
This main board supports Intel Pentium 4/Celeron, Socket 478 series CPU. Please follow the step as below:
Be careful of CPU orientation when you plug it into CPU socket.
Pull up the CPU socket lever and up to 90°
Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU upper interface. Match Pin 1 and
cut edge, then insert into the CPU socket.
AR-B1790 User’s Guide
10
Press down the CPU socket lever and finish CPU installation.
The Intel Pentium 4/Celeron processor requires a set of heatsink/fan to ensure proper cooling of processor. If
heatsink/fan have not been already bundled with your CPU, you must purchase the heatsink/fan separately and
have it installed. Plug the cable through the heatsink/fan in the CPU fan power connector located nearby. Note that
there are seceral types of CPU fan connector. Normally, if your main board supports the hard ware monitoring
function, a 3-pin fan power connector should allow your system to detect the CPU fan’s speed.
2.3 CLEAR CMOS (JP6)
If want to clear the CMOS Setup (for example when you forgot the password, please clear the setup and then set
the password again.), you should close the pin 2-3 about 3 seconds, then open again, set back to normal
operation mode, close the pin 1-2.

2.4 INSTALL DDR SDRAM SYSTEM MEMORY
To install memory, insert DDR SDRAM memory module(s) in DIMM slot(s), Note that DDR SDRAM module are
directional and will not go in the DIMM slot unless properly oriented. After the module is fully inserted into the
DIMM slot, lift the chips of both sides of the DIMM slot to lock the module in place.
