Chapter 1 Motherboard 7KM400MN
The motherboard supports a maximized 3GB memory. It pro-
vides three 184-pin unbuffered DDR sockets and each supports
64MBto1GBDDRmemorymodule.
1.6.DDR SDRAM Installation
The motherboard operates with Socket 462 for AMD AthlonTM
and DuronTM processor. The CPU should always have a Heat Sink
and cooling fan attached to prevent overheating.
CPU Installation Procedures for Socket 462
1. Pull the lever sideways away from the socket then raise the
lever to a 90-degree angle.
2. Locate Pin 1 in the socket and look for the white dot or cut edge
in the CPU. Match Pin 1 with the white dot/cut edge then
insert the CPU.
3. Press the lever down to complete the installation.

Chapter 2 7KM400MNDrivers & Utilities
There are motherboard drivers and utilities included in
the disc attached in this motherboard package. You don't
have to install all of them for booting your system. But after
you have finished the hardware installation, you have to in-
stall an operation system (such as windows XP) before you
are able to install any drivers or utilities.
You can use the auto-run menu in the driver CD attached in
the motherboard package. Then choose the utility or driver and
select model name. The autorun starting screen looks like below:
