System Memory Configuration
This 82440FX motherboard supports 72-pin SIMMs and 168
pin DIMM of 4MB, 8MB, 16MB, or 32MB to form a memory
size between 8MB to 384MB. Each bank must have 2 pcs of
DRAM modules (w/i same size and type) installed.
82440FX chipsets provide ÒTable-FreeÓ function. It means
that users can install DRAM with any configuration and in
any bank, and that is why the DRAM table is not needed.

CPU Installation
Follow the following steps in order to install your Intel
Pentium II (Klamath) properly.
Step 1:
Be sure you are in contact with heat sink vendors for
attaching the heat sink on to the CPU.

Notice that the heat sink may be different from the drawings
shown here.
Step 2:
Install the 2 pairs of screws, which are shown in the
following drawing, onto the mainboard under the word
KLAMATH.
Two of the screws are right around the word of KLAMATH
and the other pair of screws should be inserted opposite the
first pair.
