| The set of pins that my screwdriver is pointing at is the header for
making various chassis connections. For example the power on/off switch
connects here and the hard drive led (hd led) is connected here as well
as the reset switch. These are known as momentary switches because
the effect is to briefly close a circuit. |
 |
| This picture shows where we will plug in the wire that feeds power to
the processor' s built-in fan. The wire only fits one way. (click

 |
Here we point out where on the Intel D815EEAA we will be connecting
the small wire that is used to feed the audio signal from the CD ROM to
the Mainboard.

| Here we identify the quarter shaped battery that keeps the clock on
your system running as well it maintains power to the cmos
(complementary metal oxide semiconductor) chip. The cmos is responsible
for holding all the specific BIOS (basic input output system) settings
for your computer. A typical BIOS setting would be size and type
of hard drive, serial/parallel ports, processor speed etc. |
 |
| Here is the Processor chip we will use with our Intel D815EEAA
mainboard. It is an Intel Pentium III processor 800Mhz. |
 |
| The contents of the boxed processor. We identify the actual chip and
the separate Heat sink/fan. The plastic bag has some minimal
instructions and most importantly the Intel Inside logo sticker. You may
need to hunt a little for it. |
 |
| Before we can install the processor, we need to lift this little
lever, it unlocks the pin holes. |
 |
| Ok, now comes the tricky part. We need to make sure that the processor
is correctly orientated with the FCPGA socket. By examining the pins of
the processor you will note that two sides are not completely square, we
will call these notches. These notches need to line up with similar
notches on the socket. If the processor doesn't slip in easily to the
socket DON'T TRY TO FORCE IT. Trying to straighten out the hundreds of
pins on the chip is nearly impossible. Check and recheck that you have
the chip oriented the right way. |
 |
| Here we show the chip installed into the socket. The inset picture
shows the identifying mark that Intel has placed on the corner of the
chip to show the right orientation. |
