Starting the Installation
 |
First
item of business, pull the PCB you want to modify out of the cab. |
 |
Take
the cover off. |
 |
If
you have a 4 or 6 slot board, CAREFULLY seperate the two halves. You
will need to remove a couple of screws and bolts. Make sure you have
them all out before trying to pull it apart. |
 |
Locate
the BIOS chip. It should be socketed. If it is not....you are on your
own. I would not mess with a surface mounted chip myself. |
 |
!!!CAREFULLY!!!
pry the chip out of the socket. Go slow. Start at one side and gently
push a flat bladed screwdriver under the chip. Twist it slightly to
lift the chip. Do the same on the other side. Don't rush or you will
crack it. |
 |
Put
the new chip in it's place. Line up the small notch on the chip with
the notch mark on the PCB. Be sure to line up all the pins, and push
it in gently. |
 |
Following
Jeff's instructions, solder one end of each of the other two wires
to the resistors (one wire per resistor). Jeff makes it easy to do
as he has prepared a spot for you to solder to. Next,solder the end
of the third wire to the 11th pin on the bottom of the BIOS chip.
This is a ground, and it is the black wire in this picture. I try
to keep all the grounds Black or Green. This one is a bit trickier.
Take your time. |
