MP978
Intel P55C 166~233Mhz,  Intel Tillamook 233~266Mhz, AMD K6 Mobile 266~300Mhz, AMD K6-2 266~333

  • Intel only produces Tillamook CPUs in TCP packaging which means that they must be soldered to a circuit board.  We have soldered the Tillamook to a daughter board which plugs into the socket on the mainboard, these CPU's are no longer available. Tillamook also requires an additional voltage regulator board to supply the 1.8v to the Tillamook.
  • AMD K6 300Mhz requires the 3rd digit of the serial number to be "H" or higher and also requires an additional voltage regulator board which must be purchased from Keydata
  • AMD K6-2 will only work on systems with mainboard revision AI01/R6A or AI01/R7A. The main board revision sticker is located under the palm rest on the internal modem connector or on the memory sockets.

MP979
Intel Mobile Pentium II 233~333Mhz in Mobile Module 1 (MMC-1) package. 

  • Note that inserting / removing a mobile module package requires specialized tools and should not be done by any other means.
  • Be sure to remove the battery and AC power from the computer before inserting or removing a mobile module.  The MMC1 socket will have power present even with the system power off.  Inserting or Removing a CPU with power present can easily damage the CPU and mainboard.

Location
The microprocessor is located under a door on the bottom of the computer

Installation

  • Turn off the computer and remove all power sources
  • Turn the computer over and position it so that the ports on the rear of the computer are away from you.
  • In the rear right side there will be a door with fan vents cut into it.  Remove the 2 screws retaining this door then remove the door.
  • Under the door you will find a heat sink/fan assembly.  To the right of the fan there is a small duct.  In the center of the duct there is a hole which is covered by tape.   Peel back the tape and remove the screw underneath.  Just to the other side of the fan there is one more screw.  Remove the second screw and lift the heat sink/fan assemble off of the CPU. 
  • You will see the CPU which sits in a socket.  On either side of the CPU there are 2 tabs, the left one is label OPEN and the right one will be covered by a black plastic lock clip.  Remove the lock clip from the right side.
  • Insert the tip of a flat screwdriver into the side labeled OPEN and move the handle towards the LOCK side.  This will create leverage and slide the CPU to the left slightly.  Remove the CPU, it should come out easily.  If you encounter resistance, you do not have the socket unlocked completely.
  • Install the voltage regulator board.  This step only applies if you are installing a Tillamook or AMD K6 300Mhz (not required for 266) CPU. Remove the 2 jumpers from the header between the CPU socket and the rear of the computer, and install the voltage regulator board on to the headers.  The board is keyed so you cannot install it backwards.
  • Set the switches according to the table below to configure CPU type, speed, and voltage.
  • Insert the new CPU into the socket.  Place the tip of a flat screwdriver into the side of the socket labeled LOCK.  Move the handle of the screwdriver towards the OPEN side.  The chip and socket must move until the socket touches the tab the OPEN is printed on.
  • Insert the lock clip into the LOCK side of the socket.  This clip should snap into place.  It should not be able to fall out on its own.  If it does not snap into place, the socket is not locked all the way. Repeat the last step and be sure the socket moves all the way until it touches the tab that OPEN is printed on.
  • Install the heatsink/fan and the door.

MP979
The MP979 uses a mobile module CPU.  This CPU requires a special insertion / removal tool.  You should not attempt to remove or install the mobile module without this tool or damage to the CPU and mainboard may occur.

  • Remove all power sources from the computer.
  • Turn the computer over, remove the 2 screws from the CPU door (has fan vents in it), and remove the door
  • Remove the 2 screws from the heat sink and remove the heat sink
  • Remove the 3 screws holding the mobile module in place.
  • Use the extraction tool to remove the CPU
  • Use the Insertion tool to install the new CPU.
  • Reinstall the CPU screws, the heat sink and screws, and the CPU door and screws

 

CPU clock speed for Intel (P55C MMX & Tillamook):

CPU speed SW1:2 SW1:3 SW1:4 SW1:5
100 MHz OFF OFF OFF OFF
120 MHz ON OFF ON OFF
133 MHz OFF OFF ON OFF
150 MHz ON ON ON OFF
166 MHz OFF ON ON OFF
200 MHz OFF ON OFF OFF
233 MHz OFF OFF OFF OFF
266 MHz OFF ON ON ON

CPU clock speed for AMD K6:

CPU speed SW1:2 SW1:3 SW1:4 SW1:5
233 MHz OFF OFF OFF OFF
266 MHz OFF OFF ON ON
300 MHz OFF ON ON ON

The AMD K6 requires the 3rd character of the serial number to be "H" or higher.  The K6 300 requires an additional voltage regulator board which must be purchased from Keydata.  AMD K6-2 requires specific mainboard versions (see text above) DO NOT install a K6-2 without the proper mainboard version or damage to the CPU and mainboard will occur.
