Replacing or adding a processor

The system is compatible with the Pentium® III (FC-PGA Socket 370) 667 MHz and faster processors with 133 MHz front-side bus (FSB). As many as two processors may be installed in the system (they must have the same processor and FSB speed). Processor and FSB speed are automatically detected by the system, therefore there are no system board jumpers to set.

When adding or replacing a processor, order a processor upgrade kit from Gateway. The kit includes the processor, a heatsink, and a disposable, antistatic wriststrap. The kit also contains a copy of the muloader.exe program, which must be run to update the microcode table and enable the second processor. Voltage Regulator Modules (VRMs) for both processors are built into the system board.

Caution A heatsink must be installed on each processor. Installing a processor without a heatsink could result in damage to, or failure of, the processor.

To replace the processor you must perform the following tasks:

■Remove the heatsink

■Remove the processor

■Install the new processor

■Replace the heatsink

To remove the heatsink:

1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.

2Remove the left side cover panel. (See “Removing the side cover” on page 18 and “Preventing static electricity discharge” on page 15.)

3Disconnect the fan cable from the fan connector on the system board. (See “System board” on page 6 for the location of the fan connector.)
