  • Page 33: Installing Upgrade Cpus

    G586VPM Installing Upgrade CPUs The G586VPM is equipped with two 320-pin Zero Insertion Force (ZIF) sockets at locations U5 and U10 of the system board. These sockets enable you to remove the old CPU and insert the upgrade CPU easily. If you need to apply excessive force to insert the CPU, the installation is being done incorrectly.
  • Page 34 PCI/ISA System Board Clearance Requirements The Pentium processor comes with a heat sink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the processor and heat sink require certain space clearances. The clearance above the processor’ s fan/heat-sink must be at least 0.4 in.
  • Page 35 G586VPM To install an upgrade CPU in the G586VPM, follow the steps below. 1. Make sure the handle on the side of the ZIF socket is up. To raise the handle, pull it out to the side a little and raise it as far as it will go. The top plate will slide back.
  • Page 36 PCI/ISA System Board Pin 1 of the ZIF Socket 3. Position the CPU above the ZIF socket. Make sure pin 1 of the CPU is aligned with pin 1 of the socket. Lower the chip until the pins are inserted properly in their corresponding holes.
  • Page 37 G586VPM Positioning the CPU Above the ZIF Socket 4. Push the handle down until the handle locks into its place. Top plate will slide forward. You will feel some resistance as the pressure starts to secure the CPU in the socket. This is normal and will not damage the CPU.
