Secure the heatsink to the system board and system board tray with the 4 captive screws and attach the heatsink control cable to the system board. CAUTION: Heatsink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly seat the heatsink on the processor.

NOTE: After installing a new processor onto the system board, always update the system ROM to ensure that the latest version of the BIOS is being used on the computer. The latest system BIOS can be found on the Web at: http://h18000.www1.hp.com/support/files. Speaker 1. Prepare the computer for disassembly (Preparation for Disassembly on page 60). 2.
