Activating the Integrated NIC TOE

To add TCP/IP Offload Engine (TOE) functionality to the system's integrated NIC, install the TOE
NIC hardware key in the TOE_KEY socket on the system board (see Figure 6-2). For TOE software
installation instructions, refer to the documentation that came with your TOE NIC hardware key.

Microprocessor

You can upgrade the system processor(s) to take advantage of future options in speed and functionality,
or add a second processor. Each processor and its associated internal cache memory are contained in a
land grid array (LGA) package that is installed in a ZIF socket on the system board.
