3.3.7Boot ROM

The system boot ROM is installed on the Intel 82802AC FWH device. The FWH is addressable on the LPC bus off the Intel® 6300ESB ICH.

3.3.8In-Target Probe (ITP)

The evaluation board contains an in-target probe (ITP) connector for an ITP-XDP connector. You must use an ITPFlex specific to the Dual-Core Intel Xeon processor LV. Other ITPs will not work and if installed, could damage the platform and/or the ITP. Figure 15 shows the ITP connector which is located between the DIMM B4 connector and the edge of the board. For more information refer to ITP700 Debug Port Design Guide (http://www.intel.com/design/Xeon/guides/249679.htm).
