HP Dc7800 vPro Prerequisites and Trade-offs for the dc7800p Business PC with I - Page 6

At launch, HP Compaq dc7800p Business PC configurations will have a blank SOS partition. This partition is located at the end of the hard drive and is inaccessible. The main client operating system partition (COS) housing Windows XP or Vista is at the front of the hard drive, and the HP Backup and Recovery Manager partition is located behind the COS. Figure 1 HDD partition layout Customers who build their own images should be aware of the partition layout requirements for Intel vPro technology. The SOS partition must be exactly 102MB, be type 72h, not formatted, not enumerated, and located at the end of the hard drive. Network Changes Intel vPro technology requires usage of the embedded Intel 82566DM Network Interface Controller (NIC). After a Virtual Appliance is installed, PCI and PCI-e add-in NICs will no longer function. This is a security feature to prevent network traffic from add-in NICs bypassing the SOS. This may be a limitation for customers that require multiple NICs. However, USB NICs are not virtualized by the Intel LVMM, and therefore may circumvent installed Intel vPro processor technology compatible management and security appliances. For more details about network controller behavior, see the HP Compaq Business PCs with Intel vPro Processor Technology and Virtual Appliances white paper at www.hp.com. Memory Changes The management engine requires that memory is populated in channel A. If memory is not populated in channel A, the ME cannot function and all AMT or ASF features are lost. A POST error message displays if memory is not populated in channel A. If this occurs, power off and unplug the system so memory can be reconfigured. The POST error is as follows: 2211-Memory not configured correctly for proper MEBx execution. Make sure there is a memory module in the black DIMM socket. 6
