Known Limitations

•
Intel vPro technology currently supports only a single VA. You will need to select the right VA to suit
your needs.
•
VA 2.6 is available at time of launch of the HP Compaq dc7800p Business PC but will only support
Windows XP as the COS. There is no Vista support for VA 2.6.
•
VAs do not support RAID configurations at this time.
•
VAs do not support more than two processor cores at this time. Therefore, quad core processors such
as the Intel Q6xxx are not supported.
•
VAs do not support AMT 1.0. The system must be in AMT 2.x or AMT 3.0 mode.
•
VAs do not support any other network cards besides the onboard Intel 82566DM network controller.
•
Installation of a VA to a system with multiple hard drives might encounter complications. This is due to
the Windows XP plug n' play (PnP) algorithms using an in-place reorder mechanism for PnP enumera-
tion.
More details on this issue can be found in the Microsoft Knowledge Base Article at:
port.microsoft.com/kb/825668/en-us
To work around this issue, the IDE-R controller in Device Manager must be disabled and the system reboo-
ted before installing the VA. Once this is done, Windows XP will only see one IDE controller and enumer-
ate the hard drives properly. The IDE-R controller appears as a standard dual channel PCI IDE controller.
