Important VMware ESX considerations: When installing and running VMware ESX on
this server, the operating system might fail to install or boot with the following error

 One processor is installed and no mezzanine board is installed.
 Two processors are installed and matching memory is installed on both the system
board and the mezzanine board.
 Two processors are installed, no internal memory is installed, and the memory installed
in an attached MAX5 memory expansion is configured as non-pooled memory.
