1	The numbers in this line reflect the maximum hardware configuration of current Server Units. VM2000 can manage up to 64 real CPUs. The number of real CPUs for VM2000 operation is further restricted by the BS2000 model installed.
2	Defined by the firmware and the VM2000 implementation. Further restricted by the BS2000 model installed.
3	VM2000 can manage up to 99 VMs.
4	From the startup parameter file, only the VM2000 parameter VERSION is analyzed.
