Dual CPU / Dual Core
If you have a PC with multiple physical CPUs that is, two or more chips installed on the motherboard
you'll need Windows Vista Business, Enterprise, or Ultimate to take advantage of both CPUs.
If you install Vista Home Basic or Home Premium, the OS will only recognize one CPU.
That's similar to the way Windows XP works today.
If have a dual-CPU machine, you need to install XP Professional to use both CPUs.
So what about dual-core CPUs?
That's different.
All Vista versions, even the lowly Home Basic,support multiple cores on a single chip,
with no additional configuration required.
To sum it up :
Multiple Cores should be seen on the Windows Vista Home Skus.
Two CPU sockets would require Windows Vista Business, Windows Vista
Enterprise or Windows Vista Ultimate to see the second physical processor.
