Windows XP HOME and Dual-core X60s

[supportsquakmt]

I ordered a dual-core X60s with Windows XP Home.
It's cheaper than XP Pro, which I don't need on this machine.

XP Home says it only supports one CPU

So, am I going to see only one of the dual cores on this machine ?

Here's the build, FYI...

I think you will see both CPU's. I used a Pentium 4 with Hyper Threading running on XP home and it saw both cores. I think that was fixed with Service Pack 2, since dual core computers were coming into the consumer market. Lenovo would not offer XP home if it was not going work properly with their hardware.

The new xp home has dual core enable. I think MS changed the specifications of the old xp home in sp2. btw there are 2 core files if i am not wrong in the xp pro folder that can be imported into any windows to enable a system to be dual core without a reformat.

hope this helps,

windows xp home will use both cores. ms licenses the software per socket - not cores.

(my housemate's t60 with windows xp home seems to be functioning with both cores)

I'm curious to see what happens when the quad cores come out and to take that even further when quad cores are used on dual processor boards for a total of 8. Is the OS going to cost even more to support more than the allowed 2 processors ?

hmm that is a good question.

As Tian said, the OS is licensed per physical CPU, not per core. Windows XP Home will run with one physical CPU, whether single, dual or quad core -- but it will not use multiple physical CPUs.
