Hi everyone,

I imaged it with my domain image (XP) and it appears to be functioning as it should. However, I noticed that the task manager only displays, and only provides me with the option to display 1 CPU. When looking in the Device Manager/Processors, I see "2" seperate entries for Intel Core2 Duo CPU T17700 @ 2.40Ghz. I also see Advanced Configuration and Power Interface (ACPI) PC under Computer in Device Manager, but nothing that reads "Multiprocessor"

Any thoughts on how I might be able to allow the OS to offically see the second CPU?

Thanks and Happy Holidays,

Mike

When you have Task Manager open click on 'View' and choose 'CPU History' then select 'One Graph Per CPU'.

The 'Performance' TAB should now show one graph per core. - OR is that what you don't have an option to do ?

That is what I don't have an option to do. When I'm in Task Manager, and click View/CPU History, the only option I am presented with is "One Graph Per CPU"., so I only see 1 graph. "One Graph, ALl CPUs" is not present, so I don't see both CPUs

When you go into Task Manager View CPU History the two options that may be there are One Graph Per CPU or One Graph All CPU's.

If you have XP Home this [b]Doesn't Support[/b] Multi CPU Configuration. It was only designed to show 1 CPU and work properly with 1 Core.

If you have XP Pro it should show Multiple CPU's but this is one of the differences between XP Home & Pro.

Check the BIOS, there might be a setting that turns one CPU off, or allows the hardware to turn it off... Or there is a setting to disable the 2nd CPU.

I looked in there right before creating this post. No such luck. Thanks though, great suggestion!

service pack are you running? also, just to double check, are you running XP Pro or Home?

the only reason I would say that is when I was a Tech, we dealt with Dell Precision laptops/workstations, and the image installs with fat 32, so most of the time we had to put it in OS mode and limit the PC to 256 MB of ram, and turn off CPU's (rare occasion). just to get the OS installed... it was a total crap shoot install... plus it was the most butchered XP version I have ever scene (corp)....
