AMD x64 4400+ processor shows only one CPU in task manager-XP Home

[boathead]

Hello,
I have a dual boot setup on my machine . When I boot to XP Pro 64 bit
edition, in the task manager "performance" window I show 2 CPUs.
When I boot to XP Home Edition (Service Pack 2) it shows only 1 CPU(In
Device manager it shows 2 processors)!
I have seen a multitude of posts on this issue, but none really answer the
question of how to fix this problem. Can anyone tell me how to get Home
Edition to see both CPUs in task manager?

Open task manager..click the performance tab..click view..cpu history..one
graph per cpu and see if it helps.
