single core XP image, onto dual core computer

Hewlett-packard Microsoft windows server...

Specs: Windows xo, 1222
I have a WinXP image that was created from a computer running WinXP that had a single core processor (i believe a P3). The image was installed on a new computer that has a dual core processor, when i go to task manager it only shows 1 cpu, even after i choose '1 graph per cpu'.

does this mean the computer is only using 1 of the 2 processors?

Device manager also shows only 1 cpu.

Is this a problem? do i have to create a new image taken from a dual core computer, and then install this on the new dual core computers?

You do only have 1 cpu, but it has dual cores. If your image isn't working correctly, you'll have to do an xp repair installation so it picks up the new hardware.

Why are you using images and not doing a clean install of XP?

XP is very hardware specific and usually a transplanted operating system requires a repair install in order to function in the new hardware environment.

its only showing 1 core in the task manager. it is not showing 2.

This is how my employer has it setup to install XP onto new company computers!!

is this a problem using the image that is from a processor with a single core cpu onto a computer that has a dual core processor???

will this mean only 1 of the 2 cores will be used?

"will this mean only 1 of the 2 cores will be used?"

that would be correct since the HAL only knows of one processor

to get this straight. this might sound stupid but i want to understand it!!

the image is from a Single Core Processor

the new computer has a Dual Core Processor

'wanderer' wrote 'that would be correct since the HAL only knows of one processor'

does 'wanderer' mean HAL only knows of 1 core?? instead of saying 1 processor?

there is one processor in the computer, but it contains 2 cores.

One processor is one processor on a single die.
Dual core is two processors on a single die that are linked.

The hal is built during install. its how the OS talks to the hardware. For example back in the days of NT and SMP install would start on a single processor but then go to multiprocessor hal after the first reboot since the system detected multiple processors.

As stated previously a repair install should load the correct dual core hal. [then make a new image :-)]

ok thanks, i understand

but presently, is the Dual core computer only using 1 of its 2 cores??? until the repair install is performed?

is there any other way besides repair install, say using a file from an existing dual core setup and copy that over to the computer in question?
