We have a Dell Workstation 530, it has 2 processors. In device manager it shows 2 processors and the computer type is ACPI PC. In taskmanager under the performance tab it only shows 1 window, under the CPU history tab the only choice is 1 graph per CPU. I have tried to upgrade the driver for the computer in device manager, but I do not get a choice for multi processor ACPI PC. Is there an .INF file I can point to?

If you installed a UP (Uni-Processor) image on the MP (Multi-Processor) system, it would have the UP HAL. You can change the HAL to the MP by re-running sysprep, and in the sysprep.inf add an UpdateHAL command in the [unattended] section similar tobelow.

[Unattended]
UpdateHAL = "ACPIAPIC_MP, %WINDIR%\Inf.Hal.inf"

There are some limitations on the source systems, and target systems that an image can be moved to. If the source system was not APIC complaint, and you could only use the image on a non-APIC complaint target system, and you would replace ACPIAPIC_MP with MPS_MP in the previous example.

I'm assuming since you are taking about the device manager you are running W2K or XP. If it on an NT 4 system, you run the ResKit utilty UPTOMP.exe.

Did not work in this case, we had to reinstall XP over the existing installation and then it recognized the 2 cpu's. As a result we had to reinstall XP Service Pak 2. This may have not worked because of some entry in our Sysprep.inf ie.. the location of the i386 folder. So I think this might have worked if we had our stuff together. Thanks "mrandrewking"
