Windows XP professional ACPI error

When installing Windows XP professional,i get a BSOD.The STOP code is A5 and the parameter 1 ends with a 3.According to microsoft,

https://support.microsoft.com/en-us/kb/314830

"This error is defined as "ACPI failed must succeed method." This error occurs if ACPI cannot build a control method to reference the ACPI namespace. Other arguments for this error reference the ACPI object that was being run and the name of the control method. One greatly simplified explanation (which might not be completely accurate) is that the system cannot find a way to get to the ACPI tables that define the Plug and Play and Power Management capabilities of the system."

Thats what the BSOD means.I have SATA drivers.I have partition setup and everything.When pressing f5 AND f7,it leads me to a type scren.There are 3 options,APCI uniproceseser,APCImultiprocesser and Other.

MacBook Pro, Windows 8

NVRAM is where Bootcamp saves process states for Windows installation because it needs to maintain state across reboots. SMC Reset is just cleaning up power states, audio db and and some other states (see them in the SMC Reset article).

Can you download W7 drivers from Apple servers manually and run setup.exe from Bootcamp folder? It should repair drivers.

I have a working version of Windows 7,so this is not needed (for now).But if i come across this situation again,I will restart the thread.Let it die out,but i will revive it when needed.
