NT4 KeQueryActiveProcessors equivalence?

NTDEV

Hi All,
I use the KeQueryActiveProcessors() and CPUID instruction to calculate the
physical
active CPU numbers in system, but on NT4 this API doesn’t exists.
Does anyone know the equivalent API for KeQueryActiveProcessors() on NT4?
Or other ways to get the physical CPU numbers on NT4?
thanks.
