ID: Q238891

Microsoft Windows NT Server, Enterprise Edition version 4.0

The Windows NT 4.0 kernel currently contains two restrictions that limit the kernel's use to certain processors:

A check for a Pentium processor that was never released.

A processor bit configuration that limits the maximum processor family to seven.

Both of these checking routines are disabled when you apply Microsoft Windows NT 4.0 Service Pack 6, so Windows NT 4.0 can easily support future processors.

This behavior is related to the processing of the data returned by the KiSetProcessorType() function in the Windows NT 4.0 kernel for Intel-based computers.
