Customer wanted to deploy Windows XP 32bit on a HP Z420 machine.
For this machine is a driver pack. I imported this driver in to MDT.
After deploying I had a unknown device – ACPI/ACPI0004/CPUSCK0
I could not find any driver. The windows device manager show still “unknown device”.
Under: Advanced –> Bus Options you will find the setting “Legacy ACPI CPU Tables”
This settings is default disabled. Enable it en unknown device is gone!!
