Go: DeviceManager/Check what flavor of Hal*.dll XP installed:
ACPI Multiprocessor PC: Halmacpi.dll
ACPI Uniprocessor PC: Halaacpi.dll
Advanced Configuration and Power Interface (ACPI) PC: Halacpi.dll
MPS Multiprocessor PC: Halmps.dll
MPS Uniprocessor PC: Halapic.dll
Standard PC Hal.dll
If it is "Standard PC," it does not have the ACPI capabilities, obviously;
If your PC is ACPI, install the correct Hal*.dll file from your WXP CD - try
a Google search for "Hal.dll install"
Also, try this one fore more options:
