"on a test machine i did the following:I copied the three files (halmacpi.dll, ntkrnlmp.exe, and ntkrpamp.exe) from C:\WINDOWS\Driver Cache\i386\sp3.cab to c:\windows\system32, renaming them to hal.dll, ntoskrnl.exe, and ntkrnlpa.exe... respectively.After a reboot I could install the filter driver without problems.For the SCCM task sequences we a made script that sets the HAL to multiprocessor ACPI. But I had no time to test the script yet."
