Yes, there was a multiprocessor HAL and a uniprocessor HAL. There were also variants of each for ACPI vs non-ACPI, as well as some weirder things. I'm not sure how many of those may have survived into Windows 7, but I am pretty sure a dual core Pentium and an i5 will both use the ACPI mutliprocessor HAL. -- Ben
