Yes and

The reason is that IAA is essentially a software package that emulates a larger address space. there were similar programs around in the '90ies like dynamic disk overlay and all that stuff that never really worked but IAA does actually work quite well, now that they have versions that also run on single drive configurations. Originally IAA was made as a tool to enable RAID configurations and that is where the issue first surfaced -- there was no way of addressing these "drives" anymore in a 32-bit address space -- and one good thing about Intel is that if there is a problem, they usually find a way to work around it.

Took a few years to come out whith a version that runs on single drives, though
