   Hello Patrik!

No, they don't show up in Boot Menu.

Sure, but the NSD docs don't list warpdrive.device as supported device nor
found I an evidence that it is supporting large disks in general.

However, it seems as if I don't need just pfs-aoi, but also some other parts of
 pfs. Hints are welcome! ;-)

Well, I got my 7720U for a good price as well, otherwise I would have opted for
 the ARS2000SUP, because of the SATA interface. Alas, I would have had the same
 issues with WarpEngine and PFS then, I think... ;)
