Can anything general be said about the compatibility of today's crop of motherboards (ASUS is what I have in mind) with respect to older versions of Windows, like XP, or 7? I presume versions 8.1 or 10 should be expected to work, but what about drivers compatible with the older OS versions? POS Ready XP is supported until 2019, but will POS ready users be able to replace hardware in the interim?
