This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open This is an old article about SCO Unix and is only left here for historical purposes. There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.
First, hardware certification is by the makers of the hardware, so it is expected and natural that you won't necessarily see a whole bunch of certified hardware when a new release first comes out.
But a more important issue is this: if hardware is certified or otherwise known to work on version x where x is less than the current version, it is EXTREMELY unlikely that it would not work just as well with the current version. The reverse might not be true, but it's more than rare for a new version to deliberately or accidentally break compatibility with older hardware. ~
