Certainly those, but I think there are many boxen "behind the scenes", for loose definitions of "embedded" something like kiosks, et al., that are running necessary functions that nobody but installers and maintenance techs ever sees or thinks about. In '98 or so I pulled into my usual gas station for a fillup, and one of the pumps had it's cover off. I immediately recognized a 40-pin DIP on the board and had to take a look. It was a 1976 vintage Zilog Z-80 running the gas pump. Computers have snuck in everywhere! > Gentoo writes: "... Currently, the KPTI patch-set is only available for > 64-bit Gentoo operating systems.

In my investigation I too saw the 4GB/4GB split mentioned but with something else that caused me to disregard it--it had been pulled or something. I have 4GB in my "everyday" Conroes, though the refurb box I dedicate to W10 so's it can run TurboTax is only 2GB, IIRC. IMO, running a 64-bit OS is a plus only if it has more than 4GB to play with. -- Paul Rogers [email protected] Rogers' Second Law: "Everything you do communicates."
