Add X86S architecture info. 2. explains how virtual machine extensions work. 3. eliminated "ring -1" since it does not exist: "ring -1" is created as a easy-to-understand concept to explain how virtual machine extension controls permissions within ring 0. undo Tag: Visual edit

curprev 02:4702:47, 29 November 2023‎ Guy Harris talk contribs‎ 28,952 bytes −4‎ But, unfortunately, that's not an article about call gates in general, it's an article about call gates in x86. undo Tag: Manual revert
curprev 02:4402:44, 29 November 2023‎ Guy Harris talk contribs‎ 28,956 bytes +4‎ Undid revision 1187406711 by NasssaNser (talk) - who's "we"? Multics, the prototypical multi-ring OS, used call gates; just because the multi-ring model isn't being used much today, with the supervisor vs. user mode model being predominant, that doesn't mean call gates are of no interest. undo Tags: Undo Reverted

curprev 20:4920:49, 12 June 2023‎ Guy Harris talk contribs‎ 28,951 bytes −9‎ The GE 645 (and, if you insist on machines with full ring support in hardware, the Honeywell 6180) didn't have a motherboard, and if there were "chips" rather than individual transistors in the 6180,, they were probably SSI at best. Speak, instead, of "I/O controllers", which should be vague and general enough to cover all sorts of computers. undo
