I don't think this is accurate. Xenix pre-existed the 386 and was used on other processors before and after it supported the 386.
Since I thought maybe I was going crazy, I checked Wikipedia and read, for example, "Version 2.0 of Xenix was released in 1985 and was based on UNIX System V. An update numbered 2.1.1 added support for the Intel 80286 processor"
- yuhong 13y agoI know. I am talking in the sense that its 386 port predated other 386 OSes.
- seanmcdirmid 13y agoCouldn't Xenix run even on an 8086? I don't think it required an MMU at all.
- kjs3 13y agoThere were successive Xenix versions for 8086, 80286 and 80386.
