Not "errata". 286 had more address space, so above 1MB didn't wrap around (by design). But this differed from 8086.

- hakfoo 3y agoI thought the idea was that in real mode it should be have like a faster 8086, and exposing memory beyond 1Mb breaks the illusion.
- mlyle 3y agoIt does break the illusion. At the same time, it allowed another ~64k of memory, which was important. DOS eventually sat up there in the non-wrapped memory. So, feature or bug? Heh.
