286 protected mode supports paging, but it can't revert to real mode and it only supports 16 MiB of RAM. And 286 PE is really buggy and limited. It's pretty crap.

386 support was dropped, 486 support has not yet been dropped as of writing.

286 doesn't support paging, only segmentation. I have read the manuals extensively, and also discovered what may be the last undocumented feature, almost 40 years after the chip being released. [https://rep-lodsb.mataroa.blog/blog/intel-286-secrets-ice-mo...]

Not saying this to brag, just to establish that I probably know more about that chip than the average poster. And you're also posting plainly wrong claims elsewhere in this thread. I don't get why you're doing this?
