I'm sure it's too late to ward off the flame war, but I'll try.
The 80386 is arguably a linear-addressed chip, in native mode. It has
pages, and the segments can be made large enough to be invisible. Perhaps
the segments can even be turned off, I don't remember.
But this split won't work. Some CPUs are neither segmented nor linear, or
they're both. I could see a small amount of merit in {paged,swapped}, but
even there the distinction blurs on some CPUs.
Besides, I don't want people to have to know whether their machine is paged
or swapped or segmented or linear before they can post to the net. I don't
want to see an endless chain of discussion as to what segmentation means.
I don't want to see the endless arguments about whether a given CPU is or
is not linearly addressed.
Choosing a newsgroup name is a political, not a technical process.
