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. -- Paul Vixie Digital Equipment Corporation Work: vixie@dec.com Play: paul@vixie.UUCP Western Research Laboratory uunet!decwrl!vixie uunet!vixie!paul Palo Alto, California, USA +1 415 853 6600 +1 415 864 7013
