(Not that I can add much to the thread.) Other than the Minix, and split I/D discussion tickled an old memory..
I'd say it depends on the the version of Minix. My Google Foo Finds these two threads (quickly) WRT Minix & split I/D. http://www.verycomputer.com/79_f57ba779880523a6_1.htm https://groups.google.com/forum/#!topic/vmsnet.pdp-11/Azzk6fQHmLE The latter is funny in this context, that thread is only 12 years old.
