Just a note that the ELKS list has been a little depressed lately. So if you want to build a small unix like device on a PIC emulating an 8086 ;-) you might want to go look at http://www.elks.ecs.soton.ac.uk/ to keep things ticking over. seriously I don't think it will fit on a PIC, here's some info The goal of the ELKS project is to create a Linux option for 8086 and 80286 class PC's Palmtop Computers Single board microcomputers Embedded controller systems Other old computers ELKS currently runs on PC's. The ELKS kernel image needs about 200K and a full running system should require 400K-512K cya, Andrew... > -----Original Message----- > The 32 bit version of Linux does, but ELKS in being developed to run on > 80286 down to 8086, and portable to other architectures without an MMU. > They've even managed to get linux (mostly) working on Psion's sixteen bit > organisers such as the 3a and 3c etc. I'm pretty darn sure you couldn't > get linux to fit into any 16x PIC, but maybe the new 18C series??
