Huh?  The 286 has memory protection and 386-like segment descriptors,
but it's a 16 bit processor through and through.  It has a 16-bit ALU
with 16-bit registers, and addresses within a segment are 16 bits.
Yes, there were versions of Unix that ran on it, which isn't too
surprising given Unix's origins in the 16-bit PDP-11 world.  I'm not
aware of a Linux port to it, unless you mean something like ucLinux.
