XENIX-286 (and any other UNIX which runs in protected mode on the PC/AT)
requires memory boards which fill the 16meg address space of the 286, such
as the AST ATvantage and the AST RAMvantage. There are "generic" versions
of such boards, too, if the AST boards are too expensive for you.
The LIM and EEMS boards like the RAMpage and the Intel Above Board use
a kind of bank-switching, allowing DOS to map multiple pages of memory into
parts of the 640K address space of the 8086 and the 286 in real mode,
which is of no use for any version of UNIX on a 286.
