You seem to be mistaken here. The ISA bus only supports 16MB but memory in
PCs does not reside on the ISA bus.  It resides on a dedicated memory bus.
True you can only add 16MB in an ISA bus but who would want to, since the
ISA bus runs at 8-12MHz and is much slower than the memory bus.

The limitation you talk about is not sofware (read - UNIX on a PC) but
the bus.  If you add 100MB of real memory on the dedicated memory bus in
a 386/486 machine it will be used by UNIX.

BTW - Did you know that there are more Intel bases machines running UNIX
or a UNIX variant (Xenix) than any other machine.
