If you cannot modify your BIOS, Z3-DOT-COM is about your only option.
This is a commercial product from Echelon, and it takes only a few
minutes to install.  It creates a COM file that contains a Z-System.
On cold boot, run the COM file and it installs a Z-System in memory.

This option lacks the full functionality of the Z-System, and users
(in my experience) often want to later create a manually-installed Z-System
to pick up on the lack of functionality.  However, it is an easy out,
does not require a BIOS modification, and is a minimum of hastle (very small
learning curve and very little installation overhead).

There is a possibility that an RS Model 4 installation of ZCPR3 is
available, but I don't really know.  Echelon is the source to contact for
installation-specific questions.
