If would not be a problem to load the tables if you define the initial values in the segment shadow registers. Assume that all segments would point to some segment at a given physical address (e.g. 0), have a given limit (e.g. 4 Gigabytes) and some reasonable protection settings. Now define that interrupts are disabled after reset. The first thing that you could do were to setup the tables that you need.
