INT 0B - CPU-generated (80286+) - SEGMENT NOT PRESENT

Desc:	generated when loading a segment register if the segment descriptor
	  indicates that the segment is not currently in memory, unless the
	  segment is an LDT (see INT 0A"CPU") or stack segment (see
	  INT 0C"CPU") needed by a task switch
Note:	may be used to implement virtual memory by loading in segments as they
	  are accessed, clearing the "not present" bit after loading
