INT 0B P - 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
