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 SeeAlso: INT 0A"CPU",INT 0E"CPU"
