Keywords: RAM Memory Message-ID: <1540@draken.nada.kth.se> Date: 31 Aug 89 13:54:14 GMT Reply-To: d88-eli@nada.kth.se (Erik Liljencrantz) Organization: Royal Institute of Technology, Stockholm, Sweden Lines: 8 Several (or all?) AT's and 386's I've used that's equiped with 640Kb memory (or more) show up with 639Kb instead. Is this to allow for some protected mode table (a GDT or LDT for example) or why do I loose 1Kb? Just curious, Erik Liljencrantz d88-eli@nada.kth.se
