T13/2132-D Revision 3 June 23, 2010 Approval of an American National Standard requires verification by ANSI that the American requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI National Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple Standard majority

June 23, 2010 T13/2132-D Revision 3 Foreword Foreword (This foreword is not part of American National Standard NCITS.xxx-200x) DOS accesses its mass storage devices using an INT13h programming interface provided by BIOS firmware to higher-level software. This interface was designed in the early 1980's, upgraded in the late 1980's and upgraded again in the early 1990's. Initially, INT 13h used a cylinder-head-sector interface that was limited to approx. 528MB of disk addressing. Later thi
