using both the LBA and CHS large drive remapping method. In addition to supporting
standard drives through an auto-configuration process that does NOT require user
involvement or confirmation. The system should automatically do this at POST time in a
way that is transparent to the user. If a drive is connected to the bus, the drive should be
automatically recognized, configured and available for use under MS-DOS 6.2x.
