These entries are packed, two for every three bytes. The contents of; entry number N is found by 1) multiplying N by 1.5; 2) adding the result to; the base address of the Allocation Table; 3) fetching the 16-bit word at this; address; 4) If N was odd (so that N*1.5 was not an integer), shift the word; right four bits; 5) mask to 12 bits (AND with 0FFF hex). Entry number zero; is used as an end-of-file trap in the OS and is passed to the BIOS to help; determine disk format. Entry 1 is reserved for future use. The first; available allocation unit is assigned entry number two, and even though it is; the first, is called cluster 2. Entries greater than 0FF8H are end of file; marks; entries of zero are unallocated. Otherwise, the contents of a FAT; entry is the number of the next cluster in the file.;; Clusters with bad sectors are tagged with FF7H. Any non-zero number would do; because these clusters show as allocated, but are not part of any allocation; chain and thus will never be allocated to a file. A particular number is; selected so that disk checking programs know what to do (ie. a cluster with; entry FF7H which is not in a chain is not an error).BREAK ;----+----+----+----+----+----+----+----+----+----+----+----+----+----+----;; C A V E A T P R O G R A M M E R ;; ;DIRSTRLEN EQU 64 ; Max length in bytes of directory stringsdpb STRUCdpb_drive DB ?
