Absolute Disk Read

Absolute Disk Read ; ; Synopsis: int getsec(drive,numsec,begsec,buffer) ; unsigned int drive; /* 0=A, 1=B, etc. */ ; unsigned int numsec; /* Number of sectors to read */ ; unsigned int begsec; /* Beginning logical sector */ ; char *buffer; /* Transfer address */ ; ; Function: The number of sectors specified are transferred  ; between the given drive and the transfer address.  ; LOGICAL SECTOR NUMBERS are obtained by numbering ; each sector sequentially starting from track 0, head 0, ; sector 1 (logical sector 0) and continuing along the ; same head, then to the next head until the last sector ; on the last head of the track is counted.  Thus,  ; logical sector 1 is track 0, head 0, sector 2, ; logical sector 2 is track 0, head 0, sector 3,  & so on. ;
