Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     This function call can be captured by a program so that it will be
     notified as each cylinder is formatted or analyzed. The program
     can count interrupts for each phase to determine the current
     cylinder number.
 
     The ROM BIOS default handler for this function returns with the
     carry flag set.
