2e8dccf684 - fixed floppy return status if media not present (MS-DOS expects value 0x80) 
- more accurate handling of the floppy recalibrate function (removed panic)
- small code cleanups and optimizations in the floppy code (e.g. do .. while loops,
  always using 0040:003e for the floppy interrupt flag)
- small updates ported from the PC BIOS project
