9 * - Driver now works interrupt driven
10 * - Support for two drives; should work, but I cannot test that :-(
11 * - Reading is done in whole tracks and buffered to speed up things
12 * - Disk change detection and drive deselecting after motor-off
14 * - Autodetection of disk format (DD/HD); untested yet, because I
15 * don't have an HD drive :-(
18 * - Autodetection works now
