9 * - now no bugs(?) any more for both HD & DD
10 * - added support for 40 Track 5.25" drives, 80-track hopefully behaves
11 * like 3.5" dd (no way to test - are there any 5.25" drives out there
13 * - wrote formatting routine (maybe dirty, but works)
15 * june/july 1995 added ms-dos support by Joerg Dorchain
17 * - currently only 9 and 18 sector disks
19 * - fixed a bug with the internal trackbuffer when using multiple
21 * - made formatting a bit safer
22 * - added command line and machine based default for "silent" df0
