You can find more information on direct access to de Floppy Disk Controller
in :
1. The 80XXX_95 (1995 Asm Code Snippets From Fido'S 80xxx Echo.)
   Take a look in \FDC\README :
   /* (README)
   This directory contains files related to floppy disks.
   fdcdemo.asm     code for direct programming of IBM PC FDC, with CLI that
           can read, write, and format a variety of disk types, and can
           copy between disks and image files
   fdcdemo.com     executable of above demo program
   fdcdemo.txt     documentation for above
   fmt179x.asm     disk formatter for WD179x FDCs (for CP/M)
   floppy.mar      disk I/O routines for WD1771 FDC on MicroVAX
   format.mar      disk formatter for WD1771 FDC on MicroVAX
   */
2. You can try to study to source of 2M and 2MGUI, because 2M(GUI) also
   make use of programming the FDC directly.
   Take a look at : http://www.gui.uva.es/~ciri/
3. I have done some little experiments by studying the source of 2MGUI and
   reading some info in a book "The Undocumented PC". With this information
   I have written a very little experiment that can detect which 'Diskette
   Controller IC' is used in your PC. I'll post the source of this
   experiment in the next message.
MB> Bye Bye , Maurizio.
Have a nice day.                       - Jan Wagemakers -
