d5b13d3131 - second set of changes to bochs floppy support. 
* floppy command 'format track' implemented
  * read and write operations with MT=0 are working now
    (function 'increment_sector()' updated)
  * result code of floppy command 'get status' fixed
  * flag FS_MS_DIO is not set while the 'configure' floppy command is pending

328bd4fb84 - fixed the behaviour of some floppy commands (Windows 95 driver works now) 
* diskette controller data register returns last result if no new data
    is available
  * reset will be activated when the reset bit is changed to normal operation
  * reset sets the error bits in status register 0
  * write access to port 0x3f4 will cause a BX_ERROR now
  * unsupported and invalid floppy commands are setting the error status bit
    'invalid command' - BX_PANIC not necessary
  * flag FS_MS_DIO is not set while a floppy command is pending
  * floppy command 'specify': cause a BX_ERROR when non-DMA mode is selected
  * floppy command 'sense interrupt status' returns an error is no interrupt
    is pending
  * floppy command 'read ID' sets the 'busy' flag and returns no data if the
    motor is not on
  * removed SIMX86 section (not defined in bochs)
  * define variable 'sTemp' for win32 only
