  or request register

d5b13d3131 - second set of changes to bochs floppy support.

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

condition, so I've removed it now.

e5a992a796 - master PIC ignores commands 0xc0-0xc7. This change just makes the slave 
PIC ignore these same commands.  It does not implement the commands.

94ba0f4ca4 - remove some "#if BX_DEBUG" lines. What are these anyway? They've 
probably been treated as ifdef instead, but a sun compiler doesn't like
  them.  Anyway, they were being used around a check for irq_num > 15.
  This bounds check seems ok to do all the time, so I just removed the
  #if BX_DEBUG lines and corresponding #endifs.

c52fbaa3a7 - allow configuration of the parallel port in .bochsrc and the config 
interface menus.  Parallel port #1 is implemented, and I left stubs for
  parallel port #2 in case we want to ever add it.  If the parallel port
  is enabled, the init method of parallel.cc does an fopen() on the output
  file.  If disabled, or if the fopen fails, the file handler remains
  NULL and no characters are printed.  There is no attempt to enable/disable
  the operation of the parallel port, only the output to a file.
