16dfd66163 - floppy read/write commands: return value of status register 1 is 0x85 when
the requested sector doesn't exist.
- BX_PANIC message for requested cylinder > tracks on media fixed

a6d07ad166 - added support for 360k floppy images
* new floppy type 360k can be used in .bochsrc and the config interface
  * media type and geometry can be set for the floppy type
  * BIOS changes to make 360k floppy drives work
  * bximage can create 360k images now

68d3969bc4 - floppy read and write function do not set the 'seek end' bit in status

88f0e1b73f - init(): initialize media type for all 4 drives
- init(): set the initial status to BX_EJECTED if evaluate_media() fails
- don't modify the DOR when a drive > 1 is selected
- floppy command 'get status' now recognizes the head field
- floppy command 'recalibrate': don't set cylinder to 0 before completion
- floppy command 'sense interupt status' does not clear status register 0
- floppy command 'configure': more detailed BX_DEBUG messages
- floppy command 'read ID' does not modify status register 0
- floppy read/write commands: set the error bit in status register 0 if media
  is not present
- better detection of not existing drives in some commands: check the media type
  of the selected drive instead of the drive select value
- behaviour of floppy commands 'recalibrate' and 'seek' changed:
  * drive is busy in the execution phase, but not the controller
  * replaced the panic by setting the error status if drive is not existing
- evaluate_media(): set the media type even if device/file is not present

a51a7840e5 - floppy command 'read ID' now recognizes the head number bit

43f9f8287b - the skip flag (SK) in command 'read sector' is ignored now. The floppy
command codes 0x46 and 0xc6 are using the normal read function.

c7c9cc2430 - DMA register and unregister functions for DMA channels added and macros for
DMA functions defined. Most of the changes are based on the "bochs sync"
   version of plex86. Here is the list of changes:

  * register/unregister functions for DMA channels added. The DMA controller
    can use the DMA read/write handlers of registered devices directly.
  * "hardwired" code in dma.cc removed
  * all DMA related code in devices.cc and iodev.h removed
  * DMA related code in pc_system.* removed except HRQ handling
  * macros for DMA functions defined in bochs.h
  * floppy and SB16 code modified to use the changes described above

2892dbdb08 - track0 bit added to the result of the 'get status' command
- length of 'configure' floppy command fixed
- busy flag is set until the result of a read/write command is complete

- commented BX_INFO statements removed

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

ec0fbf18bc - convert nearly all bx_options to parameter form. All options that have
been converted into parameters temporarily have the letter "O" appended
  to their name.  I don't want to keep it this way, but it has helped
  in the conversion process because the compiler refuses to compile the
  old uses of the name.  Before I started using the "O" trick, there were
  many bugs like this:   if (bx_options.diskc.present) {...}
  This was legal with the new parameters, but it was testing whether the
  parameter structure had been created, instead of testing the value of
  the present parameter.  Renaming present to Opresent turns this into
  a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid.  I can no
  longer support this and continue progress.

7a095b60e4 - now floppy controller returns a proper error response if you try to write
a read-only disk image.  For systems such as DOS that actually use the
  BIOS services, it was also necessary to add code in int13_diskette_function
  to recognize a write-protected error and return the correct error
  status code (AH=3, Carry Set).

6ecd58beb9 - NOT A COMPLETE FIX!
now floppy.cc no longer crashes if you try to open a write-protected
  disk or read-only disk image.  Instead, it tries a second time to
  open the image read-only and only panics if this also fails.  If the
  image is opened read-only, a readonly flag is set
  (bx_floppy.s.media[drive].read_only).  If you try to write the floppy
  when this flag is set, the write silently fails except for some messages
  into the log.  Instead of failing silently we should learn what the
  floppy controller would really do in this situation and emulate it.

bdb89cd364 merge in BRANCH-io-cleanup.
To see the commit logs for this use either cvsweb or
cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files.

In general this provides a generic interface for logging.

logfunctions:: is a class that is inherited by some classes, and also
.   allocated as a standalone global called 'genlog'.  All logging uses
.   one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this
.   class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros
.   respectively.
.
.   An example usage:
.     BX_INFO(("Hello, World!\n"));

iofunctions:: is a class that is allocated once by default, and assigned
as the iofunction of each logfunctions instance.  It is this class that
maintains the file descriptor and other output related code, at this
point using vfprintf().  At some future point, someone may choose to
write a gui 'console' for bochs to which messages would be redirected
simply by assigning a different iofunction class to the various logfunctions
objects.

More cleanup is coming, but this works for now.  If you want to see alot
of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1.
