Changes to V1.4 (05/21/96)
--------------------------------------------------------------------------
* Fixed problem when only a single floppy was selected.

* Fixed problem with AMIA being ignored.

* Added four new video drivers.  Two of these drivers (Multiscan and
  eMultiscan) are AGA-only and let you have 'thousands' and 'millions'
  mode using special tricks with the AGA hardware.

  The 'WorkbenchVideo' driver allows you to open the MAC on a Workbench
  window in 2 through 256 color modes.  If your machine does not support
  256 colors, you can still have the MAC select a 256 color display (color
  approximation is then used to match pixel colors).  You can use standard
  Amiga video or video board promoted video.

  The 'AmigaMonoVideo' driver is for those wanting to free up MAC memory
  (driver requires only 64K of memory) and is a 'direct access' driver.
  Note: This driver requires OS 3.0 or later.

* Added support back in for the 'QD' video drivers.

* Changed LocalTalk routines for 512K/1mb ROMs.

* Changed CPU speed calculation routine to reflect proper speeds
  with all processors (especially the 060).

* Removed a very critical typo, which left the interface and internal
  routines in a disabled state the entire time the emulation was running!
 
* Fixed shutdown crash/hang.

* Fixed CD-ROM device name entry handling.

* Fixed problem with setting foreground refresh rate (it was always
  60 FPS, reguardless of what it was set to).

* Enhanced amiga sided serial and parallel handling.

* All new empdisc.device and CD-ROM setup.  You can now select a cache
  size for the CD-ROM device, and what type of memory to use.  If you
  are using a controller that DMAs data directly, select CHIP memory
  as the memory type.

  A complex caching alogrythm is used to achieve incredible performance,
  even though double-buffering is NOT used (thus saving memory).  The
  cache size is adjustable from 4K to 128K.

  Remember, the larger the cache size does NOT always mean the better
  the performance.  We have found that 8K of cache is actually best
  for 40Mhz 040 machines with 2x CD-ROM drives.  If your CD-ROM drive is
  a 4x or 6x speed, a larger cache size will help performance
  dramatically.  Too large of a cache selection with a slow drive, or
  slow Amiga system will result in poor performance.  Experiment!

* Fixed parameter ram problems with 256K ROMs and real SCSI devices.
  It was possible that you could not boot off of the EMPLANT's SCSI
  port if there was no existing pram256.config file.

* Fixed 060 AppleTalk problems.
