	AH = 20h

1321 - INT 13 u - QUICKCACHE II v4.20 - FLUSH CACHE

INT 13 u - QUICKCACHE II v4.20 - FLUSH CACHE
	AH = 21h
Return: AX = status (0000h successful)
Desc:	immediately write all dirty sectors back to disk
Note:	this is one out of several cache flush calls issued by the PTS-DOS 6.51
	  and S/DOS 1.0 kernel before rebooting. It is called with DL=80h and
	  conflicts with the PS/2 function of the same function number, because
	  the kernel does not perform Quickcache's installation check first.

Notes:	most of the SMARTDRV API, including this call, is supported by
	  PC-Cache v8.0 and recent versions of the Norton Caches
	the internal name for SMARTDRV is "BAMBI", hence the magic "BABE".
	if DBLSPACE.BIN is installed but SMARTDRV has not yet been installed,
	  then calls of this function with CX<>EBABh on entry cause
	  DBLSPACE.BIN to display the error message
	  "Cannot run SMARTDrive 4.0 with DoubleSpace" and abort the caller
	  with INT 21/AX=4C00h
	Since the Novell DOS 7 - DR-DOS 7.03 NWCACHE supports a similar 
	  install check at this function, but the returned registers
	  contain different data, the caller must take the returned AX value
	  into account to ensure proper interpretation of the returned info.
	  The caller should ensure CX <> 0EDCh to avoid any interaction
	  with the NWCACHE and COMMAND.COM special case of CX=0EDCh.
	  Although this is an install check, NWCACHE always flushes delayed
	  writes to disk, when calling this function with CX<>0EDCh or while
	  /FLUSH:ON is active, but this is nothing to rely upon. The reason
	  for this could be to get more accurate statistics, while SMARTDRV
	  just takes a on-the-fly snapshot of the statistic vars.
	The private NWCACHE/NLCACHE install check INT2Fh/D8C0h does not flush
	  to disk, and therefore can be used by callers that must ensure
	  the buffers aren't flushed on this function (e.g. alternative
	  command shells may need this to make their "flush before prompt"
	  feature configurable).
	The NWCACHE 0EDCh special case will most probably vanish with
	  future issues of NWCACHE (2.0+).
	SMARTDRV v3.x had a completely different API using IOCTL calls, which
	  was also supported by the Norton Caches
BUG:	Although DS and ES registers are listed as unmodified, some
	  releases of SMARTDRV seem to trash the DS register, at least the
	  MS-DOS 6.2+ KEYB takes care to preserve the DS register when calling
	  this function.

Notes:	SMARTDRV 4.0+ uses a similar installation check on this function but
	  returns different data.  To ensure proper interpretation of
	  the returned values, the caller must check the returned magic
	  value in AX. Since SMARTDRV may also alter DI:SI (and possibly
	  DS), the caller should take care of this, too.
	The Novell DOS / DR-DOS 7.x COMMAND.COM invokes this function with
	  CX=0EDCh, which causes NWCACHE to flush any delayed writes before
	  returning the normal register values if it is configured to flush
	  writes before returning to the DOS prompt (/FLUSH:ON); however, if
	  /FLUSH:OFF, this function becomes a NOP with CX=0EDCh.
	Note that for this function the 0EDCh special case may vanish with
	  future issues of NWCACHE (2.0+), and the function would then always
	  do the normal install check, and not flush the cache.

Notes:	If the read cache is off, reads will not be cached, but writes will

	SMARTDRV flushes the cache if sub-functions 02h or 04h have been

	On calling this function, NWCACHE flushes any delayed writes,
	  but you should not rely on this, since this behavior may vanish
	  in future versions.
BUG:	The MS-DOS 6.20+ SCANDISK disables a SMARTDRV 4+ compatible cache
	  for the drive it is about to process.  However, at least when the
	  cache loaded is NWCACHE, the cache will still remain disabled for
	  this drive after SCANDISK has finished.  The reason for this behavior
	  is not yet known. The workaround is to re-enable with the
	  NWCACHE d:+ syntax afterwards, where d: is the corresponding
	  drive letter.
