<pre><b>INT 2F - DBLSPACE.BIN - "DSSetEntryPoints" - SET DEVICE DRIVER ENTRY POINTS</b>

	AX = 4A11h
	BX = 0004h
	CL = drive number (0=A:) of compressed drive
	DL = unit number for new driver entry points
	DH = 00h
	ES:SI -&gt; device driver strategy routine to call for drive
	ES:DI -&gt; device driver interrupt routine to call for drive
Return: CL = FFh on error (not a compressed drive)
	BX destroyed
Program: DBLSPACE.BIN is the resident driver for DoubleSpace, the
	  disk-compression software bundled with MS-DOS 6.0
Note:	in conjunction with subfunction 0003h, this call allows disk caches
	  like SMARTDRV to apply a device driver wrapper to DoubleSpaced
	  drives just like SMARTDRV applies to regular block devices
