Int 2F/AX=4A11h/BX=0004h

DBLSPACE.BIN - DSSetEntryPoints - SET DEVICE DRIVER ENTRY POINTS

AX = 4A11h
BX = 0004h
CL = drive number (0=A:) of compressed drive
DL = unit number for new driver entry points
DH = 00h
ES:SI -> device driver strategy routine to call for drive
ES:DI -> 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
