Int 2F/AX=4A11h/BX=0003h

DBLSPACE.BIN - DSGetEntryPoints - GET DEVICE DRIVER ENTRY POINTS

AX = 4A11h
BX = 0003h
CL = drive number (0=A:) of compressed drive

Return:
CL = FFh on error (not compressed drive)
CL <> FFh driver unit number of host drive
ES:SI -> device driver's strategy routine
ES:DI -> device driver's interrupt routine
BX destroyed

Note: In conjunction with subfunction 0004h, this call allows disk caches like SMARTDRV to apply a device driver wrapper to DoubleSpaced drives just like SMARTDRV applies to regular block devices
