INT 2F CU - Novell DOS 7+ FDOS EXTENSIONS - READ BUFFERS                        
	AX = 1002h
	CH = FFh (pre-read required)
	CL = buffer type (here FATsee File Allocation Table, DIR, or DATA, see below)
	AH:DX = 24 bit sector number
Return:	ES:SI -> buffer control block
Notes:	This private function is called internally by the OS kernel to
	  ask the FDOS to find the corresponding buffer.  By using the
	  INT 2F/AX=1001h FDOS hook, the call can be intercepted by external
	  system components such as the DELWATCH TSR(Terminate and Stay Resident) A program which remains in memory after terminating in order to provide services to other programs or the user.  The name comes from the name of the DOS function call used to remain in memory after termination..
	This function must under no circumstances be called by applications!
