INT 13 - SWBIOS - SET 1024-CYLINDER FLAG                                        
	AH = EEh
	DL = drive number (80h, 81h)
Return: CF clear
	   AH = 00h
Program: SWBIOS is a 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. by Ontrack Computer Systems
Desc:	the following INT 13 call will add 1024 to the specified cylinder
	  number to get the actual cylinder number desired
Notes:	the flag is cleared by all INT 13 calls except AH=EEh and AH=EFh
	Disk Manager also supports these calls
	this function is also supported by HyperDisk v4.01+ and PC-Cache v5.5+,
	  in order to allow caching of drives using SWBIOS to access more than
	  1024 cylinders
	for software which supports that call, this function is equivalent to
	  calling AH=EFh with CX=0400h
