INT 13 - SWBIOS - GET EXTENDED CYLINDER COUNT                                   
	AH = FEh
	DL = drive number (80h, 81h)
Return: CF clear
	DX = number of cylinders beyond 1024 on drive
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
Notes:	standard INT 13/AH=08h will return a cylinder count truncated to 1024
	BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. without this extension would return count modulo 1024
	Disk Manager also supports these calls
