Interrupt 1Eh  Vector of Diskette Controller Parameters
(0:0078h)       Dword address points to data base table that is used by BIOS. 
		Default location is at 0F000:0EFC7h. 11-byte table format: 
		bytes: 
		00h     4-bit step rate, 4-bit head unload time  
		01h	7-bit head load time, 1-bit Not DMA flag
		02h     54.9254 ms counts - delay till motor off (37-38 typ) 
		03h	sector size: (bytes/sector)
			00h     128 bytes 
			01h     256 bytes 
			02h     512 bytes 
			03h     1024 bytes 
		04h	last sector on track (sectors/cylinder - 8 or 9 typical)
		05h     gap between sectors on read/write (42 typical) 
		06h     data length for DMA transfers (0FFh typical) 
		07h     gap length between sectors for format (80 typical) 
		08h     sector fill byte for format (0F6h typical) 
		09h     head settle time (in milliseconds) (15 to 25 typical) 
			DOS 1.0   0 
			DOS 2.10  15 
			DOS 3.1   1 
		10h     motor start time (in 1/8 second intervals) (2 to 4 typ.) 
			DOS 2.10  2 
Interrupt 1Eh  Vector of Diskette Controller Parameters
note 1) This vector is pointed to the ROM BIOS diskette tables on system  
	initialization 
     2) IBM recommends that if this table needs to be modified, it should be 
        copied into RAM and only the nescessary changes made.
     3) The Step Rate, Head Unload Time, Head Load Time, and DMA flag are set
	in the 8272, 8272A, or 82072 Floppy Disk Controller Chips using the
	SPECIFY command (03h). These parameters are already formated for the
	command as they appear in the Diskette Controller Parm table. Values
	for the time parameters are dependant on the Data Rate Speed set in the
	Data Rate Select Register and are documented in the Intel Product Line
	Handbook for Peripherals. For the Step rate higher values result in
	faster movement.
     4) The Bytes/Sector, Sectors/Cylinder, Gap, and Fill Byte parameters are
	used directly from the table by the FORMAT A TRACK command (0Dh or 4Dh)
	of the Intel 8272, 8272A, and 82072 floppy disk controllers
     5) Sample values for a DOS 3.3 machine are:
	  00: DF
	  01: 02
	  02: 25
	  03: 02
	  04: 12
	  05: 1B
	  06: FF
	  07: 54
	  08: F6
	  09: 01
	  10: 08
