INT 13,9 - Initialize Fixed Disk Table (XT & newer)

	AH = 09
	DL = fixed disk number	(80h=drive 0, 81h=drive 1)


	on return:
	AH = status  (see INT 13,STATUS)
	CF = 0 if successful
	   = 1 if error


	- sets specified fixed disk table to the default values from ROM
	- many good programming references indicate this function is only
	  available on the AT, PS/2 and later systems, but all hard disk
	  systems since the XT have this function available
	- INT 41h vector is pointer to table for drive 0
	- INT 46h vector is pointer to table for drive 1
