INT B6 - (NOT A VECTOR!) - USED BY TBFENCE
Program: TBFence is a security program by ESaSS B.V. which transparently
	  encrypts floppies and optionally allows only encrypted diskettes to
	  be accessed
Note:	the low word of this vector (0000h:02D8h) contains the segment of the
	  TBFence INT 13h code, which starts with the signature word E487h;
	  this forms the installation check
	the highest byte of this vector contains the start of a FAR JMP
	  instruction to ???
