INT 60 - Nabbit v2.0 - (NOT A VECTOR!) - INSTALLATION CHECK
Program: Nabbit is a shareware resident screen data grabber by RSE Inc.
Range:	INT 60 to INT 66, selected by searching for first free vector
Note:	the Nabbit installation check consists of testing whether the
	  interrupt vector points at the ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. signature string "iG"
	  (69h 47h 00h)
                                                                                

INT 60 - ATI M64VBE.COM - INSTALLATION SIGNATURE                                
Program: M64VBE is a VESA(Video Electronics Standards Association)  An industry group which sets both hardware and software standards and recommendations. The term VESA is also used to denote compliance with the VESA SuperVGA BIOS Extensions, a standard set of video BIOS functions for accessing video modes of higher resolution than those defined by IBMInternational Busiuness Machines. VBE(VESA BIOS Extensions) The common software interface for video cards providing support for high resolution and bit depth. 2.0 driver 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. for ATI's Mach64 video chip
InstallCheck:	scan for an interrupt with the ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. signature "M64VBE" three
	  bytes past the interrupt handler
Range:	INT 60 to INT 66, selected by searching for first free vector

INT 60 U - Buffit v3.0 - (NOT A VECTOR!) - INSTALLATION CHECK
Program: Buffit is a shareware scrollback utility by D.T. Hamilton
Range:	INT 60 to INT 6F, selected by searching for first free vector
Notes:	the Buffit installation check consists of testing whether the
	  interrupt vector points at the ASCII signature "Buffit  "
	there is a private entry point (see #03267) immediately following the
	  signature string, i.e. eight bytes beyond the address pointed at
	  by the interrupt vector


(Table 03267)
Call Buffit private entry point with:
	AH = function
	    00h get information and hotkey state
	    01h get information and toggle hotkey state
Return: AH = new hotkey state (00h enabled, 01h disabled)
	AL = hotkey scan code (see #00006)
	BH = hotkey shift states
	BL = ??? (01h)
	CX = segment of resident code
	DH = interrupt number used for signature pointer
	DL = ??? (00h)
	SI = INT 09 handler offset
	DI = INT 21 handler offset
