INT 2F U - MS-DOS 7 kernel - GET ???                                            
	AX = 1612h
Return: AX = 0000h if supported
	    ES:BX -> DOS 7 kernel data (see #02641)
Note:	called by VTD.VXD; one of the returned data items is a pointer to the
	  WORD in which the default CLOCK$ driver maintains its count of days
	  since 01jan1980

Offset	Size	Description	(Table 02641)
 00h	WORD	structure revision??? (0001h)
 02h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	-> ??? function (call with DS=high word of this field)
		the indicated function vectors through the INT 13 hook at
		  0070h:00B4h and then forces the A20(Address line 20) The 80286 and higher CPUs allow addresses in real mode to extend slightly beyond the one megabyte mark, which causes an incompatibility with some older programs which expect such addresses to wrap back to the beginning of the address space.  For complete compatibility with the 8088, newer machines thus contain circuitry which permits the twenty-first address line (A20) to be disabled.  The CPU then effectively has only twenty address lines in real mode, just as the 8088 does, and addresses which would extend beyond the one megabyte mark wrap to the beginning of the address space.
