note 1) When an alternate keyboard handler is invoked, the keyboard routine is  
	loaded into user memory starting at the lowest portion of availible  
	user memory. The BIOS interrupt vector that services the keyboard is 
	redirected to the memory area where the new routine resides. Each new 
	routine takes up about 1.6K of memory and has lookup tables that return 
	values unique to each language. (KEYBxx in the DOS book) 
	 Once the keyboard interrupt vector is changed by the DOS keyboard 
	routine, the new routine services all calls unless the system is  
	returned to the US format by the ctrl-alt-F1 keystroke combination. This 
	does not change the interrupt vector back to the BIOS location; it 
	merely passes the table lookup to the ROM locations.  
     2) Ctrl-Alt-F1 will only change systems with US ROMS to the US layout. 
	Some systems are delivered with non-US keyboard handler routines in ROM 
     3) Case mapping call: the segment/offset of a FAR procedure that performs  
	country-specific lower-to-upper case mapping on ASCII characters 80h to 
	0FFh. It is called with the character to be mapped in AL. If there is 
	an uppercase code for the letter, it is returned in AL, if there is no 
	code or the function was called with a value of less than 80h AL is 
	returned unchanged. 
     4) This call is fully implemented in MS-DOS version 2.01 and higher. It 
	is in version 2.00 but not fully implemented (according to Microsoft)
