Look on page 62 of _Programmer's Guide to the IBM PC and PS/2_:

	In the PC/XT/AT family, the 16 bytes starting at 0040:00F0 are
	reserved as an intra-application communication area (ICA).

Norton also gives a warning that some versions of the _IBM PC Technical
Reference Manual_, through a typographical error, list the address as
0050:00F0.
