INT FE - AT/XT286/PS50+ - destroyed by return from protected mode
Note:	the ROM BIOS uses 0030h:0100h as the initial stack on startup, which
	  is the last fourth of the interrupt vector table.  If the processor
	  is returned to real mode via a hardware reset (the only possibility
	  on an 80286, though there are a number of ways of generating one),
	  then the BIOS startup code stacks three words on its scratch stack
	  before determining that a return to real mode has been requested.
	  As a result, INT FE and INT FF are corrupted.
