		BL = ???
		Return: if BL nonzero on entry
			    DX:AX -&gt; ???
			if BL = 00h on entry
			    ES:SI -&gt; ???
Notes:	DOSSHELL chains to the previous handler if SI is not one of the values
	  listed above
	the DOSSWAP.EXE module calls functions 03h,04h,05h,07h,08h,09h,0Ch
	the Windows 3.1 DSWAP.EXE and WSWAP.EXE task switchers use these calls
