Description         :       Installing OS/2 2.0 on an

       After installing OS/2 version 2.0 in an IBM PS/2 model 80-16
       MHz with an IBM memory expansion board part # 90X90369, one of the 
       following problems may occur  :

			      ????

	Solution        :       No solution is available at this time.

II      When operating OS/2 in an IBM PS/2 model 80-16 MHz with the IBM PS/2 
	Enhanced 80386 Memory Expansion Option and the Arco AC-1070, the 
	system will hang up at the OS/2 logo display.

				option to disabled.
