The 8086 should not really be able to figure this out. Because the processor/coprocessor interface between the 286 and 287 is so much different than that between the 86 and 87, I am not surprised that it does not work. The 286 does have the capability of trapping upon recognition of an ESC instruction via a couple of bits in the MSW. I have heard, however, that current AT software doesn't support that kind of thing. Mike McNally ...convex!smu!mike
