Toivo Henningsson, depending on the range of numbers you're multiplying you can actually improve significantly on the hardware multiplier at the cost of using memory for tables. I wrote about such a technique at https://www.reenigne.org/blog/multiplying-faster-with-squares/ . The timings there are for 8088 rather than 8086 - the speedup should be even more significant on 8086 especially if the accesses are word-aligned.
