I did before I posted the message. The only prefix allowed is the REP (repeat) prefix. If I had a scanner, I'd send you the two pages 26-227, 26-228 of the Intel Rag, Intel 486 Microprocessor Familt Programmer's reference manual. ISBN 1-55512-159-4.
It is the movs[bwd] string ops that can use a segment override. That's on page 21-214 of the same rag
