===Don't use LOOP===
This doesn't affect the 16-bit 8086, but <code>LOOP</code> has some quirks where it's much more efficient to use:
<lang asm>label:
;loop body goes here
DEC ECX
JNZ label</lang>
Which is very ironic considering that <code>LOOP</code> was originally designed to be a more efficient version of the above construct. (It was more efficient in the original 8086, but not in today's version.) Thankfully, compilers are "aware" of this and don't use <code>LOOP</code>.
