x86 Assembly Reference Sheet

Question

In my latest quest to learn some assembly language I'm finding myself constantly going to the web to find the definitions or descriptions for a particular register or mnemonic, ect.

I'm looking for a handy Reference Sheet that I can print up and refer to every time I see a symbol and I "can't quite remember" what it was.

Has anyone come across something like this on the web for themselves?

Thank you, this is the nuts! (It's a beautiful cheat-sheet on two sides of A4). – Robin Pain Apr 03 '12 at 12:03

The one Jeff linked is good, but it's covering 80186 too, which I think bloats it a bit.

For GNU as on i386 I recommend this one: gcc x86 Assembly Quick Reference ("Cheat Sheet")

Remember the length suffixes, covered here! The other one uses wide registers but doesn't use long operands.
