Any better asm tutorial?

I have been searhing on the NET for some great asm tutorials but those guys only talk about the stuff like basic registers, segments/offsets, and some other basic stuff. I want to know more 'cause there is more coding involved in asm like "[cs:ds]" (I never understood what that was).
Anybody knows about about any good free tutorial or book (not Art Of Assembly)?

[ and ] mean the byte, word or dword at that memory location.

so..

Code:

---

mov al, [cs:80h]

---

would move whatever is at segment cs offset 80h into al.

And you cant to cs:ds because those are both segment registers.

Anything else?

Thanks chimp:)
I got it now...it's not that hard but it's hard to actually use this stuff when programming. Do you know any good tutorial or where did you learn all this stuff from 'cause I see you in this asm forum almost all the time?
