test and set lock

[Ozguxxx]

Hi is there an intel version of the tsl instruction that tanenbaum tells about in his book?
TSL: Test and set lock
----------------------------
Copies value of some memory location to a register and sets a new value to this memory location. All this is done atomically.

Have you lookd in the Intel manuals yet? Volume 2 would be your best bet.
