Atleast with older ICH chips the TCO reset can be disabled in hardware
with a pull-up or pull-down resistor (I forget which) on one of the 
PC speaker lines.  They did this on a Tyan MB but I was able to remove
the resistor.  The thing that was strange is they didn't know why they
put the resistor on the board to disable it.
