31 ; Set this to return the A20 gate to its previous state, instead of
32 ; leaving it open. This has caused problems, because there appear
33 ; to be a race condition between disabling the A20 gate and trying to

35 ; after we have already done the A20 enabled check, with disastrous
36 ; consequences. Plus, there seems to be little or no demand for it.
