Michael Brown 57b5e227ff Use fast in-situ test for gate A20 being set, to cut down on the ... number of (potentially very slow) gateA20_set operations. Die with a fatal error if we are unable to set gate A20; if this fails then we are bound to experience memory corruption at a later stage, and I'd prefer to pick it up early.		2007-07-13 13:32:49 +01:00
