Removed the incorrect implementation of the OPTi 495 register 0x27 bit 7, it had nothing to do with A20, and the A20 stuck error was caused by the previously incorrect implementation of the 8042 output port bit pulse commands which is no longer the case;
The 8042 now once again correctly initializes with A20 Gate on.
