The AT keyboard "write to mouse" command now returns 0xFF (error) when no PS/2 mouse is attached - fixes hangs on AOpen AP53, ASUS P/I-P55T2S, and Tyan Titan Pro/ATX when not using PS/2 mouse; Fixed the emulation of the SMC FDC37C669 Super I/O chip - serial ports now work correctly on the AOpen AP53 and the ASUS P/I-P55T2S.
