   My code is in C, but that appears to be the correct values to disable   
   NMI and clear CMOS 0Fh, followed by the required mandatory port read.   
      
   If you follow that cold by the 8042 Keyboard controller reset code that   
   Wolfgang posted, you should get a reset.   
      
   In this case, you've only set one of the two cold/warm reboot flags,   
   i.e., CMOS 0Fh, but not the BDA value at memory location 0472h.
