No, the standard PC/XT floppy controller will NOT handle the 1.2 meg
5.25 inch format.  The 1.2 meg diskette requires that the controller
card be able to control drive speed (via pin 2 of the connector), and
be able to switch clock speed on the 765 controller chip.  Standard
5 1/4 inch formats as well as the popular 3.5 formats all use a 4 mhz 
clock, while the 1.2 meg format uses 8 mhz.
