I have an old PC6300 with the 1.43 ROMs. It currently has two 5" 360k drives, but I want to replace one of them with a 3.5" 720k drive. If I make *both* drives 720k, I can flip a dipswitch on the motherboard and all is supposed to work well. I just one *one* of them to be 720k. Can anyone offer any advice on this? -- Doug DeJulio dd26@andrew.cmu.edu

Simply install the 720K FDD as either A or B, then use the DRIVPARM feature in DOS (3.3 & up) to inform DOS that the physical drive is not a 360K FDD, but a 720K FDD.
