Summary: DOS and anything but "normal" drives.


n order to use anything but a 5 1/4" drive on an XT or AT
you must perform a couple of extra steps in order to use it
in anything but 360K format.  DOS keeps track of the devices        
installed and then the programs make use of that info to 
perform whatever task is necessary.  The format program
accesses this table to determine how to format the drive.
In order to bypass this table, you can do one of the two  
following steps:
  device=driver.sys /d:1 /f:2
this will add another drive (d if you have a hard drive) that
is now a 720 K device. 
  drivparm=/d:1/f:2
this will make the b drive a 720K device.  The second example
will only work under DOS 3.2
