On an xt, to make it recognize a 720K disk, you can either use driver.sys
(which will add an additional drive to the end of your drive letter chain
to handle the proper drive, so that perhaps your a: drive would be 360K,
and your d: would be a 720K drive.)
Or as you say, use driveparm (which is supposed to replace the current
drive setting with the new parameters.)  In any case, I'm not sure you can
boot from a drive that has been driveparm reconfigured, since the
reconfiguring won't take effect until after the system is already loaded.
In dos 3.3, you needed to use an undocumented feature of 3 ctrl-a
characters to make it behave, though I believe in later dos versions, this
is no longer necessary.  In any case, I have no need for driveparm
anymore, so I can't help you directly with it other than to say try the
documentation (assuming driveparm is documented now) it didn't used to be.
