[comp.sys.ibm.pc] upgrade DOS on HD.

Hi,
  I have a 20M HD and it was formatted into three partitions with a program
called PARTED by a friend who doesn't live close to me anymore. Now that I
want to upgrade the DOS from 3.2 to 3.3. What should I do? Can I just delete
the old IO&BIOS files and replace them with the new ones? or can I use FORMAT
to format just the dos partition? I want to have it done without re-install
every programs again. Any ideas?
