Can you find some system which can be booted from your 5.25 disk and have
3.5 disk driver tied to it?  If you can find one, boot from your 5.25 disk.  
Then format/s your 3.5 disk and then transfer the files from the 5.25 disk
to the 3.5 disk.  (The problem is that many systems don't boot from a lower
lever dos.)

I did this way for dos 2.0 (or 2.1?) disk.  The 3.5 disk was formated
into 360k.

(Another way to do it, if there is nothing about system files, you may try
to use PC Copy II.  I am not sure if it works or not for the system files.)
