Windows 98SE Product Key

Recently I have started playing with Ghost to
deploy a couple of new PC’s with Win98SE. I
want to ensure that licensing-wise, everything
is as legit as possible.

After creating the master image and ghosting
it to the other PC’s, the product key and its
resulting serial number are the same
(obviously) as the master. I know how to
change the product key in the registry but
since I didn’t actually have to enter the product
key with each PC install, how can I determine
whatserial would be generated based on the
product key? Is there a program out there
somewhere that will do this?

Any help is appreciated.
