[G4] Panther install question

[Ray Clayton]

I've finally decided to upgrade to OSX‹Panther disks on the way. But I'm
wondering if I should anticipate a problem with creating my account.

I bought the G4 used on eBay and although I've only used 9.2.2, it already
had 10.1 installed also. I remember the original owner's name, but, of
course, I don't know his password. What problems should I anticipate?
Workaround?

Or will the setup Assistant allow me to create my Administrator Account?
