resetting username and password

[aurgathor]

What is the least destructive way to reset the username and the password on a 0.4.5 router?

A long time ago I set up a 0.4.5 box, but I never actually ended up using it because I had an older one that worked just fine. Today, a storm related power fluctuation knocked out my Freesco box that has been online for over a year, and due to a worn out floppy drive and/or floppy, it is not possible to hoot any more in the current state. I swapped the routers, and the new box appears to be working fine; however, I'm unable to log in.
I know, I know, I should've put a yellow sticky on it, but it's too late for that.

The install is on a hard disk, and the system dual boots Win 98SE and Freesco. I'm thinking about copying out the config files from the current install, reinstall with new username/password, and then replace the relevant config files.

TIA

All you need to do is to boot from a floppy or the with 98 system and copy a new version with a known password of the "c:\router\etc\passwd" file onto the system. There are no other password files except for the "htpasswd" file for the web interface.

Thanks, it worked.
